A thermostat that will not turn on can leave you unsure whether the heating is safe to use or simply not responding. The visit focuses on the control, its power source and the relevant heating connections so you get a reasoned next step rather than a guessed part.
What the symptoms can tell us
A blank or inactive unit can have several explanations. A battery model may have exhausted cells or poor battery contact; a mains-powered or wired control may have a supply, connection or internal fault. The screen can also appear inactive after a setting change, lockout or a period without demand, so the display alone does not prove the thermostat has failed. In some systems the control has power but the heating circuit does not respond, which is a separate issue. Make a note of when it stopped working, whether it went blank suddenly, and whether the boiler or radiators still respond to another control. Those details help distinguish a local control problem from a wider heating fault.
Checks during the visit
We begin with the make and model, the way the thermostat is powered and any safe, accessible user settings. Where appropriate, the engineer checks batteries and contacts, confirms whether a supply reaches the control, inspects accessible connections with the circuit safely isolated, and assesses whether a call for heat is being sent. The heating response is considered alongside the thermostat rather than assumed to be caused by it. The visit may also establish whether a receiver or separate programmer is involved. If there is no clear fault at the thermostat, the findings can point toward a heating-side control or wiring issue that needs separate diagnosis. No live parts are handled by the customer.
Repair choices and limits
If depleted batteries or a straightforward accessible connection is responsible, the engineer can explain the correction and confirm whether the display returns. A failed thermostat may be repairable only if the model supports it and suitable parts are available; otherwise a compatible replacement may be the practical choice. If the control wakes but still cannot operate the heating, further work could involve a receiver, wiring or heating control and will be discussed as a defined next step. A new unit is not fitted merely because the screen is blank: the reason for the failure and the existing system compatibility should be understood first. Any work beyond the agreed visit is quoted for approval.
Electrical and heating safety
A thermostat is a control device, not permission to work inside a boiler. Maintenance Men handles thermostat controls and suitable electrical or water-side heating faults within scope, but does not carry out gas work or open a gas boiler to adjust gas components. If symptoms suggest a combustion, flue or other gas-side safety concern, stop using the appliance if advised, leave it unopened, and arrange a Gas Safe registered engineer; an urgent gas smell is not a routine booking. Do not remove covers, probe live terminals or bypass a control. The engineer will explain any limit before proceeding.
Booking, price and next steps
The booking is for the stated diagnostic or defined thermostat visit, not an automatic promise that every fault can be fixed in one appointment. Booking fee is paid when booking; the hourly labour rate depends on how soon you need the visit. The full cost for the agreed work is quoted and you approve it before work starts. Any required replacement control, wiring materials or other parts can be identified and quoted separately; parts are not assumed to be included. Availability, compatibility and access may affect the next step. Book online and include the thermostat make and model, heating system type if known, symptoms, and anything already checked.
After the visit
After a correction, check that the display remains on and the thermostat responds to ordinary controls, without opening the unit. Keep the model details and note any error symbols or repeat loss of power. If it goes blank again, record the timing and whether household power has also interrupted. Do not keep changing wiring or bypassing the thermostat to force the heating on. Share any recurring symptom when arranging further work; it can help determine whether a control, supply or wider heating diagnosis is appropriate.

What our customers say about our heating & radiators service
5 out of 5 from 10 reviews
Fast, tidy and friendly
Booked the £220 booking-fee slot on Tuesday and got a message confirming the time the same morning. The cause was explained, the price agreed before any work started, and the job was done in about 46 minutes. Clean and tidy when they left.
Job: No Heating from Boiler
Turned up when they said
What I appreciated was being told what was actually wrong before anyone started. Sorted in under 46 minutes and the invoice matched the quote to the penny.
Job: Expansion Vessel Fault
Exactly what was quoted
I had put off sorting this for months because I expected a runaround. Quoted the booking fee plus hourly rate upfront, stuck to it, and actually found the underlying cause rather than just clearing the symptom. Worked neatly and hoovered up afterwards.
Job: Airlock in Hot Water System

Questions people ask about thermostat not turning on
Straight answers to the things customers ask most often before booking.
Can I change the batteries myself?
If the thermostat is clearly battery-powered, use the battery type and polarity shown by its maker and avoid touching wiring. If it remains blank or you are unsure whether it is mains-powered, stop and arrange a check.
What will the engineer check?
The engineer identifies the model and power method, checks accessible settings and battery condition where relevant, then assesses the supply and control response within safe limits. The visit is diagnosis-first, so the result may indicate a separate heating fault.
Is it safe to remove the thermostat from the wall?
Do not remove a wired thermostat or touch terminals; some controls carry electrical power. The engineer will isolate and inspect accessible wiring as appropriate, and will stop if work falls outside safe electrical scope.
Does a blank display always mean I need a new thermostat?
No. Batteries, power supply, contacts, settings or a separate control fault can produce similar symptoms. Replacement is considered after checks and compatibility review.
How is the price worked out?
The booking fee is paid when booking, and the hourly labour rate depends on how soon you need the visit. The full cost is quoted for your approval before work starts; parts or materials can be identified and quoted separately.
