    MAIN CHANGES MADE TO THE 2003 EDITION BY INCORPORATING AMENDMENTS 2004†

    This edition of Approved Document E, Resistance to the passage of sound, supersedes the original 2003 edition by incorporating the changes made by Amendments 2004 (issued in June 2004) to Approved Document E 2003. Minor corrections and clarifications have also been made, but there is no new information. 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 to new houses and flats from 1 July 2004. Also, from 1 July 2004, use of robust details in new houses and flats has been accepted as an alternative to pre-completion 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 were reproduced in Approved Document E, original 2003 Edition; and so amended versions have been included in this edition. Section 0 of Approved Document E, original 2003 Edition, has been amended in this edition to explain the use of robust details and Annex E has been added for the same reason. The original 2003 edition of Part E introduced a new class of dwelling known as a room for residential purposes, which covers hostel types of accommodation and hotel rooms. The expression ‘room for residential purposes’ is defined in Regulation 2 of the Building Regulations 2000 and the definition was reproduced in Approved Document E, 2003. However, the definition has been interpreted in different ways by building control bodies, particularly in respect of student halls of residence, and it has, therefore, been clarified, by means of the Building (Amendment) Regulations 2004, and the clarified version has been reproduced in this edition.

    MAIN CHANGES MADE BY THE 2010 AMENDMENTS The main changes reflect the Building Regulations 2010 and Building (Approved Inspectors etc.) Regulations 2010. There were no changes to Part E of Schedule 1 to the Building Regulations 2010. MAIN CHANGES MADE BY THE 2013 AMENDMENTS The main changes, which apply only to England*, were to materials and workmanship. There were no changes to Part E of Schedule 1 to the Building Regulations 2010. CHANGE MADE BY THE 2015 AMENDMENT The change, which applies only to England*, from 6 April 2015, is an update of the reference to standards for schools.
