Sink and tap installation in Portsmouth

Thinking about sink and tap installation in Portsmouth?

A Portsmouth kitchen with the sink in an awkward corner may work better with the sink under the window or on an island, which means new supplies and a new waste run.

If a new dishwasher or washing machine is going next to the sink in your Portsmouth home, the trap and waste connections usually need changing as well. Our Hampshire coverage reaches every part of Portsmouth (PO5) and out towards Southsea.

Fitting kitchens in older and newer Portsmouth homes

In and around Portsmouth, homes range across Victorian terraces, 1930s semis, post-war estate houses and thatched and brick cottages. 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.

Regulations for kitchen work in Portsmouth

Replacing a sink and tap needs no approval in England, but the plumbing should meet the Water Supply (Water Fittings) Regulations 1999, including isolation valves and backflow protection. Connecting to an existing waste is routine, while a new connection to an underground drain involves building control. A new spur for a boiling water tap on an existing kitchen circuit is not notifiable under Part P, but it must meet BS 7671.

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.

Worth knowing before the fit

Find the stopcock in your Portsmouth home before the plumber arrives and check it turns off fully, as older stopcocks can stick or let water past.
Before buying a boiling water tap for your Portsmouth home, check its minimum water pressure and how much space it needs in the sink cupboard.
Empty the sink cupboard before fitting day, and plan where cleaning products will go while the waste, trap and valves are being changed.
An undermount sink in a stone worktop is cut and polished by the fabricator, so choose the sink before the worktops are templated.

Questions about sink and tap installation in Portsmouth

How much does sink and tap installation cost in Portsmouth?

Guide prices in Portsmouth are about £230 to £460 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.

Can you measure up in Portsmouth before quoting?

Yes. Every quote starts with a free, no-obligation survey visit to your home in Portsmouth. We measure the room, check the walls, floor and service positions, then send an itemised written quote.

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.

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.
