What is an EPC?
An Energy Performance Certificate (EPC) is a legal document that rates a property's energy efficiency on a scale from A (most efficient) to G (least efficient). It is required by UK law whenever a property is sold, rented, or newly built. EPCs are produced by qualified, accredited Domestic Energy Assessors (DEAs) and are valid for 10 years.
When Do You Need an EPC?
You are legally required to have a valid EPC in the following situations:
- Selling a property — an EPC must be available before marketing begins
- Renting a property — landlords must provide an EPC to prospective tenants
- Building a new property — an EPC is required on completion
- Applying for green grants — many government schemes require a current EPC
- Remortgaging — some lenders now require a valid EPC
Failure to provide an EPC when required can result in a fine of up to £5,000 for commercial properties and up to £200 for domestic properties.
What Does an EPC Show?
Your EPC provides two key ratings:
- Current Energy Efficiency Rating — how efficient the property is right now
- Potential Energy Efficiency Rating — how efficient it could be with recommended improvements
It also includes a detailed list of recommended improvements — such as upgrading insulation, installing a more efficient boiler, or adding solar panels — along with estimated cost savings for each.
EPC Ratings Explained
| Rating | Band | Efficiency |
|---|---|---|
| A | 92–100 | Highest efficiency — very low energy costs |
| B | 81–91 | Excellent — well-insulated, modern systems |
| C | 69–80 | Good — above average for UK homes |
| D | 55–68 | Average — most UK homes fall here |
| E | 39–54 | Below average — minimum for rental properties |
| F | 21–38 | Poor — cannot legally be rented without exemption |
| G | 1–20 | Very poor — highest energy costs |
Who Can Carry Out an EPC?
EPCs must be carried out by an accredited Domestic Energy Assessor (DEA) who is registered with an approved accreditation scheme. Move-Nest works with a nationwide network of fully qualified, insured DEAs who are accredited to produce legally compliant EPCs across the UK.
How Much Does an EPC Cost?
EPC prices vary by region, typically ranging from ££75 to £125 for a standard residential property (up to 3 bedrooms). Properties with 4 or more bedrooms may incur a small additional charge of £10 per extra bedroom.

Landlord EPC Requirements
Under the Minimum Energy Efficiency Standards (MEES), landlords in England and Wales must ensure their rental properties achieve a minimum EPC rating of E before granting a new tenancy. Properties rated F or G cannot legally be let unless a valid exemption is registered.
If your property doesn't meet the minimum standard, your EPC report will include recommendations for improvements. See our guide on how to improve your EPC rating for practical steps.
Frequently Asked Questions
How long does an EPC assessment take?
A typical domestic EPC assessment takes 30 to 60 minutes depending on the size and complexity of the property. The assessor will need access to all rooms, the loft space (if accessible), and the boiler.
How long is an EPC valid for?
An EPC is valid for 10 years from the date of issue. You can reuse an existing valid EPC unless major energy-related renovations have been carried out since it was produced.
Can I use an old EPC?
Yes, provided it is still within its 10-year validity period. However, if you've made significant improvements (new boiler, insulation, double glazing), a new EPC will reflect the better rating and could help with selling or letting.
Can you fail an EPC?
No — you cannot "fail" an EPC. Every property receives a rating from A to G. However, landlords must achieve a minimum rating of E to legally rent a property. If your property is rated F or G, you'll need to make improvements or apply for an exemption.
What happens during an EPC assessment?
The assessor will inspect the property's construction, insulation, heating systems, windows, lighting, and hot water systems. They may take measurements and photographs. No preparation is needed, but please ensure all rooms and the boiler are accessible.
How quickly can I get an EPC?
With Move-Nest, appointments are often available within 24–48 hours. After the assessment, your EPC is typically lodged on the government register and emailed to you within 24 hours.
