Lewisham Underfloor Heating Costs
Underfloor heating prices in Lewisham are mostly set by the floor area, wet or electric, the existing floor and whether screed and finishes are part of the job. Typical prices:
| Project | Typical price in Lewisham (inc. VAT) |
|---|---|
| Electric underfloor heating in a bathroom | £1,000 – £2,000 |
| Wet system in a 20–40m² extension | £2,500 – £4,500 |
| Wet system across a ground floor | £4,500 – £7,500+ |
Electric systems cost less to install but more to run, which is why most installers recommend a wet system for extensions and larger rooms.
Building Regulations and Underfloor Heating in Lewisham
You won't need planning permission for underfloor heating in an existing room. An extension will need building regulations approval, including the floor insulation beneath the heating, and electric systems on a new circuit should be fitted by a registered electrician.

Common questions from homeowners
How much does underfloor heating cost in Lewisham?
Underfloor heating in Lewisham typically costs between £1,000 and £7,500. A single bathroom with an electric mat is the cheapest type of job, and a fully screeded wet system under an entire ground floor is the most expensive.
How long does underfloor heating take to install?
An electric mat in a bathroom can be laid in a day. A wet system in an extension takes one to five days to install, but screed then needs several weeks to dry before floor finishes go down.
Does underfloor heating raise the floor level?
Low-profile systems and electric mats add only a few millimetres to a couple of centimetres. Screeded systems need more depth, which is easiest to allow for in a new extension.
Can I have underfloor heating and radiators together?
Yes. Many homes run underfloor heating downstairs and radiators upstairs from the same boiler, with a mixing valve keeping the underfloor circuit at a lower temperature.
