Working in Southsea
We work right across Southsea — PO1, PO4 and PO5 — and in neighbouring Portsmouth and Gosport.
Southsea gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Southsea bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. Whether your Southsea bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Water across much of Hampshire 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- 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
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.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
