Local Boiler Repair Help
Boiler Repair & Fault Diagnosis Across Croydon
When a boiler stops working properly, most homeowners want a local engineer who can diagnose the fault clearly and explain whether it needs a repair, routine maintenance or urgent attention. If you have searched for a boiler engineer near me, tell MPS what symptoms you are seeing and whether the boiler is showing a fault code, so we can discuss the next step.
MPS Heating & Plumbing LTD works across Croydon and surrounding areas. If the issue is not inside the boiler itself but involves leaking pipework, radiators or valves, we can check the wider heating system as part of the diagnosis.
Looking for boiler repairs near me in South London? We cover boiler repair appointments across Croydon, including South Croydon, Thornton Heath, Addiscombe, Selhurst, Norbury, East Croydon and West Croydon, as well as nearby areas. Call us with your postcode to check availability.
If the boiler is playing up, it is important to know the difference between servicing and repair. A service is for checking a working boiler. A repair is for diagnosing and fixing a fault. If your boiler is not working properly, the first step is usually a boiler repair or fault check.
Why MPS
Why Choose MPS For Boiler Repairs In Croydon?
A boiler repair should start with understanding the fault, not replacing parts by guesswork. Customers regularly mention that we explain what is happening, talk through the options clearly and keep them updated before and during the work.
Our boiler and heating reviews also mention prompt attendance, practical fault finding, tidy work and reliable follow-up. Customers have described short-notice boiler diagnosis, quick turnaround to identify and fix faults and ongoing help with boiler and heating problems.
MPS Heating & Plumbing LTD is Gas Safe Registered — ID 662170. Tell us what the boiler is doing, when the fault started and whether anything changed beforehand. We can then advise whether it needs a standard fault check or more urgent emergency boiler repair attention.
Fault Finding
Boiler Faults Need Proper Diagnosis, Not Guesswork
A boiler repair should start with finding the cause, not just swapping parts until the problem disappears. A pressure fault could be a leak, a weak seal, an expansion vessel issue, a pressure relief valve fault or something hidden inside the heating system.
If your boiler pressure is moving in the wrong direction, the symptoms matter. A boiler losing pressure can point towards leaks, seals or expansion-vessel problems, while boiler pressure that is too high can indicate a different fault within the appliance or heating system.
No hot water might point towards a diverter valve, thermistor, plate heat exchanger, controls issue, ignition fault or gas-side problem. If your radiators still heat up normally, our No Hot Water But Heating Works guide explains the most common causes. On older systems, a pilot light that keeps going out can also be a sign that the boiler needs proper fault diagnosis.
Strange noises can come from trapped air, sludge, pump strain, poor circulation, overheating or a heat exchanger problem. If the problem is specifically a noisy appliance, see our guide to boiler banging noises.
A diagnostic check may involve looking at the boiler pressure, controls, pump, motorised valve, magnetic filter, condensate trap, fan assembly, ignition electrode, gas valve, printed circuit board, pipework and system condition. The exact checks depend on the symptoms and the type of boiler fitted.
If the fault looks maintenance-related, we may also recommend a proper boiler servicing check for Croydon homes once the boiler is working safely again.
Common Boiler Problems
Common Boiler Repairs We Deal With
| Boiler Problem | What It Could Mean |
|---|---|
| No heating | Could be controls, pump, thermostat, air in the system, sludge, motorised valve issues or a boiler fault. In some homes, the issue starts with a thermostat not communicating properly. |
| No hot water | Often linked to diverter valves, sensors, thermistors, plate heat exchangers, ignition faults, low pressure or internal boiler faults. |
| Pressure keeps dropping | May be a leak, expansion vessel issue, pressure relief valve problem, seals or pipework fault. See our guides on boilers losing pressure, pressure dropping overnight and boiler leaks. |
| Boiler pressure too high | High boiler pressure may be connected to overfilling, expansion-vessel problems, filling-loop issues or another fault that needs diagnosis. |
| Boiler making noises | Can be air, sludge, poor circulation, pump strain, overheating or internal build-up. See our boiler banging noises guide for more detail. |
| Boiler keeps switching off | Can be caused by overheating, low pressure, blocked condensate, poor circulation, faulty sensors, ignition problems or electrical faults. Read more about why a boiler keeps switching off. |
| Boiler not turning on | May be linked to power, controls, pressure, thermostat settings, PCB faults, frozen condensate, ignition failure or safety lockout. See our guide on a boiler not turning on. |
| Fault codes showing | Fault codes help narrow the issue, but they do not always tell the full story. See our boiler fault codes page. |
Boiler Breakdown Support
When A Boiler Breaks Down At The Worst Time
Boiler breakdowns often happen when the system is under the most strain. The first cold week of winter. Heating running longer than usual. Taps suddenly running cold in the morning. The boiler reset button works once, then the fault code comes back again.
In some homes, repeated resets eventually turn into a boiler reset button not working situation once the underlying fault worsens. If the boiler has completely stopped working, contact MPS to arrange a boiler fault diagnosis.
Customer feedback gives a clearer picture of the work we are called for: faulty boilers diagnosed at short notice, tricky boiler problems resolved, quick turnaround to identify and fix faults, and repeat customers using MPS for ongoing boiler and heating issues.
We carry out boiler repair work across South Croydon, Selhurst, Addiscombe, East Croydon and West Croydon.
Main Repair Symptoms
What Has Gone Wrong With Your Boiler?
No Heating
If the radiators are cold, the issue may be inside the boiler, the controls, the pump, the valves or the wider heating system. See common causes of hot water with no heating.
No Hot Water
Hot-water faults can be linked to sensors, diverter valves, plate heat exchangers, ignition or pressure. Some homeowners still get heating normally but notice hot water taking too long before the boiler fault becomes more obvious.
Leaks And Pressure Loss
A boiler that keeps dropping pressure needs checking properly. Topping it up again and again is not a fix.
Inside Domestic Heating Systems
Boilers, Pipework And Heating Components
When a heating system develops a fault, the source is not always obvious from the boiler display. We consider the symptoms, controls, water pressure and associated pipework before recommending work. These photos illustrate different boiler and hot-water system layouts; they are not presented as photographs of the customer repairs described below.

