Working in Finchley
We work right across Finchley — N2, N3 and N12 — and in neighbouring Muswell Hill and Cricklewood.
London homes in Finchley often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Where a Finchley home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Finchley home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Supplies across most of Greater London are very hard. Hard water leaves white marks on dark grout and gloss tiles, so matt finishes and stain-resistant grout are the practical choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A floor sensor set between the heating runs and wired back to the thermostat
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- Bringing the system up to temperature gradually once the adhesive and grout have cured
Decisions to make first
Electric or wet
Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.
Floor heating and towel rail
Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.
Rules that apply in England
In England, a new circuit for underfloor heating is notifiable under Part P, and so is connecting it to an existing circuit in a room with a bath or shower. The electrician either self-certifies through a competent person scheme or the work is notified to building control.
