Why do people in Greater London choose sink and tap installation?

A Greater London kitchen with the sink in an awkward corner may work better with the sink under the window or on an island, which means new supplies and a new waste run.

Landlords in Greater London often swap tired sinks and taps between tenancies, choosing hard-wearing finishes and accessible valves so that later repairs are quick and cheap.

What does sink and tap installation in Greater London include?

Your written quote lists everything included. For sink and tap installation, that normally means:

  • New sink fitted, sealed and connected to the existing supplies and waste
  • Isolation valves on the hot and cold supplies, with flexible tap tails connected
  • Waste, overflow and trap fitted, with dishwasher and washing machine waste connections
  • Inset sink cut-outs made on site in laminate and wood worktops
  • Ceramic farmhouse-style sinks set on a suitable supporting base unit and sealed
  • Boiling water tap fitted with its tank, filter and power supply in the cupboard
  • Sink moved to a new position with new supply and waste runs
  • Every joint leak tested, with water flow and drainage checked before handover

How much does sink and tap installation cost in Greater London?

The figures below are guide prices for Greater London, including VAT and adjusted for typical costs across London. The fixed price comes after we have measured up. Labour in London generally costs more than the UK average, which lifts these ranges a little.

Kitchens in homes across Greater London

The housing mix across Greater London includes Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis, so no two kitchen fits are quite alike. 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.

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. Permit parking, red routes and flats without lifts are common, so parking suspensions, stair carries and lift bookings may need arranging before delivery day.

Opening a narrow galley into the dining room or side return is one of the most common terrace projects in London. Leasehold flats often call for a full kitchen in a small space, worked around building rules on noise, working hours and waste.

Rules for sink and tap installation in Greater London

Replacing a sink and tap needs no approval in England, but the plumbing should meet the Water Supply (Water Fittings) Regulations 1999, including isolation valves and backflow protection. Connecting to an existing waste is routine, while a new connection to an underground drain involves building control. A new spur for a boiling water tap on an existing kitchen circuit is not notifiable under Part P, but it must meet BS 7671.

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 start

  • Keep isolation valves reachable under the sink, so the tap can be serviced or a leak stopped without turning off the whole house supply.
  • An undermount sink in a stone worktop is cut and polished by the fabricator, so choose the sink before the worktops are templated.
  • If a dishwasher or washing machine sits next to the sink, plan their waste connections and the trap layout together with the sink.
  • Check a boiling water tap's minimum water pressure and cupboard space before buying, as the tank, filter and power supply all sit under the sink.
  • Ask for the dishwasher and washing machine hoses to be routed so they cannot kink behind the units once the appliances are pushed back into place.
  • For a ceramic farmhouse-style sink in your Greater London kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.

Questions about sink and tap installation in Greater London

How much does sink and tap installation cost in Greater London?

For plumbing in a new sink and tap, budget around £260 to £520 including VAT in Greater London. That reflects typical costs in London; we confirm the actual figure in writing once we have measured up.

Do you cover the whole of Greater London?

Yes. We carry out sink and tap installation across Greater London, including Brent, Islington, Westminster and Bexley. Every job starts with a free survey visit and an itemised written quote.

Do I need isolation valves under my kitchen sink?

They are strongly advised, and we fit them as standard. An isolation valve on each supply to the tap, and on each appliance supply, lets you turn off the water to one fitting without shutting off the whole house. That makes changing a tap cartridge or dealing with a leak far simpler. The valves are left where they can still be reached once the cupboard is in use.

Can a dishwasher and washing machine drain through the sink waste?

Yes, in most kitchens. The sink trap can take an appliance connection on a spigot, or a separate standpipe can be fitted. The appliance hose needs to rise to the height its manufacturer specifies before it drops to the waste, so dirty water cannot siphon back. Two appliances can usually share a double-spigot trap, which we plan with the sink.

What is the difference between an inset and an undermount sink?

An inset sink drops into a cut-out from above, with its rim resting on the worktop, and suits laminate, wood and stone. An undermount sink is fixed beneath the worktop so the edge of the cut-out is exposed, which usually calls for a solid, water-resistant material such as stone or solid surface. Undermount cut-outs in stone are cut and polished by the fabricator.