Honest Repair Advice
Repair Or Replace? We’ll Tell You Honestly
One of the most common questions we hear is whether a boiler is worth repairing or whether it is time to replace it. There is no single answer because every boiler is different. The age of the appliance, its service history, the availability of parts and the type of fault all play a part.
If the problem is a failed diverter valve, faulty thermistor, ignition electrode, expansion vessel or another replaceable component, a boiler repair is often the most sensible and cost-effective option. Many boilers can continue running reliably for years after a quality repair, especially if they have been serviced regularly.
However, if the boiler has suffered repeated breakdowns, replacement parts are becoming difficult to source or the repair cost starts approaching the value of the appliance itself, it may make better financial sense to replace it. This is especially true where older boilers are becoming less efficient and more expensive to run.
If you’ve been searching for boiler repair near me, you’re probably trying to work out whether the boiler can be repaired properly or whether replacement is becoming the better option. We start with the fault itself, diagnose what has failed and explain the options before any further work goes ahead.
If replacement becomes the better long-term option, we can help you compare the repair against a boiler replacement in Croydon. You can also see our main boiler installation service in Croydon if a new boiler is eventually required.

Common Breakdown Causes
Why Do Boilers Suddenly Stop Working?
Boilers rarely fail for no reason. Most breakdowns happen because smaller problems have slowly developed over time. A system that loses pressure every few weeks, radiators that take longer to warm up or unusual noises from the boiler can all be early warning signs.
During winter the heating works harder than at any other time of year. Components such as pumps, expansion vessels, fans and ignition systems are under greater demand, while sludge inside the heating circuit can reduce circulation and increase strain on the boiler.
Other common causes include frozen condensate pipes during cold weather, faulty thermostats, blocked magnetic filters, electrical faults and boilers that have gone too long without a proper annual service.
If your boiler fault needs urgent or same-day attention, see our emergency boiler repair service in Croydon. For standard boiler faults and repairs, MPS provides boiler repair appointments across Croydon and surrounding areas.

Real Customer Experience
A Boiler Noise That Turned Out To Be A Kitchen Tap
A customer contacted MPS about a disturbing noise they believed was coming from their boiler. According to their Google review, another engineer had said the boiler needed hundreds of pounds of repair work.
- Reported problem
- A loud, persistent noise apparently coming from the boiler.
- Response
- The customer reported that MPS attended within two hours.
- Diagnosis
- After testing the source of the noise, MPS found that the problem was the kitchen tap rather than the boiler.
- Outcome
- The customer reported avoiding unnecessary boiler repairs and praised the honest explanation.

This is a customer-reported diagnosis, not a claimed boiler repair. The public review does not identify the precise test performed or confirm any work to the tap.
Clear Repair Advice
Boiler Repair Costs Depend On The Fault
A faulty sensor is very different from a leaking heat exchanger, and a simple pressure issue is very different from an internal boiler fault. We do not recommend replacing parts until the boiler has been properly diagnosed.
One of the main concerns with a boiler repair is cost. That’s why we explain the fault before carrying out any additional work. If the repair is straightforward, we’ll tell you. If specialist parts are needed, we’ll explain what is required and why.
Boiler fault diagnosis starts from £90 during weekday daytime hours. We explain the fault and any additional repair costs before carrying out further work. See our full pricing page for current guide rates.

Common Questions
Boiler Repair FAQs
How quickly can you attend a boiler repair in Croydon?
Response times depend on demand and engineer availability. Call us with the boiler symptoms and we’ll advise on the earliest available appointment. For faults that cannot wait, use our dedicated emergency boiler repair service.
Can you repair a boiler with no heating?
Yes. No heating can be caused by faulty controls, pumps, motorised valves, low pressure, sludge, circulation problems or an internal boiler fault.
Why does my boiler keep losing pressure?
Pressure loss can be caused by leaks, expansion vessel faults, pressure relief valves, damaged seals or hidden pipework leaks. Our boiler losing pressure guide explains the common causes in more detail.
Is a boiler repair different from a boiler service?
Yes. A boiler repair fixes an existing fault. A boiler service is preventative maintenance carried out on a working appliance.
Which boiler brands do you repair?
We regularly repair Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Potterton, Alpha, Viessmann and many other domestic gas boilers.
Should I turn my boiler off if it’s leaking?
If water is leaking from the boiler, turn it off if it is safe to do so and contact a Gas Safe engineer. Do not remove the casing or touch internal components. If you smell gas, leave the property, avoid operating electrical switches and contact the National Gas Emergency Service on 0800 111 999.
Is it worth repairing an old boiler?
That depends on the age of the boiler, the type of fault, previous repair history and availability of replacement parts.
Do you cover areas outside Croydon?
Yes. Alongside Croydon we regularly work in South Croydon, Thornton Heath, Selhurst, Addiscombe, Norbury, East Croydon, West Croydon and surrounding South London areas.
