1. Foil Underfloor Heating

Foil underfloor heating is one of the best options for laminate and engineered wood floors. It offers a clean, dry installation, low build height and quick response time, making it especially useful in renovation projects.

I want to buy foil underfloor heating. Do I need underlay or insulation with foil heating?
Yes — you should use suitable insulation boards or insulated underlay below the foil to reduce heat loss into the subfloor. You can refer to our Underfloor Heating Insulation Guide as well as our Parador Underlay Guide for more detailed information. If the final floor is vinyl, carpet or linoleum, you’ll usually also need overlay boards above the foil.

3. StickyMat / Heating Mats

Heating mats are one of the easiest ways to install electric underfloor heating beneath tiles. They are especially popular in bathrooms, ensuites and kitchens because the cable is pre-spaced for fast, tidy fitting.

Do I need underlay with StickyMat?
Not underlay in the floating-floor sense. For best performance, you usually want insulation boards below the mat, then tile adhesive or levelling compound above, depending on the system and subfloor.

  • Flexible adhesive or levelling compound
  • Suitable tiled floor finish

6. In-Screed Electric Underfloor Heating

In-screed systems are designed for new builds, extensions or major renovation projects where the heating cable is laid into a screed layer. They are ideal when you want a durable, whole-floor heating solution with excellent long-term heat distribution.

Do I need underlay with in-screed systems?
Not underlay — but insulation below the screed build-up is extremely important. In-screed systems rely heavily on correct insulation and planning.

Buyer FAQs About Electric Underfloor Heating

Which electric underfloor heating system is best to buy?

It depends on your floor finish and room. For tiled bathrooms and en-suites, mats, loose wire and decoupling systems are usually the best fit. For laminate and engineered wood, foil or carbon film are usually the better route. For new builds and extensions, in-screed systems are often strongest.

Which system is cheapest to run?

In day-to-day use, all electric systems convert electricity into heat very efficiently. The biggest difference in real-world running cost usually comes from insulation, thermostat control, room heat loss and correct build-up. Foil and carbon film are often cost-effective for dry floating-floor builds, while StickyMat, DCM-PRO and loose wire work very well in tiled rooms with proper insulation.

Do I need insulation boards?

In most cases, yes. Insulation below the system improves warm-up times and reduces heat loss into the subfloor. Our Insulation Board Buyers Guide explains this fully.

Can one thermostat control more than one heating zone?

Yes, one thermostat can control multiple underfloor heating mats or circuits, provided they are all in the same room or zone and the total load is within the thermostat rating. If you want different rooms at different temperatures, each zone should have its own thermostat.

Are underfloor heating thermostats universal?

Many are compatible across brands. In many cases, a Flexel thermostat can work with Warmup heating products and vice versa, provided the thermostat can handle the electrical load and the sensor compatibility is correct. Always check voltage, maximum load and installation requirements.

Can I install electric underfloor heating upstairs?

Yes. Foil and carbon film systems are often especially suitable for upper floors with floating floor finishes.

Can I use foil or carbon film on stairs?

We do not recommend foil heating or carbon film on stairs. These systems are designed for large, flat floating floor areas, not stepped surfaces. If a staircase must be heated, a permanently bonded tiled-type solution such as a loose-wire system would generally be the only sensible electric option, and it needs careful planning. For most projects, it is better to heat the landing rather than the individual stairs.

Can electric underfloor heating be used in bathrooms?

Yes, but the best system depends on the floor finish and whether the room is a standard bathroom or a wet room. Tiled systems such as Flexel EcoFloor, Warmup StickyMat and Warmup DCM-PRO are usually the better option for wet areas. Foil heating can work in some bathroom builds with the correct flooring and safety requirements, but it is not the best fit for every bathroom.

What else do I need to buy with my underfloor heating?

That depends on the system. Many projects also need insulation, a thermostat, a floor sensor, tape, clips, fixing strips, overlay boards, vapour barrier or connection accessories. The “Everything You Need” sections above are designed to make that clearer so you can buy with more confidence.

Can I buy flooring that works with the heating system too?

Yes. That can make choosing the right build-up much easier. For example: laminate, engineered wood and waterproof vinyl can all be part of a well-planned project when the correct system is chosen.

Is electric underfloor heating worth it in the UK?

Yes, especially in well-insulated homes. Electric underfloor heating provides even radiant warmth across the floor, removes the need for radiators, and works well in kitchens, bathrooms, extensions and renovated spaces. Running costs depend mostly on insulation levels and thermostat control rather than the specific system.

What electric underfloor heating system is best for laminate flooring?

For laminate floors, foil heating systems and carbon film systems are usually the best options because they install dry beneath floating floors and maintain a low floor build-up. Our foil heating guide explains this in detail.

What electric underfloor heating is best for bathrooms?

Bathrooms normally use tiled heating systems such as StickyMat heating mats, loose wire heating or DCM-PRO decoupling systems. These systems sit within tile adhesive and provide excellent heat transfer through ceramic or stone tiles.

How much does electric underfloor heating cost to run in the UK?

Running costs vary depending on insulation and room size, but typical electric underfloor heating costs range from around £0.10 to £0.60 per hour depending on system size. Our detailed guides break down real examples for each system including foil heating, carbon film and loose wire systems.

Can electric underfloor heating replace radiators?

In many rooms it can. Electric underfloor heating is commonly used as the primary heating system in bathrooms, kitchens and smaller spaces. In larger rooms it can also act as the main heating system when the room is properly insulated.

Which electric underfloor heating system is easiest to install?

Heating mats such as StickyMat systems are usually the fastest to install because the cable is pre-spaced on a mesh backing. Loose wire systems take slightly longer but offer greater flexibility for awkward layouts.
