Working in Musselburgh
We work right across Musselburgh — EH21 — and in neighbouring Bonnyrigg and Colinton.
Being a smaller town does not change how we work in Musselburgh: free survey, written quote, one team. We check door thresholds in Musselburgh homes at the survey, because underfloor heating and new tiles raise the floor slightly. Where a Musselburgh home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
Supplies across most of the Lothians 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
- 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
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.
Insulation board thickness
Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.
Rules that apply in Scotland
Scotland has no Part P. Underfloor heating added during a straight bathroom refit rarely needs a building warrant on its own, but it must be installed, tested and certified to BS 7671 with RCD protection.
