Current Legislation

Domestic and Non-Domestic Buildings

All properties, whether domestic homes or commercial buildings are required to have an Energy Performance Certificate (EPC) when constructed, sold or let.The purpose of the legislation is to make energy efficiency of buildings transparent through the provision of an EPC, showing the energy rating of a building and recommendations on how to improve its efficiency.

From April 2018 The Energy Efficiency (Private Rented Property)(England and Wales) Regulations 2015 state that landords must ensure that properties they rent in England and Wales have a minimum EPC rating of E, before they can grant a tenancy to new or existing tenants.  These requirements apply to both private rented domestic and non domestic properties.

Public Buildings

A DEC and Recommendation Report are required for buildings with a total useful floor area over 250m2 that are occupied in whole or part by public authorities and frequently visited by the public. DECs for buildings of over 1,000m2 must be renewed every 12 months. DECs for buildings of 250 – 1,000m2 must be renewed every 10 years.

Air Conditioning in Buildings

All air conditioning systems with an effective rated output of more than

12kw must be regularly inspected by an energy assessor. The inspections must be no more than five years apart.

The regulations require the first inspection of the affected air conditioning systems to be carried out as follows:

  • for all systems first put into service on or after 1 January 2008, the first inspection must have taken place within five years of the date when the system was first put into service
  • for other air conditioning systems, where the effective rated output is more than 250kW the first inspection must have taken place by 4 January 2009
  • for other air conditioning systems, where the effective rated output is more than 12kW the first inspection must have taken place by 4 January 2011

Systems requiring an air conditioning inspection

Only air conditioning systems with an effective rated output of more than 12kW are affected by these regulations. This will include systems consisting of individual units which are less than 12kW but whose combined effective rated output is more than 12kW.

The effective rated output is the maximum calorific output in kW stated by the manufacturer of the system as deliverable during continuous operation while complying with the useful efficiency indicated by the manufacturer.

One or more air conditioning units within a building controlled by a single person are considered to comprise a single air conditioning system for the purposes of the regulations.
