The cost of a boiler repair can vary depending on the extent of the fault or damage. You can expect to pay anything from £65 if no parts are required. For other minor repairs such as a replacement fan, gas valve or printed circuit board, the price could range between £150 - 400.
It is very difficult to be more precise than this because the price depends on a number of variables, including the type and age of your boiler and the cause of the fault.
Older boilers, for example, can be expensive and timely to repair due to the reduced supply and higher cost of parts.
We would recommend if your boiler is over 10 years old and the repair costs exceed £300, a replacement boiler
may be a better option.
