Working in Louth
We work right across Louth — LN11 — and in neighbouring Cleethorpes and Grimsby.
Louth gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Whether your Louth 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 Louth bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.
Most of Lincolnshire 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- 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
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.
