Domestic Energy Performance Certificates
What is an EPC?
An Energy Performance Certificate (EPC) is a legally required document that rates the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). In the UK, an EPC is mandatory when selling or renting a residential property, and it must be provided before potential buyers or tenants view the property.
The EPC includes recommendations for cost-effective improvements to reduce energy consumption and carbon emissions. This makes it an invaluable tool not just for legal compliance — but for homeowners looking to improve their property's energy efficiency, reduce running costs, and access government-backed funding schemes such as the Boiler Upgrade Scheme (BUS) and other retrofit grants.
Once issued, an EPC is valid for 10 years and is automatically lodged on the national register, giving you a permanent record of your property's energy rating.

Our accredited assessor will visit for 30–60 minutes, taking measurements, checking heating systems, insulation, and windows to evaluate energy performance.
Assessment Completed
Data is processed and your property is rated on the A–G scale with tailored recommendations for energy improvements.
Certificate Lodged Within 48 Hours
Your EPC is emailed immediately and registered on the national database, ready to use for selling, letting, or accessing government funding and retrofit schemes.
Who Needs an EPC?
Homeowners Selling
If you're selling your home, an EPC is a legal requirement before marketing. It helps potential buyers understand the property's energy efficiency and running costs at a glance.
Landlords
Landlords must provide an EPC when letting a property. It gives tenants transparency about energy bills and supports compliance with energy efficiency regulations.
Estate & Letting Agents
Estate & letting agents need EPCs to market properties effectively. Properties with valid EPCs get faster enquiries and help agents meet their legal obligations and client expectations.
Homeowners Improving Their Property
You don't have to be selling to benefit from an EPC. Homeowners making energy improvements — such as installing a heat pump, upgrading insulation, or applying for government grants — often need an up-to-date EPC as part of the process.
Could Your EPC Unlock Government Funding?
Many government-backed energy efficiency schemes require a valid EPC before you can apply. Getting your certificate is often the first step towards accessing significant funding to improve your home.
Boiler Upgrade Scheme (BUS)
The BUS offers grants of up to £7,500 towards the cost of installing a heat pump or biomass boiler. An EPC is required to confirm your property's eligibility — the property must have a valid EPC with no outstanding recommendations for loft or cavity wall insulation.
ECO4 & Great British Insulation Scheme
The ECO4 scheme and the Great British Insulation Scheme both use EPC data to identify eligible properties and fund insulation and heating upgrades. A current EPC is essential to demonstrate your property's starting energy rating.
Future-Proofing Your Home
As energy costs continue to rise and government targets tighten, knowing your property's current EPC rating is invaluable. It gives you a clear roadmap for improvements and ensures you're well placed to take advantage of any future funding opportunities.
Common EPC Questions
Do I legally need an EPC to sell my house?
Yes. An EPC is a legal requirement before marketing a residential property for sale or rent in England and Wales. It must be available to prospective buyers or tenants before viewings take place.
How long is an EPC valid for?
An EPC is valid for 10 years from the date of issue. It is automatically lodged on the national EPC register, where it can be accessed by owners, agents and buyers.
Can an EPC help me get a government grant?
Yes. A valid EPC is a prerequisite for several government schemes — including the Boiler Upgrade Scheme (grants of up to £7,500 for heat pumps), ECO4, and the Great British Insulation Scheme. Getting your EPC is often the essential first step.
What is the minimum EPC rating for renting?
In England and Wales, rental properties must currently have a minimum EPC rating of E. The government has proposed raising this to a C rating for new tenancies in future — making a current EPC an important investment for landlords.
