APLUS approved plumbers

APLUS is an Anglian Water accredited scheme.

Members include plumbers/contractors who have shown they work to the legal, mandatory standards.


What are the benefits of using approved plumbers?


  • Approved plumbers are fully qualified to carry out plumbing work in homes and business premises. 
  • They have specific training in Water Fittings Regulations and Byelaws to ensure there should be no risk of poor installation or sub-standard materials that could cause contamination to your drinking water supply.
  • They will issue a compliance certificate for their work, which provides a defence for property owners who are challenged by a water supplier enforcing the Water Fittings Regulations and Byelaws.
  • Approved plumbers will be required to put their work right if it does not meet the requirements of the Water Fittings Regulations or Byelaws, enforced by the water supplier.
  • Should a concern arise, there is an independent complaints procedure in place to resolve any technical disputes about how the work has been carried out.
  • For most types of plumbing work, plumbers have a legal duty to notify the water supplier before they start work and this can lead to delays.
  • Approved plumbers are audited to check they are complying with the rules of their Approved Plumber scheme. 
  • Approved plumbers hold public and employee liability insurance.
