Your enquiry goes straight to the plumbers you pick — no middleman fee
An appliance that fills and drains looks installed.

The verified plumbers below do appliance connections properly across the borough.

What a proper installation actually includes
A dedicated, isolatable supply. The appliance connects to a proper tee with its own quarter-turn valve — so it can be serviced, swapped or shut off without touching the rest of the kitchen. A valve buried behind the unit it serves is technically present and practically useless; placement matters.
Backflow protection that satisfies the Regulations. Appliance connections must prevent dirty water being drawn back into the drinking supply — modern machines carry protection in their design, and connections are made with compliant fittings rather than improvisation. The legal floor for all of it is the Water Supply (Water Fittings) Regulations 1999, Regulation 4: fittings of appropriate quality and standard, installed in a workmanlike manner.1 “It fills, doesn’t it?” is not the standard.
Cold-fill reality. Most modern machines are cold-fill only; capping the redundant hot supply properly — not leaving a weeping valve behind the unit — is part of the job when replacing an older machine.
A waste connection that’s designed, not poked. Next section — it’s where most bad installs live.
Levelling, testing, and the boring finish. The machine levelled (an off-level washer walks and hammers its own connections loose), transit bolts out, a full test cycle run with the plumber present, the floor checked dry afterwards, and the isolation valve’s location shown to you before they leave. Integrated appliances add carpentry tolerances; say “integrated” when you book, because the access and time are different.
The waste question
Appliance waste has three legitimate destinations: a dedicated standpipe with trap, a tee into the sink trap’s appliance spigot, or a purpose-made waste connection — each with the hose looped high so the machine can’t self-siphon, and each ending in a trap so the kitchen doesn’t smell of drain. The classic failures are all shortcuts: a hose shoved down a standpipe without an air gap (siphoning and smells), a pushed-on spigot connection with no clip (comes off on the first hot drain), a waste run uphill on hope (standing water, stink, blockage).
Two symptoms worth reading correctly. Water backing up into the sink when the machine drains usually means a partial blockage in the shared waste run — fat and lint meeting in the trap — which starts as a Kitchen Plumbing trap-clean and escalates, if it recurs, to the Blocked Drains page. The machine draining fine but the kitchen smelling after cycles points at the air gap, the trap or a dried seal — an installation detail, not a drainage emergency.
Hoses: the quiet risk in the house
A washing machine’s fill hoses hold mains pressure 24 hours a day and are the only mains-pressure component in most homes made of rubber. They age invisibly — and when one lets go, it delivers the full flow of an open pipe until someone isolates, which is precisely the Burst Pipes scenario with a kitchen floor as the catchment. The discipline costs almost nothing: inspect hoses when you clean behind the machine, replace anything showing rust at the connectors, bulging, kinks or perishing, treat roughly five years as a sensible service life rather than waiting for failure, and — the one that saves homes — turn the appliance valves off before holidays. If your valves are seized or buried, that’s exactly the small job the General Plumbing page exists for.
In a flat, multiply the stakes by the ceiling below: an unattended hose failure in a Richmond or Twickenham mansion flat or a flat above a shop is a neighbour’s ceiling, a managing agent and an insurance conversation before it’s a plumbing one. The evidence habits from the Leak Detection page — photographs, the cause noted in writing — apply in full.
Flats, rentals and this borough
Hard water sets the maintenance rhythm. Thames Water confirms all the water in its region is hard2 — which is why the dishwasher asks for salt, why inlet filters scale, and why appliance longevity here rewards using the machine’s own water-hardness settings and keeping filters clean. Set the dishwasher’s hardness to your postcode’s actual figure (check it with Thames Water) rather than the factory default. The wider picture is in the London Hard Water guide.
