Water safety courses explained.
Fitting cylinders or working to the regulations? These answers explain which qualification your work needs.
Yes. Under G3 of the Building Regulations, only competent persons may install, commission or service unvented hot water systems over 15 litres.
The recognised proof of competence is the Hot Water Systems and Safety (HWSS) certificate, which covers safe installation, the three-tier safety strategy, discharge pipework and servicing. It is also what Competent Person Schemes require before you can self-certify this work.
Without it, installations must be notified to Local Authority Building Control instead.

Yes. HWSS replaced the standalone Unvented Hot Water course and covers both vented and unvented systems in one qualification, in line with G3.
If your existing certificate is titled "G3 Unvented" or "Unvented Hot Water", the HWSS re-assessment is now your renewal route. The content includes everything from the old course plus the wider G3 requirements for vented systems.
See the HWSS course page for both initial and re-assessment routes.

See the HWSS course page for both initial and re-assessment routes.
Yes. The HWSS certificate is valid for five years from the date of issue and must be re-assessed to stay valid.
If your certificate has expired within the last 12 months you can take the shorter re-assessment route. If it expired more than 12 months ago, you must complete the full initial assessment again. Water Regulations certificates are also commonly refreshed on a five-year cycle by approved plumber schemes and contractors, so most engineers renew both together.
Keeping HWSS in date is also what maintains your ability to self-certify through a Competent Person Scheme.

The Water Regulations course covers the Water Supply (Water Fittings) Regulations 1999, including backflow prevention, the five fluid risk categories, fittings compliance and notification requirements.
The Regulations are the law governing how water fittings must be installed to prevent waste, misuse and contamination of the public supply. WRAS approves compliant fittings and publishes the Water Regulations Guide that the industry works to.

Both are experienced-level qualifications, so they assume you are already working in plumbing or heating rather than starting out.
For HWSS you need experience installing domestic hot and cold water systems, both vented and unvented, plus a recognised competency in a conventional fuel such as gas or oil, or an NVQ Level 2 or equivalent if you work in the plumbing sector.
If you are new to the trade, start with the Level 2 Plumbing Diploma and add these afterwards.

Yes. The WIAPS Water Industry Approved Plumber Scheme expects the Water Regulations qualification alongside an NVQ Level 2.
Approved plumber status lets you self-certify water fittings work, which speeds up jobs and is recognised by water suppliers nationwide. Many plumbers take Water Regulations and HWSS together to cover the full range of domestic work.
