Boiler repairs, no heating or hot water, radiators, cylinders and controls in Islington. We cover Islington and the wider Islington area. Tell us what has stopped working and we’ll arrange the right specialist.
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.
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.
Repeated pressure loss needs investigation; topping up does not explain why it keeps happening. Share the cold pressure reading, how quickly it drops and any visible leaks or fault code. Use only your appliance’s own user instructions for routine checks; do not remove the casing.
Choose repair when the boiler stops working or a fault keeps returning. Servicing is planned maintenance and does not automatically include fixing an existing breakdown. Tell us about both needs so they can be scoped together.
Choose the closest problem
Start with the symptom, or choose a planned service. See what we check, repair options and what to tell us.
Find the cause
We arrange an engineer to investigate the fault and explain the repair options. Your quote sets out labour, parts, VAT and any return visit.
A fault code or photo helps us prepare. Hidden leaks, replacement equipment and making good may need a separate investigation or quote.
The right professional
Gas boilers, electric heaters, unvented cylinders and communal plant need different expertise. Tell us what is installed so we can arrange the right specialist and access.
You can check a gas engineer’s registration and appliance work categories before the visit.
HSE guidance on checking an engineerAll 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 an Angel or Highbury flat with a leaking radiator, describe damage in your room and any report from the flat below. Tell us where system isolation can be accessed if known. Locating the leak and making good are separate parts of the scope.
For an Angel or Highbury flat, a leak or repair opening may affect another home as well as your own. Original surfaces and shared boundaries should be identified before work is specified.
If heating pressure falls and another room or flat shows water damage, include both reports and any radiator work history. The engineer needs to distinguish heating pipework from other water sources before repair and making good are planned.
For an older or decorative radiator, send its valve details and explain whether it leaks or heats unevenly. Matching appearance does not establish connection compatibility. Any pipe alterations, lifting of finishes or wall repairs need separate scoping.
Example work, explained
Need similar work at your Farringdon property? Tell us the symptoms and access arrangements.
Include access above or below, existing repair reports and photographs of finishes to retain. State who can approve work to shared or protected parts.
No. Repeated pressure loss needs investigation. Share the pressure pattern and earlier findings; do not keep using a repeated top-up as a substitute for locating the fault.
Often the enquiry can start as a valve repair, but the condition, connections and system need checking. We do not assume that a cold radiator requires full replacement.
Local service guides and related borough coverage. Named centres are drawn from the London Plan town-centre network, with council references for additional places. A centre, neighbourhood and postcode district can have different boundaries.
Use a borough, local area or the first part of a postcode. Choose a result for service details and a quote.
August 2026 ONS postcode data identifies boroughs sharing an outward district. Named centres use London Plan references; neighbourhood postcode examples use local address sources. Neither defines an exact neighbourhood boundary. Even a full postcode entered here is matched only by its first part.
Where a dedicated local service guide is available, we link to it. Other places lead to the relevant borough guide with your selected area carried into the enquiry. Your full repair address is needed when arranging attendance.
Islington: E8, EC1A, EC1M, EC1R, EC1V, EC1Y, EC2A, EC2M, EC2Y, EC4A, N1, N16, N19, N4, N5, N6, N7, N8, NW5, WC1X.
These are borough-wide postcode associations. A district can cross boroughs and include other neighbourhoods or addresses outside London. Even a full postcode shown in the finder gives district suggestions, not an address check. Give the street address and full postcode when booking.

How your repair quote worksExample problem & repair approach
The problem: One room remains cold while the rest of the home heats up.
How we can help: Check valve operation and how water circulates through the radiator, then recommend a valve repair, balancing or further investigation.
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.
Choose a repair if the appliance has stopped working or has a recurring fault. Choose servicing for planned maintenance. If you need both, tell us so we can plan and price them together.
Yes. Explain who reports the fault, who can arrange access and who approves expenditure. For communal heating or hot water, tell us who manages the building system before a private repair is arranged.
No. We’ll contact you with the next step, price and available appointment. Call for urgent repair availability; do not wait for an online reply in a safety emergency.
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.
