In order to protect your water supply from contamination, it is important that your fixtures and fittings are correctly installed and in a good state of repair. The purpose of these Regulations is to protect your drinking water supply from contamination, and prevent inefficient use of water or incorrect measurement of it. The Regulations apply in England and Wales to all plumbing systems, water fittings and equipment supplied, or to be supplied, with water from the public water supply. This applies to systems in all types of premises.
Your water wholesale supplier is responsible to the Government for the enforcement of the Regulations and they have the right to visit your premises and carry out checks to ensure your water fittings comply.
How do the water regulations affect my business?
- Your plumbing system must be installed and maintained to comply with the regulations
- You must prevent contamination of drinking water
- You must give advanced notification of plumbing work
- We advise you to use an approved plumbing contractor.
What's the risk to my business?
If your business has plumbing that contravenes the Water Regulations it faces risks that could impact on its financial and reputational performance.
It is the legal duty of your business to comply with the Regulations. Due to the potential risk posed to public health via backflow, the Government have legislated that plumbing systems must be properly designed, installed, operated, and maintained to meet the requirements of the Regulations. It is a criminal offence to breach the Regulations and offenders may face prosecution. Where breaches of the Regulations are found, we have a legal duty to ensure they are remedied. In emergencies, we may have to disconnect the water supply to the premises immediately.
The Regulations are designed to protect the public health of both employees and the general public by preventing contamination via backflow.

Why do I need an approved contractor?
A WaterSafe approved contractor will accept legal liability for any work they undertake. They will provide your business with a compliance certificate upon completion of works. This certificate gives your business the peace of mind that, should the work not meet the requirements of the Water Regulations, you will be legally protected from further action. The Approved Contractor would have to put the work right at their own cost.
