Finding a Plumber in Eastleigh: What to Check Before You Book

Finding a decent plumber in Eastleigh is not hard, but finding one quickly and at a fair price requires a little preparation. Here is what to look for.

Gas Safe Register is non-negotiable

If any work involves gas — a boiler, gas hob, or a gas fire — the engineer must be on the Gas Safe Register. This is a legal requirement, not a nice-to-have. You can verify any engineer's registration at gassaferegister.co.uk using their registration number.

Never let an unregistered person work on gas appliances. The risk is carbon monoxide poisoning, explosion, or fire — and your home insurance will be void.

For general plumbing (not gas)

General plumbing work — fixing leaks, replacing taps, fitting bathrooms — does not require Gas Safe registration. For this type of work, look for:

- Checkatrade or TrustATrader listing with verified reviews
- Public liability insurance — ask for the certificate number and check it is current
- Local trading history — a business with a Hampshire base that has been operating for several years is lower risk than a sole trader using a mobile number
