Energy Performance Certificates (EPCs) are an essential part of property compliance in the UK. Whether you own a residential home or a commercial building, understanding the difference between Domestic EPCs and Commercial EPCs is important for legal compliance and property transactions.
Both certificates measure the energy efficiency of buildings, but they apply to different property types and involve different assessment methods.
What is a Domestic EPC?
A Domestic Energy Performance Certificate (EPC) applies to residential properties such as:
Houses
Flats and apartments
Bungalows
Residential conversions
Domestic EPCs provide a rating from A (most energy efficient) to G (least energy efficient) and show how energy efficient a home is.
The report includes:
Estimated energy costs
Carbon emissions
Energy efficiency recommendations
Potential future energy rating
Domestic EPCs are required when selling, renting, or building a home.

What is a Commercial EPC?
A Commercial EPC applies to non-domestic properties, including:
Offices
Shops and retail units
Restaurants and cafés
Warehouses
Hotels and industrial buildings
Commercial EPCs assess energy use based on building size, heating systems, lighting, and ventilation systems.
These certificates are required when a commercial property is:
Sold
Leased
Newly constructed

Key Differences Between Domestic and Commercial EPC
| Feature | Domestic EPC | Commercial EPC |
|---|---|---|
| Property Type | Residential homes | Business and non-domestic buildings |
| Examples | Houses, flats, apartments | Offices, shops, warehouses |
| Assessment Complexity | Simple inspection | More detailed analysis |
| Average Inspection Time | 30–40 minutes | 45 minutes to several hours |
| Typical Cost | From £34.99 | From £145 |
| Regulations | Residential property rules | Commercial building regulations |
Commercial EPCs usually require more detailed surveys because commercial buildings often have complex heating, lighting, and ventilation systems.
EPC Legal Requirements for Property Owners
UK regulations require property owners to obtain an EPC before marketing a property for sale or rent.
Landlords must also comply with Minimum Energy Efficiency Standards (MEES), which require most rental properties to achieve at least an EPC rating of E.
Failure to comply can result in financial penalties or restrictions on renting the property.
How Long Does an EPC Last?
Both Domestic and Commercial EPCs are valid for 10 years.
However, property owners may choose to obtain a new EPC sooner if:
Major renovations improve energy efficiency
Heating systems are upgraded
Insulation improvements are installed
What Happens During an EPC Assessment?
During an EPC inspection, the assessor evaluates:
Heating systems
Insulation levels
Windows and glazing
Hot water systems
Lighting efficiency
Building size and structure
The collected data is processed using government-approved EPC software, and the certificate is normally issued within 24 hours.

Which EPC Do You Need?
You need a Domestic EPC if the property is a home or residential unit.
You need a Commercial EPC if the building is used for business or commercial purposes.
Mixed-use buildings may sometimes require separate EPC certificates for residential and commercial sections.
