Yes, servicing a boiler is generally considered to be a cost-effective practice. There are several reasons why regular boiler servicing can save you money in the long run:

1. Improved Efficiency: A well-serviced boiler will operate more efficiently, which means it will use less energy to heat your home or provide hot water. This translates into lower energy bills, which can help to offset the cost of the service.
2. Fewer Breakdowns: Regular servicing can help to identify and fix minor issues before they turn into major problems. This means you’re less likely to experience a breakdown, which can be costly to repair, especially if it happens at an inconvenient time.
3. Longer Lifespan: Regular servicing can help to extend the lifespan of your boiler, which means you won’t have to replace it as soon. This can save you thousands of dollars in replacement costs.
4. Warranty Requirements: Some boiler manufacturers require regular servicing as a condition of the warranty. If you fail to service your boiler as required, you may void the warranty, which can be costly if you experience any issues with your boiler.
5. Safety: A well-serviced boiler is less likely to pose a safety risk, such as carbon monoxide poisoning. Regular servicing can help to identify and fix any safety issues before they become a danger to you and your family.

While the cost of a boiler service may vary depending on the type of boiler you have and where you live, it is generally a small price to pay for the peace of mind that comes with knowing that your boiler is working safely and efficiently. Most experts recommend having your boiler serviced annually to ensure that it continues to operate at its best. In conclusion, servicing a boiler is a cost-effective practice that can save you money in the long run by improving efficiency, preventing breakdowns, and extending the lifespan of your boiler.
