Water quality checks

The introduction of new British Standards has made it mandatory to test water quality when carrying out a boiler service. This new regulation aims to ensure that the water running through your central heating system is safe, efficient and clean. The inspection will assess the quality of the water, including its chemical balance, pH level, and the presence of any debris or contaminants that may negatively impact the central heating system's efficiency.

Over time, debris and other contaminants can build up within the central heating system, causing significant problems for the system and the boiler. For example, the accumulation of debris can cause blockages and reduce the flow of water through the pipes, reducing the heating system's overall efficiency. When your heating system isn't running efficiently, your boiler will need to work harder to heat your home, increasing the likelihood of a breakdown and reducing the lifespan of the boiler.

By carrying out system water quality checks as part of your boiler service, our team of experts can help identify any issues with the central heating system that may lead to costly repairs or replacements. In addition, this inspection will enable us to detect and remove any debris or contaminants that may be impacting the system's efficiency and performance, ensuring that your boiler runs smoothly and your heating system operates at peak efficiency.

What you’ll notice after your boiler service

If you don’t service your boiler regularly unnoticed issues could be causing hidden damage to your boiler. The initial cost of a boiler service is likely to save you money on repair work and replacements in the future. There are a few things you will notice after giving your boiler a consistent annual service:

  • Reduced energy costs

As your boiler increases in age, it will need to work much harder in order to heat your home. Regular service can slow down this process and keep your bills lower for longer along with delaying the need to replace your boiler for increased heating costs. 

  • Fewer repair costs 

It goes without saying that a complex machine like a boiler needs to be maintained in order to keep it running at maximum efficiency. In addition to this, a well-maintained boiler has less chance of breakdown and less chance of needing to call out an engineer for repair work.  

  • The longevity of your boiler will increase

The upfront cost of a new boiler is a large and necessary expense as your boiler reaches the end of its life. Prolonging the life of your boiler is the best way to save money in the long term by delaying the need for a newer model. 

Other benefits of a boiler service

It’s important to note other factors that may not be as noticeable. One example is the increased safe operation of your boiler. Carbon monoxide leaks throughout your home could cause unspeakable damage. As part of our service, we check for leaks and ensure your boiler is in keeping with the latest regulations designed to keep you safe.

Some boiler manufacturers’ warranties also require you to book an annual boiler service in order to keep your warranty valid. 


In addition to offering boiler services, we also provide powerflushing as an essential step in ensuring the longevity of your heating system. Powerflushing is a comprehensive cleaning process that removes sludge, rust, and other debris from your heating system. This process is crucial in maintaining the efficiency of your heating system, as it helps to remove any blockages or restrictions, ensuring that the water flows freely and efficiently.

During a powerflush, our heating engineers in Charlton will use a combination of chemicals and high-pressure water to flush out any debris from your central heating system. This process will leave your system clean and running at optimal efficiency, reducing the likelihood of costly repairs and increasing the lifespan of your boiler.

Moreover, steps are taken during the powerflushing process to prevent any build-up of debris in the future. By installing a magnetic filter or an inhibitor, we can help to prevent the accumulation of debris in the system, ensuring that your heating system remains efficient and running smoothly.
