Sink-side repairs: what goes wrong under there
Leaks under the sink. The under-sink cupboard is a junction box: supplies, isolation valves, flexible tails, trap, waste, appliance tees. Most leaks are a connection loosened by time, vibration or stored saucepans — find which joint is wet when water runs, because a trap leaks when draining, a supply leaks always, and an appliance tee leaks on its cycle. The cupboard hides damage well: swollen chipboard is usually the first honest witness — and in converted houses around Richmond or Twickenham town centre, the leak can show in the flat below before the cupboard looks badly wet, which adds a block-manager or freeholder conversation to the plumbing one.
The trap and waste. Slow draining is fat and food debris until proven otherwise; smells with good drainage are usually a trap or seal issue. Clearing the trap is legitimate DIY (bowl underneath, unscrew, empty, refit); recurring or multi-fixture problems escalate to the Blocked Drains page.
Taps. The kitchen tap is the most-used valve in the home and this borough’s water is hard on it — drips, stiff handles and scaled aerators live on the Tap Repair page, including the cartridge and pressure-matching detail.
Isolation that works. Every kitchen supply — sink, appliances, any softener — should isolate locally. In the borough’s older kitchens and converted flats it often doesn’t, and in a Richmond or Twickenham flat above a shop, an under-sink leak is the business below’s ceiling: working isolation valves and sound flexible tails are the cheap insurance. Where kitchen pipework is boxed behind units in a leasehold flat, expect the sensible sequence — isolate locally and make safe first, then agree access with the owner, landlord or managing agent before panels get cut. The General Plumbing page covers the valve-fitting visit.
The fat rule: the cheapest plumbing advice in this borough
Fat, oil and grease leave the pan as liquid and set in the pipe as something close to concrete — first in your trap and waste run, then in the shared drain where the bill stops being yours alone. The discipline is simple and absolute: cooled fat goes in a container and then the bin; greasy pans get wiped before washing; the sink is for water. Hot water can help rinse a recently used trap, but it isn’t a disposal method for fat and won’t clear set grease downstream — and in the older terraces of Mortlake, Barnes or Teddington, where several homes can share an ageing downstream run, repeated slow draining may be more than your trap: it’s where everyone’s shortcuts accumulate until the drain page’s diagnosis-and-responsibility question arrives. Food businesses run the industrial version of this rule — grease management as compliance — on the Commercial Plumbing page.
Refits and layouts: first-fix decides everything
A kitchen refit moves the sink across the room on a drawing in seconds; the plumbing has opinions about it.
- Waste fall is the hard constraint. The sink waste needs continuous fall to the stack or gully, and islands need real engineering — a long under-floor run with proper fall, or an air-admittance arrangement designed rather than improvised. “The island sink gurgles” is a design failure tiled into the floor.
- Supplies sized and routed for the new layout, with isolation at every take-off, and appliance positions tee’d properly rather than daisy-chained from whatever was nearest.
- The dishwasher and washing machine positions want their supply, waste and backflow protection planned now — the appliance installation page covers the standard that work should meet.
- The softener question gets decided here. If a softener is in the plan, Thames Water’s advice is that softened water isn’t recommended for drinking or cooking — installations should keep a separate unsoftened drinking supply1 — which means a dedicated drinking tap or a triple-flow mixer, planned into the worktop before it’s cut.
- The paperwork. Fittings work must meet the Water Supply (Water Fittings) Regulations 1999, Regulation 4 — appropriate quality and standard, installed in a workmanlike manner.2 Separately, Regulation 5 requires advance notice to the water undertaker — here, Thames Water — before certain listed installations begin, with consent obtained first; some notifiable work is exempt when carried out by an approved contractor.3 Ask your installer what applies to your job and who handles any notice.
Like every refit, it’s the cheap moment for the boring upgrades: isolation everywhere, a stop tap that turns, flexible tails that aren’t ten years old. The units go in once.
