What this covers: the plumbing side of a kitchen — fitting or replacing a sink and taps, connecting and moving appliances (dishwasher, washing machine, fridge water line, waste disposal), sorting kitchen leaks, and the waste pipework that carries it all away. The sections below cover what a kitchen job actually involves, and the one Newham habit that causes the most blockages.
Routing: just plumbing in one appliance or a single tap has its own page; an already-blocked sink is drainage, and a hidden leak with no source is leak detection.
Costs: from a tap swap to a full kitchen’s supply and waste. See What it costs below.

What a kitchen job involves
Most of a kitchen’s plumbing is out of sight — the supply pipes and waste runs behind the units — which is why a kitchen refit is more plumbing than it looks.
A kitchen plumber handles the sink and taps, the hot and cold supply to them, the waste trap and pipework, and the supply and waste connections for appliances. In a new or moved kitchen, that often means re-routing supply and waste to a new sink or island position, adding isolation valves so a tap or appliance can be turned off without draining the house, and making sure the waste has the right falls so it drains properly. A kitchen mixer tap, a filtered or boiling-water tap, and a waste disposal unit are all common additions.
Newham is a hard-water area — Thames Water classes all its supplies as hard — so limescale furs up kitchen taps, aerators and the elements in boiling-water taps and dishwashers over time.1 It doesn’t change how a kitchen is plumbed, but it’s worth choosing tap aerators you can unscrew and descale.
Appliances and the waste
The appliance connections are where a lot of kitchen plumbing problems start, and where a flat adds a wrinkle.
A dishwasher and a washing machine each need a supply connection and a waste connection, usually teed into the sink waste or a dedicated standpipe, with the appliance’s drain hose looped correctly so waste water can’t siphon back. A fridge with an ice maker or water dispenser needs a cold supply teed in. Done properly these are reliable; done badly they’re a common source of slow leaks under the units and into the cupboard below.
In a flat, the waste from a kitchen sink and appliances usually runs into a communal soil or waste stack shared with other homes — and where a problem sits decides who fixes it. Your own branch waste, up to where it joins the shared stack, is yours; the building’s communal stack and internal shared pipework are usually the freeholder’s or managing agent’s under the lease; and the public sewer beyond the building is the water authority’s, since Newham Council notes that a pipe serving more than one property is a sewer and the water authority’s responsibility rather than the council’s.2 So in a managed block, a kitchen blockage means first working out whether it’s in your own waste, the shared stack, or the sewer. With flats now 54.6% of Newham’s dwellings — the largest local-authority rise in England, the ONS records — that shared-stack situation is common here.3
If you only need one appliance plumbed in rather than a kitchen’s worth, that’s covered on the washing machine & dishwasher installation page.
Fat, oil and grease — the Newham problem
One of the most common kitchen-drain problems isn’t the install — it’s what goes down the sink afterwards.
Thames Water says over 80% of sewer blockages are caused by fat, oil and grease, or by paper and rag including wipes.4 Fat poured down the sink as a hot liquid cools and sets solid in the pipe, narrowing it until it blocks — and the kitchen sink is a main route by which it enters the system. That matters more in Newham than in many boroughs: the council’s surface-water management plan identifies thirteen Critical Drainage Areas and estimates around 17,500 homes could be at risk of surface-water flooding in an extreme rainfall event, on a low-lying drainage network that includes combined foul-and-surface-water sewers and copes badly with anything narrowing the pipes.5
The fix is a habit, not a part: let fat cool and bin it rather than pouring it away, scrape plates before washing, and use a sink strainer. A well-installed waste with the right trap and falls helps, but nothing protects a kitchen drain like keeping grease out of it. An already-blocked kitchen waste is covered on the blocked drains page; a food business’s grease management is commercial work.

