Before the funding flows, the house gets read.
Any publicly funded retrofit has to follow PAS 2035. That covers external wall insulation, loft top-ups, air source heat pumps and the rest. PAS 2035 starts with a Retrofit Assessment: one visit that captures the dwelling as it actually is, so the measures designed for it actually work.
What the assessment includes
- Condition survey: the fabric as found. Damp, ventilation, structural condition, existing insulation, and anything that would put measures at risk.
- Occupancy assessment: how the household actually uses the home. Heating patterns, hot water demand, comfort issues.
- Energy report: a full RdSAP assessment with floor plans, measurements and photographs.
The three together go to the Retrofit Coordinator, who uses them to design the improvement plan the funding pays for.
Who books us
- Installers and retrofit firms: assessments delivered fast enough to keep your pipeline moving across multiple properties.
- Retrofit Coordinators: clean, complete PAS 2035 submissions you don't have to chase.
- Householders and landlords: if you've been offered grant-funded work and been told you need an assessment first, that's us.
What happens on the day
Longer and deeper than an EPC visit. We survey every room and the loft, draw the floor plan, photograph the fabric, record ventilation provision, and note condition issues like damp or failed pointing that a retrofit design must deal with rather than bury. Old Wealden housing (solid walls, timber frames, suspended floors) is exactly where careless retrofit goes wrong, and exactly why the standard exists.
After the visit
The full assessment is written up and submitted to your Retrofit Coordinator or scheme contact, with floor plans and photo evidence attached. Turnaround depends on scheme paperwork, but the survey data leaves us fast. Installers with deadlines should say so when booking and we'll work to them.
What we draw on site
Every assessment includes measured floor plans with wall build-ups, floor types, ventilation and condition notes. A retrofit designed from the wrong wall thickness or a forgotten airbrick is how insulation ends up causing damp instead of curing it.
The plan, photographs and RdSAP data go to your Retrofit Coordinator as one PAS 2035 submission.
Straight answers
Do I need a Retrofit Assessment before grant-funded work?
Yes. Any publicly funded retrofit has to follow PAS 2035, and PAS 2035 starts with a Retrofit Assessment. If you've been offered work under ECO4, the Great British Insulation Scheme or another TrustMark route and told you need an assessment first, this is what they mean.
What does the assessment actually include?
Three things from one visit: a condition survey of the fabric as found, an occupancy assessment of how the household uses the home, and an energy report (a full RdSAP assessment with floor plans, measurements and photographs). All three go to your Retrofit Coordinator, who designs the improvement plan the funding pays for.
How long does it take, and when does it reach the coordinator?
The visit is longer and deeper than an EPC visit: every room and the loft, the floor plan drawn, the fabric photographed, ventilation and condition recorded. Afterwards the full assessment is written up and submitted to your Retrofit Coordinator or scheme contact. Turnaround depends on scheme paperwork, but the survey data leaves us fast. Installers with deadlines should say so when booking and we'll work to them.
