Main changes;Introduction to amendments


The current edition of Part E in Schedule 1 to the Building Regulations 2000 (as amended) came into force on 1 July 2003. At the same time a new regulation 20A was introduced into the Building Regulations 2000, and a new regulation 12A was introduced into the Building (Approved Inspector etc) Regulations 2000. Regulations 20A and 12A introduced pre-completion testing for sound insulation as a means of demonstrating compliance. Pre-completion testing has applied to rooms for residential purposes, houses and flats formed by conversion of other buildings since 1 July 2003, and it will apply to new houses and flats from 1 July 2004. Also, from 1 July 2004, use of robust details in new houses and flats will be accepted as an alternative to testing.


Robust details are high performance separating wall and floor constructions (with associated construction details) that are expected to be sufficiently reliable not to need the check provided by pre-completion testing.


The introduction of robust details has necessitated the amendment of regulations 20A and 12A. The amendments have been made by the Building (Amendment) Regulations 2004 and the Building (Approved Inspector etc) (Amendment) Regulations 2004. Regulations 20A and 12A are reproduced in Approved Document E, 2003 Edition; and so amendments to that Approved Document are needed to pick-up the changes.


Section 0 of Approved Document E, 2003 Edition, has also been amended to explain the use of robust details.