Hard water in the Richmond kitchen
Thames Water confirms all the water in its region is hard — over 300 mg/l of calcium carbonate counts as very hard1 — and the kitchen is where the household meets that fact daily: the kettle’s crust, the scaled aerator, the white film on the draining board, the dishwasher asking for salt. The plumbing consequences are steady rather than dramatic — tap cartridges and washers as service items, appliances worth protecting (the dishwasher’s own salt system, inline protection where appropriate), and the softener decision above with its separate-drinking-tap rule. Hardness varies by postcode, so check yours with Thames Water rather than assuming one figure borough-wide. The full picture — what scale actually does and what’s worth spending on — is in the London Hard Water guide.
Renting? With nearly a quarter of the borough’s households renting privately per the Office for National Statistics,4 the usual split applies in the kitchen too: worn fixtures and failing pipework are generally the landlord’s repair; blockages from what went down the sink tend to sit with the tenant — the fat rule is also a deposit-protection rule. RHP tenants: kitchen repairs route through RHP on 0800 032 24335 — report before paying privately.
What kitchen plumbing costs in Richmond upon Thames
Each listed plumber sets their own prices and quotes directly — these figures are an editorial guide to the local range, nothing more.

Editorial estimates only — not regulated rates, not market data. On refits, the questions that matter: is the waste fall achievable for the layout, where does isolation live, and is the softener/drinking-tap decision in the drawing? Our How to Read a Plumbing Quote guide covers the rest; the London Plumbing Costs & Compliance Guide has the wider picture.
Frequently asked questions
Match the leak to the moment: wet only when draining points to the trap or waste; wet all the time points to a supply joint or flexible tail; wet after the dishwasher runs points to its tee or hose.
Dry everything, run each in turn, and watch.
Swollen chipboard means it’s been going on longer than today — fix the joint and check what the water reached.
Trap first: a bowl underneath, unscrew it, empty it, refit — that’s most slow kitchen sinks fixed, because fat and food collect exactly there.
If the trap is clear and the sink still struggles, if it keeps coming back, or if other fixtures gurgle too, the blockage is further down the run.
That’s when it moves from trap-cleaning to the Blocked Drains page: CCTV on anything recurring, and the shared-drain check that can make it Thames Water’s problem rather than yours.
Yes — if the waste is engineered, not improvised.
An island sink needs a long under-floor waste run with continuous fall to the stack or gully, or a properly designed venting arrangement.
Get it wrong and the island gurgles, smells and drains badly forever, because the fix is under the floor.
It’s the first question to settle in any island layout, before electrics and before stone.
The water makes the case: Thames Water classifies its whole region as hard.1
Whether a softener repays its cost depends on your scale problems and appetite for salt refills — but if you fit one, Thames Water’s advice is clear: keep a separate unsoftened drinking supply, since softened water isn’t recommended for drinking or cooking.1
That’s a worktop and tap decision, so make it during the design, not after.
Fat, oil and grease above all — liquid in the pan, concrete in the pipe.
Cooled fat goes in a container and the bin; greasy pans get wiped first.
Coffee grounds, rice and starchy debris are the supporting cast.
The trap catches some of it; the cold shared drain downstream catches the rest, and that’s where one household’s habit becomes the terrace’s blockage — see the fat rule .
At the drawing stage, before anything is ordered.
The waste fall decides whether the sink can move; supplies, isolation and appliance positions get planned once; the softener/drinking-tap question shapes the worktop.
A plumber who sees the layout early prevents the expensive version of every one of those conversations — and the first-fix happens while the room is open.
Worn fixtures, failing joints and tired pipework are generally the landlord’s repair; blockages caused by what went down the sink tend to sit with the tenant — which makes the fat rule a deposit-protection rule too.
Nearly a quarter of the borough rents privately,4 so it’s a routine conversation.
RHP tenants report on 0800 032 24335 before paying privately.
