EPCs across South London — from £69

South London is the second area we work out from, so these postcodes get the same short travel and the same fixed price. Pick your area for what the local stock means for your rating, or book straight away.

The one thing that decides most South London ratings

Here the question is not when your home was built but how much of it actually touches the outside. So much of South London is converted flats and purpose-built blocks that exposure, not era, is usually the deciding factor. A middle-floor flat with heated homes above, below and on both sides loses heat through very little, and often rates a full band better than the top-floor flat in the same building, which carries the whole roof. Get that mapping wrong — a party wall recorded as an external one — and the certificate is simply incorrect. It is the most common reason a South London EPC has to be re-lodged.

Clapham

SW4

Clapham is Victorian terrace radiating off the Common, punctuated by purpose-built Edwardian mansion blocks along the north and south sides.

Kennington

SE11

Kennington is Georgian terrace to a degree that little else in South London matches — long, flat-fronted, tightly controlled streets, a large share of it on the Duchy of Cornwall estate and much of it in conservation area.

Herne Hill

SE24

Herne Hill is late-Victorian and Edwardian family housing, and noticeably larger than the terraces a mile north in Brixton.

Balham

SW12

Balham is later than the Victorian stock further north — largely Edwardian terrace, wider fronted and better proportioned, laid out in long uniform streets.

What is actually changing, and when

Two separate things are in motion. One is the minimum rating a landlord must hold. The other is what an EPC measures in the first place. They are often muddled together, so here they are apart.

Landlords

The minimum goes from E to C

E is the minimum for a domestic let in England and Wales today. The government confirmed in January 2026 that this rises to C — for new tenancies from 2028, and for all existing tenancies from 1 October 2030. A spending cap of £10,000 per property applies, and penalties for letting below the standard run to £30,000.

Landlords

A C reached before October 2029 stays valid

Certificates last ten years. A property that reaches C before 1 October 2029 is treated as compliant until that certificate expires, which is a real argument for finding out where you stand now rather than in 2029.

RdSAP 10 already changed the survey itself

The assessment method behind domestic EPCs was overhauled from mid-2025 — the biggest revision since EPCs began. It asks for more detail on wall construction and insulation, and every window now has to be measured individually rather than sampled. That is why a proper visit takes 30 to 45 minutes and why photographic evidence matters.

Everyone

The single A–G rating is being replaced

The single headline letter is being dropped in favour of four separate measures: fabric performance, heating system, energy cost and smart readiness. This was due in October 2026, but in March 2026 the government pushed the launch back to the second half of 2027, with a firm date to be agreed with industry. Reformed certificates keep the ten-year validity, and anything lodged now stays valid for its full ten years regardless.

Common questions

How long does the visit take, and do I need to be there?

Thirty to forty-five minutes for a typical home, longer for a large or heavily extended one. Someone over eighteen needs to let us in and give access to the loft, the boiler, the meters and every room — including any room in the roof.

When do I get the certificate?

Usually within 48 hours of the visit, lodged on the central government register and emailed to you. It is valid for ten years and accepted by solicitors, estate agents and lenders.

Do you charge more to travel to the outer areas?

No. Every area listed on this page is the same price — £69 for up to three bedrooms, £89 for four or five.

We cover East London too, at the same prices.