Renting: who installs, who repairs, who pays. With nearly a quarter of the borough’s households renting privately per the Office for National Statistics,3 the usual pattern: where the appliance belongs to the landlord, its connection and failures are generally theirs; where it’s your machine in their property, the installation is typically yours to arrange — done properly, with permission where the tenancy requires it, because a flood from your machine is a much harder conversation than a flood from theirs. Get the connection done to the standard above and keep the invoice. RHP tenants: check with RHP on 0800 032 24334 before commissioning work — plumbing fabric is normally their side, your own appliance is normally yours.
One practical borough note: delivery-and-install crews fit machines by the thousand and mostly fit them fine — but they connect to what’s there. If what’s there is a seized valve, a corroded tee or a waste with no trap, the proper fix is a plumber’s half-hour before delivery day, not a crew’s improvisation on it.
What appliance installation 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.
| Job | Typical editorial estimate |
|---|---|
| Washing machine or dishwasher connected (existing services) | £60–£120 |
| New supply tee + valve + waste connection created | £120–£250 |
| Appliance relocated (new position, new services) | £150–£300+ |
| Fill hoses / valves replaced | £60–£110 |
| Integrated appliance swap | £90–£180 |
Editorial estimates only — not regulated rates, not market data. The questions that sharpen a quote: is a new tee and valve needed or just a connection, is the waste route compliant or improvised, and will a full test cycle be run before sign-off? Our How to Read a Plumbing Quote guide covers the rest; the London Plumbing Costs & Compliance Guide has the wider picture.
Frequently asked questions
Often not — delivery crews connect machines to sound existing services perfectly well.
You need a plumber when the services themselves are the problem: a seized or missing isolation valve, a corroded tee, a waste with no trap or air gap, or a new position needing supply and waste created.
The honest test: if the crew would be connecting to something you wouldn’t trust, fix that first.
It’s a half-hour job before delivery day, not a doorstep improvisation.
Almost always the waste detail.
It may be a hose pushed too far down a standpipe with no air gap, a missing or dried-out trap, or a self-siphoning loop.
The machine is fine; the installation is talking.
It’s a quick correction — and a good example of the difference between “it drains” and “it’s plumbed.”
See the waste question.
The dishwasher and sink share a waste run, and something downstream of the junction is partly blocked.
Typically, that’s fat and food debris at the trap or just beyond.
Start with the trap clean on the Kitchen Plumbing page.
If it recurs, the run itself needs attention — that’s the Blocked Drains page, including when a shared drain makes it Thames Water’s job.
Inspect them whenever you clean behind the machine.
Replace them at any sign of rust at the connectors, bulging, kinks or perishing.
Treat roughly five years as a sensible service life rather than a guarantee.
They hold mains pressure around the clock, and failure is a flood, not a drip.
Turning the appliance valves off before holidays is the cheapest insurance going.
See hoses: the quiet risk.
Sometimes.
The plumbing wants a supply, a compliant trapped waste with enough fall, and isolation.
Bathrooms add electrical-safety zoning rules that are an electrician’s call, and unusual positions add waste-route engineering.
It’s exactly the kind of relocation to price as a small project rather than assume: supply, waste, electrics, ventilation, then the machine.
Two things: consequence and access.
A hose failure or waste leak is the ceiling below — so working isolation valves, sound hoses and valves-off-before-holidays matter more.
The evidence habits — photos and written cause — from the Leak Detection page apply if anything does go through.
In mansion blocks and flats above shops, check what the lease says about appliance positions and works before relocating anything.
Follow the ownership.
The landlord’s appliance and its connection are generally theirs to maintain.
Your own machine in their property is typically yours to install — properly, with permission where the tenancy requires it.
The plumbing fabric, including supplies, valves and waste, is generally the landlord’s side either way.
Nearly a quarter of the borough rents privately, so it’s a routine question.
RHP tenants: check on 0800 032 2433 first.

An appliance installation in Richmond is judged twice: on day one, when anything that fills and spins looks fine — and years later, by the hose that didn’t fail, the valve that turned when it mattered, the waste that never smelled. The verified plumbers above install for the second judgement.
