Kitchen plumbing in Northampton

Why kitchen plumbing for a Northampton home?

Plenty of Northampton kitchens still have the sink where it was put decades ago, and moving it under the window or into an island is a common reason to call a plumber.

If your Northampton home has a solid concrete ground floor, a new sink or appliance position may mean cutting a channel for the waste, which is worth planning before the units arrive. We cover all of Northampton, including the NN1 postcode district, and travel out to neighbouring towns across Northamptonshire.

What is included in the work?

The exact scope is agreed after the survey, but a typical job in Northampton covers:

A survey of the stopcock, supply pipes, waste route and drain connection
Hot and cold supplies run to the new sink position
A cold feed for a boiling water tap tank or a fridge with a water dispenser
Dishwasher and washing machine supplies, with waste connections through suitable traps
Isolation valves on each tap and appliance feed for quick shut-off
Redundant pipes cut back to the live supply and capped, then a full leak check

What kind of kitchens do we fit in Northampton?

In and around Northampton, homes range across ironstone cottages, Victorian terraces, 1930s semis and post-war new town houses. 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.

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. Water across Northamptonshire is hard, so limescale on taps, sinks and boiling water taps is likely, and a scale-reducing filter is worth considering.

Building regulations, electrics and gas in Northampton

In England, kitchen pipework and fittings must meet the Water Supply (Water Fittings) Regulations 1999, which cover suitable materials, backflow protection and preventing waste or contamination of the supply. Connecting a sink to an existing waste or stack is routine, but a new connection to an underground drain, or a change to how waste water is discharged, involves building control. Gas pipework to a hob or cooker is separate work for a Gas Safe registered engineer.

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.

Planning ahead

Locate the stopcock in your Northampton home and check it turns before fitting day; a seized one may need replacing before the plumber can start.
If your Northampton home is on a water meter, a slow drip shows up on the bill, so look under the sink a week after the fit.
If your house in Northamptonshire has a solid floor, ask at the survey where a waste could run before you settle on an island sink.
Check your water pressure suits the tap you want, particularly a boiling water tap or a tall spray tap; the tap's instructions give its minimum.

Questions about kitchen plumbing in Northampton

How much does kitchen plumbing cost in Northampton?

Guide prices in Northampton are about £190 to £480 including VAT for connecting the sink, dishwasher and washing machine. 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 work near Northampton as well?

Yes. As well as Northampton itself, we cover the rest of Northamptonshire and nearby towns such as Wellingborough and Towcester. The process is the same wherever the kitchen is.

Can a kitchen sink be moved to a different wall?

Yes, usually. The supplies are the easy part; the waste decides it, because it needs a steady fall all the way to the stack or drain. On a suspended timber floor the pipe can often run between the joists, while on solid concrete a channel may need to be cut and filled. Where a fall cannot be achieved, a pumped waste is sometimes considered.

Why should every appliance have an isolation valve?

An isolation valve lets you shut off the water to one tap or appliance without turning off the whole house. If a dishwasher hose splits or a tap needs a new cartridge, you turn a small screw or lever under the sink and the rest of the home keeps running. Valves are fitted on the hot and cold tap feeds and on each appliance supply.

When does kitchen plumbing need building control?

Most kitchen plumbing does not. Replacing a sink, adding appliance connections and rerouting supply pipes inside the kitchen are routine. A new connection to an underground drain, or a change in how waste water is discharged, needs building control approval in England, Wales and Northern Ireland, or a building warrant in Scotland. Every fitting must also meet the water fittings rules for your nation.
