- About Us
WIAPS is the largest of the six UK Approved Contractors’ Schemes. WIAPS is administered by Water Regs UK on behalf of 15 UK water companies.
It provides water industry backed accreditation to qualified plumbers and other sector workers, including groundworkers.
The new approved RPZ Valve Tester sector is now live and accepting applications. Please click here for more information.
Membership of WIAPS is currently free for Plumbers, Groundworkers and RPZ Valve Testers, but fees apply for other sector schemes.
Some organisations will only use businesses that employ Approved Contractors.
Every installation you undertake must comply with the Water Fittings Regulations. In addition, as an approved contractor, you issue a certificate stating your work complies with the Regulations. You must also make yourself available to be periodically audited by the local water company. This helps ensure high standards are maintained.
Joining is easy. Select the sector you wish to join here.
As part of your WIAPS membership, you’ll be signed up to WaterSafe at no extra cost. WaterSafe is a national register of approved contractors from all six Approved Contractors’ Schemes.*
*Membership of the WaterSafe Installers’ Scheme is currently only open to Approved Plumbers, External Services Contractors and RPZ Valve Testers.
