Sink and tap installation in Belfast

Is sink and tap installation right for your Belfast kitchen?

Homeowners across County Antrim adding a boiling water tap often need a socket or spur in the sink cupboard, a filter and space for the tank planned in.

Some Belfast households choose a deep ceramic farmhouse-style sink for a new kitchen and need the base unit and worktop planned around its weight and size. Homes right across Belfast are covered, as are nearby places such as Castlereagh, Newtownabbey and the villages in between.

Fitting kitchens in older and newer Belfast homes

Typical homes in this part of County Antrim include red-brick terraces, Victorian villas, post-war estate houses and rural bungalows. 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.

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. 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.

Regulations for kitchen work in Belfast

In Northern Ireland, a like-for-like sink and tap replacement needs no building control application, and water fittings should meet the water fittings regulations that apply there. New connections to underground drains go to council building control. There is no Part P-style notification for domestic electrics, but a supply for a boiling water tap should be installed and tested to BS 7671 and certified.

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

For a ceramic farmhouse-style sink in your Belfast kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.
Ask for the dishwasher and washing machine hoses to be routed so they cannot kink behind the units once the appliances are pushed back into place.
Before buying a boiling water tap for your Belfast home, check its minimum water pressure and how much space it needs in the sink cupboard.
Keep isolation valves reachable under the sink, so the tap can be serviced or a leak stopped without turning off the whole house supply.

Questions about sink and tap installation in Belfast

How much does sink and tap installation cost in Belfast?

For plumbing in a new sink and tap, budget around £180 to £350 including VAT in Belfast. That reflects typical costs in Northern Ireland; we confirm the actual figure in writing once we have measured up.

Do you cover all of Belfast?

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.

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.

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.

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.
