If you believe an EPC contains an error, first review the certificate details, address, property information and evidence used. You may contact the assessor or accreditation scheme for the correct complaints or review process. The rating can only be changed where the approved process supports a correction or new assessment.

An EPC assesses energy performance using approved methodology. It is not a structural survey, condition survey, damp survey, valuation, gas safety check, electrical safety check or retrofit assessment. Separate inspections may be needed for those purposes.

Some energy efficiency schemes may use EPC rating, property type, income, tenure, heating system, council tax band or other eligibility checks. An EPC does not guarantee funding approval. Scheme rules, survey findings and eligibility criteria must be checked separately.

Residential EPCs apply to domestic properties such as houses and flats and are usually carried out by domestic energy assessors. Commercial EPCs apply to non-domestic premises such as shops, offices and warehouses and usually require a non-domestic energy assessor. The correct EPC type depends on property use and transaction type.

A residential EPC is normally valid for 10 years unless a newer EPC is produced and lodged for the same property. A new EPC may be needed if the current certificate has expired or an updated rating is required.

No. The final EPC rating depends on the property, evidence available, approved methodology and assessor findings. HSSE Solutions cannot guarantee a specific EPC band before assessment and lodgement.

No. EPC recommendations may indicate possible improvements, but actual bills depend on property condition, installed measures, energy tariffs, occupancy, heating use, ventilation and occupant behaviour.
