Sink and tap installation in Friern Barnet

When does sink and tap installation make sense in Friern Barnet?

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

People in Friern Barnet with low water pressure sometimes find a new tap disappointing, so checking the pressure before choosing a tap or boiling water tap saves trouble later. Friern Barnet sits about 8 miles north of Westminster, and our Greater London coverage takes in everything in between.

House types around Friern Barnet and what they mean for a kitchen

Across Greater London you will often find Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis, and each shapes the kitchen differently. 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.

Building regulations, electrics and gas in Friern Barnet

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.

Planning ahead

Choose the sink before stone worktops are templated in your Friern Barnet kitchen, so the fabricator can cut and polish the undermount opening to suit it.
For a ceramic farmhouse-style sink in your Friern Barnet 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 Friern Barnet home, check its minimum water pressure and how much space it needs in the sink cupboard.
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 Friern Barnet

How much does sink and tap installation cost in Friern Barnet?

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.

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.
