Retrofit Services - RA, RD, RC
Upgrading the UK’s housing and building stock is essential to meeting national Net Zero targets, reducing energy bills, and improving comfort for residents.
Retrofit is the process of upgrading existing properties with energy-efficiency measures such as insulation, ventilation, heating, and renewable technologies.
At TF Energy we specialise in providing fully compliant retrofit services under PAS 2030 and PAS 2035. These frameworks set out strict requirements for how retrofit projects must be assessed, coordinated, designed, and delivered to ensure safe, effective, and long-lasting improvements.
Retrofit is not just a technical requirement, it’s a national priority. With millions of homes below EPC rating C and government funding streams such as SHDF and ECO+ driving mass upgrade programmes, professional retrofit services are essential to ensure compliance, quality, and resident protection.

Why Retrofit Is Required
- The UK has some of the oldest and least efficient housing stock in Europe.
- Poor energy efficiency contributes to higher bills, fuel poverty, and carbon emissions.
- Retrofit ensures properties are upgraded responsibly, with a whole-house approach that avoids issues such as damp, mould, or ventilation problems.
- PAS 2035 makes retrofit assessment, coordination, and design mandatory for publicly funded projects.
Retrofit Assessment
A retrofit assessment is the first step in identifying the right energy-efficiency measures for a property. It involves a detailed survey of the building’s construction, energy performance, occupancy patterns, and condition. This provides the evidence base for decision-making and ensures recommendations are tailored, accurate, and compliant.
Key outcomes:
- A full picture of the property’s current energy performance.
- Identification of risks and constraints.
- Data to inform retrofit coordination and design.
Retrofit Coordination
Retrofit coordination is the process of overseeing the whole retrofit project from start to finish. The Retrofit Coordinator is responsible for managing risks, ensuring PAS 2035 compliance, protecting the interests of the building owner and occupants, and making sure all measures are designed and installed correctly.
Key outcomes:
- Full compliance with PAS 2035 and funding requirements.
- A structured plan for safe and effective upgrades.
- Quality assurance and risk management throughout the project.
Retrofit Design 
Retrofit design turns the assessment findings into a practical plan for upgrading the property. Designs are created by competent professionals who ensure that proposed measures work together as part of a whole-building approach. This avoids unintended consequences and maximises energy savings.
Key outcomes:
- Accurate, tailored designs for each property.
- Integration of insulation, ventilation, and renewable systems.
- Long-term performance and reduced energy demand.
