Picture this: it's the middle of winter, and you’re cosied up on the couch with a hot chocolate, enjoying your favourite Netflix show.
Suddenly, the heating cuts out. Your boiler has decided to take a holiday at the worst possible time. Avoiding this nightmare scenario is just one reason why regular boiler servicing is crucial.
But how long does a boiler service take, and what does it involve? Let’s dive into the nitty-gritty of boiler servicing to ensure you’re never left out in the cold.
Around how long does it take to have a boiler serviced?
On average, a standard boiler service takes about 30 to 60 minutes. This should always be carried out by a Gas Safe registered engineer.
However, this duration can vary depending on several factors. For instance, if it’s been a while since your last service or there are underlying issues, the service might take longer.
What should happen during a boiler service?
A thorough boiler service involves several crucial checks and tasks to ensure your boiler is running efficiently and safely.
Here’s a rundown of what a Gas Safe registered engineer will typically do during a boiler service:
Visual inspection
The first step is a visual inspection. The engineer will check the boiler and its components to ensure everything looks in good condition. This includes inspecting for any obvious signs of damage, wear, or leaks.
Flue check
The flue, which is the pipe that removes exhaust gases from the boiler, will be checked for any obstructions or leaks. A blocked or leaking flue can be dangerous, so this step is crucial.
Boiler and heating controls
Next, the engineer will test the boiler’s controls to make sure they are working correctly. This includes checking the thermostat, timer, and any other controls you use to operate your heating system.
Gas pressure and flow
The gas pressure and flow will be checked to ensure the boiler is getting the right amount of fuel. Incorrect gas pressure can affect the efficiency and safety of your boiler.
Combustion chamber
The combustion chamber, where the fuel is burned to generate heat, will be examined. The engineer will ensure it is clean and free from debris, which can affect the boiler’s performance.
Heat exchanger
The heat exchanger, which transfers heat from the gas to the water, will be inspected for signs of corrosion or damage. A faulty heat exchanger can significantly impact the efficiency of your boiler.
Safety devices
All safety devices, such as the pressure relief valve and the high-limit thermostat, will be tested to ensure they are functioning properly. These devices are crucial for the safe operation of your boiler.
Service report
Finally, the engineer will provide a service report detailing the work carried out and any issues identified. This report is important for your records and can be helpful if you need to make a warranty claim.
Does an oil boiler service take longer?
Oil boilers are a bit different from gas boilers, and servicing them can take a little longer. On average, an oil boiler service can take between 45 minutes to 1.5 hours. This is because oil boilers have additional components that need to be checked and maintained.
Oil tank and oil filter
The oil tank and oil filter are two key components that require special attention during an oil boiler service. The engineer will check the oil tank for any signs of leaks or damage and ensure the oil filter is clean and functioning properly.
Oil lines
The oil lines transport oil from the tank to the boiler and will also be inspected for leaks or blockages. Ensuring these lines are in good condition is essential for your oil boiler's safe and efficient operation.
Burner and nozzle
The burner and nozzle, which mix the oil with air and ignite it to create heat, will be checked and cleaned if necessary. A dirty or malfunctioning burner can reduce the efficiency of your boiler and increase your energy bills.
When should I get my boiler serviced?
You should get your boiler serviced annually to keep it running efficiently and to maintain its warranty.
The best time to get your boiler serviced is during the warmer months, ideally in late summer or early autumn. This ensures your boiler is in top condition before the cold winter months set in.
Why should I get an annual boiler service?
Safety: Regular servicing helps prevent dangerous issues like carbon monoxide leaks. Carbon monoxide is a colourless, odourless gas that can be fatal if inhaled in large quantities.
During a service, the engineer will check for any potential leaks and ensure your boiler is operating safely.
Efficiency: A well-maintained boiler runs more efficiently, saving you money on energy bills. Regular servicing helps keep your boiler running at its maximum efficiency, which means it uses less fuel to heat your home.
Longevity: Regular maintenance extends the life of your boiler, avoiding the need for costly replacements.
Boilers are a significant investment, and annual servicing can help you get the most out of your investment by keeping your boiler in good working condition for longer.
Warranty: Many manufacturers require annual servicing to keep the warranty valid. If your boiler is still under warranty, regular servicing is necessary to ensure you can claim any repairs or replacements covered by the warranty.

FAQs about boiler servicing
Do they check radiators on a boiler service?
Typically, standard boiler services focus on the boiler itself and its immediate components rather than the entire heating system, which includes the radiators. The service involves checking the boiler's main functions, safety devices, and efficiency.
However, some engineers might perform a quick visual inspection of the radiators to identify any obvious issues like leaks or cold spots. You might need to book a separate heating system service or power flush for a thorough radiator check and maintenance.
Can you put the heating on before a boiler service?
No, it's generally recommended not to put the heating on just before an annual service. The boiler should be cool when the engineer arrives to ensure safe and accurate inspection and servicing.
If the boiler is hot, it can be dangerous to work on and may also affect the readings and assessments the engineer needs to make. It's best to turn off your heating system a few hours before the scheduled service to allow everything to cool down properly
