EPC Melksham

Looking for an EPC in Melksham? 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.

Like most parts of the country, Melksham has a varied housing stock — a mix of older and character homes alongside more modern properties. EPCs are commonly required for terraced, semi-detached and detached houses as well as flats and recent developments.

What happens during the assessment

The assessment is a straightforward survey in which the assessor records the property's key characteristics, including:

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

This information feeds into the final rating and a list of recommended improvements. Period or non-standard homes can take slightly longer to assess, so let the assessor know about any quirks in advance.

How soon can I get an EPC in Melksham?

If you are selling or letting in Melksham, it is worth arranging the EPC as early as possible. Estate agents often ask for it before a property is advertised, and booking ahead reduces the risk of the certificate holding up a sale or tenancy.

EPCs for Melksham landlords

If you let property in Melksham, a valid EPC is required before the home is advertised, and it helps you check the property against the Minimum Energy Efficiency Standards. The recommendations can also point to practical upgrades — insulation, glazing or heating controls — that improve the rating.

EPCs for homeowners selling a property

If you are selling a house or flat in Melksham, 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 Melksham

Figures below are for Wiltshire, the local authority covering Melksham, 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 Melksham

Melksham 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 Melksham centre show 1 conservation 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 Melksham

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.
