What to check before you book
This listing is compiled from public sources, so confirm these directly with the business before any work starts.
- For any gas or boiler work, confirm the engineer is on the Gas Safe Register (this is a legal requirement) and check their Gas Safe ID card. For plumbing and water work, look for WaterSafe, CIPHE or APHC membership.
- Get the quote in writing, and ask whether it includes parts, certification and VAT.
- Ask for proof of public liability insurance before work begins.
- For gas work, ask for the relevant certificate, such as a Gas Safety Record, once the job is done. Unvented hot water cylinders should be fitted by someone holding a G3 qualification.
