An Energy Performance Certificate (EPC) rates how energy efficient your building is using grades from A to G (with 'A' the most efficient grade).
When you need an EPC
You must have an EPC if:
- you rent out or sell the premises
- a building under construction is finished
If you're renting or selling your premises, an existing EPC can be used where this is still valid. Otherwise a new EPC must be obtained. You can be fined up to £1,000 if you don't make an EPC available to any prospective buyer or tenant.
When you must display one
You must display an EPC by fixing it to your commercial building if all these apply:
- the total useful floor area is over 500 square meters (or over 250 square meters if occupied by a public authority)
- the building is frequently visited by the public
- an EPC has already been produced for the building's sale, rental or construction
How much it costs
The cost of an EPC will depend on the building being assessed. All EPCs are valid for 10 years.
