EPC assessment for rental

Since 2018, Minimum Energy Efficiency Standards (MEES) mean most private rental properties must have a rating of at least 'E' to be legally let. Keeping your EPC up to date ensures you remain compliant with UK law and helps your tenants manage their energy bills.

What Does the Work Involve?

• Internal Inspection: The assessor will visit every habitable room, including the kitchen, bathrooms, and any converted loft spaces.
• Structural Assessment: Measuring floor areas and identifying wall construction types (e.g., cavity wall, solid brick, or timber frame).
• Insulation Check: Checking the depth of loft insulation and looking for evidence of cavity wall or floor insulation.
• Heating & Hot Water: Recording the boiler make and model, cylinder details, and the presence of thermostats or thermostatic radiator valves (TRVs).
• Windows & Lighting: Inspecting glazing types (single, double, or triple) and counting the percentage of low-energy lighting.
• Data Lodgement: Inputting all data into accredited RDSAP software to generate the final certificate and lodging it on the national EPC Register.

Typical Costs

Prices vary based on your location and the size of the property. Most assessors charge a fixed fee that includes the government lodgement fee, though travel surcharges may apply for remote rural areas.

How Long Does It Take?

• Small Flats (1-2 beds): 30 to 45 minutes on-site.
• Average Houses (3-4 beds): 45 to 90 minutes on-site.
• Large/Complex Properties: 2 hours or more, especially if there are multiple extensions or heating systems.
• Report Turnaround: Usually emailed to the landlord within 24–48 hours of the site visit.

DIY or Professional?

You cannot carry out an EPC assessment yourself. By law, an EPC must be produced by an accredited Domestic Energy Assessor (DEA) who is registered with a government-approved scheme such as Elmhurst or Stroma.

Assessors must have professional indemnity insurance and valid accreditation to ensure the certificate is legally recognised for property transactions or rentals.

Choosing the Right Tradesperson

• Verify Accreditation: Ask for their assessor ID and check it against the official EPC Register.
• Local Knowledge: Choose someone local to avoid high travel surcharges and ensure they understand regional building styles.
• Check Reviews: Look for feedback regarding punctuality and how quickly they upload the final report.
• Ask about "Drafts": Ask if they can provide a draft result before lodgement if you are worried about hitting a specific rating.

UK Regulations

• MEES Regulations: It is currently illegal to start a new tenancy (or renew an existing one) if the property has an EPC rating of F or G.
• Validity: An EPC is valid for 10 years. However, if you make significant energy improvements, it is wise to get a new one to reflect the higher rating.
• Display Requirements: Landlords must provide a copy of the EPC to any prospective tenant free of charge.
• Enforcement: Local authorities can issue fines of up to £5,000 for non-compliance with MEES regulations.

Common Problems

• No Loft Access: If the assessor cannot see the insulation, they must enter "unknown," which often defaults to a poor rating.
• Missing Paperwork: Without invoices or certificates for cavity wall insulation or floor insulation, the software assumes the worst-case scenario based on the age of the house.
• Locked Rooms: Every room must be inspected; if the assessor can't gain entry, the assessment may be incomplete or delayed.
• Old Lighting: A simple lack of LED bulbs can sometimes drop a property by several points, potentially moving it down a grade.

Frequently Asked Questions

Does my rental property definitely need an EPC?

Yes, almost all self-contained rental properties in the UK require an EPC. Exceptions are rare and usually only apply to listed buildings where certain energy improvements would unacceptably alter their character.

What happens if my property gets an F or G rating?

You will likely be unable to legally rent the property. You must carry out energy efficiency improvements up to a cost cap of £3,500 (inc. VAT) to bring it up to an E rating or apply for an exemption if the costs exceed this.

Can I use an old EPC if I’ve recently renovated?

An EPC lasts 10 years, so it remains legally valid. However, if you have added insulation, a new boiler, or double glazing, the old EPC won't reflect these, which could make your property less attractive to tenants or result in a lower-than-deserved rating.

Do I need an EPC for a House in Multiple Occupation (HMO)?

If you rent out the entire house on a single tenancy, you need one EPC for the building. If you rent out individual rooms, you generally only need an EPC if the building as a whole was required to have one when it was sold or let previously.

How can I quickly improve my rating before the assessment?

The easiest "quick wins" include replacing all lightbulbs with LEDs, ensuring the loft insulation is at least 270mm deep, and fitting a jacket to your hot water cylinder if it isn't pre-insulated.
