Understanding Boiler Servicing & Repairs

Recognising when you require a boiler service versus a heating repair is vital. Boiler servicing, akin to a car’s MOT, is an annual check-up for safety, efficiency, and performance, including replacing specified parts as instructed by the manufacturer. Mainly, a boiler service is preventive, catching issues before a complete failure, the annual MOT for your boiler!

Boiler repairs, however, are required when a breakdown occurs and your boiler stops producing heating or hot water. Our standard boiler servicing and “Cosy Plan” service plan does not cover repairs or faulty boilers, focusing instead on preventive maintenance.

The Warm & Cool London Boiler Plan

We now offer the Warm & Cool London Boiler Plan for properties that require that little extra help, support & service.

Inc WCL London Boiler Service

Checking the safety & performance of your boiler is standard procedure for our team of experienced service engineers. Every boiler may have slightly different instructions but mostly include the following, testing safety devices, flue gas analysis, checking gas consumption, water leaks, cleaning the condensate trap and most importantly, testing that there are no gas leaks!

Including all servicable parts

The boilers manufacturer’s instructions will list the year or point that a main service is required. Our Boiler Plan includes the main service gaskets and electrodes when needed.

Upgraded System Water Protection

Recent changes in building regulations now require boiler servicing, including testing the water flowing through the heating system. Our Boiler plan includes new protective chemicals if required after testing the heating systems’ water.

Safety & Performance Tests

Every boiler may have slightly different instructions but mostly include the following. The installation meets regulations, testing safety devices are still functioning, flue gas analysis, checking gas consumption, water leaks, cleaning the condensate trap and most importantly, testing that there are no gas leaks!

WCL - Boiler Service Page - Gas Rating

Gas Rating Explained

Gas Rating confirms that all other test results recorded during the boiler service are measured as the boiler runs at full capacity. The gas rating test also ensures the boiler’s Gas consumption is correct and as listed in the manufacturer’s specifications, confirming efficiency and safety.

WCL - Boiler Service Page - FGA Flue Test

The FGA Flue Tests

The flue gas analysis tests assess the boiler’s combustion emission levels. These tests confirm the boiler is burning correctly or identify harmful gases like carbon monoxide.

WCL - Cleaning the trap

Cleaning the Trap

Condensing boilers use a device known as a condensate trap to prevent harmful gases from escaping into the condensate pipe. Cleaning the condensate trap removes residue and prevents blockages. If not cleaned, a blocked condensate trap will cause the boiler to shut down.

WCL - System Water Quality

System Water Quality

Checking the heating systems’ water has long been good practice, but the recent changes in building regulations now require boiler servicing to include testing the water flowing through the heating system. Although the standard service includes the testing of system water, additional chemicals may be required after the test. Chemical dosage is not included in the standard service.

WCL - Expansion Recharge

Recharge expansion vessel

From time to time, the boiler or heating system expansion vessel will need pumping up to the correct pressure. A quick test on service may identify an imminent issue.

WCL - Cleaning the Heat Exchanger

Cleaning the Heat Exchanger

Cleaning the heat exchanger prevents debris buildup and optimises the heat transfer from the burning gas to water. Cleaning the heat exchanger ensures maximum efficiency and longevity of the boiler.

WCL - Boiler Main Service

Boiler "Main" Service Requirements

The boilers manufacturer’s instructions will list the year or point that a main service is required. Unlike the standard annual service, a main service often requires that gaskets and electrodes are replaced as part of the service. This is normally around the fifth-year service but could depend on a performance test.

Frequently Asked Boiler Service Questions

When you book a boiler service, you can expect a thorough inspection of your boiler, including a check of all components to ensure they function correctly and safely. A boiler service is an essential part of maintaining the safety and efficiency of your heating system and help to prevent costly breakdowns and repairs in the future.

A boiler service typically involves thoroughly inspecting the boiler to identify any issues or potential problems. This includes checking the boiler’s internal and external components, cleaning any dirty or clogged parts, and testing the pressure and gas flow. The gas engineer will also check the safety controls and ensure that the boiler is working efficiently and safely.
A well-maintained boiler will also help to reduce energy bills and extend the life of the system, providing peace of mind for homeowners.

The radiators are not typically checked or bled during a standard boiler service. If you notice that some of your radiators are not heating up properly, it may be a sign that they need to be checked or bled. This service may be able to add this to your boiler service appointment at an additional charge.

A standard boiler service typically takes around 45-90 minutes to complete. However, the time may vary depending on the age and condition of the boiler. Some factors that may impact the service’s length include the boiler type, its make and model, and the complexity of the heating system. Generally, it is recommended to schedule a boiler service annually to ensure that it runs safely and efficiently.

It is recommended to have your boiler serviced annually to ensure its safe and efficient operation.

Boilers that are not serviced regularly can become inefficient and unsafe, potentially leading to expensive repairs or even dangerous situations like gas leaks or carbon monoxide poisoning.
The boiler’s lifespan may also be shortened, requiring replacement earlier than expected. Additionally, if the boiler’s warranty requires annual servicing, having it serviced can ensure the homeowner pays for repairs or replacements out of pocket. 

While any company may offer boiler servicing, it is vital to ensure that the company you choose has qualified and experienced engineers who are registered with the Gas Safe Register.
If your boiler is under manufacturer’s warranty, it may require the Gas Safe engineer to be accredited by the manufacturer to complete the warranty service on your boiler.

After a boiler service, the engineer provides a service report that outlines the work carried out and any recommendations for repairs or improvements if required. This report can be used as proof that the boiler has been serviced.

According to most boiler manufacturers, not having your boiler serviced annually can void its warranty or guarantee. Therefore, it is important to have your boiler serviced every year to ensure its safe and efficient operation, as well as to maintain the validity of your warranty.
