Who usually needs sink and tap installation in Welling?
If a new dishwasher or washing machine is going next to the sink in your Welling home, the trap and waste connections usually need changing as well.
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. Welling sits about 11 miles east of Westminster, and our Greater London coverage takes in everything in between.

Fitting kitchens in older and newer Welling homes
In and around Welling, 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.
Regulations for kitchen work in Welling
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
- 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 Welling kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.
- 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.
- 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 Welling
How much does sink and tap installation cost in Welling?
Guide prices in Welling 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.
Can you measure up in Welling before quoting?
Yes. Every quote starts with a free, no-obligation survey visit to your home in Welling. We measure the room, check the walls, floor and service positions, then send an itemised written quote.
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 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.
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.
