What is an EPC?

An Energy Performance Certificate (EPC) shows how energy efficient your property is by providing a rating from A (most efficient) to G (least efficient). This certificate also provides recommendations for improving the energy efficiency of the property, including identifying any possible cost-saving measures. The certificate will list all of the relevant details such as age, type of building, occupancy rate, size of windows, insulation levels etc., that affect its energy efficiency rating.

Why Do Homeowners and Landlords in Pontardawe Need One?

In order to comply with government regulations, all homeowners and landlords in Pontardawe are required to have an Energy Performance Certificate (EPC). This certificate must be obtained before being able to rent out their properties or sell them on the open market. It’s important that potential buyers or tenants can see the EPC rating before they make any decisions regarding renting or buying a property. It helps them decide whether the property meets their needs in terms of both cost savings and environmental impact.

Benefits of Having an EPC

Having an up-to-date Energy Performance Certificate can help homeowners reduce their carbon footprint while also saving money on energy bills – up to £320 a year according to some estimates! Furthermore, having an updated certificate can help increase the value of your property when it comes time to sell or rent out your home by demonstrating its energy efficiency rating to potential buyers and tenants. Finally, having an EPC can provide peace of mind knowing that you are complying with government regulations concerning energy efficiency standards in residential properties across Wales.

What Specific Things Does an Assessor Look For?

When an EPC assessor visits a property, they typically look at the following aspects:

  1. Building Construction and Materials: They will assess the age, material, and construction type of the property, as these factors can greatly affect its insulation properties and overall energy efficiency.
  2. Insulation: The assessor will check the loft, walls, and floors for insulation, which can help to reduce the amount of heat that escapes from a property. They will also look at the condition and type of insulation used.
  3. Heating System: The assessor will check the boiler or heating system, its efficiency rating, the controls it has (like thermostatic controls), and whether it’s an old or modern system. They will also look at whether the property has a hot water tank and whether it is insulated.
  4. Ventilation: They will check if the property is properly ventilated, as poor ventilation can lead to dampness and mould problems, which can affect the energy efficiency of the property.
  5. Windows and Doors: The assessor will check the windows and doors for double glazing and draught-proofing. They will also take into account the type and age of the windows.
  6. Lighting: The type of light bulbs used in the property (e.g., LED, CFL, incandescent) will be checked, as energy-efficient light bulbs can lower energy usage.
  7. Renewable Energy Sources: If the property uses renewable energy sources, such as solar panels or wind turbines, this will also be assessed and can positively impact the energy efficiency rating.

After collecting the necessary data, the EPC assessor will then input it into a software program which calculates the energy efficiency of the property and gives it a rating. The EPC will also include recommendations on how to improve the property’s energy efficiency.

EPC data for Pontardawe

Figures below are for Neath Port Talbot, the local authority covering Pontardawe, from the Energy Performance of Buildings Register to 2026 Q2.

2,177EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 39% of certificates
47%Rated D or below, against 46% nationally
£880Average 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 Neath Port Talbot rates

Share of the 15,257 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

77% of the certificates lodged here are for houses. The average floor area is 86.3m², about the England and Wales average. Estimated heating costs average £880 a year, £59 a year below the national figure. 30% of certificates were lodged for rented homes.

Radon in Pontardawe

Pontardawe 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 Pontardawe

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.

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.
