Product pages and prices

The £79.99, £89.99 and £219.99 figures are reference prices including VAT supplied for this campaign as at 22 July 2026. They are not offers or guaranteed prices. Current product version, included items, stock, delivery, installation, accessories and final terms must be confirmed separately.

Energy and expense statements

Room schedules, zoning, remote access and more representative temperature measurement may help avoid heating unused rooms or an empty home unnecessarily. No saving, percentage reduction, payback period or lower bill is promised. Outcomes vary with the home, insulation, heating system, installation, settings, weather, occupancy, behaviour and tariff.

Compatibility and installation

Compatibility depends on the exact boiler, heat pump, valves, wiring, network and other controls. Some products require Bridge X or another compatible Thread Border Router. A suitable professional should be used where the manufacturer’s instructions or the work itself require it.

Images and source material

Images are product references and may include elements of source screenshots used to identify the model. Layout, interface, accessories and packaging may differ. Review current manufacturer documents and the eventual supplier’s written offer before deciding.
