On the 1st October 2015, as part of the Housing Standards Review, Government aimed to consolidate legislation into The Building Regulations from standards previously applied through the Planning process including Access and Water Efficiency.
The Local Planning Authority (LPA) can impose Optional Requirements when granting consent for residential schemes with regard to M4(2), M4(3) and G2 of the revised requirements of The Building Regulations which came into force on 1st October 2015.
The applicant is required to declare whether the LPA has imposed any Optional Requirements when making an application to the Building Control Body (our application form provides a simple ‘tick-box’ facility for this purpose) and it is for the Building Control Body to ensure these higher standards are met.
Part M Access to and use of buildings – Volume 1 Dwellings
Main changes in the 2015 editions
This volume of this approved document supports requirements M4(1), M4(2) and M4(3) of Schedule 1 of the Building Regulations 2010. It takes effect on 1 October 2016 for use in England. The 2004 edition of Approved Document M with 2010 and 2013 amendments will continye to apply to work started before 1 October 2016 or to work subject to a building notice, full plans application or initial notice submitted before that date.
The main changes are:
- Volume 1: Dwellings
- Volume 2: Building other than dwellings
Requirement M4 ‘Sanitary conveniences in dwellings’ has been replaced by new requirements:
- M4(1) Category 1: Visible dwellings
- M4(2) Category 2: Accessible and adaptable dwellings
- M4(3) Category 3: Wheelchair user dwellings
Regulation M4(1) is mandatory for all new dwellings unless one of the optional requirements (m4(2) or M4(3) applies.
M4(2) and M4(3) require increased levels of accessibility and you advised to contact our Technical Team to discuss compliance with these requirements at an early stage in the design process.
Part G 2 Water Efficiency
The LPA can impose an Optional Requirement to reduce the potential water use from 125 litres per person/day to 110 litres
The revised guidance in the Approved Document, further amended in 2016, is summarised as:
2015 Edition
This approved document supports Regulation 36 and Part G of Schedule 1 to the Building Regulations 2010. It takes effect on 1 October 2015 for use in England. The 2010 edition, as amended, will continue to apply to work started before 1 October 2015 or work subject to a building notice, full plans application or initial notice submitted before that date.
The mains changes are:
Introduction of an optional requirement for tighter water efficiency in Regulation 36 (section G2).
Introduction of a fittings approach as an alternative to using the water efficiency calculated (section G2).
Inclusion of the water efficiency calculator methodology into this approved document, with minor alterations resulting from European efficiency labelling and consequential amendments resulting from removal of references to the Code for Sustainable Homes (Appendix A).
The annex listing the relevant competent person self-certification schemes has been deleted.
Change made by the 2016 amendments
The change, made by Section G2, requires the water efficiency calculator to be completed for new dwellings where a shower will not be provided.
