Boiler Servicing Costs 2025 – What Homeowners Should Expect

Boiler servicing is one of those essential jobs homeowners often forget about — until the heating stops working.
In 2025, the cost of a standard boiler service has risen slightly due to higher fuel and parts prices, but staying
on top of annual maintenance is still far cheaper than paying for unexpected breakdowns.
