Smart thermostat installation in Swansea
An engineer checks your boiler and wiring, fits the thermostat and sets it up with you. We pass your request to engineers covering Swansea.
Smart controls suit almost every Swansea heating system, including oil and LPG boilers on Gower as well as the gas combis that heat most of the city. The savings come from heating rooms only when they're used, and from the boiler running more gently.
Swansea at a glance
- How homes are heated
- 80.3% of Swansea households heat with mains gas only and 5.6% with electricity only. 1,959 homes (1.9%) rely on oil alone and 1,066 (1.0%) on tank or bottled gas. Source

- Median energy score
- About 53% of homes with an EPC in Swansea are rated band D or below (median score 68, band D), against 53% across Wales. Based on certificates lodged in the 10 years to March 2025. Source
Which thermostat for which system
A combi needs a single-channel smart thermostat for heating only. A regular or system boiler with a hot water cylinder needs a dual-channel model that also schedules hot water.
Oil and LPG boilers can usually be controlled by standard smart thermostats, since the thermostat only switches the boiler on and off. The installer should check the wiring centre first.
Simple to use
More than a third of Swansea homeowners own outright, and many are older. If you don't want an app, choose a model with a clear wall unit and physical buttons, and ask the engineer to set the schedule before they leave. Family members can then help remotely if needed.
Cold back rooms
Smart radiator valves let you warm a cold back bedroom or extension on its own schedule. In larger semis and detached homes, zoning like this saves more than the thermostat alone.
Setting it up properly
Ask the engineer to lower the flow temperature on your boiler while they're there. Modern condensing boilers are most efficient when the water returning from the radiators is cool, and a smart thermostat can keep rooms comfortable with gentler heating.
If your thermostat offers weather compensation or OpenTherm control, ask whether your boiler supports it. Both let the boiler adjust its output rather than just switching on and off.
Swansea homes and what they need
Hillside Victorian and Edwardian terraces
Thermostats in a cold hallway at the front of the house often over-heat the rest of the home. A wireless thermostat in the living room gives better control.
Interwar and post-war semis
If you have a separate timer and cylinder thermostat, a dual-channel smart controller replaces the timer and gives app control of hot water.
Waterfront and city-centre flats
Flats with electric heating need smart controls built for that system. Standard boiler thermostats won't work with storage or panel heaters.
Areas covered
Engineers who cover Swansea work across areas including Sketty, Uplands, Mumbles, Killay, Morriston, Townhill, Brynmill, Gorseinon, Pontarddulais and Clydach.
Questions people in Swansea ask
Can I fit a smart thermostat in a rented Swansea home?
Ask your landlord first. If they agree, keep the old thermostat so it can be refitted when you leave.
Will a smart thermostat cut my bills?
It can, if you use the schedule and away modes. The biggest savings come from not heating an empty house and from lowering the boiler's flow temperature.
