Sink and tap installation in Northampton

Is sink and tap installation right for your Northampton kitchen?

Plenty of people in Northampton 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.

If you are fitting new stone worktops in your Northampton kitchen, it is a natural point to change to an undermount sink cut and polished by the fabricator. We work throughout Northampton (NN1) and across the wider Northamptonshire area.

What does the job involve?

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

Sink moved to a new position with new supply and waste runs
Ceramic farmhouse-style sinks set on a suitable supporting base unit and sealed
Inset sink cut-outs made on site in laminate and wood worktops
New sink fitted, sealed and connected to the existing supplies and waste
Waste, overflow and trap fitted, with dishwasher and washing machine waste connections
Boiling water tap fitted with its tank, filter and power supply in the cupboard

House types around Northampton and what they mean for a kitchen

You will find ironstone cottages, Victorian terraces, 1930s semis and post-war new town houses throughout Northamptonshire. Victorian terraces in Northampton and Kettering often have a long galley behind the back room, while post-war houses in Corby tend to have a compact rectangular kitchen.

Water across Northamptonshire is hard, so limescale on taps, sinks and boiling water taps is likely, and a scale-reducing filter is worth considering. Terraced streets with on-street parking can make unloading slow, and village houses on narrow lanes may need a smaller delivery vehicle for long worktops.

Regulations for kitchen work in Northampton

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.

Listed ironstone cottages and homes in village conservation areas may need listed building consent or planning permission for new vents or changes to historic fabric.

Before you book sink and tap installation in Northampton

Empty the sink cupboard before fitting day, and plan where cleaning products will go while the waste, trap and valves are being changed.
Ask whether a boiling water tap for your kitchen in Northamptonshire needs a filter, how often it should be changed and where it will sit in the cupboard.
For a ceramic farmhouse-style sink in your Northampton kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.
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 Northampton

How much does sink and tap installation cost in Northampton?

Guide prices in Northampton are about £190 to £390 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 cover all of Northampton?

Yes. We work across Northampton, including the NN1 postcode district, and nearby towns such as Wellingborough and Towcester. Book a free survey visit and we will arrange a time that suits you.

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 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.

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.
