Water fittings regulations

The Water Supply (Water Fittings) Regulations 1999.

Severn Trent Water prides itself on supplying the highest quality water to our customers and we are committed to maintain these standards which are rigorously monitored by our Regulators.

We must also ensure that others follow the rules on connecting, using and maintaining pipes and water fittings inside homes and businesses.

These rules are called the Water Supply (Water Fittings) Regulations 1999 (the Regulations) and are designed to stop the waste, misuse, undue consumption, erroneous measurement and more importantly contamination of the drinking water supply.

It is a legal requirement for us to enforce the Regulations and to ensure that we adopt a consistent approach on enforcing these Regulations within our area of supply.


Our Aim

We aim to carry out an inspection programme based on criteria concerning the risk posed by the installation, type of premise and previous inspections.    


We have a legal obligation to enforce the Regulations which are carried out by a team of qualified Water Fittings Regulations Technicians.  Our inspection activities are undertaken on a risk based approach taking into account the following.  This list is not exhaustive: 

  • High Risk Premises
  • Heavy Industrial, Commercial & Agricultural
  • Public Buildings
  • Education, Medical, Sport Centres, Hostelries & Exhibition Halls
  • Private Water Supplies
  • Water abstracted from an alternative source other than water provided by the water undertaker, i.e. Borehole, River & Spring
  • New Connections to the public water supply E.g. Domestic or Non-Domestic premises

We will also undertake reactive inspections at premises where there is a risk posed to public health.
