EPC Central London

Need an EPC in Central London? Contact a local accredited energy assessor directly to check availability, confirm the price and book an appointment.

An EPC records a property's energy efficiency and assigns a band from A to G, along with recommendations for improvement. One is normally needed before a home can be advertised for sale or rent.

Property in Central London spans older period homes, mid-century housing and newer estates. An EPC may be needed for any of them, whether it is a terrace, a semi-detached or detached house, a converted flat or a modern build.

What happens during the assessment

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

From this the assessor works out the EPC band and prepares a report of recommendations. Larger or converted properties may take a little more time, so it is worth flagging anything unusual when arranging the visit.

How soon can I get an EPC in Central London?

If you are selling or letting in Central London, it is worth arranging the EPC as early as possible. Estate agents often ask for it before a property is advertised, and booking ahead reduces the risk of the certificate holding up a sale or tenancy.

Landlords in Central London

If you let property in Central London, a valid EPC is required before the home is advertised, and it helps you check the property against the Minimum Energy Efficiency Standards. The recommendations can also point to practical upgrades — insulation, glazing or heating controls — that improve the rating.

EPCs for homeowners selling a property

Homeowners selling in Central London normally need a valid EPC in place before the property is advertised. Sorting it out early keeps the sale on track, and the report's suggested improvements can highlight simple changes that may lift the score.

EPC data for Central London

Figures below are for Westminster, the local authority covering Central London, from the Energy Performance of Buildings Register to 2026 Q2.

5,026EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 58% of certificates
34%Rated D or below, against 46% nationally
£729Average 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 Westminster rates

Share of the 45,214 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

91% of the certificates lodged here are for flats and maisonettes, where houses lead nationally. The average floor area is 83.2m², about the England and Wales average. Estimated heating costs average £729 a year, £210 a year below the national figure. 55% of certificates were lodged for rented homes, a notably high share, so Minimum Energy Efficiency Standards bite harder here.

Radon in Central London

Central London 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 Central London centre show 65 conservation areas, 2,556 listed buildings and 89 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 Central London

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.
