Sink and tap installation in Pinner

What prompts sink and tap installation in Pinner?

If you are fitting new stone worktops in your Pinner kitchen, it is a natural point to change to an undermount sink cut and polished by the fabricator.

Plenty of people in Pinner replace a sink and tap on their own when the tap drips, the bowl is stained or the waste drains slowly, without touching the rest of the kitchen. Our Greater London coverage reaches every part of Pinner (HA5) and out towards Wealdstone.

What does the job involve?

Here is what usually goes into sink and tap installation, adjusted to your Pinner kitchen after we have measured it:

Every joint leak tested, with water flow and drainage checked before handover
Ceramic farmhouse-style sinks set on a suitable supporting base unit and sealed
Isolation valves on the hot and cold supplies, with flexible tap tails connected
Sink moved to a new position with new supply and waste runs
New sink fitted, sealed and connected to the existing supplies and waste
Waste, overflow and trap fitted, with dishwasher and washing machine waste connections

What kind of kitchens do we fit in Pinner?

You will find Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis throughout Greater London. 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.

Regulations for kitchen work in Pinner

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 Pinner homeowners

Choose the sink before stone worktops are templated in your Pinner kitchen, so the fabricator can cut and polish the undermount opening to suit it.
Check the tap's hole size against the sink or worktop before ordering, as some taps need a larger hole than an existing sink provides.
Find the stopcock in your Pinner home before the plumber arrives and check it turns off fully, as older stopcocks can stick or let water past.
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 Pinner

How much does sink and tap installation cost in Pinner?

Guide prices in Pinner 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.

Which parts of Pinner do you work in?

All of them. Our Greater London coverage takes in the whole of Pinner, including the HA5 postcode district, as well as surrounding towns such as Wealdstone. If you are unsure, send us your postcode.

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.

What do I need for a boiling water tap?

A boiling water tap needs a tank in the cupboard under the sink, usually a socket or fused spur to power it, and often a filter, particularly where the water is hard. Some models have a minimum water pressure, so check yours before buying. The tap also needs a correctly sized hole in the sink or worktop and enough clear cupboard space for the tank and pipework.

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.
