Our Process for Boiler Repair Services
Step 1: Thorough System Diagnosis
We begin by inspecting your boiler from top to bottom—burners, heat exchanger, valves, thermostat, and pressure levels. This detailed checkup allows us to accurately determine the issue and avoid unnecessary replacements or repairs.
Step 2: High-Tech Diagnostic Testing
Using modern diagnostic tools, we assess the boiler for ignition problems, gas leaks, water pressure issues, and other faults. This step ensures we’re resolving the actual problem, not just its symptoms.
Step 3: Transparent Repair Recommendations
Our technicians take time to explain exactly what’s happening with your system. We outline available repair options and offer clear pricing before any work begins, so you know what to expect.
Step 4: Fast, High-Quality Part Replacements
If repairs require new components, we only install top-grade parts like gas valves, thermostats, or circulator pumps. Our vehicles are stocked with common boiler components, so we can complete most repairs on the first visit.
Step 5: Efficiency Optimization & Cleaning
We finish with a full tune-up to improve your boiler’s efficiency. By cleaning essential parts like filters, burners, and the heat exchanger, we help your system run cleaner and reduce energy waste.
Step 6: Final Performance & Safety Checks
Before we leave, we perform a final series of safety and function tests. We confirm the boiler ignites properly, gas is flowing as it should, and pressure levels are within safe limits—ensuring your heating system is ready to perform reliably.
Common Boiler Issues
Even with regular care, boilers can still develop problems over time. Below are some of the most common issues that homeowners in London may experience:
Boiler Not Heating Properly
- Low Water Pressure – Without enough pressure, hot water can’t move through your heating system efficiently, leading to uneven warmth or cold spots.
- Faulty Thermostat – A malfunctioning thermostat can cause irregular temperatures, short cycling, or a complete lack of heat.
- Air or Debris Blockages – Air pockets or built-up sludge in the radiators and pipes can reduce or stop the flow of hot water throughout your home.
Loud Noises from the Boiler
- Banging or Kettling Sounds – These noises usually come from limescale or debris inside the heat exchanger, which can cause localized overheating.
- Whistling or Gurgling – This may be due to trapped air, low pressure in the system, or flow restrictions in the pipes.
Water Leaks or Pressure Problems
- Leaks from the Boiler – These often result from aging seals, corroded connections, or excessive pressure inside the system.
- Fluctuating Pressure – Issues like a leaking expansion vessel, a damaged pressure relief valve, or hidden water leaks can cause the pressure to rise or fall unexpectedly.
Ignition or Pilot Light Failures
- Gas Supply Issues – A closed or faulty gas valve can interrupt the ignition process.
- Worn-Out Ignition Parts – Components like electrodes, sensors, or thermocouples may wear out over time and need replacement.
If any of these problems sound familiar, M&K Heating and Air Conditioning has been helping homeowners in London since 1983 with dependable boiler repair services to restore home comfort quickly.

How Often Should I Get My Boiler Serviced?
It’s recommended to service your boiler once a year. Annual boiler maintenance helps reduce the risk of unexpected issues, improves efficiency, and can extend your system’s overall lifespan. A typical boiler service includes cleaning, pressure checks, leak detection, and a system performance evaluation.
How Long Does a Boiler Last?
Most boilers can last 15 to 20 years with proper upkeep. The durability depends on the quality of the equipment, how it was installed, and how often it receives maintenance. Regular professional servicing can keep a boiler running smoothly for many years.
Should I Repair or Replace My Boiler?
If your boiler is aging, unreliable, or requiring frequent repairs, it may be time to consider a replacement. Units over 15 years old that no longer perform efficiently could lead to higher energy bills and more repair costs. Upgrading to a newer model can be a more cost-effective solution in the long run.
How Much Does It Cost to Repair a Boiler?
Boiler repair costs vary depending on the issue and your specific boiler model. Simple fixes like adjusting the thermostat or sealing a minor leak are generally less expensive, while more serious problems, such as a faulty heat exchanger or failed gas valve, can cost more due to part and labour requirements.
