Commercial EPC and MEES: what to check before letting a business property
A practical order of checks for a landlord marketing a shop, office, warehouse or other non-domestic premises.
Confirm what is being let
A commercial Energy Performance Certificate assesses a non-domestic building or a separately usable part of one. In a multi-let office, retail unit or mixed-use building, the certificate needs to cover the accommodation being sold or let. A certificate for an entire building is not automatically the right document for a separately serviced unit. Gather the lease plan, floor area, use of the space and details of its heating, ventilation and air-conditioning before seeking a quote. The government's non-domestic EPC guidance explains how the boundary of an assessment is determined.
Check the certificate, then the rating
Search the official certificate register first. A non-domestic EPC is normally valid for 10 years and can be reused within that period if it covers the property in question. When a building is constructed, sold or let, an EPC is generally required unless an exception applies. A valid certificate answers the documentation question; it does not by itself answer whether the property meets the minimum standard for a private letting.
Understand the current MEES position
For privately rented non-domestic property in England and Wales that is within the regulations, the current Minimum Energy Efficiency Standards generally require an EPC rating of at least E unless a valid exemption is registered. The rules apply to new, renewed and continuing relevant tenancies. Scope and exceptions matter, including whether the property is legally required to have an EPC and the length of the tenancy. An F or G rating calls for a separate compliance review; commissioning another EPC without improvements will not itself improve the building. Read the government's non-domestic MEES guidance before relying on an exemption or proposed future target.
Give the assessor useful evidence
Plans, measured area, plant information and access to each relevant zone help establish an accurate scope. Ask whether you need an EPC for the whole building or the unit being marketed. Our commercial EPC service shows the information needed for a quote. If construction or major design work is still under way, the service directory also explains the separate SBEM calculation route.
