Gas Boilers vs Heat Pumps

Marcus Elliott • November 15, 2021

Changing how we heat our homes here in the UK is already out of our hands. By 2035 we will no longer have the option of choosing to install a gas boiler in our homes and businesses.


Our 2030 and 2050 milestones to UK Net Zero mean the question is now about the most practical, sustainable option to swap our gas boilers for. And it’s the same story around the globe.


Gas boilers have quietly hummed away like a background theme to our lives without us giving them much thought. Yet, if we don’t replace gas boilers with renewable options at a rapid pace, our use of fossil fuels is set to double by 2030.


Here in the UK, almost half the energy we consume is used to heat our homes and businesses. That means a national and global reduction in carbon emissions is highly dependent on each of us replacing our gas boilers with a renewable solution, which for the majority of us will be a heat pump.


Suitable for homes and businesses, heat pumps answer all the practical requirements we have for domestic and commercial heating. Indeed, mass installation of heat pumps, in the form of air source heat pumps and ground source heat pumps, is fast-impending across the UK and the world.


Let’s take a look at how heat pumps stack up against the many practical duties our gas boilers have delivered for so long.

Cost:

Let’s be honest. Good intentions aside, the first thing you need to know is whether you can afford a heat pump. Where renewable energy once looked like the preserve of the few, who were most likely to appear on the next season of Grand Designs, things have moved quickly.


Across the world in 2020, the IEA reports ‘almost 180 million heat pumps were used’ to hea homes and businesses. In 2021, demand for heat pumps rose by 28% here in the UK alone. In Germany, heat pumps have outstripped gas boiler use in homes with Spain, France and Italy following close behind.

It’s the same story across the globe from Iceland to Korea and the US. Demand for heat pump installation has increased 10% each year for the past 5 years, with an expectation that 600 million heat pumps will be installed by 2030 and 1,800 million by 2050, according to the IEA 2021 roadmap.


With the UK government fully behind the change and two thirds of us believing renewable energy should be rolled out across our buildings sooner rather than later, that’s good news for our pockets.


It will cost you more to install a heat pump at present but the UK government has already committed to bring costs into line with gas boilers in the coming years and there are financial schemes to lower costs

in place.

Financial support



The most popular is the Renewable Heat Incentive (RHI) which can be used for domestic and commercial installations. Under the scheme, you receive payments every three months in return for the low carbon heat your heat pump produces. The government has given a March 2022 end date for the scheme at present with the Clean Heat Grant beginning from April 2022. The Clean Heat Grant will give you a sizeable chunk of money upfront to slash the cost of installing a heat pump.

Rising boiler costs


On the flip side, it’s inevitable gas boilers in the UK and around the globe are going to become increasingly expensive for two reasons. Firstly, our attitudes as a global community towards our use of fossil fuels have changed dramatically in recent years and human over- consumption is no longer acceptable to most of us.



Couple that with UK and world government sign-up to 2030 and 2050 goals, with our commitment here in the UK now statutory, levies on fossil fuel use are clearly on the way with action on heating top of the list.


So although heat pumps cost more to install, there is financial help from the government to reduce initial costs, with the prospect of gas boilers soon becoming more expensive than heat pumps to purchase a reality.


Lower energy bills

Regardless, in the long run, initial costs for heat pumps are soon recouped, with ongoing financial savings due to the reduction in energy bills as well as financial reward from the government. Heat pumps run more efficiently so they give you more heat for less money meaning you’ll use less energy, reducing your energy bills long term.

That means heat pumps cost less to run than gas boilers with the prospect of cuts to your energy bills a welcome return on investment, particularly as fuel costs are on the rise.

Performance

Energy efficiency

Heat pumps are designed to be efficient so they outperform boilers when it comes to your heat supply too. Gas boilers deliver around 90% of the energy they consume to your home, the rest is wasted. Heat pumps on the hand give back around 300%, in some cases 400%, of the energy they use.


With installation of heat pumps including an energy efficiency review, you may also find there’s room to improve the performance of the building’s insulation. Gaps in walls and floors is money wasted, damaging the efficiency levels you can reap from your heat pump so you may choose to improve insulation as part of your milestones to sustainable living.

Heat pumps also improve efficiency by regulating the heat you receive. By delivering a more consistent temperature, instead of the sharp rise and fall we’re used to receiving from gas boilers, heat pumps give you a better, cheaper heat experience. Not to mention the advantages of contemporary built into the technology


Baths, showers and winter heating


Carefully regulated heat from a contemporary design means you can still receive adequate heat to run your home year round from a heat pump. Iceland has one of the world’s biggest takeups of heat pumps so clearly our winters are a cinch!

