Water Regulations Domestic Installation – TAPS 4 Certificate Required

The Water Supply (Water Fittings) Regulations 1999, set requirements for the design, installation and maintenance of plumbing systems and water fittings.  The Department of Environment, Food and Rural Affairs (Defra) allows organisations such as Thames Water to run an approval scheme, which enables plumbers or contractors to self-certificate their own work.  This negates the need for a separate regulations inspection to be carried out by water companies who have a duty to enforce the regulations.

There are currently four types of certificates:



For internal work in new properties and can be only issued by an approved plumber.


For internal work in existing properties that require no new connections or upgrades of supply size from Thames Water. This can only be issued by an approved plumber.


For underground supply pipes from an outside stop valve or boundary to an inside stop valve. Either an approved plumber or underground worker can issue this.


For notification work. This is issued by an approved plumber and is followed up by a TAPS 4 certificate once the work is complete.
