EPC Southwick

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

An Energy Performance Certificate (EPC) shows how energy efficient a property is and gives it a rating from A (most efficient) to G (least efficient). You will usually need a valid EPC before a home is marketed for sale or rent.

Like most parts of the country, Southwick has a varied housing stock — a mix of older and character homes alongside more modern properties. EPCs are commonly required for terraced, semi-detached and detached houses as well as flats and recent developments.

How an EPC assessment works

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

The assessor then uses this information to calculate the rating and produce a recommendation report. Older or unusually laid-out homes can take a little longer, so it helps to mention any unusual features when you book.

How soon can I get an EPC in Southwick?

If you are selling or letting in Southwick, 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.

EPCs for rental properties in Southwick

Rental homes in Southwick need a valid EPC before they are marketed, and the certificate is the starting point for meeting the landlord MEES requirements. Beyond compliance, it flags the improvements most likely to raise the property's efficiency.

EPCs for homeowners selling a property

If you are selling a house or flat in Southwick, you will usually need an EPC before marketing begins — whatever the property type. Arranging it early is one less thing to deal with once the sale is under way, and the recommendation report can flag quick improvements that may help the rating.

EPC data for Southwick

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

1,115EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 44% of certificates
52%Rated D or below, against 46% nationally
£989Average 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 Adur rates

Share of the 7,684 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

53% of the certificates lodged here are for houses. The average floor area is 83.3m², about the England and Wales average. Estimated heating costs average £989 a year, £50 a year above the national figure. 28% of certificates were lodged for rented homes.

Radon in Southwick

Southwick sits in a radon Affected Area. The UKHSA and British Geological Survey put the 1km square covering the town centre in a band where between 5 and 10 in 100 homes are estimated to be at or above the radon action level of 200 becquerels per cubic metre. Radon is not measured during an EPC survey and does not affect the rating, but if you are buying, selling or improving a home here it is worth a test kit, and worth knowing before you seal a property up: draught-proofing and insulation work can raise indoor radon if ventilation is reduced. 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 Southwick centre show 4 conservation areas, 24 listed buildings and 5 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 Southwick

An EPC around here generally costs between £70 and £170, 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.