A heat pump system will still enable the family to continue with baths, showers and all the other heating requirement we’ve enjoyed from gas boilers.


Installation


Installation is easy, with the installation of air source heat pumps only taking a few days. For ground source heat pumps, the fitting of pipework in the ground beside the property means installation takes a little longer. ...more


Practicality


Heat pumps can be used in all weathers, just like gas boilers. Air source heat pumps must be installed in a safe and sensible place to protect them from harsh weather but that’s no different to the installation of any equipment.

The UK government has committed £6 billion to support the transition to a more energy efficient housing stock. This funding is being channelled through schemes such as the Social Housing Decarbonisation Fund (SHDF), ECO+, and the Boiler Upgrade Scheme (BUS). For councils, housing associations, and residents, these initiatives present a significant opportunity to upgrade homes, reduce carbon emissions, and tackle fuel poverty. The SHDF is one of the most important funding streams for local authorities and housing providers. It is designed to improve the energy performance of social housing, focusing on properties with the lowest EPC ratings. The fund supports insulation, heating upgrades, and renewable technologies, with the aim of bringing homes up to EPC C or better. Councils that act early can secure grants to deliver large scale programmes while meeting government targets for decarbonisation. ECO+, also known as the Energy Company Obligation Plus, extends support to a wider group of households. It targets those who may not qualify for other funding but still live in inefficient homes. Measures such as cavity wall insulation, loft insulation, and heating system improvements are covered, giving residents access to affordable upgrades. For councils and housing associations, ECO+ can be combined with other schemes to maximise funding opportunities. The Boiler Upgrade Scheme focuses on encouraging the installation of low carbon heating systems, including air source and ground source heat pumps. With grants available to offset upfront costs, BUS helps homeowners and landlords move away from fossil fuel heating. This is particularly relevant as gas boilers are gradually phased out in favour of renewable alternatives. While the funding opportunities are substantial, navigating the application and compliance process can be complex. Each scheme has strict eligibility criteria, technical requirements, and reporting obligations. Councils and housing associations need experienced partners to prepare bids, manage compliance, and deliver works to PAS 2030 and PAS 2035 standards. TF Energy has extensive experience supporting clients through these processes. We provide accurate surveys, detailed programme planning, and full documentation to ensure applications are successful and funding is secured. Our proven track record with local authorities such as Camden, Newport, and Bristol shows how structured delivery and compliance-focused project management make the difference between approval and rejection. The £6 billion pipeline represents a once-in-a-generation opportunity to transform housing stock and improve living conditions. With the right support, landlords and councils can unlock funding, deliver compliant projects, and create warmer, greener, and more affordable homes for their residents. TF Energy stands ready to guide clients through every step of the process.

Successful retrofit programmes rely not only on technical delivery but also on how well residents are supported throughout the process. For councils and contractors, managing expectations and minimising disruption are as important as meeting compliance standards. TF Energy’s experience across large scale housing upgrades highlights the value of a structured, resident focused approach. Preparation begins before a single tool arrives on site. Residents need clear information about what will happen, when, and how it will affect them. Providing easy to understand guides, holding pre start meetings, and offering direct points of contact reduces anxiety and builds trust. For many households, retrofit works represent a major upheaval, so reassurance and transparency are essential. One best practice is to agree practical arrangements in advance. This can include setting up zones for tools and materials, identifying safe spaces for storing possessions, and clarifying access requirements. By involving residents in these decisions, contractors avoid misunderstandings and create a sense of partnership rather than intrusion. Communication must continue throughout the programme. Regular updates, check ins, and feedback opportunities help residents feel listened to and respected. Simple steps, such as explaining daily work schedules or providing notice of noisy activities, go a long way towards maintaining goodwill. TF Energy ensures site teams follow a clear code of conduct so that professionalism is upheld at every stage. Contractors also need to consider vulnerable residents. Older tenants, families with young children, or those with health conditions may need extra support. This might involve scheduling works around medication times, ensuring heating and hot water are restored quickly, or arranging temporary accommodation if major disruption is unavoidable. Councils benefit from having a partner who anticipates these needs and provides tailored solutions. Another vital aspect is managing the resident handover once works are complete. Demonstrating new systems, explaining maintenance requirements, and providing written instructions ensure residents can fully benefit from the upgrades. For example, after an air source heat pump installation, clear training on controls helps households save energy and lower bills. When residents feel informed, respected, and supported, retrofit projects run smoother and with fewer delays. Councils can meet compliance targets while maintaining positive community relationships, and contractors can deliver works without avoidable setbacks. TF Energy’s structured resident engagement process has proven successful across projects in Camden, Newport, and Bristol, offering a model for others to follow. Retrofit is about more than buildings. It is about people, and preparing residents properly ensures that sustainability targets are achieved while communities remain at the heart of the journey.

