What kind of kitchens do we fit in Derry/Londonderry?

The housing mix across County Londonderry includes red-brick terraces, Georgian townhouses, rural bungalows and post-war estate houses, so no two kitchen fits are quite alike. Terraced houses in the city and in Coleraine often have a narrow kitchen in the return, while rural bungalows tend to have a larger kitchen with space for dining.

Steep streets in the city, terraces with limited parking and long country roads can each affect deliveries, so the route for worktops is checked at the survey. County Londonderry's mains water is generally soft, so limescale is rarely a big problem and taps and boiling water taps tend to stay cleaner.

What rules apply to sink and tap installation in Derry/Londonderry?

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.

The historic walled city is a conservation area with many listed buildings, so new external vents or changes to historic features there may need consent first.

Tips before you start

For a ceramic farmhouse-style sink in your Derry/Londonderry kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.
Empty the sink cupboard before fitting day, and plan where cleaning products will go while the waste, trap and valves are being changed.
Choose the sink before stone worktops are templated in your Derry/Londonderry kitchen, so the fabricator can cut and polish the undermount opening to suit it.
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 Derry/Londonderry

How much does sink and tap installation cost in Derry/Londonderry?

Guide prices in Derry/Londonderry are about £180 to £350 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 work near Derry/Londonderry as well?

Yes. As well as Derry/Londonderry itself, we cover the rest of County Londonderry and nearby towns such as Strabane and Limavady. The process is the same wherever the kitchen is.

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.

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.