Newham’s kitchen plumbing runs from terraced-house refits to flats sharing a waste stack.
East Ham, Forest Gate, Manor Park and Plaistow (E6 / E7 / E12 / E13). The terraced and converted-house belt, where full kitchen refits, re-routed sinks and appliance connections are the common work, and older waste runs sometimes need updating as part of the job.
Stratford, Stratford City, East Village and the Royal Docks (E15 / E16 / E20). Modern managed flats, where kitchen waste usually feeds a communal stack, so an appliance connection or a waste problem can involve the building — worth confirming whether the issue is your pipework or the shared stack.
Green Street and Upton Park (E7 / E13). The market-and-high-street belt around Queen’s Market — which Newham Council describes as sitting among small shops, cafés and restaurants and selling fresh fish, seafood, meat, fruit and vegetables — where grease and food waste from the food premises are part of daily trade. A food premises’ kitchen drainage is commercial work rather than a domestic kitchen job.
Canning Town and Custom House (E16). Part of Newham’s £3.7 billion regeneration programme — 10,000 new homes, 3,500 already completed or on site, the council says — so much of the stock is newer flats with modern kitchens on communal waste systems, where the work is more often an upgrade or appliance connection than a first fit.6
What it costs
Kitchen plumbing ranges from a quick tap swap to a full kitchen’s supply and waste. The figures below are a general guide for London, not a quote.
| Job type | Indicative range (London) |
|---|---|
| Replace a kitchen tap or mixer | £80–£200 |
| Plumb in a dishwasher or washing machine | £80–£180 |
| Fit a waste disposal unit | £150–£350 |
| Re-route sink supply and waste (new layout) | £250–£600 |
| Full kitchen plumbing (refit, excl. units) | £600–£1,800+ |
Editorial estimate only. These figures are an indicative guide to help you plan — they are not regulated rates, not market data, and not a published cost survey. A kitchen refit usually combines plumbing with units, electrics and worktops, so confirm exactly what a quote covers. For reading a quote, see how to read a plumbing quote and the London plumbing costs guide.
Newham is within the London-wide Ultra Low Emission Zone, which Transport for London operates 24 hours a day across every London borough, with a daily charge for vehicles that don’t meet its emissions standards.7 A plumber using a non-compliant vehicle may factor that into their pricing, so it’s reasonable to ask.
Frequently asked questions
A straightforward swap onto existing connections is doable, but getting the supply, the waste connection and the drain-hose loop right matters.
A badly connected appliance is a common cause of slow leaks under the units.
If you only need the one appliance done, see the appliance installation page.
Usually fat, oil and grease setting in the pipe.
Thames Water says those, with wipes, cause over 80% of sewer blockages.
Bin fat rather than pouring it away, scrape plates, and use a strainer.
If it’s already blocked, that’s blocked drains.
No — even with hot water it cools and sets further down the pipe.
In Newham’s low-lying drainage it builds into blockages quickly.
Let it cool and bin it.
Often, yes.
Kitchen waste in a flat usually runs into a communal stack shared with other homes, so a blockage or a poorly connected waste can affect them.
Where the fault sits decides who’s responsible: your own branch waste is yours, the shared building stack is usually the freeholder’s or managing agent’s, and the public sewer beyond the building is the water authority’s.
Many kitchen plumbers do.
In hard-water Newham, bear in mind the heating element and filter will scale up over time.
Factor in descaling or filter changes.
That’s usually a kitchen fitter’s job.
The plumber does the sink, taps, appliance connections and waste.
Many work alongside a fitter — confirm who’s doing what before the job starts.

Connect it properly, and keep fat out of the sink. A kitchen in Newham is mostly hidden plumbing — supply and waste behind the units, appliance connections that leak if they’re done badly — and in a flat that waste often feeds a stack shared with neighbours, where the line between your pipe and a shared sewer decides who fixes a problem. But the thing that blocks a kitchen drain most is fat poured down it, which on Newham’s low-lying drainage is worth taking seriously. Get the connections right and bin the grease — and a verified Newham plumber from the list above can fit, move or repair it.
