Domestic & Commercial Energy Performance Certificates (EPC) Windsor

We provide EPCs in Windsor and across Windsor and Maidenhead for both Domestic and Commercial properties. A valid EPC is required to be in place before the sale or rental of your property. The EPC survey itself is entirely non intrusive and won't damage the building in any way. Once the survey is complete the EPC report will be produced, which gives the building an Energy Performance Rating rating on a scale from A to G.

For most rental properties an EPC rating of E or better is required, in compliance with the Minimum Energy Efficiency (MEES) legislations of 2018. For properties for sale, MEES legislation does not yet apply, however an ever increasing number of financial institutions require properties to demonstrate they would be MEES compliant before agreeing mortgage funding.

Across Windsor, the most common domestic EPC band is C, with 52% of homes rated C or above and an average energy-efficiency score of 67 out of 100. Commercial properties in the wider Windsor and Maidenhead area have an average rating of C 66 (UK average D 77).

There is real room to improve: the average Windsor home could raise its score by about 13 points, and 58% could improve by 10 points or more. The average home here emits roughly 3.4 tonnes of CO₂ a year.

Around 56% of homes in Windsor are owner-occupied and 30% are privately rented. About 56% are houses and 35% flats, and 81% are heated by mains gas. On the fabric, 68% have insulated cavity walls and 86% are fully double-glazed or better.

Letting a property in Windsor? About 50% of privately rented homes here are rated below an EPC C, the level the government has proposed as a future minimum for rented homes, and 0.6% are rated F or G, below the EPC E minimum needed to let a home today. We can carry out the EPC and advise on the most cost-effective way to improve the rating.

New-build makes up about 8% of certificates in Windsor, averaging a band B. New builds need a SAP calculation and an as-built EPC, both of which we provide.

These figures are from analysis of the 10,235 currently valid domestic EPCs for Windsor in the publicly available government data set, covering certificates lodged in the ten years to 2026-08-16 (one per property, its latest). Values are medians/averages from the source data.

EPC statistics on this page are derived from the Ministry of Housing, Communities & Local Government (MHCLG) Energy Performance of Buildings Data, licensed under the Open Government Licence v3.0.

What EPCs in Windsor most often recommend

Every EPC lists the improvements that would raise the home's rating. Across 10,235 valid certificates in Windsor, the typical home is rated C 69 and could reach C 80 with the measures its EPC recommends. The most frequent are:

Solar photovoltaic panels, 2.5 kWp — recommended on 56% of Windsor EPCs, typically £3,500 - £5,500.
Solar water heating — recommended on 44% of Windsor EPCs, typically £4,000 - £6,000.
Floor insulation (solid floor) — recommended on 32% of Windsor EPCs, typically £4,000 - £6,000.
Low energy lighting for all fixed outlets — recommended on 32% of Windsor EPCs, typically £20.
50 mm internal or external wall insulation — recommended on 28% of Windsor EPCs, typically £4,000 - £14,000.
Cavity wall insulation — recommended on 19% of Windsor EPCs, typically £500 - £1,500.

For landlords the list matters: 50% of privately rented homes in Windsor are currently below band C, the minimum for new tenancies from 1 October 2030. Your EPC's own recommendations are the starting point for the plan.

Cost ranges are the register's indicative figures, not quotes. Book an EPC in Windsor and the certificate will list the measures for your home.

For properties for which we have produced an EPC in Windsor, if shown not to meet MEES targets, we can then provide tailored advice on the least disruptive and most cost effective ways to improve the building to achieve the targeted rating. We are happy to provide more in depth MEES advice, including on MEES Exemptions so please Contact Us for more information.

Domestic EPCs

Carried out by one of our fully accredited Domestic Energy Assessors (DEA), the EPC survey will look at the way the property is constructed, heated (including water heating), insulated, ventilated and lit. The survey does not look at the way the property is used by the residents, so excludes appliances and does not take into account things such heating patterns, instead using a standard set of assumptions about how the house is lived in. This allows for a fair comparison between different properties.

The survey is entirely non invasive. The assessor will not drill any holes or unscrew any access panels. For any insulation added to the property since its original date of construction to be included, the assessor will need to be able to visually evidence it on the day (over 75% of its area for loft insulation, and in multiple locations for wall insulation), or be provided with documentary evidence, such as an installer's receipt.

Where neither documentary evidence or visual inspection can be used to evidence insulation, the assessor will class this element as ‘as built’. The EPC calculation will then make an assumption about what is there, based on the age of the building and the building regulations that were in place at the time of construction. The assessor does not make, or have any control over, these assumptions.

It usually takes around 30 mins to conduct an EPC survey for an average 3 bedroom house. There is then a 2 working day processing period after which you will receive an invoice, followed by the EPC documents immediately on payment.

We are happy to provide more in depth advice on Domestic EPCs, including on Domestic EPC exemptions. so please Contact Us for more information.

Commercial EPCs

Carried out by one of our fully accredited Non-Domestic Energy Assessors (NDEA), the Commercial EPC survey will look at the way the property is constructed, conditioned (including for water heating), insulated, ventilated and lit. It also takes into account the different activities that take place within each zone of the property.

The Commercial EPC survey is entirely non invasive. The assessor will not drill any holes or unscrew any access panels. Any elements of the building and its systems that cannot be visually inspected during the site visit can also be accounted for by documentary evidence. In order to achieve the most accurate rating, you can provide in advance, or make available on the day, any documentation you may have relating to the construction of the building and the make and model of any HVAC systems, lighting designs etc.

For any elements of the building that can not be visually inspected or evidenced by documentation, a set of default assumptions have to be made. These assumptions use ‘worse case scenario’ default values, and as such can lead to a worse EPC rating. The Commercial EPC process does not take into account energy used by commercial processes taking place within the building, such as manufacturing, food preparation etc, to allow a fair comparison between buildings. more information.

Our surveyor will need access to all parts of the building, including any plant rooms. They will take a set of measurements, notes and photographs of various elements of the building. For a Commercial EPC in Windsor on a building sized such as, for example, a regular single storey coffee shop, the site visit usually takes approximately 30 minutes. Survey time is however dependent on the size and the complexity of the property, so may take several hours or more for a complex building such as a large care home.

Once our assessor has visited the site, all the data collected will be used to make a 3d model of the building in specialist software. From this an EPC calculation will be run, using the Simplified Building Energy Model (SBEM) methodology, giving the building an EPC score on an A+ to G scale. This score relates to how much CO₂ was produced generating the energy to condition, light, ventilate and provide domestic hot water for the building.

Alongside the EPC report, the SBEM calculation also provides a Recommendation Report (RR), however this report, which is automatically generated by the software, is very generic, so alongside your Commercial EPC in Windsor we can also provide a much more specifically tailored report examining the least disruptive and most cost effective ways to achieve a target EPC rating. This is in the form of our Minimum Energy Efficiency Standards (MEES) reports.
