EPCs for Windsor's older and newer homes
Windsor has everything from Victorian and Edwardian terraces to modern apartments and larger detached homes around Clewer and Old Windsor.
Older properties aren't automatically going to receive a poor EPC rating. During the assessment, we'll look at the property's construction, insulation, heating, windows and lighting and identify any improvements that could help.
Most privately rented properties must meet the minimum EPC requirements under the current MEES rules, subject to applicable exemptions. If you're a landlord and you're unsure what applies to your property, contact us.
We cover Windsor, including the town centre, Clewer and Old Windsor, as well as nearby Datchet, Eton and Wraysbury.
EPC Ratings in Windsor: What the Local Data Shows
If you're buying, selling or renting a property in Windsor, its energy performance can make an important difference to running costs, future improvements and the property's overall appeal. Recent EPC data gives us a useful picture of energy efficiency in the Windsor area. Across the wider Windsor and Maidenhead local authority, around 56% of homes with an EPC are currently rated below C, while around 44% are rated A–C. The most common EPC rating is D.
Windsor is largely covered by the SL4 postcode area. Analysis of 13,517 properties with EPC records in SL4 shows the following distribution;
A: 0%
B: 9%
C: 35%
D: 38%
E: 14%
F: 3%
G: 1%
These figures include a mixture of houses, flats, bungalows and other residential property types, so the EPC rating of an individual Windsor property can be very different from the area average.

What does this mean for Windsor homeowners and landlords?
A lower EPC rating does not necessarily mean that a property has a serious problem. Older homes, period properties, solid-wall construction and properties with older heating systems can all affect energy performance.
Before an EPC assessment, it can be useful to have information available about your:
Boiler and heating system
Loft insulation
Windows and glazing
Hot-water cylinder
Renewable-energy systems
Previous improvements
An EPC assessment looks at the property's construction, heating, insulation, windows, lighting and other relevant features to produce an energy-efficiency rating from A to G.
If you're preparing a property for sale or letting, an up-to-date EPC gives you a clear picture of its current rating and the improvements that may help increase its energy efficiency.

Frequently Asked Questions
How much does an EPC cost in Windsor?
An EPC in Windsor costs £95 for a studio or one-bedroom property, £120 for two bedrooms, £135 for three, £150 for four, £170 for five and £200 for six or more. Every price is fixed, includes the government lodgement fee, and carries no call-out charge anywhere in SL4.
How do I get an EPC in Windsor?
Four steps: 1) Check the gov.uk Find an Energy Certificate register first, because an EPC lasts 10 years and your home may already have one. 2) Book a fixed-price visit online, from £95 for a studio or one-bed to £200 for six bedrooms. 3) The visit takes 45 to 60 minutes anywhere in SL4, from the town centre to Clewer. 4) Your certificate is lodged on the government register and emailed to you within 24 hours, not the 48 hours some Windsor providers quote.
How long is an EPC valid for?
An EPC is normally valid for 10 years from the date it is issued. A new EPC may be required sooner if you want an up-to-date certificate following significant changes or improvements to the property.
Do Windsor's historic properties near the town centre score badly?
Not necessarily. Older Victorian and Edwardian homes can achieve a good EPC rating, depending on their construction, heating, insulation, windows and other features. During the assessment, we'll identify the relevant characteristics of the property and record suitable improvement recommendations.
Do I need an EPC to sell a property in Windsor?
Yes. In most cases, a property being marketed for sale in England must have a valid EPC available to prospective buyers. We can assess houses, flats and other domestic properties throughout Windsor and the surrounding SL4 area.
Do I need an EPC to rent out a property in Windsor?
Yes. Landlords generally need a valid EPC before marketing a property for rent, subject to certain exemptions. We provide EPC assessments for landlords across Windsor, including houses, flats and other domestic rental properties.
How long does an EPC assessment take in Windsor?
Most Windsor assessments take about 45 minutes for a studio or one-bedroom flat and around an hour for a larger house, all in a single visit. The certificate is normally lodged on the government register within 24 hours of the appointment, and often the same day.
What do I need to do before my Windsor EPC assessment?
It helps to make sure we can access the main rooms, loft if applicable, heating controls, hot-water cylinder and other relevant areas of the property. Information about the boiler, windows, insulation and previous improvements can also be useful.
What happens during an EPC assessment?
We'll inspect the property and collect information about its size, construction, insulation, windows, heating, hot water, lighting and other relevant features. This information is used to produce the property's energy-efficiency rating and recommendations.
Can I improve my EPC rating before selling or letting my Windsor property?
Potentially, yes. Improvements such as better insulation, more efficient heating, glazing and energy-efficient lighting can affect EPC performance. We can explain the recommendations shown on the completed certificate and help you understand which improvements may be relevant to your property.
Do I need a new EPC if I have recently bought a property in Windsor?
Not necessarily. An EPC normally remains valid for 10 years and belongs to the property rather than the current owner. If a valid EPC already exists, a new assessment may not be required unless you want an updated certificate.
Do you cover Clewer, Eton, Old Windsor and Datchet?
Yes. We cover Windsor and surrounding areas including Clewer, Eton, Old Windsor, Datchet and Wraysbury, as well as other nearby locations. See our local service-area pages for more information.
