Best electric foil underfloor heating
Updated: October 2026
You are looking at nine amazon.co.uk foil and film listings and you want one name, not a slogan. Best electric foil underfloor heating, in this set, means one of two rules: the highest star score, or the lowest pounds per stated square metre among the 230 V kits that include a thermostat. Neither rule is a laboratory test. The [electric underfloor heating foil comparison](/hub/heating/underfloor-heating-foil) holds the prices, star lines, and named floor finishes. If you buy through our links, a qualifying purchase can earn us a commission at no extra cost to you.

Highest star score in this set
The top pick on the star rule is the Adept dial-thermostat foil kit, ASIN B017T2NZE4, at £54.99. The amazon.co.uk line is 4.8 out of 5 from 16 reviews, the highest star score in this set. The title includes a white dial manual thermostat and says you choose the size, so the square metres are not fixed on the row. Laminate or engineered wood is named. Carpet is not. Sixteen reviews is a small sample.
A UK review dated 13 December 2023 describes effective heat under LVT, with earthing checked on a test meter, and a mini Wi-Fi switch because the dial has no remote control. A review dated 29 March 2020 says the back box was extra. If you need the square metres printed before you order, use the value rule below. The underfloor heating foil buying guide puts supply, finish, and area in order before either rule matters.
Lowest price per stated square metre
The best value on the second rule is the Adept 10 m² foil kit, ASIN B07V397957, at £164.99. Divide that shelf price by the stated 10 m² and you get about £16.50 a square metre. In this set that is below the 3 m² kit at about £30, the 3.5 m² touchscreen kit at about £29, and the 7 m² touchscreen kit at about £19. Those rates use only kits that print an area and include a thermostat. They are not a survey of every foil mat on amazon.co.uk.
The kit is 140 W/m² with a white programmable thermostat, on the shared 4.5 from 20 line, including a warm hall and conservatory on 18 January 2024 and a later floor-probe fault. This listing states 1 mm thickness, while the 3 m² row states 0.5 cm. £164.99 does not include insulation or the electrician’s time. Buy this when the free floor is about 10 m² of laminate or engineered wood.
The 12 V film and the Minco pieces
The 12 V film, B07YN23JHC, has the largest count, 4.3 out of 5 from 66 reviews, at £109. That does not win the star rule, because 4.3 is below 4.8, and it does not win the value rule, because it is a vehicle film of about 0.5 m², not a 230 V room kit. Minco’s 50 cm by 1 m film is £25.99 with no thermostat stated and no review line. The 50 cm by 2 m film at £35.99 is the same kind of parts buy. Cheap per piece is not the best-value rule used here.
Touchscreen kits and the 140 W/m² line
The black touchscreen kits, 3.5 m² at £99.99 and 7 m² at £134.99, share 3.9 from 10. A display went blank in December 2023 after a September 2022 install, and a 17 August 2024 review describes four boxes and four thermostats for one room. HM140/7 at £129.99 prints a width, not an area. Warmup says 140 W/m² is adequate for most heating needs. That sentence is about Warmup’s systems, not a test of Adept. Section 9 of the Consumer Rights Act 2015 is the satisfactory-quality rule if a unit fails, not a best-of list. Carpet and tile claims are kept off these kits on the underfloor heating foil under laminate page.
Common questions
Which listing has the highest star score?
The Adept dial-thermostat foil kit, B017T2NZE4, shows 4.8 out of 5 from 16 amazon.co.uk reviews, at £54.99. That is the highest star score among the nine listings in this set. The white-thermostat rows sit at 4.5 from 20, the touchscreen rows at 3.9 from 10, and the 12 V film at 4.3 from 66. The two Minco films have no review line, so they have no star score to compare.
Which 230 V kit is cheapest per stated square metre?
The Adept 10 m² kit, B07V397957, is £164.99, about £16.50 for each stated square metre, with a white programmable thermostat. That is the lowest rate among the 230 V kits in this set that print an area and include a thermostat. The 3 m² and 3.5 m² kits cost more per stated square metre because the controller is spread over less floor. The dial kit cannot be ranked this way, because its title does not state the area.
Why not the 12 V film, which has 66 reviews?
Sixty-six reviews is the largest count in the set, and the score is 4.3, which is below the dial kit’s 4.8. The listing is a 12 V sheet of about 0.5 m² for caravans, motorhomes, campers, boats, and similar vehicles, at £109. It is the wrong comparison when you are heating a house room on 230 V. A larger review count does not change the supply.
Why not the Minco film at £25.99?
£25.99 buys 0.5 m² of film with no thermostat stated and no star line. The value rule counts only 230 V kits that include a thermostat and state an area. A controller bought separately can remove the saving. Buy Minco when you already have that controller and you only need the short length.
Is the touchscreen kit the best because it is programmable?
The touchscreen kits share 3.9 from 10, the weakest Adept line here. One review describes a display that went blank after the floor had been down for over a year. Programmable is a control type. It is not the star rule, and it is not the lowest pounds per stated square metre.
