What is an EPC?

What is an
EPC?

An Energy Performance Certificate (EPC) rates the energy efficiency of a building on a scale from A (most efficient) to G (least efficient). It also estimates the environmental impact of the property using a CO2 rating.

The EPC includes recommendations for improving the energy rating, along with estimated costs and potential savings. For rental properties, the legal minimum EPC rating is currently E, properties rated F or G cannot legally be let.

EPCs are valid for 10 years and must be lodged on the government's national EPC register. They are required whenever a property is built, sold or rented, estate agents and letting agents typically require one before marketing commences.

Why choose us

Why London
landlords & sellers choose us.

Legal requirement to let or sell

All properties marketed for sale or rent in England must have a valid EPC. Properties with an F or G rating cannot be let to new tenants and face fines of up to £30,000 for non-compliance.

Same-day lodgement

Once our assessor completes the survey, the EPC is lodged on the national register and emailed to you the same day, so you're not held up on a sale or tenancy start date.

Improvement advice included

Every EPC includes a full list of recommended improvements with estimated costs and potential savings, helping you plan energy efficiency upgrades that increase your property's rating.

Combined visits available

We regularly combine EPC assessments with EICR and CP12 surveys in a single visit, saving time and reducing the total cost for landlords with multiple compliance requirements.

Common questions

Questions
answered.

How long does an EPC survey take?
Most properties take 30–60 minutes. The assessor needs access to the loft hatch, boiler and all rooms.
Do I need to be present for the EPC?
Someone must provide access to the whole property, including loft and any outbuildings. You or a tenant can let the assessor in.
My property is rated F, can I still let it?
Not legally to new tenants. We can advise on the most cost-effective improvements to bring the rating to E or above. Common measures include loft insulation, cavity wall insulation and a modern boiler.
Is an EPC the same as an energy audit?
No. An EPC is a standardised rating required for compliance. An energy audit is a more detailed report used for larger-scale energy efficiency projects. The EPC does include improvement recommendations.
Can I use the same EPC for multiple tenancies?
Yes, the EPC is valid for 10 years and can be used for multiple tenancies within that period, provided the rating is still E or above.

The assessment

How a domestic EPC assessment is carried out.

A domestic energy assessment is a survey of the building fabric and the heating, not a test of how much energy you use. The assessor records what the property is built from, what is in the loft, what the windows are, what heats the water and the rooms, and what controls are fitted. Those inputs go into the government approved calculation and the rating comes out of it.

What the assessor needs to see

Access to the loft hatch, the boiler and its controls, the hot water cylinder if there is one, and every room. Assessors have to record what they can see, and the software applies a default assumption where they cannot. Defaults are conservative, so an unseen improvement is an improvement that does not count.

Evidence improves the rating

This is the part most owners miss. If you have had cavity walls filled, a boiler replaced or insulation upgraded, the paperwork raises the score. Installation certificates, guarantees, a boiler commissioning sheet or photographs taken during the work are all accepted evidence. Have them ready on the day rather than after the certificate is lodged.

After the assessment

The certificate is lodged on the national register and is valid for ten years. It comes with a recommendations list showing which measures would move the rating and by how much. If you are acting on that list, it is worth having the domestic assessment repeated once the work is complete, because the improvement only counts when a new certificate is lodged.
