A local energy assessor has urged owners of commercial properties to ensure they obtain the correct documentation if they want to sell or let premises.

Stuart Bird, of the Shipley office of Countrywide Energy Assessors, says new research revealed many commercial property owners were unaware they will need an energy performance certificate if they put buildings on the market from January.

The requirement is part of Government moves to reduce energy consumption and tackle climate change.

Energy certificates have been required since April this year on sales and lettings of larger premises but from January they will be needed when any commercial property is put on the market.

The certificates can only be provided after an inspection of premises by qualified and accredited assessors. This includes the size, age and type of building, heating and air conditioning systems, and insulation levels.

Stuart Bird said: “We were surprised to find that many owners did not know about the need for an energy performance certificate or the looming deadline.

“We recommend that all owners with properties on the market act quickly to arrange certificates before January to comply with the new regulations. There are very few exceptions and large fines for non-compliance.”

Mr Bird said energy certificates were valid for ten years.
