Working in Cowley
We cover every part of Cowley, including OX1, OX3 and OX4, and nearby Oxford (2.5 miles) and Abingdon (5.3 miles).
Being a smaller town does not change how we work in Cowley: free survey, written quote, one team. If your Cowley home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. Whether your Cowley 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 Oxfordshire 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
- 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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- A floor sensor set between the heating runs and wired back to the thermostat
Decisions to make first
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.
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.
