The plumbing side of a kitchen

Like a bathroom, a kitchen refit is several trades — this is the plumbing part. It runs as a first-fix (hot, cold and waste pipework to the sink and appliance positions, before units go in) and a second-fix (connecting the sink, tap, waste and appliances once the kitchen is fitted).

The sink and its waste are the heart of it. A kitchen waste needs the correct fall, the right trap and a connection that won’t let the seal siphon out, and a kitchen trap takes a fair amount of grease and food residue over its life — so accessible, serviceable pipework pays off. Under the sink, a good plumber checks the trap layout, the appliance spigots, caps any unused outlets, routes and secures the hoses, and leak-tests everything before the cupboard is loaded. A sink that blocks repeatedly often points to fats and food, a poor fall, a long flat or sagging waste run, or a shared-stack restriction rather than just the trap — which is covered on Blocked Drains.

Moving a sink or appliances more than a short distance, or running new drainage, may need Building Regulations advice or approval, especially where new drainage is created or re-routed.⁵ In a flat, a sink move also turns on the stack position, the fall available, the joist direction, whether pipe boxing or access panels are needed, and any lease or freeholder restriction on altering shared services — all worth checking before the units are ordered.

New fittings and pipework should be of an appropriate quality and standard and installed in a workmanlike manner under Regulation 4 of the Water Supply (Water Fittings) Regulations 1999.¹ In practice, plumbers evidence this with fittings carrying WRAS, NSF REG4, Kiwa or equivalent approval.² Plumbing in the washing machine or dishwasher itself — fill, waste and backflow — has its own installation page.

Water softeners and your drinking tap

Hard water makes softeners popular in H&F — but there’s one rule that matters for health, and it’s worth stating plainly. The Drinking Water Inspectorate advises that if you install a water softener, you should not soften the kitchen tap used for drinking and cooking, because most softeners work by replacing the hardness with sodium — which can be a problem for premature babies and for anyone on a low-sodium diet — so an unsoftened outlet should be provided for drinking water.³

In practice that means keeping the kitchen cold tap (or a separate drinking tap) on the unsoftened mains, while the softened supply serves the hot water and the rest of the house. The DWI also notes that a softener should be correctly installed by a qualified plumber and kept maintained so it doesn’t become a hygiene problem.³ A good softener installation includes a bypass valve, accessible salt loading, a safe drain and overflow route, and a clearly unsoftened drinking-water tap — so a plumber plans the softener and the drinking tap together, and you get the benefit on the hot side without softening what you drink.

Hard water in the kitchen

Even without a softener, hard water shapes kitchen plumbing here. H&F sits in Thames Water’s region, where the water is hard because it passes through chalk and limestone.⁴ In the kitchen, scale shortens the life of mixer cartridges, furs up the aerator on the spout, and builds up in anything that heats water — kettles, of course, but also the inlet sides of dishwashers. Choosing a quality mixer with matchable parts, and descaling the aerator periodically, keeps a kitchen tap working far longer. Our London hard water guide covers the wider effects across the home.

Find a verified plumber by district

Kitchen plumbing follows the building — its waste runs, its access and its system.

Hammersmith, Ravenscourt Park & Fulham Reach (W6) — Victorian conversions and flats where the kitchen waste runs to a shared stack, and flats above shops on King Street where a kitchen leak or appliance flood can reach the home or business below.

Shepherd’s Bush, White City, Wood Lane & Wormholt (W12) — period terraces, mansion blocks and estate flats including the White City Estate, where shared stacks and communal drainage shape kitchen waste runs and, in council flats, the repair route.

Fulham, Fulham Broadway, Parsons Green, Walham Green & Munster (SW6) — mansion blocks and converted Victorian houses, often with original kitchen waste runs of marginal fall and the long under-sink hose arrangements that come with retrofitted appliances.

Sands End, Imperial Wharf & the riverside (SW6) — newer riverside apartments with mains-pressure systems and concealed pipework, where isolation and waste may run through a riser and access goes via building management.

West Kensington, Barons Court, Avonmore & North End (W14) — older flats and conversions plus the West Kensington and Gibbs Green estates; W14 is shared with Kensington & Chelsea, so check your plumber covers your side.

Brook Green & Addison — period flats and mansion blocks where older kitchen layouts and awkward waste routes are the usual considerations.

What kitchen plumbing costs

The plumbing is one element of a kitchen’s cost, alongside units, worktops, building and electrics. For the plumbing, as a rough orientation only:

Kitchen plumbing job	Editorial estimate (guide only)
Supply & fit a kitchen sink & mixer	£150–£350 plus the units
Replace a kitchen waste / trap	£90–£180
Plumb in appliance feed & waste	£90–£200 per appliance
Supply & fit a water softener	£400–£900 plus the unit
Kitchen refit plumbing (first + second fix)	£600–£1,800+

Editorial estimate only — these are general guide figures, NOT regulated rates, NOT market data and NOT a published cost survey. They cover the plumbing only, not units, worktops, building or electrical work. Always get a written quote. Hammersmith & Fulham is inside London’s Ultra Low Emission Zone, so a non-compliant van may carry the £12.50 daily ULEZ charge.⁶ The borough is outside the central London Congestion Charge zone, so that charge doesn’t normally apply to local callouts.⁷ Our how to read a plumbing quote guide helps you compare refit quotes fairly.

Frequently asked questions

The Drinking Water Inspectorate advises keeping the kitchen drinking and cooking tap on the unsoftened mains, because softeners add sodium that isn’t suitable for premature babies or people on a low-sodium diet.

The usual setup softens the hot water and the rest of the house but leaves a drinking tap unsoftened.

Drinking Water Inspectorate — water softeners

Usually just the plumbing — first-fix pipework and second-fix sink, tap, waste and appliance connections.

Units, worktops, tiling and electrics are separate trades, though some plumbers project-manage the lot.

Sometimes, but a sink that blocks repeatedly often points to fats and food, a poor waste fall, a long flat or sagging waste run, or a shared-stack restriction rather than just the trap.

A plumber can tell which.

Moving a sink or appliances more than a short distance, changing connections or running new drainage may need Building Regulations advice or approval.

A like-for-like replacement in the same spot generally doesn’t.

Only if they’re Gas Safe registered — a gas hob connection is gas work.

Many kitchen plumbers aren’t gas engineers, so check, or use a Gas Safe engineer for that part.

Why verified plumbers — not a general directory

A kitchen packs a lot of concealed plumbing behind units and under the sink, where a weak joint or a poor waste run doesn’t show until it leaks — often into a cupboard of food or, in a flat, the ceiling below. That’s where verifying the plumber first earns its keep.

Every listing is checked before it goes live and re-verified annually. We confirm the business is legitimately trading and verify the named contact, we check for evidence of public liability insurance, and we confirm the plumber covers H&F’s W6, W12, SW6 and W14 postcodes before a profile is approved. For water-supply and fittings work, you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register. Where any gas appliance is involved, we confirm Gas Safe registration directly with the Gas Safe Register.

Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. No customer middleman fee: enquiries go directly to the plumber.
