What is an EPC and What Does it Assess?

An Energy Performance Certificate (EPC) assesses the overall energy efficiency of a property by looking at various factors such as insulation levels, lighting, heating systems and ventilation. The assessor evaluates the current condition of these features and then assigns a grade based on their findings. An EPC report will also include information on how to improve the energy efficiency of your home or rental property. This includes suggestions such as updating old appliances, installing double-glazed windows or adding more insulation in walls or attic spaces.

Benefits of an EPC

Having an up-to-date EPC can help homeowners and landlords save money in several ways. First, if you are selling your property, potential buyers may be more interested in purchasing your home if they know that it has been assessed with an up-to-date Energy Performance Certificate. Additionally, having better energy efficiency can reduce your utility bills over time because you won’t be using as much energy to heat or cool your property. Finally, if you are renting out a property, tenants will appreciate the fact that they don’t need to pay as much on their utility bills each month because they know their rental space has been evaluated for its energy efficiency rating.

Government Regulations

In addition to providing financial benefits for homeowners and landlords in Winchester, having an up-to-date EPC also helps them meet government regulations regarding energy efficiency assessments for buildings listed for sale or rent. The UK government requires that all homes listed for sale must have a valid Energy Performance Certificate before they can be sold. Similarly, all residential properties rented out must also have this certificate before being let to tenants. Failure to comply with these government regulations can result in hefty fines for landlords who do not provide their tenants with this document when renting out their properties.

What Specific Things Does an Epc Assessor Look for When They Visit a Property?

An Energy Performance Certificate (EPC) assessor in the UK evaluates the energy efficiency of a property by assessing various aspects of the property’s construction, insulation, heating systems, lighting, and other factors that contribute to its energy efficiency. Here are some specific things that an EPC assessor looks for when they visit a UK property:

  1. Insulation: The assessor checks the insulation in the walls, roof, and floor of the property to see if it meets the current standards.
  2. Heating systems: The assessor evaluates the heating system of the property to see if it’s efficient and suitable for the size and type of the property.
  3. Lighting: The assessor looks at the lighting in the property to see if it’s energy-efficient and suitable for the property’s needs.
  4. Ventilation: The assessor checks the ventilation of the property to ensure that it meets the current standards and that it’s not creating any unnecessary heat loss.
  5. Windows and doors: The assessor looks at the windows and doors of the property to see if they are double-glazed or have any draught-proofing.
  6. Energy-efficient appliances: The assessor looks at the appliances in the property, such as boilers and fridges, to see if they are energy-efficient and meet the current standards.
  7. Renewable energy sources: The assessor evaluates if the property has any renewable energy sources, such as solar panels or wind turbines, to generate its energy.

Overall, an EPC assessor checks the property’s energy efficiency and produces a report that rates the property’s energy efficiency on a scale from A to G, with A being the most efficient and G being the least efficient.

EPC data for Winchester

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

1,880EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 51% of certificates
43%Rated D or below, against 46% nationally
£1,069Average 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 Winchester rates

Share of the 14,054 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

68% of the certificates lodged here are for houses. The average floor area is 107.7m², roughly 23m² larger than the England and Wales average. Estimated heating costs average £1,069 a year, £130 a year above the national figure. 23% of certificates were lodged for rented homes.

Radon in Winchester

Winchester 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 Winchester 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 Winchester

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.
