EPC Trowbridge

Looking for an EPC in Trowbridge? 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 (EPC) shows how energy efficient a property is and gives it a rating from A (most efficient) to G (least efficient). You will usually need a valid EPC before a home is marketed for sale or rent.

Like most parts of the country, Trowbridge 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.

How an EPC assessment works

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
  • lighting
  • any renewable technologies such as solar panels
  • energy efficiency upgrades and paperwork

The assessor then uses this information to calculate the rating and produce a recommendation report. Older or unusually laid-out homes can take a little longer, so it helps to mention any unusual features when you book.

Booking an EPC in Trowbridge

Most EPC requests in Trowbridge 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 Trowbridge

Landlords need a valid EPC before marketing a rental property in Trowbridge. The certificate also helps show whether the property meets the Minimum Energy Efficiency Standards (MEES). In practice the EPC is more than paperwork — it can highlight insulation, glazing or heating improvements worth considering before the property is let.

EPCs for homeowners selling a property

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

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

Trowbridge 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 1 and 3 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.

Listed buildings and conservation areas

Planning records published for the area within a mile of Trowbridge centre show 3 conservation areas. 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 Trowbridge

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.

What to expect when a Domestic Energy Assessor comes to your property

Every Domestic Energy Assessor / DEA will have their own order and format of carrying out the EPC depending on the software that they use and their personal preference to efficiency.
