Having heating and hot water in your home is crucial, which is why it is essential to ensure that you get your boiler annually serviced so that it can perform to its maximum efficiency.

Have your boiler serviced annually ensures greater reliability of your boiler, increases its lifespan, enhances safety for you and your home, and ensures that your boiler warranty is protected.

A typical boiler service consists of:

  • A full inspection of your boiler’s components by a Gas Safe Engineer
  • An inspection of the main injector, spark probe, and burner to the heat exchanger, electrical connections, and controls.
  • Your Gas Safe Engineer should also check all the seals, pipework, and combustion releases to make sure that your boiler is functioning at the correct pressure
  • Replacement of any damaged or worn parts
  • Clean the necessary components to ensure your boiler is performing as effectively as possible.

When should you arrange a boiler service?

Your boiler manufacturer will often mention that your boiler requires an annual service to ensure maximum efficiency and to protect your warranty. If you don’t get an annual service, you could end up paying for repairs, which can be quite costly depending on the boiler fault.

Other signs that you should look out for that indicate that you need a boiler service are:

  • If you see increased condensation in the room where your boiler is located
  • Black stains or marks around your boiler
  • The flame in your boiler changing from blue to yellow.

If you start to feel nausea, tiredness, dizziness, start vomiting or having headaches, stomach pains or have difficulty breathing, please call your Gas Engineer immediately and vacate the property, as this could be a sign of Carbon Monoxide poisoning.
