EPC Corsham

Looking for an EPC in Corsham? Get in touch with a local accredited energy assessor to check when they are free, confirm the cost and arrange a visit.

An Energy Performance Certificate rates a property's energy efficiency on a scale from A at the top to G at the bottom. A valid EPC is normally required before a house or flat is put up for sale or let.

Homes in Corsham range from older terraced and period properties through to more recent developments, so EPCs are needed for a wide mix of house types — terraces, semi-detached and detached houses, converted flats and newer builds.

Inside the EPC assessment

During the visit the assessor inspects the property and records details that affect its energy performance, including:

  • the size and layout of the home
  • property age and construction type
  • the heating system and its controls
  • insulation
  • any renewable technologies such as solar panels
  • windows and glazing
  • lighting
  • energy efficiency upgrades and paperwork

From this the assessor works out the EPC band and prepares a report of recommendations. Larger or converted properties may take a little more time, so it is worth flagging anything unusual when arranging the visit.

How quickly can I book an EPC in Corsham?

Most EPC requests in Corsham come with a deadline — a property going on the market, a tenancy starting or an agent requesting the certificate before listing. Arranging the assessment early keeps things moving and makes scheduling easier, particularly for larger or more complex homes.

Landlords in Corsham

Rental homes in Corsham need a valid EPC before they are marketed, and the certificate is the starting point for meeting the landlord MEES requirements. Beyond compliance, it flags the improvements most likely to raise the property's efficiency.

EPCs for homeowners selling a property

If you are selling a house or flat in Corsham, you will usually need an EPC before marketing begins — whatever the property type. Arranging it early is one less thing to deal with once the sale is under way, and the recommendation report can flag quick improvements that may help the rating.

EPC data for Corsham

Figures below are for Wiltshire, the local authority covering Corsham, from the Energy Performance of Buildings Register to 2026 Q2.

7,902EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 45% of certificates
51%Rated D or below, against 46% nationally
£1,077Average estimated heating cost a year

That expiry count is certificates lodged ten years ago and now coming up for renewal. Some of those homes have already been re-certified since, which authority-level data cannot show, so treat it as the ceiling rather than a to-do list.

How Wiltshire rates

Share of the 62,985 certificates lodged in the five years to 2026 Q2. This is the certificates lodged, not a survey of every home in the area.

What gets assessed around here

68% of the certificates lodged here are for houses. The average floor area is 95.5m², roughly 10m² larger than the England and Wales average. Estimated heating costs average £1,077 a year, £138 a year above the national figure. 34% of certificates were lodged for rented homes.

Radon in Corsham

Corsham sits in the lowest radon band. The UKHSA and British Geological Survey estimate that less than 1 in 100 homes in the 1km square covering the town centre reach the radon action level of 200 becquerels per cubic metre. Radon is not part of an EPC survey and does not affect the rating. At this level it is not usually a concern, though individual homes can still vary. The atlas is indicative and works to a 1km grid, so it describes the area rather than any one property.

Listed buildings and conservation areas

Planning records published for the area within a mile of Corsham centre show 3 conservation areas and 1 article 4 direction area. That matters for an EPC in two ways. A listed building is normally exempt from needing one where meeting the minimum energy requirements would unacceptably alter its character or appearance, though the exemption is not automatic and the decision rests with the owner on advice. And in conservation areas and article 4 areas the improvements an EPC recommends, replacement glazing or external wall insulation in particular, often need consent before they can be carried out. Your assessor will record what is actually there; the consent question is one for the council.

What an EPC costs in Corsham

An EPC around here generally costs between £65 and £160, though it depends on the property: floor area, whether there are rooms in the roof, extensions, and how far the assessor travels all move the price. We are not a panel and we do not set anybody's fees, so the figure you are quoted comes from the assessor doing the work. Contact one above for a price on your property.
