A commercial Energy Performance Certificate is a legal requirement whenever a non-domestic property is sold or let. Like a domestic EPC, it rates the building from A to G, but the assessment uses different methodology. SBEM (Simplified Building Energy Model) rather than RdSAP is used, and it focuses on the building's fixed services, construction and asset energy performance. The certificate is valid for ten years and must be lodged on the non-domestic EPC register before marketing begins. Commercial EPC work is underserved in North Wales, with most assessors focused on domestic properties. We carry out commercial assessments regularly and can advise on the right certificate type for your property before you book.
Any commercial property marketed for sale or let in England and Wales must have a valid EPC before it goes on the market. This is a legal requirement that applies to offices, retail units, industrial premises, warehouses and mixed-use buildings. You cannot exchange contracts or grant a lease without a valid EPC in place. Marketing without one can attract a fixed penalty from the local authority.
Holiday lets that are commercially operated require a commercial EPC in most cases. Properties advertised through booking platforms, letting agents or marketed as tourist accommodation generally fall into the commercial category. This is a growing segment in North Wales: coastal properties, Snowdonia retreats and rural accommodation. We assess these regularly and can advise on whether your property needs a domestic or commercial certificate before you book anything.
When a new lease is granted or an existing one renewed on a commercial property, a valid EPC must be in place. Landlords are responsible for providing this, not tenants. If your current certificate is approaching ten years old, renew it before new tenants move in so the information is current.
Commercial properties being let must meet Minimum Energy Efficiency Standards. The current minimum rating is E, and this applies to new leases and existing leases. You cannot legally let a commercial property rated F or G without a valid exemption. Failure to comply can result in significant financial penalties. Getting a current EPC tells you exactly where your property stands before entering into any letting arrangements.

Fixed quote before you book. No surprises on the day. No VAT charged. Travel within approximately 10 miles of Deganwy is included. Properties further afield may carry a small additional travel fee, confirmed in the quote. Request a quote and we'll come back to you the same working day.
Tell us the property type, approximate size and location. We will confirm the price before anything is booked. There is no obligation at this stage. We typically respond the same working day.
We visit the property and carry out the assessment using accredited SBEM software. Larger or more complex properties take longer. We will give you a realistic time estimate when you book so you can plan access accordingly.
The commercial EPC is lodged on the Non-Domestic Energy Performance Certificate register. You receive the certificate and reference number by email, typically within 24 hours and always within 48 hours of the site visit.
We'll come back to you the same working day with a fixed price.
