Coming into force 8th June 2018

The Welsh Ministers are designated for the purposes of section 2(2) of the European Communities Act 1972 in relation to the design and construction of buildings and in relation to services, fittings and equipment provided in or in connection with those buildings.
S.1. 2016/161.
1972 c. 68. Section 2(2) was amended by section 27 of the Legislative and Regulatory Reform Act 2006 (c. 51) and section 3 of, and Part 1 of the Schedule to, the European Union (Amendment) Act 2008 (c. 7).
The Welsh Ministers, in exercise of the powers conferred on them by section 2(2) of the European Communities Act 1972, and on the Secretary of State by sections 1, 1A, 2, 2A, 3, 16, 17, 34, 35, 47, 49, 50, 51, 51A, 52 and 54 of, and paragraphs 1, 2, 4, 4A, 6, 7, 8 and 10 of Schedule 1 to, and paragraphs 2 and 3 of Schedule 4 to, the Building Act 1984, and now exercisable by them,having consulted the Building Regulations Advisory Committee for Wales and such other bodies as appear to them to be representative of the issues concerned in accordance with section 14(7) of that Act make the following Regulations:
1984 c. 55. Section 1 was amended by section 1 of the Sustainable and Secure Buildings Act 2004 (c. 22) (“the 2004 Act”); sections 1A and 2A were inserted by sections 2 and 4 of the 2004 Act respectively; section 16 was amended by the Statute Law (Repeals) Act 1993 (c. 50), sections 47 and 52 were amended by S.I. 1996/1905 and section 8 of the 2004 Act; sections 50 and 51 were amended, and section 51A was inserted, by S.I. 1996/1905; Paragraph 4A was inserted into Schedule 1 by section 8 of the 2004 Act; paragraph 7 of Schedule 1 was amended by section 3 of the 2004 Act and by section 11 of the Climate Change and Sustainable Energy Act 2006 (c. 19); and paragraph 8 of Schedule 1 was amended by section 3 of the 2004 Act and section 40 of the Flood and Water Management Act 2010 (c. 29).
Functions conferred or imposed on the Secretary of State by or under the Building Act 1984 (“the 1984 Act”) were, so far as exercisable in relation to Wales, transferred to the Welsh Ministers by the Welsh Ministers (Transfer of Functions) (No. 2) Order 2009 (S.I. 2009/3019) (“the 2009 Order”) subject to articles 3 and 4 of that Order. Article 3(a) of the 2009 Order provided that functions were not transferred so far as they were exercisable in relation to an excepted energy building as defined by the Schedule to that Order. Section 54 of the Wales Act 2017 (c. 4) removed this exclusion by making the necessary provision for the transfer of functions under the 1984 Act for that category of buildings.
Section 14(7) was added by the 2009 Order.

EXPLANATORY NOTE
(This note is not part of the Regulations)
These Regulations amend the Building Regulations 2010 (“the Building Regulations”) and the Building (Approved Inspectors etc.) Regulations 2010 (“the Approved Inspectors Regulations”) in relation to excepted energy buildings in Wales.
Functions under the Building Act 1984 (“the 1984 Act”) to make building regulations and associated matters were transferred to the Welsh Ministers by the Welsh Ministers (Transfer of Functions) (No. 2) Order 2009 which came into force on 31 December 2011. An exclusion from the transfer was made in relation to “excepted energy buildings” which has the meaning given by the Schedule to that Order.
Amendments to the Building Regulations and the Approved Inspectors Regulations made by the Secretary of State from 31 December 2011 applied in relation to England and to excepted energy buildings in Wales. Amendments to those Regulations made by the Welsh Ministers from 31 December 2011 applied in relation to Wales other than to excepted energy buildings.
Section 54 of the Wales Act 2017 removes the exclusion in relation to excepted energy buildings by making the necessary provision for the transfer of functions under the 1984 Act for that category of buildings from 1 April 2018.
The effect of the amendments made by these Regulations is to bring provisions in the Building Regulations and Approved Inspectors Regulations in relation to excepted energy buildings in Wales in line with provisions applying to other buildings in Wales.
The Welsh Ministers’ Code of Practice on the carrying out of Regulatory Impact Assessments was considered in relation to these Regulations. As a result, it was not considered necessary to carry out a regulatory impact assessment as to the likely costs and benefits of complying with these Regulations.
