Kitchen plumbing in Greenwich
Kitchen plumbing for Greenwich homes: supplies, isolation valves and wastes for the sink, dishwasher and washing machine in a new layout. Every job starts with a free survey visit and a written quote.

Who usually needs kitchen plumbing in Greenwich?
When a kitchen in Greenwich goes from a closed room to an open-plan space, the sink and dishwasher often move to a new wall with new waste runs.
In older properties across Greater London, kitchen pipework has often been extended many times over; a refit is the chance to replace it with a tidy, accessible layout. Greenwich sits about 6 miles east of Westminster, and our Greater London coverage takes in everything in between.
What does kitchen plumbing in Greenwich include?
Your written quote lists everything included. For kitchen plumbing, that normally means:
- Dishwasher and washing machine supplies, with waste connections through suitable traps
- Hot and cold supplies run to the new sink position
- A cold feed for a boiling water tap tank or a fridge with a water dispenser
- Redundant pipes cut back to the live supply and capped, then a full leak check
- A survey of the stopcock, supply pipes, waste route and drain connection
- Radiators moved or replaced so they clear the new units
What should you budget for kitchen plumbing in Greenwich?
These guide ranges include VAT at 20% and are adjusted for prices in London. We confirm your price in writing after a free survey visit. Prices in London usually run above the national guide, mainly because labour and parking cost more.

Local homes and their kitchens
Typical homes in this part of Greater London include Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis. Victorian terraces often have a narrow galley beside the side return, while conversion flats and mansion blocks usually fit the kitchen into a small room or along one living-room wall.
Permit parking, red routes and flats without lifts are common, so parking suspensions, stair carries and lift bookings may need arranging before delivery day. London's mains water is hard, so limescale builds quickly on taps and boiling water taps, and a scale-reducing filter is worth planning in.
Building regulations, electrics and gas in Greenwich
In England, kitchen pipework and fittings must meet the Water Supply (Water Fittings) Regulations 1999, which cover suitable materials, backflow protection and preventing waste or contamination of the supply. Connecting a sink to an existing waste or stack is routine, but a new connection to an underground drain, or a change to how waste water is discharged, involves building control. Gas pipework to a hob or cooker is separate work for a Gas Safe registered engineer.
Conservation areas are widespread across London, so a new extractor vent on a front wall may need permission, and leaseholders usually need the freeholder's written consent first.
Before you book kitchen plumbing in Greenwich
- Measure the cupboard under your sink before buying a boiling water tap for your Greenwich kitchen, as the tank and pipework need clear space.
- Locate the stopcock in your Greenwich home and check it turns before fitting day; a seized one may need replacing before the plumber can start.
- Ask for an access point on the waste near the sink, so a future blockage can be cleared without taking a unit out.
- Check your water pressure suits the tap you want, particularly a boiling water tap or a tall spray tap; the tap's instructions give its minimum.
Questions about kitchen plumbing in Greenwich
How much does kitchen plumbing cost in Greenwich?
For connecting the sink, dishwasher and washing machine, budget around £260 to £650 including VAT in Greenwich. That reflects typical costs in London; we confirm the actual figure in writing once we have measured up.
Which parts of Greenwich do you work in?
All of them. Our Greater London coverage takes in the whole of Greenwich, including the SE10 postcode district, as well as surrounding towns such as New Cross. If you are unsure, send us your postcode.
What plumbing does a boiling water tap need?
A boiling water tap needs a cold supply to a tank under the sink, usually through a filter, plus an electrical socket or spur for the tank. Some models also take hot and cold feeds for the mixer side. The tank uses cupboard space, so the sink unit is planned around it, and the tap's minimum water pressure is checked against your supply.
Why should every appliance have an isolation valve?
An isolation valve lets you shut off the water to one tap or appliance without turning off the whole house. If a dishwasher hose splits or a tap needs a new cartridge, you turn a small screw or lever under the sink and the rest of the home keeps running. Valves are fitted on the hot and cold tap feeds and on each appliance supply.
When does kitchen plumbing need building control?
Most kitchen plumbing does not. Replacing a sink, adding appliance connections and rerouting supply pipes inside the kitchen are routine. A new connection to an underground drain, or a change in how waste water is discharged, needs building control approval in England, Wales and Northern Ireland, or a building warrant in Scotland. Every fitting must also meet the water fittings rules for your nation.
