Kitchen underfloor heating in Portsmouth

Is kitchen underfloor heating right for your Portsmouth kitchen?

People planning a heat pump in Hampshire sometimes add underfloor heating to the kitchen at the same time, while the old floor is already up and the room is empty.

If you are laying a new tiled floor in your Portsmouth kitchen anyway, that is the natural moment to put electric heating mats underneath it. Kitchens in every part of Portsmouth are covered, and the survey visit is free wherever you are in Hampshire.

What is included in the work?

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

A heating layout drawn to the kitchen plan, clear of units and appliances
Screed, overlay boards or levelling compound, left to cure before finishes
Insulation boards so the floor responds more quickly when the heating comes on
Door thresholds and plinth heights checked against the new floor build-up
Plinth heaters fitted under base units where wall space for a radiator is short
Electric mats or cables, or wet pipework connected through a manifold

What kind of kitchens do we fit in Portsmouth?

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.

Building regulations, electrics and gas in Portsmouth

In England, electric underfloor heating needs a supply and a thermostat. A new dedicated circuit is notifiable under Part P and is certified through a competent person scheme or building control, while a fused spur from an existing circuit is not notifiable in England but must still meet BS 7671 and be certified. A wet system is joined to your existing heating, and any work on a gas boiler is 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 book kitchen underfloor heating in Portsmouth

Photograph the heating mats or pipes before the floor goes down, so you know where they run if you ever need to drill into it.
Keep rugs light in your Portsmouth kitchen-diner; heavy rugs and thick mats hold heat in the floor instead of letting it warm the room.
If your Portsmouth home has a suspended timber floor, ask how the heating will be supported and insulated between the joists.
Heat is laid only across the open floor, not under fitted units or appliances, so the heated area is smaller than the room.

Questions about kitchen underfloor heating in Portsmouth

How much does kitchen underfloor heating cost in Portsmouth?

For electric underfloor heating for a kitchen floor, budget around £690 to £1,700 including VAT in Portsmouth. That reflects typical costs in the South East; we confirm the actual figure in writing once we have measured up.

Do you cover all of Portsmouth?

Yes. We work across Portsmouth, including the PO5 postcode district, and nearby towns such as Southsea and Gosport. Book a free survey visit and we will arrange a time that suits you.

Can underfloor heating go under kitchen units?

No, it is not usually laid under fitted units, plinths or appliances. Heat trapped beneath a cabinet or appliance can build up and damage the system or the floor, and it warms nothing useful. The heating layout follows the kitchen plan, covering the open floor, walkways and any dining area, which is why the units are set out before the heating goes down.

Is electric or wet underfloor heating better for a kitchen?

It depends on the floor and the heating you already have. Electric mats are thin, quick to lay and suit a single kitchen floor during a refit. Wet systems use warm water from the boiler or heat pump, need more floor depth and a manifold, and make more sense when a larger area, such as a whole kitchen-diner floor, is being relaid at the same time.

Which floor finishes work with underfloor heating?

Porcelain and ceramic tiles work well, because they conduct heat and cope with temperature changes. Luxury vinyl tiles and engineered wood can also be used, but their manufacturers set a maximum surface temperature, so the thermostat needs a floor sensor and a limit set to match. Thick underlays and rugs reduce the heat reaching the room, so check the finish's installation guidance before ordering.
