A Domestic Energy Performance Certificate (EPC) is a legal requirement for anyone selling or renting a residential property in England and Wales. As energy efficiency regulations tighten in 2026, homeowners, landlords, and agents must fully understand the EPC process, validity period, and legal obligations to remain compliant and avoid penalties.
This guide explains everything you need to know about domestic EPCs in 2026, including how assessments work, how long certificates last, and what the law requires.
What Is a Domestic EPC?
A Domestic EPC is an official document that shows how energy-efficient a residential property is. It provides:
An energy efficiency rating from A (most efficient) to G (least efficient)
Estimated energy costs for heating, lighting, and hot water
Recommended improvements to increase efficiency and reduce bills
The certificate is produced by an accredited EPC assessor and registered on the national EPC register.

Step 2: Property Inspection
The EPC assessment is non-intrusive and typically takes 30–90 minutes, depending on the size and layout of the property.
The assessor records:
Property size and floor area
Wall construction (solid or cavity)
Roof and loft insulation (where visible)
Window glazing type
Heating and hot water systems
Fixed lighting efficiency
Photographic evidence may be taken for audit and compliance purposes.
Step 3: Energy Calculation
The collected data is entered into government-approved EPC software (RdSAP), which calculates:
Energy efficiency rating (A–G)
Environmental impact rating
Estimated annual energy costs
Step 4: EPC Report Issued
Once complete, the EPC is:
Uploaded to the national EPC register
Issued digitally to the property owner or agent
Valid for use immediately
Most EPCs are delivered within 24–48 hours of the inspection.

How Long Is a Domestic EPC Valid?
A Domestic EPC is valid for 10 years from the date of issue.
You may need a new EPC if:
The existing certificate expires
Major energy-related improvements are made
You sell or rent the property without a valid EPC
Although not legally required, updating your EPC after improvements can significantly improve your rating and market appeal.