Across the UK, councils are under pressure to upgrade their housing stock in line with government targets. Meeting EPC requirements, improving living standards, and cutting energy costs all depend on effective retrofit delivery. TF Energy has worked with local authorities including Camden, Newport, and Bristol, providing valuable insight into how large-scale programmes can succeed when managed correctly. One of the biggest challenges on any housing project is resident engagement. Homes are not empty shells, they are lived in by families, older residents, and vulnerable tenants who all have different needs. Work must be carried out while minimising stress and disruption. TF Energy addresses this by preparing residents before projects begin. Information packs, prestart meetings, and clear communication channels ensure people know what to expect. From setting up designated tool zones to arranging safe storage of possessions, these steps build trust and reduce conflict once work is underway. Sequencing the works is another area that requires experience and careful planning. Retrofit programmes often involve multiple trades, from insulation and heating engineers to scaffolders and renewable specialists. Without clear coordination, delays and clashes are inevitable. TF Energy has developed a structured process for sequencing, allowing different phases to flow smoothly. This approach shortens programme timelines, reduces costs, and ensures projects remain compliant with PAS 2030 and PAS 2035 standards. Compliance is non-negotiable. Councils and housing associations must be able to evidence that installations meet strict quality and safety regulations. TF Energy supports this by embedding robust record keeping into every stage of delivery. Digital monitoring, site inspections, and a strong installer code of conduct provide the “golden thread” of accountability that regulators and council’s demand. The recent Camden projects highlighted the importance of balancing technical upgrades with resident wellbeing. For example, during insulation works in high density housing blocks, clear scheduling and resident liaison meant works were completed without long term disruption to tenants. In Newport, where heat pump pilots were introduced to schools and homes, the lessons learned were used to refine methods before rolling them out more widely. Bristol projects reinforced the value of early survey accuracy, as identifying property specific issues in advance avoided costly changes later. Large scale retrofit is complex, but it is achievable when supported by the right partner. TF Energy’s experience shows that combining resident care, precise sequencing, and strict compliance results in programmes that deliver real improvements for councils and communities. These lessons will shape future housing upgrades and help local authorities meet their ambitious sustainability goals.

The government has set ambitious energy performance targets that will reshape the housing and property sector over the next decade. By 2027, all rental properties must reach an EPC rating of C, with a further requirement for an EPC rating of B by 2030. These deadlines apply to both social housing providers and private commercial landlords, and the consequences for failing to meet them are serious. Properties that do not comply will face penalties, risk becoming unrentable, and may lose long term value. For local authorities, the challenge is twofold. They must upgrade their own housing stock while also ensuring private landlords comply with the regulations. Councils are being asked to balance limited budgets, government targets, and the practical realities of improving older homes that often have structural and design challenges. Housing associations and local authority landlords face additional pressure because their properties must remain safe, habitable, and affordable for residents during the retrofit process. Commercial landlords face a different but equally demanding situation. Many office blocks, retail units, and mixed-use developments still fall below the required standard. Upgrading these buildings will often involve major fabric improvements, renewable energy installations, and modern heating systems. The cost of non-compliance could result in vacant buildings, reputational damage, and lost rental income. TF Energy is actively supporting clients to prepare for these changes. With experience delivering retrofit programmes across London, Bristol, Newport, Hampshire, and many other regions, TF Energy understands the complexity of managing large scale projects. Our teams help structure and phase works so that disruption is minimised, and residents remain fully informed. By applying tried and tested processes, we ensure programmes are completed on time and in line with PAS 2030 and PAS 2035 standards. Preparation is key. A strategic approach, starting with accurate surveys and clear planning, ensures landlords and councils can meet the targets without last minute rushes or unnecessary costs. TF Energy provides end to end support, from detailed property assessments to installation and final compliance checks. Our project management expertise allows us to deliver on housing stock upgrades, civic buildings, schools, and commercial portfolios. The 2027 and 2030 EPC requirements are not optional. They are part of the UK’s wider commitment to net zero, lower energy consumption, and improved living standards. Landlords and local authorities who act now will be better placed to meet deadlines, protect asset value, and contribute to a more sustainable built environment. TF Energy stands ready to help clients navigate this critical transition.

