Local homes and their kitchens

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.

What rules apply to sink and tap installation in 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.

Worth knowing before the fit

Ask whether a boiling water tap for your kitchen in Greater London needs a filter, how often it should be changed and where it will sit in the cupboard.
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.
For a ceramic farmhouse-style sink in your Barnet kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.
If a dishwasher or washing machine sits next to the sink, plan their waste connections and the trap layout together with the sink.

Questions about sink and tap installation in Barnet

How much does sink and tap installation cost in Barnet?

Which parts of Barnet do you work in?

All of them. Our Greater London coverage takes in the whole of Barnet, including the EN5 postcode district, as well as surrounding towns such as East Barnet. If you are unsure, send us your postcode.

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.

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.
