In respect of non-dwellings, the key requirements of the Energy Performance of Buildings (Certificates and Inspections) (England and Wales) Regulations 2007 are summarised below.

Production Of Energy Performance Certificates

Where a building is to be sold or rented out and a plausible prospective buyer or tenant:

  • requests any information about the building from the seller/landlord or his agent for the purpose of deciding whether to buy or rent the building;
  • makes a request to view the building for the purpose of deciding whether to buy or rent the building; or
  • makes an offer, whether oral or written, to buy or rent the building,

the seller/landlord must make available free of charge a valid Energy Performance Certificate ("EPC") to the prospective buyer or tenant. 

In addition, when a building is constructed or modified, a valid EPC has to be provided to the new owner by the person carrying out the work.

EPCs have to conform to a particular format that is set out in the Regulations. They are valid for a maximum of 10 years unless superseded in the meantime by a fresh EPC. Where handed over, they should usually be accompanied by a report containing recommendations for the improvement of the energy performance of the building in question.

The new rules on EPCs come into force as follows:

  • From 6 April 2008: EPCs required on construction, modification, sale and rental of non-dwellings of more than 10,000m²
  • From 1 July 2008: EPCs required on construction, modification, sale and rental of non-dwellings of more than 2,500m²
  • From 1 October 2008: EPCs required on construction, modification, sale and rental of all other non-dwellings.

There are limited exceptions to the new rules on EPCs. In particular, they do not have to be made available in respect of:

  • places of worship;
  • temporary buildings with a planned time of use of two years or less, industrial sites, workshops and non-residential agricultural buildings with low energy demand; or
  • stand-alone buildings with a total useful floor area of less than 50m² which are not dwellings.

In addition, EPCs do not have to be given or made available to a prospective buyer or tenant in respect of buildings that will be or are likely to be demolished.

Display Energy Certificates

There are further requirements in respect of buildings with a total useful floor area over 1,000m² that are: (a) occupied by public authorities; or (b) occupied by institutions providing public services and are frequently visited by the public.

On and after 1 October 2008, every occupier of any such building must:

  • have in its possession or control at all times a valid advisory report containing recommendations for improvement of energy performance; and
  • display at all times a valid Display Energy Certificate ("DEC") in a prominent place clearly visible to the public.

Display energy certificates and advisory reports are valid for 12 months and seven years respectively.

Air Conditioning Systems

Persons in control of air conditioning systems  with an effective rated output of more than 12kW must ensure that the system is inspected at regular intervals not exceeding every five years.

In the case of systems put into service after 1 January 2008, the first inspection must take place within five years of it being put into service. In the case of systems put into service before 1 January 2008, the first inspection must take place before:

  • 4 January 2009 (for systems with an effective rated output of more than 250kW)
  • 4 January 2011 (for systems with an effective rated output of between 12kW and 250kW).
