Working in Bletchley
We cover every part of Bletchley, including MK1, MK2 and MK3, and nearby Milton Keynes (3.5 miles) and Leighton Buzzard (6.2 miles).
In Bletchley, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Bletchley bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. For Bletchley homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Water across much of Buckinghamshire is 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
- For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- 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.
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.
