Regulation 31(12) 1 of the Water Supply (Water Quality) Regulations 2016 (as amended) [2018 in Wales] requires that a list of all the substances and products approved or refused under Regulation 31(4)(a) 2 and all approvals revoked or modified, shall be published, at least once a year. This list is now subject to regular updates and the latest version is available from this website. The list applies throughout the United Kingdom and any product that is listed on it can be used anywhere in the UK.
The Scottish Government also publishes a link to this website. This can be found on their website: http://www.gov.scot/Topics/Environment/Water/17670/approvals , as do Northern Ireland, and their link is: https://www.daera-ni.gov.uk/articles/duties-drinking-water-inspectorate-dwi#toc-4
- Printed copies - if you have printed a copy of this list, please ensure that you refer to the latest issue of the list on this webpage.
- Water treatment chemicals and filtering materials - products fully conforming to an appropriate BS EN Standard do not need an approval under Regulation 31(4)(a)2. Annex 2, Sections 2.1 & 2.2 of the list give details of water treatment chemicals and filtering materials which are currently covered by BS EN Standards, together with national conditions of use.
- Construction products – many of these products are covered by published BS EN standards, e.g. pipes and associated fittings - BS EN ISO 15874 to 15877 (Plastic piping systems for hot and cold water installations). Whilst these standards address general fitness for purpose issues, they do not adequately cover the suitability of the products for use with drinking water. Therefore, in all cases, approval of such products is required under Regulation 31 3.
