EPC Clapham – Energy Performance Certificates

If you’re selling or letting a property in Clapham, you’ll need a valid Energy Performance Certificate (EPC) before it can be marketed. An EPC provides an energy efficiency rating from A (most efficient) to G (least efficient) and includes recommendations for improving performance.

This page helps homeowners and landlords arrange a local EPC in Clapham quickly and efficiently, whether you’re preparing a property for sale, letting, or compliance.

Local EPCs for Clapham properties

Clapham has a varied mix of period conversions, family homes, and modern apartments. EPCs are commonly required for:

Victorian and Edwardian terraces (Clapham North, Clapham Old Town, Abbeville Village)
Often solid wall construction. Ratings can vary significantly depending on insulation upgrades, glazing, and boiler efficiency.

Converted flats and maisonettes
Energy performance may depend on roof insulation, heating system type, and whether improvements have been made during conversion.

Modern apartment developments
Generally built to higher insulation standards, though heating systems and ventilation can still influence the rating.

Because EPC results depend on construction age, insulation levels, heating systems, and glazing, properties across Clapham can produce very different ratings even within the same street.

What happens during an EPC assessment?

An EPC assessment in Clapham involves a short, non-invasive inspection to collect the information required for the certificate.

The assessor will typically review:

  • Property size and layout

  • Construction type and wall structure (where visible)

  • Loft or roof insulation (if accessible)

  • Heating system, boiler details, and controls

  • Hot water provision

  • Windows, glazing type, and fixed lighting

  • energy efficiency upgrades and paperwork

Most domestic assessments take 30–60 minutes, depending on property size and access arrangements.

Providing documentation for insulation, boiler upgrades, or glazing installations can help ensure the most accurate rating.

How quickly can I get an EPC in Clapham?

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, landlords, and agents to proceed without unnecessary delays.

EPCs for landlords and sellers in Clapham

You will need an EPC if you are:

  • Selling a house or flat in Clapham

  • Letting a residential property

  • Marketing a property through an estate or letting agent

Landlords must ensure their property meets Minimum Energy Efficiency Standards (MEES) before it can be legally let.

More information is available here: EPC requirements for landlords 

Given Clapham’s strong rental market, ensuring compliance before marketing is particularly important.

EPC data for Clapham

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

5,741EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 56% of certificates
39%Rated D or below, against 46% nationally
£669Average 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 Lambeth rates

Share of the 57,723 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

81% of the certificates lodged here are for flats and maisonettes, where houses lead nationally. The average floor area is 72.1m², roughly 13m² smaller than the England and Wales average. Estimated heating costs average £669 a year, £270 a year below the national figure. 59% of certificates were lodged for rented homes, a notably high share, so Minimum Energy Efficiency Standards bite harder here.

Radon in Clapham

Clapham sits in the lowest radon band. The UKHSA and British Geological Survey estimate that less than 1 in 100 homes in the 1km square covering the town centre reach the radon action level of 200 becquerels per cubic metre. Radon is not part of an EPC survey and does not affect the rating. At this level it is not usually a concern, though individual homes can still vary. 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 Clapham centre show 25 conservation areas, 165 listed buildings and 17 article 4 direction 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 Clapham

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.
