Across London · Homes, landlords & managed properties · Your area: Knightsbridge
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.
Tell Mayfair where the water is appearing and what has changed. We can help coordinate an assessment, compatible parts and the agreed repair, with any follow-on work priced separately.
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
You do not need to know the technical name. Choose the description that fits, then see the repair options and what to include in your enquiry.
Water continuing to flow into the bowl, a cistern that refills repeatedly or a flush button that fails are reasons to request a toilet repair. Tell us whether the cistern is concealed. If the bowl fills up instead of draining, choose toilet unblocking.
It may be repairable with a suitable washer, seal or cartridge. The fitting’s condition and availability of compatible parts determine whether repair or replacement makes sense. A photo of the tap and the leak helps us plan the visit.
Report where the water appears and whether it happens when the tap runs or the sink empties. Leaks from connections and water backing up through a blocked waste need different checks. Mayfair can arrange the appropriate investigation without asking you to dismantle anything.

What affects the quote
A more useful first enquiry
Describe whether the water appears at a fitting, beneath a sink or through a surface. Photos can help plan the assessment; hidden leaks may need investigation before a repair can be quoted.
Tell us about fitted panels, shared supplies and the person who can arrange access. Mayfair will confirm any need for opening-up and reinstatement before agreeing that work.
Share the make, model and finish of visible fittings. Approve a compatible replacement rather than assuming a similar-looking item will fit.
All of London covered
We cover all 32 London boroughs and the City of London. Call with your postcode for the next available visit, or send a quote request with the fault and access details. Arrival time depends on the job, available specialist and travel conditions.

The problem: Water appears in the cupboard when the sink is used.
How we can help: The plumber traces the leak, repairs the accessible waste fitting where suitable and checks for leaks with water running.
