Fitting underfloor heating in a Victorian terraced house

Interior stylist and blogger Maxine Brady shares the latest stage of her home renovation project – installing underfloor heating

TODO alt text

Since I move into my little two-up-two-down terraced house in Brighton, I have been putting in a new boiler and renovating both the central heating system  and sash window.

Now, it’s time for the fun stuff – my new kitchen. It’s been overhauled from top-to-bottom, which I will share soon. But I thought I would start with the basics first – the underfloor heating system. It took me while to decide whether to go for underfloor heating as it felt like a luxury when I was facing the cost of doing up the kitchen from scratch. Now it’s in, I’m so glad I went for it.

The Cost

To give you a guide of costs for the underfloor heating, here’s how much it cost me. As a guide, our full kitchen area is 6.6332 sqm, but you have to minus the area where the kitchen units are going, so the area we needed to heat works out as 3.9485 sqm. For that size room, we needed the following:

4iE Smart WiFi Thermostat in Bright Porcelain = £199.99 

DWS600 Undertile Heater = £222.99 

10mm Insulation Board Singles =  £245.80 

Insulation Board Fibreglass Tape 90m = £4.49

Total = £673.27 


Before: The tiled floor was so horrible – 1980s terracotta tiles, which were freezing. We always had to wear slippers as it was so cold


The kitchen is at the back of the house and has a concrete floor, so there was no way we could put in piping for a radiator.  This is when I started researching underfloor heating and shopped around for the best one for my budget, which came from Warmup

The team at WarmUp suggested we went for under-tile electric heating with a Wi-Fi thermostat.  We just gave them our room measurements and our kitchen plans and then they worked out how much we needed. Our builder then put down the Warmup insulation boards all over the floor.


The heating cable is the thinnest available – only 1.8mm. The small cross-section of the heating element allows it to be installed without the need for a layer of self-levelling screed.  It’s pretty easy to put down and, as it is a flexible strip, it’s perfect for irregular rooms or spaces with a lot of fixtures or corners, like ours

The trickiest bit was deciding where to put the thermostat. Eventually, we went for just outside the room. I’ve been tinkering with the best setting and have gone for the ‘holiday’ mode. It comes on for a few hours in the morning and then for a couple of hours in the afternoon. With the smart thermostat – which runs off our Wi-Fi – and because the kitchen is warmer, I don’t crack the heating on so much in the rest of the house, so our bills have stayed the same.

By going for underfloor heating, I’ve saved space by not having a radiator on the wall. Funnily enough, the underfloor heating is the first thing friends notice as they come in the kitchen. It feels so luxurious.

The Verdict

I think underfloor heating is one of the smartest ideas I’ve had for my home so far. I will save money on heating bills, plus it will add value to the house in the long run, as it’s considered desirable to potential buyers.  It was also way cheaper than digging up the floor to put a radiator, saving us space in our tiny kitchen. And the dog loves it!
