Water regulations Reg 5 notification

Regulation 5 - notification

The Water Supply (Water Fittings) Regulations, or Byelaws in Scotland, require, for most types of work the designer, installer, owner or occupier to obtain the local water supplier’s consent before starting any work.

This means sending to your local water supplier a Notice and other information relating to the proposed work.

Water suppliers are required by the Regulations and Byelaws not to withhold consent unreasonably, and allow consent to be granted subject to conditions, which must be followed.

If consent is not given within the ten working days, then the Regulations and Byelaws deem the water suppliers’ consent to have been granted. This does not alter the obligation upon the, designer, installer and owner or occupier to see that the Water Supply (Water Fittings) Regulations, or Byelaws in Scotland, are fully met.
