Frequently asked
Your questions, answered
Can underfloor heating be added to an existing floor, or does it need a new build?

Yes — every engineer working on underfloor heating in South West London is Gas Safe registered, manufacturer-trained and fully insured to £5m public liability. We'll show our ID on arrival.

Yes. We provide a free, no-obligation written quote with fixed pricing, so you know exactly what your underfloor heating will cost before any work starts.
