Commercial EPC's
Domestic EPC's

What are Commercial EPC's?

Commercial EPCs enable potential buyers, tenants or building occupiers to make an informed decision on the energy performance of a building as part of their investment

EPCs are now required, from 1st January 2009, for all “conditioned” commercial properties more than 50sq metres when they are sold, let, modified (building fabric or services) or constructed.

A “conditioned” property is one with a roof and walls which uses energy to condition the indoor climate, i.e. some levels of heating, mechanical ventilation or cooling.

What buildings are exempt?

Only the following buildings do not require an EPC

1) Places of worship

2) Stand alone buildings of less than 50sq metres.

3) Particular buildings with a low energy demand (e.g. barns and other agricultural buildings)

4) Temporary buildings with a planned time of use of two years or less

5) Buildings due to be shortly demolished

Penalties for non-compliance

Failure to produce an EPC can result in a fine of 12.5% of the rateable value of the building up to a maximum of £5,000, and additionally the EPC must be obtained. Enforcement is carried out by local Trading Standards Departments.

What will the Assessor be looking at in the building?

The Energy Assessor needs to map out and understand the internal layout of the building and for what purpose each part is designed for.

They will be surveying and gathering data on all of the following in order to produce the EPC;

1) The construction of the fabric of the building and the thermal efficiency of the materials used in the roofs, walls, floors, and windows and doors

2) The dimensions of the individual spaces or zones in the building either from existing floor plans or, as measured including window areas

3) The activities conducted within the zones, for example office space, retail space, storage, kitchen, staff rooms etc

4) The heating and ventilation services within each individual zone including the type of system, the system controls, metering etc

5) The specific lighting and controls within each zone

It would be extremely useful if you could supply as much information on the property as possible, preferably in advance of the survey inspection

In particular, any information you can supply such as construction drawings/floor plans and information on the heating systems will save considerable time and cost.

Validity of Certificates

Domestic EPCs are valid for 10 years for rented properties and for three years as part of a HIP for residential sales. Non-domestic EPC's (Commercial EPC's) for sales or lettings are valid for 10 years.

If improvements have been carried out during this period it may be worth renewing the EPC, which can be arranged at a considerable discount, because an improved rating will make the property much more attractive to potential tenants or buyers.

More information can be found in the document A Guide to Energy Performance Certificates for the Construction, Sale and Let of Non Dwellings.
