5 Common Reasons Why Your Boiler Isn’t Working

If your boiler suddenly stops working, it’s stressful—especially during a chilly Bedfordshire winter. At Nexus Plumbing & Heating, we’ve helped countless Biggleswade homeowners get their heating back on quickly. Here are five of the most common causes of boiler breakdowns:

  1. Low Boiler Pressure
    If your radiators aren’t heating up and the pressure gauge is sitting below 1 bar, your boiler may simply need topping up.
  2. Thermostat Issues
    A faulty or outdated thermostat can stop your heating from turning on at the right time.
  3. Frozen Condensate Pipe
    A very common issue during cold snaps. A frozen condensate pipe can stop your boiler from working completely.
  4. Pilot Light or Ignition Problems
    If your boiler keeps failing to ignite or the flame won’t stay on, it may be due to a faulty ignition system or blocked jet.
  5. Worn-Out Components
    Over time, pumps, fans, and valves wear down. Regular boiler servicing can prevent unexpected failures.
