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.
No hot water can involve a combi boiler, a cylinder, an immersion heater or a shared building system. Tell Mayfair what supplies your hot water if known, whether heating still works and whether one outlet or all taps are affected.
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.
Start with what you can see
That symptom needs a hot-water fault investigation, even if the radiators still work. Tell us whether you have a combi boiler, a cylinder or a communal supply, and whether every tap is affected. If only the shower has the fault, mention that before booking.
Understand the repair
The investigation follows the actual hot-water arrangement. One cold shower with working hot taps points to a different scope from losing hot water throughout the property. The assessment can include the heat source, normal controls and supply to the affected outlets.
A useful first enquiry
Read only normal user displays and settings. Do not remove immersion-heater covers, adjust safety valves or handle wiring. Unexpectedly scalding water, steam or a serious leak needs urgent specialist advice; keep people away from the affected equipment.
Boiler diagnosis, cylinder work, electrical testing and a shower-mixer repair require different skills and parts. Mayfair will clarify which assessment is appropriate and its charge. Replacement equipment is quoted separately if a repair is unsuitable.
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: Hot water is unavailable across the property.
How we can help: Identify the hot-water system and check its heat source and controls. Repair options depend on whether the fault involves a boiler, cylinder or electrical component.
Depending on the system, the fault may relate to hot-water demand, controls or stored-water heating. Report the pattern and system type rather than buying a valve or thermostat before the fault is assessed.
Mention that the other hot taps work. The shower fitting or its own water-heating arrangement may need attention, so the job may be a shower repair rather than a boiler repair.
Include its make or a picture of the accessible label. Mayfair will confirm the appropriate hot-water and electrical expertise for the reported fault before attendance is agreed.

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.