Commercial property owners are facing the prospect of tougher efficiency rules in the coming decade. Evidence is building that Minimum Energy Efficiency Standards (MEES) will rise significantly. The current threshold for many properties is EPC E, but proposals suggest this could be lifted to EPC B by the mid-2030s. If adopted, this would represent one of the biggest regulatory shifts for the commercial real estate sector in years. Properties that fall short would be unable to be leased, creating major financial risk for landlords and investors. For those managing large portfolios of offices, warehouses, and retail spaces, the potential scale of upgrade work is vast. The challenge is that many commercial buildings were not designed with efficiency in mind. Older stock in particular is difficult to retrofit, with poor insulation, outdated heating systems, and limited space for renewable technologies. Bringing these properties up to EPC B will require more than basic improvements. Whole-building strategies will be needed, combining fabric upgrades such as insulation, glazing, and ventilation with renewable systems like heat pumps, solar PV, and battery storage. Standard trades including heating, plumbing, and electrical works will also form part of the solution. For landlords, the key issue is cost and planning. Retrofitting at scale requires careful sequencing, strong supply chain partnerships, and a clear understanding of compliance requirements. Those who wait until regulation is enforced risk higher costs, contractor shortages, and long periods where assets cannot be legally let. TF Energy is ready to support clients through this transition. Our approach combines compliance expertise with practical delivery. We manage the documentation and standards while providing hands-on installation across all measures, from insulation and renewables to mechanical and electrical upgrades. By planning now, commercial landlords can spread costs, protect asset value, and avoid being caught out by future deadlines. The direction of travel is clear. Minimum Energy Efficiency Standards will only tighten, and the timeline is already being discussed. For landlords who act early, the opportunity is not just about compliance but also about reducing running costs, attracting tenants, and strengthening long-term investment performance.

The UK government is consulting on new rules that could significantly raise the standards for socially rented homes in England. The consultation, running from July to September 2025, proposes setting a minimum EPC requirement for properties managed by local authorities and housing associations. The target under discussion is moving towards EPC C by 2030 , bringing social housing in line with the wider push for higher efficiency across the property sector.  Currently, many socially rented homes have very low EPC ratings. This not only leads to higher energy bills for tenants but also contributes to fuel poverty and poor living conditions. The proposed changes aim to tackle these issues head-on by ensuring homes are warmer, more efficient, and cheaper to run. For local authorities, this would mean legally binding obligations to upgrade their housing stock over the next five years. The scale of the challenge is significant. Social landlords manage millions of properties, many of which are older and harder to retrofit. Meeting EPC C will require widespread fabric upgrades such as insulation, ventilation, windows and doors, along with renewable technologies including heat pumps and solar PV. Standard trades such as heating, plumbing, electrical, and building works will also play a key role in achieving compliance. While the consultation signals strong intent from government, it also raises concerns for housing providers already struggling with budget pressures and resource constraints. Funding routes exist, but accessing and managing them can be complex. The risk is that without the right expertise, projects stall or fail to deliver the required outcomes. TF Energy is well-placed to support this transition. Our teams specialise in large-scale retrofit projects, combining compliance expertise with hands-on delivery. We help councils and housing associations navigate documentation, design effective upgrade programmes, and carry out the installations needed to raise EPC ratings. With experience across fabric, renewable, and traditional trades, we provide complete solutions that deliver measurable improvements for residents while keeping organisations on track with government targets. If the proposals are adopted, the clock will be ticking for social landlords. Acting early will reduce costs, secure reliable partners, and ensure housing stock is improved in a way that benefits both tenants and communities.

