Help to install correctly

To help answer questions about the water fittings regulations in England, Wales and Northern Ireland, byelaws in Scotland, water undertakers and Water Regs UK publish general information and other tools on a range of topics. 

There are also publications giving installation specific information, which is sometimes referred to ‘workmanlike manner’. These include  Approved Installation Methods (AIMs), procedures approved by the water undertakers and British Standards (or their equivalent national specification), setting out installation specifications, such BS EN 806 and BS 1710. 

Water undertakers are always happy to assist those installing water fittings in their area with questions about specific installations. 

Please note:

The latest available edition or version of guidance or specifications should always be used. 

In respect of equivalence water undertaker retain absolute discretion in assessing whether a national specification provides an equivalent level of protection and performance to that specified in an appropriate British Standard. For information regarding the equivalence of a performance specification please contact your water undertaker.
