# Energy Performance Certificate Accreditation

An Energy Performance Certificate (EPC) must be produced by a qualified domestic or non-domestic energy assessor registered with one of the UK's approved bodies. The main regulatory schemes are the Scheme Administrator Approval bodies, which include NHER, Elmhurst, QUEST, BRE, and others. These bodies ensure assessors meet competency standards set by the Department for Levelling Up, Housing and Communities (DLUHC) and comply with strict qualification requirements, including relevant qualifications such as the Level 3 NVQ in Energy-Related Professions or equivalent. Different schemes may have slightly different names and structures, but all approved bodies operate within the same regulatory framework to maintain consistency and professionalism across the sector. Understanding which scheme your assessor is registered with helps you verify their legitimacy and ensures the certificate will be legally valid.

To verify a provider's credentials, you can check the NHER, Elmhurst, QUEST, or BRE registers directly online—most bodies maintain searchable databases where you can enter an assessor's name or reference number to confirm they are actively registered and in good standing. You should also ask the assessor directly which scheme they are registered with and request their registration number. It matters because only certificates issued by registered assessors are legally recognised for property sales, lettings, and construction project compliance. An unregistered assessor's certificate will be worthless and could expose you to legal liability, particularly if you're selling or letting a property. Additionally, registered assessors are subject to audits, complaints procedures, and professional standards, giving you recourse if the service is poor or negligent.

Accredited assessors typically charge between £60 and £150 for a domestic EPC, depending on region, property size, and complexity, whereas unaccredited or informal providers might quote significantly less.

Common questions
Energy Performance Certificate (EPC) — frequently asked questions
How much does an Energy Performance Certificate cost in the UK?
EPC costs typically range from £35 to £120 depending on property size and assessor location. Smaller properties cost less, whilst large houses or commercial buildings incur higher fees. Some estate agents offer free certificates when selling through them. Always request quotes from multiple certified assessors to compare prices.
What factors affect the price of an Energy Performance Certificate?
EPC costs depend on property size, location within the UK, building type (domestic vs commercial), assessor travel time, and property complexity including heating systems and insulation. Rural properties often cost more due to travel expenses. Listed buildings and period properties may require specialist assessment, increasing fees.
What does an Energy Performance Certificate service include?
An EPC includes a property inspection, assessment of heating, insulation, ventilation, and lighting systems, and a detailed energy efficiency rating from A to G. The certificate provides recommendations for improvements, estimated annual energy costs, and environmental impact ratings. Valid for ten years once issued.
What's the difference between a Standard Assessment Procedure and a Reduced Data Standard Assessment Procedure EPC?
Standard Assessment Procedure conducts full property inspections, whilst Reduced Data SAP uses property specifications without viewing all details. SAP provides more accurate results for detailed planning, whereas Reduced Data SAP is quicker and cheaper for lettings. Both are legally acceptable, though SAP is typically preferred by professionals.
What qualifications should an Energy Performance Certificate assessor have?
EPCs must be conducted by assessors registered with NHER, Landmark, or BRE accredited schemes. Verify they hold current professional credentials, valid insurance, and CIBSE accreditation where applicable. Check their registration status on the scheme's official website. Always request proof of qualification before booking.
How long does it take to get an Energy Performance Certificate after booking?
Most EPC assessments complete within 30-60 minutes on-site. Your certificate arrives within three to five working days via email. Express services may deliver within 24 hours for additional fees. Planning ahead for sales or lettings ensures certificates are ready before marketing your property.
Do I need a certified professional to conduct an Energy Performance Certificate?
Yes, EPCs are legally regulated in the UK and must be conducted by accredited assessors registered with approved schemes. Self-certification is illegal; only qualified professionals can produce valid certificates. Non-compliant certificates may result in trading standards fines. Always hire certified assessors from recognised bodies.
