Kitchen plumbing in Belfast

Why do people in Belfast choose kitchen plumbing?

When a kitchen in Belfast goes from a closed room to an open-plan space, the sink and dishwasher often move to a new wall with new waste runs.

Plenty of Belfast 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. Kitchens in every part of Belfast are covered, and the survey visit is free wherever you are in County Antrim.

What does the job involve?

Every kitchen is different, so we confirm the scope in writing. Most jobs of this kind include:

Hot and cold supplies run to the new sink position
Radiators moved or replaced so they clear the new units
Waste pipes laid to a steady fall, with an access point for clearing blockages
A survey of the stopcock, supply pipes, waste route and drain connection
Redundant pipes cut back to the live supply and capped, then a full leak check
Isolation valves on each tap and appliance feed for quick shut-off

Kitchens in homes around Belfast

You will find red-brick terraces, Victorian villas, post-war estate houses and rural bungalows throughout County Antrim. Red-brick terraces in Belfast often have a narrow kitchen in the return, while estate houses and rural bungalows tend to have a separate kitchen with room for a table.

Terraced streets with entries at the back, city flats with booked lifts and country lanes can each affect deliveries, so the route for worktops is checked at the survey. Mains water across most of County Antrim is soft, so limescale is less of a problem and taps and boiling water taps tend to stay cleaner.

Do you need approval for kitchen plumbing in Belfast?

In Northern Ireland, supplies and fittings must comply with the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009. Reconnecting a sink or appliance to the existing waste is routine, whereas new connections to underground drains, or changing how waste water is discharged, need approval from the council's building control service under the Building Regulations (Northern Ireland) 2012. Gas work, including the pipe to a hob, is carried out only by a Gas Safe registered engineer.

Listed buildings and conservation areas in older parts of Belfast and the county towns may need consent for new vents, and apartment owners usually need management consent.

Tips before you start

Ask for supplies and wastes to be positioned to suit each appliance's instructions, so hoses are short and do not kink.
If your Belfast home is on a water meter, a slow drip shows up on the bill, so look under the sink a week after the fit.
Ask for an access point on the waste near the sink, so a future blockage can be cleared without taking a unit out.
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.

Questions about kitchen plumbing in Belfast

How much does kitchen plumbing cost in Belfast?

Guide prices in Belfast are about £180 to £440 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.

Yes. We work across Belfast, including the BT1, BT2, BT3, BT4, BT5 and BT6 postcode districts, and nearby towns such as Castlereagh and Newtownabbey. Book a free survey visit and we will arrange a time that suits you.

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.

What plumbing does a boiling water tap need?

A boiling water tap needs a cold supply to a tank under the sink, usually through a filter, plus an electrical socket or spur for the tank. Some models also take hot and cold feeds for the mixer side. The tank uses cupboard space, so the sink unit is planned around it, and the tap's minimum water pressure is checked against your supply.

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.
