Retrofit Assessment in London — PAS 2035
A PAS 2035 Retrofit Assessment for homeowners, landlords and grant-funded retrofit projects across Kensington and central London. Whole-house assessment, condition report and occupancy survey — flat fee of £250.
What the assessment covers
Whole-house survey
Measured survey of the building fabric, construction type, insulation, glazing, ventilation and heating systems.
Condition report
Identification of defects, damp, structural risks and ventilation issues that affect which retrofit measures are safe.
Occupancy assessment
How the household heats the home, uses hot water, and lives in the space — essential for accurate retrofit design.
RdSAP or SAP assessment
The energy calculation used to model the current performance and predict improvements from planned measures.
Who needs a Retrofit Assessment?
- Grant-funded retrofit schemes — ECO4, Great British Insulation Scheme and other PAS 2035-backed routes usually require an accredited assessment before work is approved.
- Homeowners planning deep retrofit — insulate walls, roofs, floors, upgrade heating or improve ventilation safely and in the right order.
- Landlords and agents — meet higher energy-efficiency standards and prepare properties for future Minimum Energy Efficiency Standards (MEES).
- Retrofit Coordinators and installers — we provide the assessment data required to feed into a whole-house retrofit plan.
Retrofit Assessment questions
- What is a PAS 2035 Retrofit Assessment?
- A PAS 2035 Retrofit Assessment is the first step of the whole-house retrofit process. It combines aRdSAP or SAP assessment, a detailed condition report, and an occupancy assessment so that retrofit measures can be designed safely and effectively.
- Who needs a Retrofit Assessment?
- Homeowners applying for government grants such as ECO4 or the Great British Insulation Scheme, landlords planning energy upgrades, and anyone working with a Retrofit Coordinator to design a whole-house improvement plan.
- What is included in the £250 assessment?
- A full measured survey of the property, aRdSAP/SAP energy assessment, a condition report identifying risks such as damp and ventilation, and an occupancy assessment covering how the household uses heating and hot water.
- How long does the survey take?
- Most residential Retrofit Assessments take around one to two hours on site, depending on the size and complexity of the property. The report is then processed off-site and returned to you promptly.
- Do you cover London and the surrounding areas?
- Yes — we are based on High Street Kensington, W8, and carry out Retrofit Assessments across Kensington, Chelsea, Notting Hill, Maida Vale, Hammersmith, Fulham and the wider central London area.
- Do I need a Retrofit Coordinator first?
- Not always. Some homeowners book the assessment directly to start their retrofit journey. If your grant scheme requires a Retrofit Coordinator, we can provide the assessment outputs they need in the PAS 2035 format.
