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.
If your home has no heating, tell Mayfair whether hot water still works and whether every radiator is affected. Those details help separate a whole-system problem from an individual radiator or room-control fault.
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.
For urgent London plumbing and heating repairs, we aim to arrive within 1 hour, subject to availability, postcode, the specialist required and travel conditions. Call for your estimated arrival time.
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
An assessment may involve the boiler, programmer, room thermostat, circulating system or zone controls. Heating that stays off at every radiator needs a different investigation from one room that is slow to warm. Parts should follow the findings, not an assumed diagnosis.
A useful first enquiry
If it is safe and there is no gas smell, alarm, burning or water near electrics, you can read the display and check the normal heating schedule against the user manual. Leave internal gas, wiring, pump and valve work to the appropriate engineer.
The quote depends on whether the fault is in a control, the appliance or the distribution system, and whether access to shared equipment is needed. Explain any previous repair so the assessment does not assume a new, unrelated fault.
Send the symptoms, equipment details and postcode. We’ll arrange the right engineer to investigate the fault and explain the repair options.

The problem: The radiators stay cold when heating is requested.
How we can help: Check the heat source, controls and circulation to locate the fault, then carry out the agreed repair and test the heating response.
This pattern can involve heating settings, controls or circulation. It does not identify a single failed part. Tell the engineer which functions still work and when the heating last operated normally.
Contact the building manager or communal-system operator as well as reporting the problem. A shared supply may need their investigation and authority; work inside your flat may not resolve the building-wide fault.
Use the cold radiator repair page and name the affected room. If the rest of the home has heat, the assessment can focus on that radiator and its controls before considering a whole-system repair.
Choose the closest problem
Start with the symptom, or choose a planned service. See what we check, repair options and what to tell us.
For leaking taps, toilets, showers and water-supply faults, use the plumbing pages. For a boiler, radiators or stored hot water, explore the heating options.
If the job involves more than one trade, include the complete list in your enquiry so the work can be planned together.
