Boiler Service, Maintenance & Repair

It is very important to have your appliance serviced annually. It can help identify problems before they get out of control and it gives you an idea on how efficient your appliance is, and above all how safe it is. We service and install all natural Gas, Oil and LPG boilers.

Here is what's included in all our boiler services, safety checks and landlord CP12 certificates:

  • General visual check of appliance
  • Check working gas pressures to make sure your appliance is getting enough gas
  • Check for debris in the heat exchanger and clean if necessary
  • Use of the flue gas analyser to check efficiency and make sure carbon monoxide levels are below the danger level and adjust if necessary
  • Drop test on gas pipe carcass to ensure you don’t have a gas leak in the pipework or appliance
  • Spillage check (if required) to make sure the flue is taking the products of combustion away and all filters cleaned to prevent incomplete burning which leads to carbon monoxide (CO)
  • We will make sure your gas pipe and water pipe are adequately earth bonded
  • Any advice we feel may be useful or answer any questions you have
  • Certificate for your records detailing our visit this allows us to keep track of your safety check and send you a reminder in 12 months
