Plumbing and selling your home
Buyers' solicitors sometimes ask about the age and condition of the boiler and any recent plumbing work, particularly if there's visible evidence of a past leak or repair. Keeping paperwork for any significant plumbing work — a new boiler, a bathroom refit, a burst pipe repair — makes this a much smoother conversation.
Finding a hidden leak
A leak inside a wall or under a floor isn't always obvious until it shows as a damp patch or a high water bill. Plumbers use damp meters, thermal imaging or (for harder cases) tracer gas to locate a hidden leak without having to open up an entire wall speculatively — worth asking about before agreeing to exploratory work.
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.
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.
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.
Workmanship guarantees on plumbing work
Most registered plumbers offer a workmanship guarantee separate from any manufacturer's warranty on parts like a boiler or a shower unit — commonly 12 months upwards. Ask what's specifically covered: a guarantee on a bathroom refit should cover the plumbing work itself, not just the visible fittings.
Blocked drains — causes and what a plumber checks
Slow-draining sinks are usually a local blockage (grease, hair, food waste) that a plumber can often clear with rodding or a drain snake. A blockage affecting multiple fixtures at once, or gurgling sounds from other drains, points to something further down the system — sometimes needing a drain camera survey rather than guesswork.
