Underfloor Heating in London

Wet and electric underfloor heating, zoned controls, screeding and commissioning.

What we do

Underfloor heating frees up every wall in the room and runs at a lower flow temperature, which suits a heat pump if you ever fit one. The decision to make early is wet or electric — wet for whole floors and new screed, electric for single rooms over an existing slab.

Included as standard

  • Wet (hydronic) system design and installation
  • Electric matting for bathrooms and single rooms
  • Manifolds, zoning and thermostatic controls
  • Insulation boards and liquid or sand-cement screed
  • Integration with existing boiler or heat pump
  • Pressure testing, commissioning and handover
Typical timescale
3–7 days plus screed cure

Design, testing and commissioning

A wet system is designed around heat loss per room, pipe spacing and flow temperature. The insulation beneath the pipework is what makes it work: without it, a meaningful share of the heat goes into the slab and the ground rather than into the room.

Pipework is pressure-tested and left under pressure while the screed is poured, so any damage during the pour shows immediately rather than after the floor finish is down.

Screed then has to cure before heat is applied, and the system is commissioned by raising the temperature gradually to a schedule. Rushing that cracks the screed.

Controls are zoned per room, and the installation is certificated as part of the electrical and heating work. Because the system runs at a lower flow temperature than radiators, it is also the decision that makes a heat pump viable later.

The limits above are the national permitted-development rules for England. Your borough may restrict them further through a conservation area or an Article 4 direction — we confirm the position for your address in writing before quoting.

Answers

Underfloor Heating — common questions

Do I need planning permission for underfloor heating in London?

It depends on the property type and what is proposed. Many single-storey rear extensions and loft conversions fall under permitted development, but those rights do not apply to flats and are restricted in conservation areas or where an Article 4 direction applies. We check the planning position for your specific address before quoting, and tell you in writing which route applies.

How do you price the work?

From a site survey, written up as a fixed and itemised scope before any deposit is discussed. If something genuinely unforeseen appears once work is opened up, it is priced and agreed in writing before we continue — never added to the final invoice after the fact.

When do I pay?

In arrears of work completed. You pay for work that has been done and inspected, not for work that has been promised. This has been how the company operates since 2008.

Do you handle Party Wall notices?

Yes, where the work requires them. Under the Party Wall etc. Act 1996, notifiable work on a shared wall needs 2 months written notice to the adjoining owner, while excavation near a neighbouring structure and building at the line of junction need 1 month. We serve the notices and manage the award process as part of the job.

Will I get certificates at the end?

Yes. Electrical work is tested and certificated under Part P, and building control issues a completion certificate where an application was required. You receive the handover pack — it is what a buyer's solicitor will ask for when you eventually sell.

How long will it take?

It depends entirely on scope, and we give a programme with the written quote rather than a guess on the phone. What we will not do is start a job we cannot resource, which is the usual reason a build stalls halfway through.
