Common Emergency Boiler Problems We Fix

At MJB Servicing Ltd, we specialise in diagnosing and repairing a wide range of urgent boiler issues. Whether it’s a minor fault or a complete heating failure, our expert engineers are equipped to get your system back up and running — fast.

Here are some of the most common boiler problems we’re called out to fix:

🔧No Heating or Hot Water

This is the most frequent emergency we handle. If your boiler isn’t producing heat or hot water, it could be due to a number of underlying faults — from broken components to low pressure or ignition failure.

🔥 Boiler Not Igniting or Turning On

If your boiler won’t fire up, it may be due to issues with the ignition system, gas supply, or electrical components. We’ll identify the fault and safely restore function.

💧 Leaking or Dripping Boilers

Water leaks can lead to corrosion, pressure loss, and damage to surrounding areas. Whether it’s a worn-out seal or corroded pipe, we’ll stop the leak and fix the root cause.

🧪 Low Boiler Pressure

When boiler pressure drops, it often causes the system to shut down. We’ll diagnose why pressure is falling and safely restore it to the correct level.

🔊 Strange Noises (Banging, Gurgling, or Whistling)

Unusual noises could signal trapped air, limescale build-up, or a failing pump. These problems should be addressed promptly to avoid long-term damage.

❄️ Frozen Condensate Pipes

Frozen pipes are common in winter and can cause the boiler to shut down. We’ll thaw the pipe safely and ensure proper insulation to prevent future issues.

🕒 Faulty Thermostats or Timers

If your heating schedule isn’t working or your thermostat is inaccurate, we’ll repair or replace it to give you full control over your comfort.

⚠️ Error Codes & Warning Lights

Modern boilers often display error codes when something’s wrong. Our engineers can quickly interpret these codes and perform the necessary repairs.
