What is an Energy Performance Certificate (EPC)?

An Energy Performance Certificate (EPC) is a comprehensive report that assesses a property’s energy efficiency by utilising an A-G rating system. A-rated properties are incredibly energy-efficient, while G-rated properties may require substantial improvements to meet current standards. This certificate not only provides vital information about the property’s energy consumption but also includes recommendations for improvements to enhance energy efficiency and reduce overall carbon emissions. Obtaining an EPC is crucial for property owners who want to comply with recent government regulations and ensure their property remains attractive to potential tenants and buyers.

Why do Homeowners and Landlords in West Ham Need an EPC?

Aside from being a legal requirement, obtaining an EPC offers various benefits for homeowners and landlords in West Ham. Firstly, it enhances the attractiveness of your property to potential buyers and tenants. An energy-efficient home is often more appealing to environmentally conscious individuals who are looking to reduce their carbon footprint and save on utility bills. Additionally, improving your property’s energy efficiency can directly impact its market value, thus providing a strong incentive for homeowners and landlords to invest in eco-friendly upgrades and modifications.

Advantages of Having an EPC

An EPC provides numerous advantages for property owners. By obtaining an assessment of your property’s energy efficiency, you can identify areas for improvement and implement cost-effective measures that will not only increase your property’s rating but also reduce energy costs. Furthermore, an up-to-date EPC can serve as a valuable tool when negotiating with potential buyers or tenants, as it demonstrates a commitment to maintaining an energy-efficient property. Finally, compliance with EPC regulations will ensure you avoid hefty penalties that can be imposed by the government for non-compliance.

EPC Government regulations

The UK government requires homeowners and landlords to obtain a valid EPC as part of its efforts to reduce the country’s overall carbon emissions. Since April 2018, landlords have been required to ensure their properties have a minimum energy efficiency rating of ‘E’ before they can be rented out. This regulation applies to both new tenancies and renewals, with those failing to comply facing fines of up to £4,000. Furthermore, as of 2020, homeowners are required to obtain an EPC whenever they sell or rent out their property, with potential buyers or tenants having access to this document before making a decision.

DEA: Inspecting Wall Thickness

A Domestic Energy Assessor (DEA) must measure the wall thickness as part of the EPC assessment, and at least one wall from every construction type found on the property should be addressed. It is essential that the DEA can access and measure the walls with ease, as this can significantly impact the overall rating of the property’s energy efficiency. Ensuring a smooth process by providing easy access to all walls and necessary information during the DEA’s visit can help homeowners and landlords receive an accurate assessment and improve their property’s EPC rating.

Preparing Your Property for Assessment

Homeowners and landlords can take specific measures to ensure a smooth and efficient DEA visit. This includes unlocking all windows for easy access, moving ornaments or furniture that may obstruct or restrict access to certain walls, and repositioning any items that could cause difficulties in measuring the wall thickness. By taking these steps ahead of time, you can prevent any delays or inaccuracies in the assessment process.

Accessibility to Meters

For an accurate assessment, the DEA must also inspect the gas and electricity meters. Homeowners and landlords should ensure that a clear path is provided for meters located outside and that any obstacles, such as bins or recycling boxes, are removed. For meters located inside or in high areas that require a ladder, clear the space around the meter and remove any hung coats or items that could hinder access. By doing so, you are making it easier for the DEA to gather the necessary information and provide you with an accurate EPC rating.

You can also check the EPC Register to see the current rating and expiry date for a West Ham property.

EPC data for West Ham

Figures below are for Newham, the local authority covering West Ham, from the Energy Performance of Buildings Register to 2026 Q2.

5,793EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 51% of certificates
38%Rated D or below, against 46% nationally
£683Average 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 Newham rates

Share of the 44,735 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

61% of the certificates lodged here are for flats and maisonettes, where houses lead nationally. The average floor area is 73.2m², roughly 12m² smaller than the England and Wales average. Estimated heating costs average £683 a year, £256 a year below the national figure. 56% of certificates were lodged for rented homes, a notably high share, so Minimum Energy Efficiency Standards bite harder here.

Radon in West Ham

West Ham 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 West Ham centre show 5 conservation areas, 3 listed buildings and 1 article 4 direction 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 West Ham

An EPC around here generally costs between £90 and £195, 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.
