Working in Hedge End
We cover every part of Hedge End, including SO30, and nearby Eastleigh (4.3 miles) and Southampton (4.5 miles).
Hedge End gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Hedge End bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. If your Hedge End home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- 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
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
