Getting your gas boiler serviced is crucial to keeping it in good working order.
Take a look at your boiler’s manufacturer guidelines to find out how often a service is recommended, and if you don’t have access to these, we’d advise getting your boiler serviced annually – or in line with the manufacturer’s guidelines.

Although your gas boiler should be serviced in line with manufacturers instruction, it’s a good idea to get your gas boiler serviced ahead of the winter period, if not already done so. Any unplanned breakdowns could leave you without heating when you need it the most and it’s often a busy period for Gas Safe registered engineers.
Boiler Maintenance Tips
There are a few things you can do in-between services to look after a boiler and help prevent breakdowns. Follow our tips to take care of your gas boiler:
- Check the central heating system water pressure where applicable – Boilers can lose system pressure as they age. Check the pressure gauge and top it up if it’s too low
- Bleed excess air from your radiators – You can tell if your radiators need bleeding if they’re colder at the top than the bottom, meaning excess air is trapped in the system. This will put additional strain on your boiler. Note that if you need to do this regularly it’s likely hiding a wider issue and you should ask a Gas Safe registered engineer to check the system
- Lag the pipes – When it gets very cold your boiler’s external condensate pipe can freeze and your boiler will cut out. You can prevent this by asking a Gas Safe Engineer to insulate your condensate pipe
- Even with proper care and maintenance on your part, the best way to keep your gas boiler going is by having it regularly serviced by a Gas Safe registered engineer
