Can underfloor heating be installed in hot weather?

Author: Co-Dunkall Ltd || Date: 2nd July 2026

The temperatures over the past few weeks have soared, but we’re still hard at work installing underfloor heating systems across Norfolk and beyond.

One question we’re often asked is:

“Can underfloor heating be installed in hot weather?”

The answer is yes. Underfloor heating can be installed all year round, whatever the weather. While we recommend using antifreeze during installations in the colder months, summer conditions present no issues for installation work.

In fact, now is often the ideal time to plan your underfloor heating project. Getting the system installed during the summer means your build or renovation stays on schedule and you’ll be ready for those colder months before they arrive.

Whether it’s a new build, extension, commercial project or home renovation, our team is on site whatever the weather, delivering high-quality underfloor heating installations and screed solutions.

It might be the last thing you’re thinking about during a heatwave, but your future winter self will thank you for it!

If you’re planning a project and would like advice on underfloor heating, get in touch.

Helpful advice, efficient measures, laying out was done with attention to detail. Pouring was prompt and careful. The skip liner was much appreciated. The levels were perfect for our doors. Helpful advice and ensured we’re satisfied with the results. Thank you and well done. 👍🏻

 Trustindex verifies that the original source of the review is Google. I did screed with them twice, we had our house done in 2 phases and in the 1st phase they supplied us with specific stats, on the 2nd phase they supplied us with different stats model and a control box which allows to connect to them remotely but, then I had an issue with the phase 1 stats won't connect to the system as they don't support that functionality. I rang their customer support and explained the issue, they offered to swap the phase 1 stats with new ones so, all stats will be from the same model and all will connect to the control box.
One more word about their expertise, the 2 phases were done a part so the 1st phase screed was higher than the existing old bit, when they came to do the old bit on the 2nd phase, I asked if they can do the screed so that both bits will be same height, they did it perfectly, both phases met up level and the wood floor on top is at the same height, I must say I was sceptic but, these guys are awesome, they are experts in what they do. that made me so happy!
That is a company who cares about their business and about their customers.
I will definitely recommend and will definitely do business with them again.
Thanks you Co-Dunkell

 Trustindex verifies that the original source of the review is Google. We had our screed pumped in and laid by the team at Co-Dunkall today at our self-build, the three man team onsite and those in the office were all professional and friendly at all stages from quotation, survey and the final delivery and instation. Everyone has done what they said they would do and within the timescale given. If you need pumped floor screed I can recomend this company 100%

 Trustindex verifies that the original source of the review is Google. We had Co-dunkall provide a cemfloor screed for an outbuilding which needed the floor raising. Thoroughly professional service 3 survey calls and inspections prior to the job. Nikki and the office team all highly knowledgable on so many aspects and on the day they even provided a 6 wheel mini mix to accommodate the property complexities. Good follow up and so pleased for a  very clean and tidy washout considering how messy the job can be. You would not know they had been on site. End result is exactly what we needed
