Diagnosis before replacement
- Room thermostats and wireless receivers.
- Programmers, timers and heating schedules.
- Thermostatic radiator valves and manual valves.
- Control communication and accessible wiring checks.
- Boiler and control compatibility assessment.
- Testing and a clear operating explanation.
A new thermostat or smart control is not always the answer. Prime will first establish whether the issue comes from the thermostat, receiver, heating programmer, boiler, valve or wider heating system.

Frequently asked questions
Before you book
Why is my thermostat not turning the heating on?
Possible causes include settings, batteries, communication, wiring, a receiver, zone controls or another heating-system fault. The controls and system should be assessed together.
Can an older thermostat be replaced with a smart thermostat?
Often, but compatibility depends on the boiler, wiring, existing controls, heating zones and the chosen product. A survey confirms the appropriate options.
Can you help with radiator valves?
Yes. Prime can assess thermostatic radiator valves and manual valves as part of radiator and heating-control work.
Will you show me how the new controls work?
Yes. The controls will be tested and their everyday operation explained before the job is complete.
Do new controls always reduce energy use?
Better control can help avoid unnecessary heating, but savings depend on the property, system, settings and how the heating is used.
