For safely accessible, straightforward faults. Parts, materials and further work quoted separately. If a fix needs more work, the agreed visit charge covers call-out and assessment.
Call for your visit price and arrival estimate. Sending a form does not book a visit.
A blank thermostat, unreliable schedule or lost connection can prevent the heating from doing what you expect. Tell Mayfair the control model, what the display shows and whether you need fault finding or a planned replacement.
Your visit, explained
Call-out, assessment and labour to fix a small, straightforward issue on the first visit.
For safely accessible faults that can be resolved on the first visit. Parts, materials and further work are quoted separately for your approval.

Check availability: 020 4571 4235If a first-visit fix isn’t possible, the agreed visit charge still covers the call-out and assessment. We explain the fault and quote any parts, further investigation or larger repair for your approval.
We’ll give you the full visit price when you book. There is no additional call-out fee on top of that price.
Any workmanship guarantee is set out in your written quotation: the work covered, duration, exclusions and how to report a problem. Product warranties follow the manufacturer’s terms. A repair does not automatically guarantee the whole existing system. Your statutory consumer rights are unaffected.
Gas work must be carried out by an appropriately qualified Gas Safe registered engineer. Electrical and unvented hot-water work need the relevant competence and certification where required. Mayfair matches the work to the appropriate specialist.

The situation matters more than the name of the fault. Use the safety guidance above if anyone may be at risk.
Understand the repair
Controls must suit the boiler and the way heating and hot water are divided into zones. An app connection problem, a room thermostat fault and a wired control fault need different checks. A smart thermostat should be selected for compatibility, not appearance alone.
A useful first enquiry
Check only normal user settings or user-replaceable batteries in accordance with the manual. Do not bridge terminals, bypass controls or remove wired covers. If failed controls leave the home without heat, call to discuss urgent availability.
The existing wiring, control protocol, receiver, zones and desired features affect the scope. Product supply, fitting and setup should be identified. Wi-Fi changes or wider electrical and heating faults may need separate work.
Send the symptoms, equipment details and postcode. We’ll arrange the right engineer to investigate the fault and explain the repair options.

How quotes and orders work →Example problem & repair approach
The problem: The thermostat calls for heat but the system does not respond.
How we can help: Check the controls and system response, fit a compatible replacement where needed and demonstrate the agreed heating schedule.
No. The boiler, control connections, hot-water arrangement and number of zones need checking. Send the current models and the proposed product link before buying a replacement.
The displayed request and the system’s response can differ. Explain whether all radiators are cold and whether the boiler shows a fault; assessment may involve more than the thermostat.
Ask for setup and a user demonstration in the brief. Agree the rooms or zones, normal schedule and any app requirements before the installation is confirmed.
