Underfloor Heating in South Wales

Electric underfloor heating is one of the most popular bathroom and kitchen upgrades in South Wales homes — and for good reason. Stepping onto a warm tiled floor on a cold morning is a small luxury that makes a big difference to daily comfort. Electric underfloor heating systems are also more energy-efficient than many people expect when used with a programmable thermostat, which limits heating to the periods when the room is actually in use.

Our electricians install electric underfloor heating systems in homes throughout South Wales. We work with mat-based systems for tiling directly over, as well as loose-cable systems for more flexible layouts. We advise on the correct heat output per square metre for your specific room and floor covering, ensure that adequate floor insulation is in place to maximise efficiency and prevent heat loss downward, and install a high-quality programmable thermostat — including smart thermostat options for app and voice control.

Electric underfloor heating is particularly well suited to bathrooms, en-suites, wetrooms, and kitchen floors. It is also increasingly popular in open-plan living spaces and hallways. The system is completely invisible once installed — there are no visible radiators or pipework, which creates a cleaner aesthetic and frees up wall space. Combined with an appropriate LED lighting scheme, underfloor heating as part of a bathroom renovation delivers a genuinely luxurious result.

The electrical installation work involves running a dedicated circuit from your consumer unit to the thermostat position, connecting the underfloor heating mat or cable, and commissioning the thermostat. All work is carried out to BS 7671 standards and a Part P compliance certificate is issued on completion. We typically work alongside your tiler or flooring contractor and coordinate the installation so that the tiling or flooring can proceed immediately after the mat is laid.

Underfloor Heating FAQs

How much does underfloor heating cost to run?
Electric underfloor heating is efficient when controlled by a programmable thermostat that only heats the floor during occupied periods. A typical bathroom running for 1–2 hours per day costs just a few pence — the exact cost depends on your electricity tariff and the area of the room.
Can underfloor heating go under any floor type?
Most floor types are compatible, including tile, stone, luxury vinyl tile (LVT), and engineered wood. Deep pile carpets and solid wood flooring are generally not recommended as they act as insulators and reduce efficiency. We will advise on compatibility during the survey.
How long does installation take?
A bathroom underfloor heating installation typically takes one day for the electrical work. The overall project timeline depends on the tiler's schedule, as tiling must follow immediately after the mat is laid.
Do I need to insulate the floor before installing underfloor heating?
Yes — underfloor insulation is strongly recommended to prevent heat loss downward and to maximise the efficiency of the system. We advise on the correct insulation board product for your subfloor type during the survey.
Can I install underfloor heating in an upstairs bathroom?
Yes. Electric underfloor heating mats are thin and add only a few millimetres to floor height, making them ideal for bathrooms on any floor level. There is no requirement for pipework or a wet system, which makes electric UFH simpler to retrofit.
What thermostat options are available?
We offer programmable digital thermostats, touch-screen thermostats, and smart thermostats with app and voice control. A programmable thermostat is essential for energy-efficient use — we always recommend fitting one as part of the installation.
Can underfloor heating be the primary heat source for a room?
In well-insulated rooms with appropriate output, yes. In bathrooms and smaller spaces, electric underfloor heating can often serve as the sole heat source. In larger or poorly insulated rooms, it is better suited as supplementary heating alongside a radiator or other primary heat source.
