    You should never see water coming from your boiler. If you do, it might be a sign that an internal part has failed. While it’s not necessarily dangerous, you should switch off your boiler to prevent your electrics short-circuiting and to stop water damaging your home or belongings. Don’t try to fix a boiler leak yourself. Give us a call to take a look.

    Gurgling, banging or whistling sounds should probably be looked at. They’re likely to be caused by air or a build-up of material inside your central heating. It’s not a dangerous situation but if left unattended, a build-up could lead to a boiler breakdown and expensive repairs.

  • boiler is running
  • Scorching or brown/black marks on the boiler
  • A musty smell or signs of soot
  • More condensation than normal on your windows

If you suspect carbon monoxide or a gas leak you should immediately switch off your gas supply at the meter, open your doors and windows to let air into your home, and leave the house. Stay outside and don’t use electrical switches or naked flames until the experts have given it the OK.

If this happens frequently, especially if it’s combined with any of the signs above, your boiler should be checked over without delay.

Low pressure, a thermostat issue, or maybe a lack of water in the system could cause your boiler to switch itself off. If you can’t identify the source of the problem, a Gas Safe engineer will. As with all boiler faults, it’s better to nip it in the bud.
