Working in Wrexham
As well as Wrexham itself (LL11, LL12 and LL13), we survey in Brymbo, Rhosllannerchrugog and Buckley.
In a city the size of Wrexham, parking and access for a skip are worth sorting before the start date — we will ask at the survey. Whether your Wrexham bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. Where a Wrexham home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
Most of Clwyd has moderately hard water. Mid-tone grout and matt tiles hide the odd water mark better than dark grout and high gloss. 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
- 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
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.
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
Rules that apply in Wales
In Wales, the Welsh Part P also makes a new underfloor heating circuit notifiable, and it covers more bathroom electrical work than the English version. A registered electrician handles the notification.
