Non-Domestic Energy Performance Certificates are required for commercial premises from 1st October 2008 & it is the responsibility of Sellers and Prospective Landlords to make the EPC available to prospective purchasers and tenants respectively.

Multi- tenanted buildings are subject to certification according to rules depending on the configuration of the heating and conditioning systems. Generally in cases where there is a common heating system they can either be assessed as a whole, or independently, whereas buildings with units having independent heating systems in each unit will have to be provided with separate EPC's.

Timetable for implementation of non-domestic EPC's is as follows:

• 6th April 2008 - > 10,000 m2  require an EPC at the point of sale or rent (Delayed to 1st October 2008)
  
• 1st July  2008  -  > 2,500 m2 require an EPC at the point of sale or rent (Delayed to 1st October 2008)
• 1st October 2008 - > non-dwellings > 50 m2 require an EPC at the point of sale or rent

Transitional arrangements now provide that where non-dwellings of floor area >10,000 m2 were already on the market prior to 1st April 2008, they need to have an EPC by 1st October 2008. If they are rented or sold before then, the EPC must be provided as soon as is reasonably practicable. Similar provisions will apply to non-dwellings of floor area >2,500 m2 on the market before July 1st 2008
