Working in Daventry

We work right across Daventry — NN11 — and in neighbouring Rugby and Northampton.

Homes in and around Daventry vary, so we look at the floor, the walls and the water system before we price anything. If your Daventry bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. We check door thresholds in Daventry homes at the survey, because underfloor heating and new tiles raise the floor slightly.

Most of Northamptonshire has hard water. 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

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
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
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded

Decisions to make first

Floor finish

Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.

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.
