A unique reference directory of fittings, materials and appliances approved for their compliance with the UK plumbing regulations by the UK Water Suppliers, using the performance requirements set out by the Secretary of State at the Department for Environment, Food and Rural Affairs.
The popular Water Fittings and Materials Directory used throughout the UK water industry is now provided as an on-line, searchable database for which no subscription is necessary. The database is updated regularly so that the latest information is readily available to users.

Water fittings or appliances with WRAS Approved Product status have been assessed and approved by representatives of the UK Water Suppliers themselves – the same authorities which have the legal duty to enforce the regulations and make day-to-day decisions about the acceptability of fittings. Where an appropriate WRAS Approved water fitting or appliance is installed in accordance with any installations conditions, it should meet the requirements of Regulation (Byelaw) 4 for being “of an appropriate quality and standard”.

The WATER REGULATIONS ADVISORY SCHEME Ltd is funded by all the UK Water Suppliers and is operated independently of water fittings test laboratories. The Scheme employs its own staff to administer the WRAS Approvals process from its offices in South Wales. WRAS also publicises and promotes consistent interpretation of the Water Supply (Water Fittings) Regulations in England, Wales and Northern Ireland and the Scottish Water Byelaws.
