What Is an Energy Performance Certificate?
An Energy Performance Certificate (EPC) is an official document that rates the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). It provides a clear picture of how much energy your property uses and what it costs to heat and power.
Beyond compliance, an EPC provides valuable recommendations on how to improve your property’s energy efficiency. This helps reduce energy bills, lower your carbon footprint, and increase your property’s market value.
In the UK, an EPC is a legal requirement whenever you sell, rent, or build a property. Landlords must provide an EPC to prospective tenants, and sellers must make one available to potential buyers before marketing their property. Without a valid EPC, you could face fines of up to £5,000.

Who Needs an EPC?
If you’re selling, renting, or building a property in the UK, you legally need an Energy Performance Certificate.
Landlords
A valid EPC is mandatory before letting a property. Ensure your rental meets the minimum E rating to avoid penalties.
Homeowners Selling
An EPC must be available to prospective buyers from the point of marketing. A good rating can boost your sale price.
Commercial Property Owners
Non-domestic EPCs are required for commercial properties being sold or let. We cover offices, retail, and industrial units.
Letting Agents
Agents must ensure a valid EPC is in place before marketing a property for rent. We offer fast turnaround for agencies.
New Build Developers
New constructions require an EPC before occupation. We work with developers to ensure SAP assessments and compliance.
Why EPC is Important
Gas safety isn't just a legal requirement—it's a critical measure to protect lives and property. Understanding the risks helps you make informed decisions about your home's safety.
Why Energy Efficiency Matters
A good energy efficiency rating doesn’t just lower your bills — it enhances comfort, reduces carbon emissions, and increases property value. Whether you’re selling, renting, or looking to improve your home, understanding your property’s energy performance is key.
Lower Energy Bills & Carbon Emissions
Properties with high efficiency (like A or B on the EPC scale) use less energy for heating and lighting, meaning lower monthly energy costs and a smaller carbon footprint.
Better Market Value & Tenant Appeal
An efficient home is more attractive to buyers and renters. Having a strong EPC rating can make your property stand out — and potentially increase its market value or rental appeal.
Regulatory Compliance for Renting or Selling
For landlords or sellers in the UK, a valid EPC is often legally required before marketing a property. Ensuring compliance avoids fines or legal issues.
Don’t Wait — Upgrade and Save
If your property has a low EPC rating (E, F or G), consider upgrading insulation, heating, windows or other efficiency improvements. A small investment now can boost your rating, reduce bills, and increase your home’s value.

Current Rating
Your current EPC rating reflects the energy efficiency of your property as it stands today. This is based on factors like insulation levels, heating systems, glazing, and lighting.
Potential Rating
The potential rating shows what your property could achieve if all recommended improvements were implemented. This helps you prioritise upgrades for maximum impact.

How much does an EPC cost?
Our domestic EPCs start from £70 for homes up to 4 bedrooms / 99 m². Fill in the form with your details for an exact quote.
Are your assessors certified and qualified?
Yes. Your EPC is carried out by a fully qualified Domestic Energy Assessor accredited with Elmhurst Energy, one of the UK’s largest schemes. Every certificate is official and lodged on the government register.
How quickly will I receive my certificate?
Fast, you’ll usually have your digital certificate within 24 hours of the assessment, and always within 48. Submit your details and we’ll arrange a convenient time.
How long does the on-site assessment take?
For most homes, around 20-45 minutes. Larger or more complex properties may take a little longer.
Do you provide the certificate digitally?
Yes, all certificates are issued digitally for convenience, with hard copies available on request.
How can I improve my EPC rating?
Common improvements include loft and cavity wall insulation, double or triple glazing, a modern A-rated condensing boiler, and low-energy LED lighting. Your EPC includes recommendations tailored to your property.
What happens if my property is rated F or G?
If you’re letting it, you’ll usually need to bring it up to at least an E before you can rent it out (unless a valid exemption applies). We’ll advise the most cost-effective way to get there.
Can homeowners book too, or is it just for landlords?
Both, whether you are a homeowner selling, a landlord letting, or an agent, we can help.
