During the appointment, our Gas Safe registered engineers inspect the boiler and flue, check operating pressure, test safety devices and examine internal components.

Baxi boilers should be checked regularly to make sure the appliance remains safe and continues to operate as intended. We provide annual servicing for Baxi combi, system and heat-only boilers across London, with checks carried out by Gas Safe registered engineers.

A typical service involves examining the boiler and flue, checking gas pressure, testing safety controls and inspecting internal components. The engineer can also clean relevant parts where needed and check for signs of corrosion, wear or other developing issues. Regular servicing is particularly useful for older boilers, where early signs of deterioration may otherwise go unnoticed. If your Baxi boiler has not been serviced within the last year, we can arrange a professional service in London.

Our Gas Safe registered engineers assess how the boiler is operating and inspect the components that affect safe and reliable performance.

Combi Boiler Service

A combi boiler provides both central heating and hot water from a single appliance, so keeping it properly maintained is important for both functions. We service combi boilers across London, checking the appliance and associated controls to make sure it is operating safely.

During a service, our Gas Safe registered engineers inspect the boiler, flue and internal components, check gas pressure and test the safety controls. The burner, heat exchanger and other accessible components are cleaned where required. We also check for signs of deterioration that could affect performance later. Annual servicing gives you a chance to address developing issues before they become disruptive and helps keep your combi boiler ready for the heating season.

System Boiler Service

A system boiler forms part of a wider heating arrangement that normally includes a hot water cylinder, controls and associated pipework. Servicing therefore involves more than simply checking the boiler itself. We provide system boiler servicing across London, assessing the appliance and relevant parts of the heating system.

Our Gas Safe registered engineers inspect the boiler, flue and connections, check operating pressure and test safety controls. They also examine key components and clean relevant areas where required. The wider system can be checked for signs that may affect heating or hot water performance. Regular servicing is particularly useful for system boilers because problems elsewhere in the installation can influence how the appliance operates.

 Trustindex verifies that the original source of the review is Google. Rapid response from Armand to a Google Local Services request. Good comms via WhatsApp. Same day attendance. I live in a tricky area for parking but Armand managed that without complaint. Quickly diagnosed and resolved the problem with my heating system, made efficiency improvements, and taught me a few things along the way for future reference. The following morning I had a worsening situation due to air and pressure changes settling in the system overnight (unavoidable) but Armand was responding to my messages from 6:51am and helping me to relay instructions to my tenant in real time to apply a final fix. The heating system is now working incredibly effectively and efficiently. I'm burning hardly any gas to keep the property warm. Gas bill reducing substantially now. As with everything these days, skilled people don't come cheap; you get what you pay for and I would recommend Armand to others.

FAQ:

How often should I schedule a boiler service near me?

It’s best to have your boiler serviced once every 12 months. An annual service keeps your boiler running safely and efficiently, helps prevent breakdowns and ensures your manufacturer warranty stays valid. Most boiler brands require a yearly service as part of their warranty conditions, so skipping it can mean losing cover if something goes wrong later.

Regular servicing allows an engineer to spot early signs of wear before they turn into bigger issues. For example, small leaks, blocked filters or pressure faults can be fixed quickly during a service visit preventing costly repairs or a full breakdown in winter.

If your boiler is older or used heavily, it’s worth scheduling a service before the cold season starts. That way, you can be confident your heating and hot water will work properly when you need them most.

For landlords, an annual boiler service also helps meet safety responsibilities and keeps the property compliant with gas safety regulations. It’s a simple but important way to protect your home, save energy, and extend the life of your boiler.

What does a typical boiler service London include?

A standard boiler service in London involves a full inspection, cleaning and performance check to make sure your boiler is safe and working correctly. The engineer starts by checking for gas or water leaks, testing the boiler’s controls and inspecting the main components for signs of damage or wear.

The flue system is also checked to ensure it’s properly fitted and venting gases safely. The engineer will then clean the burner, heat exchanger and internal parts to remove any carbon build-up or debris. These steps help the boiler burn fuel efficiently and reduce the risk of faults.

Pressure levels and safety devices are tested next, followed by a check of the system’s overall operation. Finally, the engineer records the results in a service report and confirms that the appliance meets current safety standards.

If any issues are found, you’ll be told exactly what they are and what repairs might be needed. The goal of the service is to keep the boiler in good working order, prevent breakdowns, and make sure your heating system is running as efficiently as possible.

Are your boiler services in London Gas Safe certified?

Yes all our boiler servicing in London is carried out by Gas Safe registered engineers. This certification is a legal requirement for anyone working with gas appliances in the UK. It ensures the engineer has been properly trained and approved to work safely with boilers, gas pipework, and flues.

When our engineers perform a service, they follow official Gas Safe procedures checking for leaks, testing combustion and verifying that your boiler is operating safely. At the end of the visit, they’ll record the work done and confirm the appliance meets all safety standards.

We always encourage customers to check their engineer’s Gas Safe ID card before the job starts. The card shows the engineer’s name, photo, registration number and the specific types of gas work they’re qualified to do. You can also verify this information directly on the official Gas Safe Register website.

Having your boiler serviced by a certified professional keeps your home safe and ensures your manufacturer warranty remains valid. It’s the only way to be certain your gas boiler is being maintained to the correct legal and safety standards.

Do you offer boiler servicing near me for all boiler types?

Yes, we service all types of domestic boilers, including combi boilers, system boilers and regular (heat-only) boilers. Our engineers are experienced with all major makes and models like Worcester Bosch, Vaillant, Ideal, and Baxi and more.

Each boiler type has its own setup and maintenance requirements. For example, combi boilers are compact and don’t use tanks, so servicing focuses on the internal components like the burner, heat exchanger and pressure system. System boilers and regular boilers, on the other hand, include external parts such as hot water cylinders or tanks, which also need to be checked to ensure the system works efficiently.

During servicing, our engineers inspect and clean the boiler, test safety controls and make sure the system is running efficiently. We also check for leaks, blockages and any signs of wear that could cause problems later.

Our team has the training and equipment to service it properly. We aim to keep your heating system reliable, safe and ready to perform all year round.
