What is an EPC?

Energy Performance Certificates (EPCs) are an important aspect of the energy efficiency of buildings in Southampton and the UK. An EPC provides a comprehensive overview of a building’s energy performance, including an assessment of its current energy efficiency and recommendations for improvement. Homeowners and landlords in Southampton are required to have an EPC before they can sell or rent their property, making it a crucial part of the property market.

An EPC includes information on the type of building, its construction, and the heating, lighting, and hot water systems. It also provides an energy efficiency rating, which ranges from A (the most efficient) to G (the least efficient). This rating is displayed in a graph, making it easy for homeowners and landlords to understand the energy performance of their property.

Benefits of EPC to Homeowners and Landlords in Southampton

Having an EPC can provide several benefits for homeowners and landlords in Southampton. For example, an EPC can help to increase the value of a property by highlighting ways to improve its energy efficiency. This can be especially important for properties that have a lower energy efficiency rating, as potential buyers or tenants may be put off by high energy bills. By making improvements to the energy efficiency of a building, homeowners and landlords can reduce energy bills and make their properties more attractive to buyers and tenants.

In addition to providing a comprehensive overview of a building’s energy performance, an EPC also provides recommendations for improvement. These may include simple, cost-effective measures such as installing low-energy lighting or improving insulation, or more substantial changes such as upgrading the heating system. These recommendations can help homeowners and landlords to identify areas where they can reduce energy usage and make their properties more environmentally friendly.

Another advantage of having an EPC is that it provides a clear and objective assessment of a building’s energy performance. This can be particularly useful for landlords, as it provides a baseline for energy usage and allows them to monitor energy bills and identify any changes in usage. This can help landlords to identify areas where they can improve the energy efficiency of their properties and reduce energy bills for their tenants.

What are the Government Regulations?

In order to ensure that all homeowners and landlords in Southampton are aware of their obligations regarding EPCs, the government has put in place a number of regulations. For example, it is now illegal to advertise a property for sale or rent without first obtaining an EPC. Regulations state that all commercial properties must have an EPC rating of D or above before they can be let or sold. If a commercial property does not have an EPC rating of D or above, the owner must make improvements to the property until it meets the required standard.

What Access Does an EPC Assessor Need When Inspecting a Property?

An Energy Performance Certificate (EPC) assessor typically needs access to various parts of a property in order to carry out an assessment and produce an accurate EPC rating. Here are some of the areas they may need to access:

  1. All rooms within the property, including bedrooms, living rooms, kitchens, and bathrooms.
  2. Loft spaces, including any loft hatches or access points.
  3. Cavity walls and loft insulation.
  4. Heating and hot water systems, including boilers, radiators, and thermostats.
  5. Electrical systems, including fuse boxes, switches, and sockets.
  6. Any renewable energy systems, such as solar panels or wind turbines.

It’s also important that the assessor is able to view any documents related to the property, such as building plans, as well as any relevant bills for energy use. This will allow them to make an accurate assessment of the property’s energy efficiency and produce an EPC rating.

EPC data for Southampton

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

4,062EPCs reach their 10-year expiry in the next 12 months
Band CThe most common rating, on 48% of certificates
45%Rated D or below, against 46% nationally
£719Average 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 Southampton rates

Share of the 32,153 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 flats and maisonettes, where houses lead nationally. The average floor area is 73.1m², roughly 12m² smaller than the England and Wales average. Estimated heating costs average £719 a year, £220 a year below the national figure. 48% of certificates were lodged for rented homes, a notably high share, so Minimum Energy Efficiency Standards bite harder here.

Radon in Southampton

Southampton 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 Southampton centre show 19 conservation areas, 371 listed buildings and 6 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 Southampton

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.
