Kitchen plumbing in Hampshire
Our kitchen plumbing work covers the whole of Hampshire, including Southampton, Portsmouth and Basingstoke.
Is kitchen plumbing right for your Hampshire kitchen?
When a kitchen in Hampshire goes from a closed room to an open-plan space, the sink and dishwasher often move to a new wall with new waste runs.
Landlords in Hampshire often ask for every appliance to have its own isolation valve, so a tenant can stop a leak quickly without turning off the whole property.
What does kitchen plumbing in Hampshire include?
Here is what usually goes into kitchen plumbing, adjusted to your Hampshire kitchen after we have measured it:
- A survey of the stopcock, supply pipes, waste route and drain connection
- Hot and cold supplies run to the new sink position
- Isolation valves on each tap and appliance feed for quick shut-off
- Dishwasher and washing machine supplies, with waste connections through suitable traps
- Waste pipes laid to a steady fall, with an access point for clearing blockages
- Radiators moved or replaced so they clear the new units
- A cold feed for a boiling water tap tank or a fridge with a water dispenser
- Redundant pipes cut back to the live supply and capped, then a full leak check
How much does kitchen plumbing cost in Hampshire?

Kitchens in homes across Hampshire
Across Hampshire you will often find Victorian terraces, 1930s semis, post-war estate houses and thatched and brick cottages, and each shapes the kitchen differently. Terraces in Southampton and Portsmouth often have a narrow back kitchen, while post-war estate houses tend to have a compact rectangular room suited to an L-shape.
Water across Hampshire is mostly hard, largely from chalk sources, so limescale on taps and boiling water taps is common and a filter can help. Dense terraced streets can be very tight for parking, and New Forest lanes and village roads may limit the size of delivery vehicle.
Terraced houses often have a small back kitchen behind the dining room, and owners frequently knock through to make one family space. Village cottages bring thick walls, low beams and sometimes a range cooker, all of which shape the layout.
Rules for kitchen plumbing in Hampshire
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.
Homes within the New Forest or South Downs national parks, listed cottages and conservation areas may need consent for a new extractor vent or alterations to historic features.
Before you start
- Find out whether the kitchen floor is suspended timber or solid concrete, as a waste run across concrete means cutting and reinstating the floor.
- Put the dishwasher next to the sink so its supply and waste stay short, easy to reach and less likely to block.
- If a radiator sits where new units will go, decide early whether to move it, swap it for a tall one or fit a plinth heater.
- Ask for redundant pipes to be removed back to the live supply rather than left behind units, where they can hold stale water or leak.
- Ask for an access point on the waste near the sink, so a future blockage can be cleared without taking a unit out.
- Plan a day or two without a working sink in your Hampshire kitchen, and fill a few large bottles before the water goes off.
Questions about kitchen plumbing in Hampshire
How much does kitchen plumbing cost in Hampshire?
Guide prices in Hampshire are about £230 to £580 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 cover the whole of Hampshire?

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.
What happens to the old pipes during a kitchen refit?
Pipes that will no longer serve anything are cut back to the nearest live pipe and capped, rather than left as long dead ends behind the new units. Water sitting in an unused length of pipe can go stale, and a forgotten joint can leak where nobody will see it. Old wastes are removed or sealed so they cannot let drain smells back into the room.
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.