Across the UK, a shift is taking place in how people view energy efficiency. For years, the market has been flooded with smart gadgets promising to save money and cut carbon. From Wi-Fi controlled plugs to app-based heating add-ons, homeowners and businesses were encouraged to believe technology alone could transform energy use. Now, the reality is setting in. Many of these products deliver little more than novelty, with users admitting they see no meaningful reduction in their bills. Recent surveys show growing regret among households and businesses that invested in flashy tech without addressing the fundamentals. The lesson is clear. Energy efficiency must be built on measures that deliver measurable impact, not gimmicks that look good but change little. The real value lies in proven improvements. Fabric upgrades such as insulation, double glazing, and controlled ventilation reduce heat loss at source. Heating system upgrades, from efficient boilers to modern heat pumps, cut ongoing consumption. Renewable technologies such as solar PV and battery storage allow clients to generate and use more of their own energy. Each of these measures provides tangible benefits in the form of lower bills, higher EPC ratings, and improved comfort. For landlords and commercial property owners, focusing on these no-nonsense improvements is also the only way to remain compliant with upcoming regulations. By 2027, rented properties must reach EPC C, rising to EPC B by 2030. Smart gadgets alone cannot bridge that gap. Whole-building solutions are required, integrating both traditional trades and new technologies in a way that makes properties future-proof. At TF Energy, we focus on what works. Our role is to cut through the noise of the latest fads and help clients invest where it matters most. We combine fabric improvements, renewable systems, and standard trades into tailored packages that achieve compliance, reduce costs, and deliver long-term value. In a time when energy prices remain volatile and regulatory deadlines are approaching fast, clients are looking for results they can see and measure. Real efficiency, not gimmicks, is what makes the difference.

The government has set ambitious targets for energy efficiency, but for many property owners the gap between regulation and reality is widening. By 2027, all rented properties must achieve EPC C. By 2030, the requirement increases to EPC B. These deadlines are fast approaching, and the cost of failing to comply is significant. Properties that do not meet the standard will not only face penalties but could become legally unlettable.  The challenge is scale. Commercial landlords and portfolio owners are looking at entire building stocks that need urgent upgrades. Many older properties were built with little thought for insulation, ventilation, or renewable technology. Retrofitting them to modern standards is not a simple task. It requires careful planning, major investment, and access to a skilled supply chain that is already under strain. For many owners, the biggest concern is feasibility. The cost of whole-building upgrades can be daunting, particularly when factored across large portfolios. Add to that the uncertainty around government guidance and the limited availability of trusted installers, and it is clear why so many property managers feel exposed. Waiting until the last minute is a high-risk strategy, but many are unsure how to move forward. The practical reality is that no single measure will deliver compliance. Most buildings require a package of improvements, from fabric upgrades such as insulation, glazing, and ventilation, through to renewable technologies like heat pumps, solar PV, and battery storage. Sequencing these works properly is just as important as the measures themselves, as poor planning can lead to wasted investment or failed compliance checks. TF Energy bridges this gap between ambition and delivery. Our role is to manage the compliance process, handle the documentation, and deliver the practical works on site. We cover everything from assessments and design through to full installation, including standard trades such as heating, plumbing, electrical, and building works. By combining technical expertise with hands-on delivery, we help clients meet regulatory demands without unnecessary cost or disruption. The regulations are not going away. Owners who act now will spread costs, secure reliable contractors, and protect the value of their assets. Those who delay risk being left behind with properties that are both non-compliant and unlettable.

The UK is investing heavily in social housing upgrades, with billions now being directed towards energy efficiency. These programmes are designed to cut bills for low-income households, reduce carbon emissions, and help meet national climate targets. For councils and housing providers, this funding represents both an opportunity and a challenge. Earlier this year, the government announced a £1.8 billion investment into home energy-saving upgrades. The funding is focused on practical improvements such as insulation, ventilation, heat pumps, and solar panels. These are the measures that deliver immediate results by reducing energy consumption, lowering household costs, and improving comfort for residents. Alongside this, the National Wealth Fund has stepped in with £250 million in guaranteed loans to support social housing retrofit projects. Combined with other financial support, this brings the total package close to £1 billion in additional backing for housing providers. The intention is clear: push local authorities and registered social landlords to accelerate retrofit delivery across their housing stock. While the money is welcome, accessing and using it effectively is not straightforward. Funding often comes with complex criteria, strict reporting requirements, and tight deadlines. Many councils and housing associations struggle with the administrative side of these schemes, leading to delays or missed opportunities. The reality is that technical knowledge, project management, and compliance expertise are just as important as the funding itself. This is where TF Energy provides real value. We support local authorities and housing providers by focusing on the delivery phase. Our teams specialise in whole-building retrofits, covering fabric upgrades such as insulation, windows and doors, along with renewable technologies including air source heat pumps, solar PV, and battery storage. We also manage the standard trades such as heating, plumbing, electrical, and building works, ensuring every project is completed to PAS-accredited standards. By working with TF Energy, clients gain a trusted partner who understands both the compliance landscape and the practical realities of installation. The result is projects that deliver measurable improvements for residents, meet government targets, and make best use of available funding.  The government’s message is clear. Social housing providers are expected to act now and improve the performance of their stock. With the right partner, these projects can transform homes, reduce bills, and leave a lasting positive impact on communities.
