EPC Chadwell St Mary

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.

Property in Chadwell St Mary 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 the assessor looks at

The assessment is a straightforward survey in which the assessor records the property's key characteristics, 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

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 quickly can I book an EPC in Chadwell St Mary?

Many people looking for an EPC in Chadwell St Mary already have a sale, letting or listing under way. An estate agent may have asked for the certificate before marketing begins, or a landlord may need one before advertising a rental. Booking early helps avoid delays and gives the assessor more flexibility with older or larger properties.

EPC data for Chadwell St Mary

Figures below are for Thurrock, the local authority covering Chadwell St Mary, from the Energy Performance of Buildings Register to 2026 Q2.

2,889EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 51% of certificates
44%Rated D or below, against 46% nationally
£748Average 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 Thurrock rates

Share of the 20,803 certificates lodged in the five years to 2026 Q2. This is the certificates lodged, not a survey of every home in the area.

Radon in Chadwell St Mary

Chadwell St Mary 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 1 and 3 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 Chadwell St Mary centre show 1 conservation area. 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 Chadwell St Mary

An EPC around here generally costs between £80 and £185, 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.
