Energy Performance Certificate FAQs

Domestic EPCs start from £75 for most standard properties, including flats and houses up to 3 bedrooms. Larger properties (4+ bedrooms) and unusually complex buildings may be higher. Contact us for a quick quote. All prices include travel within approximately 10 miles of Deganwy. No VAT charged.

Commercial EPC pricing depends on the size and complexity of the property. For smaller units up to 500 m² — such as retail units, small offices or holiday lets — prices start from £190. Larger or more complex properties are quoted individually. We give you a fixed price before booking, so there are no surprises on the day.

No. We do not charge VAT on domestic or commercial EPC assessments. We are not VAT registered.

Yes. If you are a landlord or property manager with several properties to assess, we offer a small reduction per property when booking as a group. Get in touch to discuss your portfolio and we can agree a price before anything is booked.

Look up any EPC at find-energy-certificate.service.gov.uk and search by postcode or certificate reference number. Domestic and commercial certificates are on separate registers. If your certificate is approaching ten years old or the rating no longer meets current requirements, contact us to arrange a new assessment.

An EPC is valid for ten years from the date it was lodged on the official register. You can check whether your existing certificate is still valid at find-energy-certificate.service.gov.uk. If it has expired, you need a new assessment before the property can be marketed for sale or let.

We lodge the certificate on the national EPC register and send you the document and reference number by email. For domestic properties, you will typically receive this within 24 hours of the assessment and always within 48 hours.

A domestic EPC assessment usually takes between 30 and 60 minutes depending on the size of the property. Commercial assessments take longer — we will give you a realistic time estimate when you book so you can plan access accordingly.

The assessor visits the property and records its construction, insulation, heating system, hot water, lighting and floor areas. This typically takes 30 to 60 minutes for a standard domestic property. No tests are carried out and nothing is disturbed. After the visit, the data is processed using approved software and the certificate is lodged on the official register.

Yes. We cover North Wales and can often fit bookings in within a few days. If you have an urgent requirement, for example a sale completing soon, call or WhatsApp us directly and we will do our best to accommodate you quickly.

Access to all rooms and the loft hatch (if there is one) helps. If you have paperwork for energy improvements already made, such as insulation certificates, boiler installation records or double-glazing certificates, have these available. They can improve the rating. The assessor does not need anything specific beforehand.

All privately rented properties in England and Wales must have a minimum EPC rating of E to be legally let. Properties rated F or G cannot be let without a valid exemption registered on the PRS Exemptions Register. The Government has proposed raising this minimum to C by October 2030.

Someone needs to provide access to the property, but you do not need to stay for the whole visit. A letting agent, tenant or trusted keyholder can let the assessor in. We just need access to all rooms, including loft space.

The certificate shows the property's current energy efficiency rating from A (most efficient) to G (least efficient) and a potential rating showing what could be achieved with improvements. It also lists specific improvements that would make the biggest difference, with estimated costs and savings. The certificate is valid for ten years.

Landlords who let properties that do not meet the minimum standard without a valid exemption can face fines of up to £5,000 per property. Local authorities enforce the rules and can prohibit letting until improvements are made. The rules apply to each property individually.

You cannot legally let an F or G rated domestic property without registering a valid exemption on the PRS Exemptions Register. Get a current EPC first. The recommendations section shows what improvements would raise the rating and at what cost. Some properties qualify for the cost-cap exemption (currently £3,500) if the improvements required exceed that threshold.

The UK Government has proposed that all privately rented properties must achieve a minimum EPC rating of C by October 2030. As of April 2026, this is not yet law, but the direction is clear. Landlords who act now have time to plan improvements, get quotes and spread costs rather than being rushed by a deadline.

Exemptions exist where the cost of all relevant improvements would exceed the £3,500 cost cap, where improvements are not technically feasible, where a third party (such as a freeholder or tenant) has refused consent, or where improvements would devalue the property by more than 5%. All exemptions must be registered on the PRS Exemptions Register and are valid for five years.

Not necessarily. If you have a valid EPC (under ten years old) that meets the required rating, it can be used for subsequent tenancies. You must give a copy of the EPC to any new tenant before they move in. If the certificate has expired or the rating no longer meets the minimum standard, you need a new assessment.

The landlord is responsible for obtaining and providing a valid EPC. Tenants do not arrange or pay for one. The EPC must be made available to prospective tenants when a property is first marketed and provided before they move in.

Some properties are exempt: listed buildings where energy efficiency improvements would unacceptably alter their character, buildings used for worship, industrial sites and non-residential agricultural buildings with low energy demand, and holiday accommodation rented for fewer than four months per year. If you think your property may qualify, speak to us before assuming an exemption applies.

The most common improvements are loft insulation, cavity or solid wall insulation, a more efficient boiler, heating controls (thermostats and TRVs), solar panels, and double or triple glazing. The EPC report lists the specific recommendations for your property along with estimated costs and the expected impact on the rating.

Yes. A House in Multiple Occupation requires a valid domestic EPC in the same way as any other rented property. The assessment covers the whole building, not individual rooms. MEES rules apply to HMOs in the same way as single-let properties.

An Energy Performance Certificate rates a property's energy efficiency from A (most efficient) to G (least efficient). It is produced by an accredited assessor following a site visit and includes recommendations for improvements. EPCs are legally required when a property is sold, let or newly constructed.

Yes. A valid EPC must be available to prospective buyers before a residential property is marketed for sale. You cannot wait until completion. Order it before the property is listed. Estate agents must include the EPC rating in property listings.

Holiday lets that are commercially operated, for example marketed through booking platforms or letting agents as tourist accommodation, generally require a commercial EPC rather than a domestic one. If you are unsure which type applies to your property, contact us before booking and we will advise.

A domestic EPC uses the RdSAP methodology and applies to residential properties. A commercial EPC uses SBEM (Simplified Building Energy Model) and applies to non-domestic buildings. The scale is the same (A to G) but the assessment process and accreditation requirements are different. Holiday lets often fall into the commercial category even if the building looks residential.
