Domestic & Commercial Energy Performance Certificates (EPC) Colchester
We provide EPCs in Colchester and across Essex for both Domestic and Commercial properties. A valid EPC is required to be in place before the sale or rental of your property. The EPC survey itself is entirely non intrusive and won't damage the building in any way. Once the survey is complete the EPC report will be produced, which gives the building an Energy Performance Rating rating on a scale from A to G.
For most rental properties an EPC rating of E or better is required, in compliance with the Minimum Energy Efficiency (MEES) legislations of 2018. For properties for sale, MEES legislation does not yet apply, however an ever increasing number of financial institutions require properties to demonstrate they would be MEES compliant before agreeing mortgage funding.
Across Colchester, the most common domestic EPC band is C, with 60% of homes rated C or above and an average energy-efficiency score of 70 out of 100. Commercial properties in the wider Colchester area have an average rating of C 65 (UK average D 77).
There is real room to improve: the average Colchester home could raise its score by about 14 points, and 63% could improve by 10 points or more. The average home here emits roughly 3.2 tonnes of CO₂ a year.
Around 57% of homes in Colchester are owner-occupied and 26% are privately rented. About 63% are houses and 24% flats, and 77% are heated by mains gas. On the fabric, 80% have insulated cavity walls and 91% are fully double-glazed or better.
Letting a property in Colchester? About 47% of privately rented homes here are rated below an EPC C, the level the government has proposed as a future minimum for rented homes, and 0.8% are rated F or G, below the EPC E minimum needed to let a home today. We can carry out the EPC and advise on the most cost-effective way to improve the rating.
New-build makes up about 17% of certificates in Colchester, averaging a band B. New builds need a SAP calculation and an as-built EPC, both of which we provide.
These figures are from analysis of the 53,992 currently valid domestic EPCs for Colchester in the publicly available government data set, covering certificates lodged in the ten years to 2026-08-16 (one per property, its latest). Values are medians/averages from the source data.
