EPC Balham

Need an EPC in Balham? Contact a local accredited energy assessor directly to check availability, confirm the price and arrange a time that works for you.

An Energy Performance Certificate rates how energy efficient a property is on a scale from A to G. In most cases a valid EPC must be in place before a home is marketed to sell or let.

Balham is a well-connected residential district of south London within the borough of Wandsworth. Its housing is dominated by Victorian and Edwardian terraces, many of them converted into flats, alongside mansion blocks and purpose-built apartments and a scattering of newer developments. EPC assessments in Balham are frequently arranged for period terraced houses, flat conversions, mansion-block apartments and modern flats.

Local EPC assessments in Balham

Balham’s housing is heavily weighted towards period property, so the assessment often reflects the features of older homes. Victorian and Edwardian houses and conversions commonly have solid walls, original sash windows and heating that has been added over time, all of which influence the rating. Purpose-built and newer flats built to modern insulation standards tend to perform differently. The assessor records the details of each individual property rather than assuming a band from the age of the street.

EPCs for Balham flats, apartments and rental properties

Balham has a large and active rental market, supported by its strong transport links into central London. Rental homes here range from converted flats in period houses to mansion-block and purpose-built apartments and larger family lets. Converted properties can have less predictable construction, heating and glazing, so the certificate needs to reflect each individual home. If you already hold an EPC, you can check whether it is still valid on the government EPC register before arranging a new one.

What happens during an EPC assessment?

A domestic EPC assessment is usually straightforward. The assessor visits and records details such as:

  • the size and layout of the property
  • its age and construction type
  • the heating system and controls
  • insulation
  • windows and glazing
  • lighting
  • any relevant renewable technologies
  • energy efficiency upgrades and paperwork

These findings produce the rating and recommendation report. Flat conversions and homes with unusual layouts can take a little longer, so mention anything unusual when you book.

How quickly can I book an EPC in Balham?

Many people searching for an EPC in Balham already have a sale, tenancy or listing moving forward, and an agent has often asked for the certificate before marketing begins. Booking early helps avoid delays, especially in a market with so many converted and period properties.

EPCs for Balham landlords

Landlords need a valid EPC before letting a property in Balham, and the certificate helps confirm whether the home meets the current Minimum Energy Efficiency Standards. With much of the local rental stock made up of period conversions, the recommendation report can be a useful guide to worthwhile improvements.

EPCs for homeowners selling a property

Selling a house or flat in Balham usually means having an EPC ready before it is listed, whether it is a period terrace or a modern apartment. Arranging it early is one less thing to handle during the sale, and the recommendation report can flag improvements worth considering.

EPC data for Balham

Figures below are for Lambeth, the local authority covering Balham, 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 Balham

Balham 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 Balham centre show 26 conservation areas, 178 listed buildings and 49 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 Balham

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.
