Working in Cheltenham
We work right across Cheltenham — GL50, GL51 and GL53 — and in neighbouring Tewkesbury and Gloucester.
Across a large town like Cheltenham, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. We check door thresholds in Cheltenham homes at the survey, because underfloor heating and new tiles raise the floor slightly. If your Cheltenham bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.
Supplies across most of Gloucestershire are 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- 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
Decisions to make first
Mat or loose cable
Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
