PLUMBING ESSENTIALS
A quick guide to planning your project, understanding costs and choosing a good Plumber.
WORTH KNOWING
A full bathroom refit usually means removing the old suite, checking and often replacing the pipework behind it (since it's rarely accessible again once tiled over), first-fix plumbing before tiling, then second-fix (taps, shower, toilet cistern) once the room is finished. Waterproofing (tanking) around a shower area is a step worth confirming is included, not assumed.
WORTH KNOWING
A toilet that runs constantly is usually a worn flush valve or float mechanism inside the cistern — a relatively cheap fix compared to replacing the whole toilet. A slow-filling cistern often points to a partially closed isolation valve or low mains pressure rather than a fault with the toilet itself.
THE PROCESS EXPLAINED
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.
UNDERSTANDING THE JOB
Modern combi boilers display a fault code when something's wrong rather than just stopping — the exact meaning varies by manufacturer, but common causes behind a "no heat" code include low pressure, a faulty sensor, or an ignition fault. Note the code before calling a plumber; it speeds up diagnosis considerably.
SAFETY & COMPLIANCE
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.
SAFETY & COMPLIANCE
Do I need a certificate for a new bathroom? There's no single certificate like Part P for electrics, but any work must comply with Water Fittings Regulations, and gas-connected work needs a Gas Safe engineer. Can I do my own plumbing? Straightforward repairs, yes; anything affecting the public water supply (like a new connection) should go through a WaterSafe-approved plumber.
THE PROCESS EXPLAINED
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.
RULES & STANDARDS
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.
AREA GUIDE
New Malden is a large town in Greater London, inside the London region and served by the KT3 postcode district. No population figure is supplied, but its large‑town tier indicates a significant residential and commercial area rather than a small settlement. As part of Greater London, local authority services and planning fall under the relevant London borough and are influenced by London planning and transport frameworks. Using KT3 in a trades search helps locate contractors who work across south-west London and the Surrey border suburbs. In a town of this scale expect a range of housing types — from suburban semi‑detached homes to terraces and smaller apartment blocks — so common trade jobs include loft insulation, boiler servicing and kitchen or bathroom modernisation. Suburban parking is usually easier than central London, but street permits and driveway availability remain important considerations when arranging work.
In New Malden’s varied housing stock, plumbing work ranges from repairing ageing pipework in older semis and terraces to first‑fix plumbing for loft conversions or kitchen extensions in newer properties. Older homes in the area commonly present copper pipes showing wear or historic installations that benefit from pipework replacement and bathroom modernisation, while the many smaller apartment blocks often need targeted drainage, tap and toilet servicing rather than whole‑house replumbs. Being inside Greater London with KT3 postcode links means plumbers who serve New Malden are used to working where driveway access and street permit issues can influence where they park vans and how they route materials.
For unvented cylinder work a G3 qualification is required; this matters because incorrect installation of pressurised systems creates a safety risk and may invalidate insurance. Water supply fittings must be WRAS‑approved to ensure materials won’t contaminate the mains, so insist on compliant parts for any replacement. When hiring, ask plumbers for proof of G3 or relevant qualifications, request confirmation that they use WRAS‑approved fittings, and get a clear plan for how they’ll manage access and waste removal given suburban parking and possible permit restrictions. Also obtain a written quote showing whether pipe replacement, tanking or drainage work is included.
