Is it time for your annual boiler service?

In order to ensure that your boiler remains gas safe and in good working order for as long as possible, it is important that you get your boiler serviced annually. All gas appliances should be serviced every 12 months.

Boiler Servicing London


A boiler that hasn’t been serviced by a gas safe registered engineer for more than a year could be potentially very dangerous, as faulty boilers could emit poisonous carbon monoxide. As well as raising safety concerns, a boiler that hasn’t been serviced regularly may be running inefficiently which can increase your energy bills. Furthermore, in order to maintain the validity of your warranty, many boiler manufacturers require you to get your boiler serviced yearly.


Our gas safe boiler engineers will conduct a thorough inspection of your boiler. A typical service usually includes but is not limited to:

– Gas meter inspection
– Visual inspection of your gas appliance(s) – we will thoroughly check your system and flue. The ventilation will be checked to ensure that it is adequate and we make sure that no leaks are detected.
– Verifying parameters against the manufacturer’s instruction
– Removal of foreign debris
– inspect CO (carbon monoxide) detector
– Newer boiler manufacturers have additional mandatory checks

After our engineers service your boiler, they will let you know if they have identified any problems such as corrosion or leaks that will require repairs to promote the health and longevity of your boiler.  


Our service cost combined with a Gas Safety Certificate (also known as a CP12) and the service checks on a domestic condensing type boiler starts at £170.00.

If your boiler fails the service checks and is within its’ warranty period it is referred to the manufacturer.

The manufacturer may repair or replace the boiler under their warranty.

We will only quote for additional maintenance on your boiler if the service checks indicate a problem, incorrect installation or if the boiler cover has expired.

Servicing of non-condensing type boilers is charged as time on site. Our rates are hourly with a minimum charge of 1-hour. They’re always serviced according to the manufacturer’s instructions.

Residents should keep their boiler commissioning and servicing instructions safe and have them available for the gas engineer to refer to and complete. Our team can help by providing you with new boiler documentation if yours is misplaced. By using our service, not only will your central heating be running more efficiently, problems which lead to a boiler repair can be avoided. A Heating system works best when it is maintained well and service the boiler is a vital component amongst the list of maintenance checks.


We advise our customers to take a number of actions on a daily/weekly basis to keep their boilers healthy between their annual checks.

-Get a carbon monoxide alarm and a fire alarm fitted near your boiler and regularly check to see if it is working.
-Familiarise yourself with the manufacturer’s handbook that came with your boiler. Be sure to keep this handbook safe and in a place that is easy to locate.
-Check the water levels of the boiler to ensure that it doesn’t drop too low, as this can have a negative effect on the functioning of your boiler.
-Inspect the temperature and pressure of your boiler. If you notice any significant changes, get in touch with us immediately on 07754259768 and we will get an engineer out to you ASAP.

Over the years we have rectified countless boilers that were found immediately dangerous under gas safe regulations and can be found in the unsafe situations procedures document.

By having one of our engineers supply and install a recommended carbon monoxide (CO) detector in your property you’ll be alerted to carbon monoxide (CO) leaks.
