How often should I service my boiler?

You should service your boiler once a year (every 12 months) at minimum . Annual servicing is recommended by manufacturers and Gas Safe authorities to keep your boiler running safely and efficiently. Many warranties also require yearly service, and for landlords an annual gas safety check (essentially a service) is a legal must. Ideally, get the service done before winter each year – for example, in late summer or early autumn – so you know your boiler is ready for the colder months.

Is boiler servicing really necessary if everything seems fine?

Yes, absolutely. Even if your boiler is running without obvious issues, an annual service can uncover hidden problems or wear-and-tear that you wouldn’t notice day-to-day. Crucially, servicing checks safety aspects – for instance, ensuring there are no gas leaks or risk of carbon monoxide leakage. It’s a preventative step that catches issues early, improves efficiency, and ensures your boiler stays safe. Skipping service might save a bit now, but it greatly increases the risk of unexpected breakdowns or dangerous faults later.

Do I need a Gas Safe engineer to service my boiler?

Yes – in fact, it’s legally required. Always have your boiler serviced by a Gas Safe registered engineer . Gas Safe engineers are the only people qualified to work on gas appliances in the UK. It’s dangerous (and illegal) for anyone else to tamper with a gas boiler. Using a Gas Safe engineer ensures the job is done correctly and safely. Before hiring, you can ask for the engineer’s Gas Safe ID or check the Gas Safe Register online to confirm their credentials.
