Water Fittings Regulations

The Water Supply (Water Fittings) Regulations 1999 help keep your water safe and clean.

About the Regulations

The Water Fittings Regulations are national standards to help ensure the design, installation, and maintenance of plumbing systems, water fittings, and water-using appliances comply.

These regulations are in place to prevent waste, misuse, excessive consumption, inaccurate measurement, and most importantly, contamination, to protect the quality of your drinking water. As your water supplier, we are legally required to enforce these regulations and are committed to doing so consistently across our service area.

Where the Regulations apply

The Regulations cover all plumbing systems, water fittings, and water-using equipment in any premises connected to the public mains drinking water supply.

As an owner, occupier, or installer of plumbing systems and water fittings, you have a legal duty to ensure everything meets these Regulations.

Notification

You may need to provide advance notice of any planned plumbing work. This means architects, building developers, and installers must adhere to the Regulations on behalf of future owners or occupiers.

For more information, please read our Regulation 5 Notification.
