Plumbing repairs for homes, landlords and managed properties in Knightsbridge. Tell Mayfair about the leak, tap, toilet or shower fault and your full postcode. We arrange a plumber to find the cause, explain the repair and fit suitable parts where needed.
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.
Planning work in Knightsbridge
For a Knightsbridge concealed shower or toilet fault, send the visible control plate and any known manufacturer details. Include the building contact if water isolation is outside your own property.
Tell us whether the property is a house or flat, which fittings are affected and who can authorise the work. Share pictures of the fault and visible product labels to help us prepare for the visit. Do not remove covers or panels just to make an enquiry.
These are areas for service enquiries, not separate Mayfair offices. Call with your postcode to check availability.
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.
For a Knightsbridge property with estate or concierge arrangements, book the contractor entrance and agree protection for retained finishes. Hidden fittings, bespoke joinery and shared equipment need separate access information.
For a managed flat, identify whether water is escaping from a tap, cistern or pipe inside the home, or from a shared riser. We can plan the private repair; building-managed isolation and access need the responsible contact.
Show the fitting, its brand and any existing service opening. A concealed mixer or cistern may be repairable through its designed access; cutting tiles or cabinetry is a separate decision. Parts compatibility matters as much as the matching finish.
Example work, explained
Need similar work at your Knightsbridge property? Tell us the symptoms and access arrangements.
Include the service entrance, unloading arrangements, working hours and fitting specifications. Tell us who can approve access behind panels and work beyond the original brief.
Tell us who can open the cupboard and approve any interruption to other homes. We will plan access with that contact. Do not force entry or operate unfamiliar shared valves.
We first consider the access designed into the installation and the component needed. If opening-up is necessary, the extent and making good need a separate agreed scope.
Knightsbridge reaches Westminster and Kensington and Chelsea. SW1X and SW7 are useful examples, not an exclusive boundary. Use the address to identify the appropriate council and building-management route.

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.
Find the right repair
Choose the closest problem to see what can be checked, what affects the cost and what to include in your enquiry.
We use your fault description and photos to prepare the visit. The plumber checks the cause and explains the repair; your quote sets out labour, parts, VAT and any return visit. Concealed faults may need further investigation.
Tell us if you also need water-damaged plaster, cabinetry or decoration made good. The plumbing repair and follow-on work can be planned together, with each stage included explicitly in the written scope.
From £85 including VAT for call-out, assessment and labour to fix a small, safely accessible fault on the first visit where possible. We’ll give you the full visit price when you book. Parts and further work need a separate quote and your approval. If the repair needs more work, the visit charge still covers call-out and assessment.
Send your full postcode and the plumbing problem. We use them to check the appropriate trade and current availability. Postal districts cross borough boundaries, so an area match alone does not confirm attendance.
Yes. Include the reported fault, who can arrange access and who approves the work. Where a tenant, landlord or managing agent needs to authorise attendance or expenditure, agree that before booking.
Call to discuss current availability. This website does not promise same-day attendance, a fixed response time or 24-hour cover. Do not wait for an online reply if there is an immediate risk.
Share the brand, model and finish if known. Mayfair can discuss sourcing compatible parts or a suitable replacement, with cost and any return visit agreed before ordering.
Only if it is included in the written scope. Tell us if you also want plastering, cabinetry repairs or decorating so the complete job can be planned and quoted.
If the job involves more than one trade, include the complete list in your enquiry so the work can be planned together.
