Reviewed, sourced guidance
Match plumbing work to the relevant check
Direct answer
Gas work has specific registration requirements. Water fittings work can involve Water Fittings Regulations and approved-plumber schemes. Other plumbing work may require different qualifications or notification checks. Ask the business what rule applies and verify that exact scope with the relevant authority.
There is no single lookup that proves every plumbing task is covered. Identify the work first, then check the relevant register, scheme or building-control route.
Key takeaways
- Do not treat one membership as a universal plumbing licence.
- Check gas registration for gas work.
- Check water-work scheme scope where water fittings are involved.
For domestic gas appliance work
Ask who will perform the gas work and how you can verify the relevant registration before it starts. Registration and competence relate to the work being performed.
HSE says anyone employed to work on domestic gas appliances must be Gas Safe registered and competent in that area of work.

For water fittings and supply work
Water Regs UK says approved-contractor schemes are voluntary; some operate in defined areas or certify only a limited work scope. WaterSafe lists members of those schemes but is not itself an approved-contractor scheme.
Ask whether the quoted task falls within the business or individual approval scope. Do not assume every membership covers every specialist service.
