Working in Holyhead
We cover all of Holyhead, including LL65, and nearby Caernarfon and Bangor.
Being a smaller town does not change how we work in Holyhead: free survey, written quote, one team. For Holyhead homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. Whether your Holyhead bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Supplies across most of Gwynedd are soft. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- 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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
Decisions to make first
Electric or wet
Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.
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.
