A small tiled room that needs the thermostat in the box

If your free floor is about two square metres after the bath and the WC, and you want 200 W/m² with the controller in the same delivery, the HEATIT kit with ET-81 at £99.99 is the clearest complete row here. The listing says one mat and one thermostat, prints 400 W and 1.7 A on 230 V, and allows a shower room while excluding pools and outdoor use. Amazon.co.uk shows 4.4 from 36 reviews. Skip it if the free floor is closer to three square metres. The cable cannot be shortened, and the roll is 0.5 m by 4 m. Skip it if you already own a floor-probe thermostat. The 1.5 m² HEATIT at £33.24 buys area, not a controller. Measuring sits on the electric underfloor heating buying guide.

A five-square-metre floor at 200 W/m² with a controller

When the free floor is about five square metres and you want 200 W/m² with a named thermostat, the HEATIT kit with ET-84 at £142.49 matches the label: 1000 W, 4.3 A, 0.5 m by 10 m, with the same wet-room wording as the smaller kit. Skip it if you need review depth before tile adhesive. The capture shows 5.0 from one rating and no review body. Skip it if 150 W/m² on a well-insulated floor is enough and you will buy a thermostat separately. The five-square-metre 150 W/m² HEATIT at £46.54 is mat-only, with five reviews. The 150 W versus 200 W page explains output.

A mat only, when you will buy the thermostat separately

Several rows assume you will pair the mesh with your own floor-probe thermostat. Bolisi’s three-square-metre mat at £51.99 includes a two-metre sensor tube and sells the thermostat separately. The HEATIT three-square-metre minimat at £42.99 and the 1.5 m² row at £33.24 are coloured Only Minimat-d. The 4.6 from 57 ratings is shared between those two sizes. MINCOHEAT’s 1.5 m² listing at £39.99 shows no reviews in the capture. YeloDeer’s twelve-square-metre mat at £92.98 is the large-floor outlier. Reviews say the pack is the mat only. The listing prints 10.43 A and a 230 watt fragment that does not match. Use the amp line, about 2,400 W at 230 V, and let the electrician confirm. Skip it if you read kit as thermostat included, or if reports of smaller mats than ordered worry you.

Skip the 12 V film for a house floor

The 12 V heating film with M3 thermostat at £154.00 belongs with caravans, motorhomes and floating laminate on 12 V, not with a new 230 V circuit under bathroom tile. It shows 4.3 from 66 reviews, but many of those stories are vehicle installs. The listing’s watt lines conflict: 65 W, 130 W/m², and a size line that does not simplify to one number. Do not merge it into a house-mat shortlist because it appeared nearby in search. Keep vehicle products off a bathroom tile schedule.

Common questions

Which mat in this set includes a thermostat?
Two HEATIT kits name ET-81 or ET-84 in the title and box list. The 12 V film includes an M3 thermostat for 12 V use. Every other 230 V row here is mat-only or sensor-tube-only on the captured pages.
Is the cheap 5 m² 150 W/m² mat a good buy?
It is the only 150 W/m² option and the lowest price per square metre if you ignore the thermostat, but five reviews and a mat-only box list are thin evidence. One UK laminate review reported barely warm floors. Treat it as a conditional 150 W trial, not a default best.
Are the five-star listings with one review the best?
No. One rating without review text is not a sample. The bolisi mat and the five-square-metre ET-84 kit each show 5.0 from one review in the capture. A wider sample, such as 4.4 from 36 on the two-square-metre kit, is the stronger star line in this set.
What if I already own a thermostat?
Minimat HEATIT rows, bolisi with its sensor tube, and YeloDeer on a large floor are the mat-first options, provided your controller accepts a floor probe and matches the load. A sensor tube is not the controller.
Why is a mat with no thermostat still not the cheapest once I add a controller?
Shelf price ignores the controller. A £33 mat plus a separate probe thermostat can still beat a £99 kit, but only if you price both before ordering. This page does not invent a separate thermostat price.
Which listing is for a larger 230 V floor?
The twelve-square-metre YeloDeer mat is the largest roll in the capture. Use the 10.43 A line for load planning. Reviews say the controller is separate, and several describe smaller mats than the size ordered.
