EPC Cost Calculator
Estimate the cost of an Energy Performance Certificate
Last updated: July 2026
How much does an EPC cost?
An EPC – Energy Performance Certificate – rates a property’s energy efficiency from A to G and is legally required whenever a home is built, sold or let. For a domestic property the cost is modest and driven mainly by size: a small flat is around £35–£70 and a large house up to about £150, while commercial premises cost more. This calculator gives an indicative price for your property, reminds you that an EPC lasts ten years (so you may not need a new one), and flags the minimum rating you need if you are letting. It sizes the cost; it is not a quote.
What you need to know
- Required to build, sell or let – the seller or landlord must commission the EPC and make it available; it should be ordered before marketing.
- Valid for ten years – check the EPC register before paying, because an existing unexpired certificate can be reused.
- Letting: MEES minimum E – in England & Wales most rented homes must be at least EPC E unless an exemption is registered, and the Government has proposed tightening this.
- Priced by size – a bigger property has more for the assessor to record, so it costs more. Commercial EPCs are dearer and depend on floor area.
Worked example
A landlord letting a 2-bed flat needs a valid EPC. A domestic EPC for that size is around £35–£70, but first they check the EPC register and find one lodged eight years ago that is still valid – so they pay nothing and reuse it. They do confirm the rating is at least E to meet MEES; if it were F or G, they would need to improve the property or register an exemption before letting.
Frequently asked questions
How much does an EPC cost?
A domestic EPC typically costs between about £35 and £150 in the UK, depending on the size of the property and your area. A small flat is at the lower end and a large detached house at the top. Commercial EPCs cost more because they are more complex.
When is an EPC legally required?
You must have a valid EPC whenever a property is built, sold or let. A seller or landlord has to commission it, make it available to buyers or tenants, and it must be ordered before the property is marketed.
How long does an EPC last?
An EPC is valid for ten years. If you already have one that has not expired you can reuse it for a sale or a new tenancy, so it is worth checking the EPC register before paying for a new assessment.
What is the minimum EPC rating to let a property?
Under the Minimum Energy Efficiency Standards (MEES) in England and Wales, most rented homes must have an EPC rating of at least E. Letting a property below E without a valid exemption can lead to a financial penalty, and the Government has proposed raising the minimum in future.
Who can produce an EPC?
A domestic EPC must be produced by an accredited Domestic Energy Assessor, who visits the property, records its construction, heating and insulation, and lodges the certificate on the national EPC register. Commercial premises need a non-domestic assessor.
Does property size affect the EPC price?
Yes. A larger property has more rooms, heating and construction detail for the assessor to record, so it takes longer and costs more. A one or two-bed flat is cheapest and a large house the most expensive.
Cost figures are indicative UK market ranges for 2026 and vary by area and assessor – they are not a quote. When an EPC is required, how long it lasts and the MEES minimum are set out at GOV.UK – Energy Performance Certificates.
