EPC Barry – Energy Performance Certificates

If you’re selling or letting a property in Barry, you’ll need a valid Energy Performance Certificate (EPC) before it can be marketed. An EPC shows how energy-efficient a property is and provides a rating from A (most efficient) to G (least efficient).

This page helps you arrange a local EPC in Barry quickly and efficiently, whether you’re a homeowner, landlord, or preparing a property for sale or rent.

Local EPCs for Barry properties

Barry has a varied housing stock, and EPCs are commonly required for properties in areas such as:

  • Barry Island and central Barry – older terraced housing and period properties, often with solid walls and traditional construction

  • Cadoxton – a mix of terraces and post-war housing where insulation levels can vary

  • Gibbonsdown – predominantly post-war estates, where EPC ratings can differ significantly depending on upgrades

Because EPC results are influenced by construction age, insulation, and heating systems, properties across Barry can produce very different ratings even within the same town.

What happens during an EPC assessment?

During an EPC assessment in Barry, the assessor will typically review:

  • Property size, layout, and age

  • Wall construction and insulation (where visible)

  • Loft or roof insulation (if accessible)

  • Heating system, controls, and hot water provision

  • Windows, glazing, and fixed lighting

The assessment is non-invasive and usually takes 30–60 minutes, depending on the property.

How quickly can I get an EPC in Barry?

In most cases:

  • Appointments are available within a few days

  • The on-site assessment is completed in under an hour

  • The EPC is lodged on the national register within 24 hours of the visit

This allows sellers and landlords to move forward without unnecessary delays.

EPC data for Barry

Figures below are for Vale of Glamorgan, the local authority covering Barry, from the Energy Performance of Buildings Register to 2026 Q2.

2,455EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 51% of certificates
43%Rated D or below, against 46% nationally
£1,024Average 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 Vale of Glamorgan rates

Share of the 14,805 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

69% of the certificates lodged here are for houses. The average floor area is 96.1m², roughly 11m² larger than the England and Wales average. Estimated heating costs average £1,024 a year, £85 a year above the national figure. 39% of certificates were lodged for rented homes.

Radon in Barry

Barry 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 Barry

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.
