EPC Chepstow

Booking an EPC in Chepstow is straightforward — speak to a local accredited energy assessor to check their availability, agree a price and arrange the assessment.

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.

Property in Chepstow spans older period homes, mid-century housing and newer estates. An EPC may be needed for any of them, whether it is a terrace, a semi-detached or detached house, a converted flat or a modern build.

What happens during the 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
  • windows and glazing
  • any renewable technologies such as solar panels
  • 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.

Booking an EPC in Chepstow

Many people looking for an EPC in Chepstow already have a sale, letting or listing under way. An estate agent may have asked for the certificate before marketing begins, or a landlord may need one before advertising a rental. Booking early helps avoid delays and gives the assessor more flexibility with older or larger properties.

EPCs for rental properties in Chepstow

If you let property in Chepstow, 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

Homeowners selling in Chepstow normally need a valid EPC in place before the property is advertised. Sorting it out early keeps the sale on track, and the report's suggested improvements can highlight simple changes that may lift the score.

EPC data for Chepstow

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

1,468EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 47% of certificates
45%Rated D or below, against 46% nationally
£1,195Average 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 Monmouthshire rates

Share of the 9,716 certificates lodged in the five years to 2026 Q2. This is the certificates lodged, not a survey of every home in the area.

72% of the certificates lodged here are for houses. The average floor area is 103.7m², roughly 19m² larger than the England and Wales average. Estimated heating costs average £1,195 a year, £256 a year above the national figure. 27% of certificates were lodged for rented homes.

Radon in Chepstow

Chepstow sits in a radon Affected Area. The UKHSA and British Geological Survey put the 1km square covering the town centre in a band where between 10 and 30 in 100 homes are estimated to be at or above the radon action level of 200 becquerels per cubic metre. Radon is not measured during an EPC survey and does not affect the rating, but if you are buying, selling or improving a home here it is worth a test kit, and worth knowing before you seal a property up: draught-proofing and insulation work can raise indoor radon if ventilation is reduced. The atlas is indicative and works to a 1km grid, so it describes the area rather than any one property.

What an EPC costs in Chepstow

An EPC around here generally costs between £55 and £150, 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.
