Book an EPC.

Domestic Energy Assessors (DEAs) provide the vital Energy Performance Certificate (EPC) required whenever a property is built, sold, or rented in the UK. This document gives prospective buyers or tenants an objective view of the property's energy costs and carbon footprint, rated from A (most efficient) to G (least efficient).

Beyond legal compliance, an EPC assessor identifies where heat is being lost and recommends specific improvements, such as insulation or heating upgrades. For homeowners looking to reduce energy bills or access government grants like the Boiler Upgrade Scheme, a professional assessment is the essential first step.

What to Expect When Hiring an EPC Assessor

A standard domestic energy assessment is a non-invasive visual inspection. The assessor will need access to every room in the house, including the loft and any basement areas.

• Initial Survey: The assessor will spend 30 to 60 minutes measuring the property's internal and external dimensions.
• Data Collection: They will inspect the heating system (boiler and controls), hot water cylinder, insulation levels, and glazing types.
• Evidence Gathering: Assessors are required to take photographs of key features, such as the loft insulation and the boiler’s data plate, as evidence for their accreditation body.
• Software Analysis: The data is entered into government-approved RdSAP (Reduced Data Standard Assessment Procedure) software to calculate the rating.
• Lodgement: Once complete, the certificate is lodged on the national EPC Register, and you will receive a digital copy or a link to the online record.

Why Hire a Professional?

In the UK, you cannot produce your own EPC. By law, the certificate must be produced by a qualified and accredited Domestic Energy Assessor to be valid for a property sale or let.

Hiring a professional ensures your property is assessed against the latest Part L Building Regulations. For landlords, this is particularly critical; under Minimum Energy Efficiency Standards (MEES), most domestic rental properties must have a rating of 'E' or higher to be legally let. A professional assessor can provide a "draft" EPC and advise on the most cost-effective ways to reach the required rating before the final certificate is lodged.

Typical Costs

EPC costs are generally flat fees based on the size and complexity of the property. Prices are not regulated by the government, so they can vary by region and the individual assessor’s travel distance.

Prices typically include the lodgement fee (the cost of registering the certificate on the central database). If you book through an estate agent, they may add a commission; booking a local independent assessor directly is usually the most cost-effective route.

How to Choose the Right EPC Assessor

When selecting an assessor, it is important to verify their credentials to ensure the certificate is legally binding and accurate.

• Check the EPC Register: Only use assessors listed on the official GOV.UK Find an Energy Assessor register.
• Accreditation Body: Ensure they belong to a recognised scheme such as Elmhurst, Quidos, or Stroma/Sava.
• Insurance: Confirm they hold valid Professional Indemnity and Public Liability insurance.
• Local Knowledge: A local assessor will understand common regional building types (such as Cornish units or specific stone wall constructions) which helps in accurate data entry.

Questions to ask before hiring:

• Are you a member of a government-approved accreditation scheme?
• Does the quote include the government lodgement fee?
• How soon after the visit will the certificate be available online?
• Can you provide a draft rating if the property is likely to fall below an 'E' rating?
