A well-functioning boiler is at the heart of every warm and comfortable home, especially during the colder months in the UK. But while many homeowners rely on their boilers daily, few understand the importance of boiler servicing and what it actually involves.
In this post, we’ll explain exactly what’s included in a standard boiler service, why it’s essential for your safety and efficiency, and how regular boiler servicing can save you money in the long run.
What Is Boiler Servicing?
Boiler servicing is a professional inspection and maintenance procedure carried out by a qualified Gas Safe registered engineer. It ensures that your boiler is working efficiently, safely, and in accordance with UK regulations.
Most manufacturers recommend that you service your boiler once every 12 months to maintain your warranty and prevent unexpected breakdowns.
What’s Included in a Boiler Service?
During a standard boiler service, an engineer will follow a detailed checklist that typically includes:
✅ Visual Inspection
The engineer will check for any obvious signs of wear and tear, corrosion, or leaks. This includes examining the boiler casing, pipework, flue, and ventilation.
✅ Pressure Check
Boilers need the correct pressure to operate efficiently. The engineer will check the system’s pressure and adjust it if necessary.
✅ Safety Controls Test
The boiler’s safety features, such as the thermostat, pressure relief valve, and flame sensor, will be tested to ensure they are functioning properly.
✅ Internal Component Cleaning
The engineer will open the boiler casing to inspect and clean essential internal components like the burner, heat exchanger, and fans. Build-up of debris in these areas can reduce efficiency and increase the risk of breakdown.
✅ Flue and Combustion Check
This step ensures that the boiler is burning fuel safely and efficiently. A flue gas analyser is used to check carbon monoxide levels and combustion efficiency.
✅ Gas Leak Check
The engineer will inspect the system for any gas leaks and ensure the boiler is operating safely in line with gas safety regulations.
✅ Service Record and Recommendations
Once the inspection is complete, the engineer will provide a service report and advise on any recommended repairs or replacements.
Why Boiler Servicing Is Essential
Safety First
A faulty boiler can leak carbon monoxide — a deadly, odourless gas. Regular boiler servicing ensures that your appliance is safe and any potential hazards are identified early.
According to the NHS, over 200 people are admitted to hospital every year with suspected carbon monoxide poisoning. That’s why safety should always come first.
Save Money on Energy Bills
A well-maintained boiler runs more efficiently, which can lower your gas usage and reduce your energy bills. Over time, dirt and debris can build up inside the system, forcing your boiler to work harder. Regular boiler servicing helps maintain peak performance.
Avoid Unexpected Breakdowns
No one wants their boiler to fail in the middle of winter. Annual servicing helps detect and fix minor issues before they become major, costly repairs.
Maintain Your Warranty
Many boiler manufacturers require proof of annual boiler servicing to keep the warranty valid. Skipping a service could mean paying out-of-pocket for repairs that might otherwise have been covered.
Essential for Landlords
Landlords are legally required to have all gas appliances, including boilers, inspected every year. This is part of the Gas Safety (Installation and Use) Regulations 1998. You can read more about landlord responsibilities on the official HSE website.
How Much Does Boiler Servicing Cost?
In the UK, a standard boiler service usually costs between £70 and £120, depending on your location and the type of boiler you have. While this might seem like an added expense, it’s a small price to pay compared to the cost of a major repair — or even a replacement boiler.
When Should You Book Your Boiler Service?
The best time to book a boiler service is during the summer or early autumn. Engineers are generally less busy at this time, and it ensures your system is ready to go before winter arrives.
