Working in Formby
As well as Formby itself (L37 and L38), we survey in Maghull, Southport and Bootle.
Formby gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check door thresholds in Formby homes at the survey, because underfloor heating and new tiles raise the floor slightly. Where a Formby home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
Supplies across most of Merseyside are soft. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- A floor sensor set between the heating runs and wired back to the thermostat
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
Decisions to make first
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
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.
