Energy Performance Certificates (EPCs) are required for both domestic and commercial properties in England and Wales, but the two types have significant differences. Understanding them helps property owners, landlords, and developers stay compliant and make informed decisions.
1. Purpose
Domestic EPC:
Measures the energy efficiency of homes and flats.
Helps buyers and tenants understand running costs.
Required when selling or renting residential properties.
Commercial EPC:
Measures the energy efficiency of non-domestic buildings (offices, shops, warehouses, schools, etc.).
Helps landlords and tenants understand energy costs, compliance, and sustainability.
Required when selling, renting, or constructing commercial buildings.

2. Assessment Method
| Feature | Domestic EPC | Commercial EPC |
|---|---|---|
| Assessment type | RdSAP (Reduced Data Standard Assessment Procedure) | SBEM (Simplified Building Energy Model) |
| Data collection | Mostly inspection-based | Plans, measurements, and complex modelling |
| Energy use | Residential energy usage | Heating, cooling, lighting, and operational systems |
| Survey duration | 1–2 hours | Can take several hours, depending on size and complexity |
3. Validity
Both Domestic and Commercial EPCs are valid for 10 years.
Domestic EPCs focus on typical household energy use; commercial EPCs consider energy use patterns of tenants and equipment.
4. Minimum Legal Requirements
Domestic:
No minimum rating required to sell, but must have a valid EPC.
Minimum rating (E) required for rental properties under MEES regulations.
Commercial:
Minimum rating of E required to lease under MEES.
F or G rated commercial properties cannot legally be rented unless an exemption applies.

6. Key Takeaways
Domestic EPCs = residential, simpler, inspection-based, no minimum for sale.
Commercial EPCs = non-domestic, complex modelling, minimum rating E for letting, legal penalties for non-compliance.
Both require valid certificates before marketing or leasing.
