Local EPC assessors
Energy Performance Certificates for every Windsor property.
Windsor's housing is unusually varied for its size — Georgian and Victorian townhouses in the centre and around Eton, listed and conservation-area properties near the Castle and Park, solid inter-war family homes in Clewer and Dedworth, and riverside apartments towards Datchet and Old Windsor. Period, listed and solid-wall properties need careful, evidence-based assessment so the rating reflects the building fairly.
Our Domestic Energy Assessors are fully qualified, ECMK registered and Quidos accredited, with more than 15,000 homes assessed. We measure the property, record the construction, insulation, glazing, heating and controls, then lodge your certificate on the national EPC register. Reports are usually issued within 24 hours after the property survey, subject to receiving all required information.
An EPC is valid for 10 years and is a legal requirement whenever a property in Windsor is marketed for sale or let. We work closely with Windsor estate agents who need the certificate and a measured floor plan captured together so the listing can go live quickly.

Windsor EPC questions.
How quickly can you carry out an EPC in Windsor?
In most cases we can attend a Windsor property the same day or next day, and reports are usually issued within 24 hours after the property survey, subject to receiving all required information.
How much does an EPC cost in Windsor?
£80 for an EPC, £130 for an EPC and floor plan together, and £80 for a floor plan on its own. Commercial EPCs start from £150 — no hidden travel charges within Windsor and the surrounding SL4 postcodes.
How long does the survey take?
A typical Windsor house or flat takes 30–45 minutes. We need access to every room, the loft hatch, the boiler and the meters.
Can you assess listed and period properties in Windsor?
Yes. Many Windsor and Eton homes sit in conservation areas or are listed. We survey them in line with RdSAP conventions and record solid-wall construction, secondary glazing and original features properly — and we'll explain where a listing restricts the improvements the report can recommend.
