Background checks and identity verification
Before booking, it's worth checking a plumber's trading history and identity, not just their registration — a landline or verifiable business address and reviews referencing specific jobs are stronger signals than a mobile number and a van sign alone.
Three steps to hiring the right plumber
First, check they're registered with a WaterSafe scheme (or Gas Safe too, if the job needs it) and ask for the registration number. Second, get a written quote that separates labour from parts. Third, ask what happens if the job uncovers a bigger problem — a good plumber will tell you before continuing, not after.
Common plumbing jobs
Plumbers handle everything from a dripping tap to a full bathroom re-pipe: fixing leaks, clearing blocked drains, replacing taps and valves, fitting new bathroom suites, repairing or replacing radiators, and connecting appliances like washing machines and dishwashers. Emergency work (burst pipes, no hot water) is usually handled separately from planned jobs like a bathroom refit.
How many quotes should you get?
Three is a reasonable number for most plumbing jobs — enough to spot an outlier without asking too many people to visit for a straightforward repair. For a planned job like a bathroom refit, make sure each quote covers the same scope, since a lower price sometimes means less is included, not better value.
Aftercare after plumbing work
After a boiler installation or bathroom refit, you should receive a benchmark/commissioning checklist (for a boiler) or a written summary of the work done, which you'll want if you make an insurance claim or sell the property later. Keep it with your household paperwork alongside any appliance warranties.
Red flags in a cheap plumbing quote
A quote significantly below the others is worth questioning before accepting — check it specifies the same quality of parts (a boiler make/model, not just "a boiler"), includes making good after any pipework is exposed, and covers testing before the job is signed off as complete.
Protecting pipes in cold weather
Pipes in unheated spaces — lofts, garages, outbuildings — are the most common source of a winter burst pipe once temperatures drop below freezing for a sustained period. Lagging exposed pipework and keeping heating on a low constant setting during a cold snap, rather than off, are the two most effective preventive steps.
Understanding the labour vs materials split
Materials — pipework, fittings, a new boiler or bathroom suite — are often a smaller share of a plumbing quote than labour, particularly for jobs involving lifting floors or chasing walls. If a quote looks unusually cheap, check whether it specifies the same brand/quality of fittings as a competing quote, not just a lower labour rate.
