EPC Marlow

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 Marlow 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.

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
  • 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 Marlow?

Many people looking for an EPC in Marlow 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.

EPCs for Marlow landlords

Landlords need a valid EPC before marketing a rental property in Marlow. 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 Marlow

When selling a property in Marlow, 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.

Radon in Marlow

Marlow 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 Marlow centre show 1 conservation area, 171 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 Marlow

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.

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.
