Working in Milton Keynes
We work right across Milton Keynes — MK6, MK9, MK10 and 1 more postcode districts — and in neighbouring Leighton Buzzard and Ampthill.
In a city the size of Milton Keynes, parking and access for a skip are worth sorting before the start date — we will ask at the survey. Whether your Milton Keynes bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. If your Milton Keynes home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Supplies across most of Buckinghamshire 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
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- 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
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.
