Every WaterSafe approved plumbing business is required to hold public liability cover of at least £2 million and employers’ liability insurance where appropriate. By using an unrecognised plumber, customers may well be unprotected if the worst should happen.

WaterSafe approved plumbing businesses must also adhere to the WaterSafe code of conduct and customer commitments - where they fail to meet these standards, a disciplinary process applies. Furthermore, a WaterSafe approved plumbing business which fails to uphold the standards will be subject to a range of penalties; in serious cases, this would result in its membership of WaterSafe being revoked.

A WaterSafe approved business will be required to put their work right if it does not meet the requirements of the Water Fittings Regulations or Byelaws that are enforced by the water supply company.
