A regular boiler service will extend the performance and lifespan of your boiler. Furthermore, investing in boiler inspection and testing can ensure the safety of your family and property. For your convenience, we offer two options -standard boiler service and boiler service plus- performed by local Gas Safe Registered engineers.

Whether you need a one-off boiler service to check the current condition of your boiler or it's time for the regular annual boiler service session, we have the right solution for you.

Standard Boiler Service

  • The Gas Safe Registered engineer will inspect your boiler, its parts and controls to ensure they are working properly;
  • We will visually examine for any signs of leaks or corrosion.
  • Next on the list are the seals. If any issues are found, the technician will replace them to prevent gas leaks. 
  • The heating engineer will inspect the ignition and the heat exchanger.
  • Additionally, we will perform a flue analyser (FGA) test to ensure the burner pressure and combustion are at appropriate levels.

Boiler Service Plus

The boiler Service Plus package includes all the tasks of the Standard boiler service and the following additional checks:
  • Inspect the radiators for leaks due to malfunctioning valves;
  • The radiators will be drained to maintain the proper pressure, and new fluid will be added if necessary;
  • Check if the radiators are heating evenly.

Annual boiler servicing to ensure your home safety

The risk of carbon monoxide poisoning is very real when you have a neglected boiler that has not been inspected and serviced regularly. As it is odourless and colourless, a poisonous gas leak is practically undetectable without special gas leak detectors. So, to keep your boiler running safely and efficiently is essential to arrange an annual service and install carbon monoxide alarms.

Availability & coverage

You can book your boiler service session anytime, including on public and bank holidays. You can check the real-time availability and prices using our booking form or the mobile GoFantastic app. The heating engineers serve the London M25 zone.

Legal compliance 

As a landlord, you are obligated by law to ensure the safety of your tenants, so we managed to design service packages to suit your needs and save you money. Now you can get your gas safety certificate and gas boiler service on the same day.

Frequently asked questions

Q: Do I need a boiler service or repair? 

A: The main difference is that a boiler servicing session can help you prevent the need to hire a boiler repair specialist. During your boiler servicing session, the engineer will test and inspect your boiler and repair only minor issues. Still, if he finds any potential problems, he will inform you in detail so you can book a boiler repair specialist.

Q: Gas safety certificate or boiler service - what to choose?

A: If you feel confused about which one is the right for you, let's clarify it. The boiler service covers all boilers, not only gas burning. Also, the engineer may replace a seal or the old fluid.  For a difference, the gas safety checkup covers all gas appliances in your property, including gas ovens, gas hobs and gas fireplaces. However, the key difference is that the specialist will only point out the potential issues without attempting to fix them. 

Q: Do you offer any boiler cover plans?

A: Yes, we do offer two boiler insurance options to suit the needs of homeowners and landlords. Just contact us and ask about our boiler cover and central heating plans.

Q: What is the best time to arrange my annual boiler service appointment?

A: We recommend getting your boiler serviced during the summer or the early autumn due to the lower demand for heating engineers at that time of year.   Leaving boilers inactive for extended periods can lead to heating system stagnation and blockages resulting in more repairs. Early servicing will give you enough time to deal with all the issues.

Q: What is your coverage? 

A: The service is available in the entire London M25 zone, but you can quickly check the availability in your area by using our booking form or calling us.

Q: What to do if I smell gas in my property? 

A: There are four steps you can take if you smell gas or suspect a leak:

  • ensure that all electrical appliances and lights are off
  • open your windows and leave the property
  • call the National Gas Emergency Service hotline (0800 111 999) 
  • wait near the area until qualified personnel arrives.
