The Building Regulations 2010 set out the kinds of work that are exempt from the Regulations. NOTE: Some works
may however require Planning permission.
The Building Regulations are made up of procedural and technical provisions. Some works are exempt from the
whole of the Regulations, others are only exempt from certain aspects.
In respect of technical requirements the exemptions are judged by two approaches:
(1) Parts A to K, M and P are judged against seven classes set out in Schedule 2 of the Building Regulations.
(see table below)
(2) Part L is judged against criteria set set out in Regulation 21 of the Building Regulations. (see overview below)
Regulation 21[a1] of the Building Regulations 2010, sets out the exemption criteria with regard to the Part L
(Conservation of fuel and power) requirements.
Broadly, the Part L requirements apply
to buildings, or extensions of such buildings (except those of Class 7 type
(see above)), or the carrying out of any work to or in connection of any such building or extension where the building:
(i) is a roofed construction having walls; and
(ii) uses energy to condition the indoor climate
However, the Part L requirements do not apply to
buildings which fall into the following categories:
(i) Certain buildings which are listed, in conservation areas or are included in the schedule of monuments
(ii) where compliance with the energy efficiency requirements would unacceptably alter their character or
(iii) Buildings which are used primarily or solely as places of worship
(iv) Temporary buildings with a planned time of use of 2 years or less, with low energy demand
(v) Industrial sites, workshops and non-residential agricultural buildings with low energy demand
(vi) Stand-alone buildings other than dwellings with a total useful floor area of less than 50m²
