You are here : At Home > My Water > Water fittings regulations
Under the Water Supply (Water Fittings) Regulations 1999 it is the legal duty of the owner, occupier, installer or plumber to ensure the regulations are met and to notify us before any work begins. If the owner or occupier does not seek permission, then the duty rests with the installer or plumber. Failure to notify may result in legal action taken against you/your company.
These regulations do not apply where a property uses a private water supply and does not have a supply of water from a water company. However, it is good plumbing practice to follow the requirements of the Regulations.
The regulation applies from the point where the water enters the underground service pipe to the point where the water is used.
It applies to all properties supplied by mains water or a private supply using mains water as a backup from a water company. They do not apply where a property uses a private water supply and does not have a supply of water from a water company.
To notify us is free simply complete our online form.
You will need to attach:
We will contact you within 10 working days if we need to discuss your plans further. If you don’t hear from us in that time, you can assume it is all right to go ahead.
It is important your work complies with the regulations. If it does not, changes may need to be made at a later date.
Please note: You cannot start any works until you have permission, we would encourage you to apply in advance to allow us time to process your form.

The following types of work are covered by the Water Supply (Water Fittings) Regulations 1999. You must tell us about your plans and the fittings you will be using, Work should not begin until permission is granted and you must comply with any conditions set out by us.
Anyone who lives in or manages a home or business property and anyone who installs plumbing systems or water fittings, has a legal duty to meet the Water Supply (Water Fittings) Regulations, The owner, occupier, installer or plumber carrying out the work all have a responsibility to gain permission from us. If the owner or occupier of the property do not notify us, then the plumber or installer must do so.
Approved plumbers are able to carry out some types of plumbing work without prior notification, such as Extending or altering the water system on a non-household building. If the plumber is an Approved WaterSafe contractor or an approved WIAPS ground worker then they should issue a certificate to owner or occupier and the local water supplier that states the works has been carried out in line with the regulations. Please remember to ask your plumber for the certificate.
WIAPS is the largest of the seven UK Approved Contractors’ Schemes. WIAPS is administered by Water Regs UK on behalf of 14 of the UK Water Undertakers.
WaterSafe is the central body for approved plumbers, bringing together several accreditation schemes across the UK. You can find your nearest approved plumbing business using the postcode search on their website.
