Sink and tap installation in Westminster

Is sink and tap installation right for your Westminster kitchen?

A Westminster 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.

If a new dishwasher or washing machine is going next to the sink in your Westminster home, the trap and waste connections usually need changing as well. If your home is in Westminster or close by in Pimlico or Chelsea, the same survey, quote and fitting process applies.

What kind of kitchens do we fit in Westminster?

In and around Westminster, homes range across 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.

Do you need approval for sink and tap installation in Westminster?

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.

Practical advice for Westminster homeowners

For a ceramic farmhouse-style sink in your Westminster kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.
Before buying a boiling water tap for your Westminster home, check its minimum water pressure and how much space it needs in the sink cupboard.
Empty the sink cupboard before fitting day, and plan where cleaning products will go while the waste, trap and valves are being changed.
Moving the sink means new supply and waste runs, so check the waste can fall properly to the drain or stack from the new position.

Questions about sink and tap installation in Westminster

How much does sink and tap installation cost in Westminster?

Guide prices in Westminster are about £260 to £520 including VAT for plumbing in a new sink and tap. The final price depends on the size of the kitchen and what is moving, and is set out in an itemised written quote.

Do you work near Westminster as well?

Yes. As well as Westminster itself, we cover the rest of Greater London and nearby towns such as Pimlico and Chelsea. The process is the same wherever the kitchen is.

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.

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.
