EPC Southwark

Booking an EPC in Southwark is straightforward — speak to a local accredited energy assessor to check their availability, agree a price and arrange the assessment.

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 Southwark 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.

Inside the EPC 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.

Booking an EPC in Southwark

Most EPC requests in Southwark come with a deadline — a property going on the market, a tenancy starting or an agent requesting the certificate before listing. Arranging the assessment early keeps things moving and makes scheduling easier, particularly for larger or more complex homes.

Landlords in Southwark

Landlords need a valid EPC before marketing a rental property in Southwark. The certificate also helps show whether the property meets the Minimum Energy Efficiency Standards (MEES). In practice the EPC is more than paperwork — it can highlight insulation, glazing or heating improvements worth considering before the property is let.

Selling a home in Southwark

When selling a property in Southwark, an EPC is generally required before it goes on the market. Booking it ahead of time avoids last-minute delays, and the recommendations may point to low-cost ways to improve the rating.

EPC data for Southwark

Figures below are for the Southwark local authority area, from the Energy Performance of Buildings Register to 2026 Q2.

4,818EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 55% of certificates
33%Rated D or below, against 46% nationally
£579Average 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 Southwark rates

Share of the 37,026 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

80% of the certificates lodged here are for flats and maisonettes, where houses lead nationally. The average floor area is 73m², roughly 12m² smaller than the England and Wales average. Estimated heating costs average £579 a year, £360 a year below the national figure. 46% of certificates were lodged for rented homes, a notably high share, so Minimum Energy Efficiency Standards bite harder here.

Radon in Southwark

Southwark 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 Southwark centre show 69 conservation areas, 1,098 listed buildings and 247 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 Southwark

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.
