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.
What affects the cost
Cost depends on the scope of the job, how accessible the pipework is (under a floor vs behind a wall), whether parts need to be sourced specially, and whether the job is planned or an emergency call-out. A simple tap or valve replacement is usually quick and low-cost; anything requiring pipework to be rerouted, or walls/floors to be opened up, costs more partly because of the making-good work afterwards.
Plumbing responsibilities for landlords
Landlords are responsible for keeping water and heating systems in safe working order, and if there's a gas boiler, a valid annual Gas Safety Certificate is a legal requirement, not optional. A burst pipe or heating failure in a rented property is generally treated as an emergency repair the landlord must address promptly.
Do you know where your stopcock is?
Every property has a main stopcock (usually under the kitchen sink, though sometimes in a different location in older or converted properties) that shuts off the water supply. Knowing where it is and checking it turns freely, before you need it in an emergency, is one of the simplest things a homeowner can do.
Copper vs plastic pipework
Copper pipework is the traditional standard and suits exposed runs; plastic (PEX/push-fit) pipework is faster to install and commonly used for pipework buried in walls or floors where copper joints would be harder to check later. Most plumbers use a mix depending on the specific run, not one material throughout.
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.
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.
Plumbing in a washing machine or dishwasher
Both need a cold water supply, a drain connection, and in most cases their own isolation valves so they can be disconnected without turning off water to the whole property. Using a shared valve with another appliance is a common shortcut that makes future repairs more disruptive than it needs to be.
