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.
Water-based underfloor heating, what's involved
Unlike electric underfloor heating, a water-based system runs off your boiler via a manifold and needs the floor buildup to accommodate the pipework — usually easier to fit during a renovation than retrofit into a finished floor. It's often paired with a lower-temperature heating setup than radiators use.
First fix and second fix plumbing
On a new build or extension, "first fix" is running pipework through walls and floors before they're closed up; "second fix" is fitting the visible taps, radiators and appliances once decorating is done. Timing this with other trades on site matters — pipework needs to be pressure-tested before it's covered over, not after.
Hard water and your plumbing
In hard water areas, limescale builds up inside pipes, taps, showerheads and boiler heat exchangers over time, gradually reducing efficiency and flow. A plumber working in a hard water area may recommend a water softener or scale inhibitor as part of a boiler installation, particularly for a system that's expected to last 10+ years.
How long does plumbing work take?
A tap or valve replacement is usually under an hour. A full bathroom refit commonly takes 5 to 10 working days depending on scope, plus time for tiling and decorating that isn't part of the plumbing work itself. A boiler swap is typically a one-day job if it's a straightforward like-for-like replacement.
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.
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.
Connecting new kitchen appliances
A new dishwasher or washing machine needs its own isolation valve and a suitable waste connection — if you're changing from an old appliance in a different position, this sometimes means new pipework rather than just reconnecting to the old point.
