Boiler repairs in London

This will depend on the type of boiler you have and the extent of the problem. Some faults can be fixed relatively quickly and cheaply, while others will require far more extensive work. Your engineer will be able to properly diagnose the issue and provide you with an estimate of how much the repairs will cost. At BOXT, we charge a flat callout fee of £89 for a one-hour consultation visit, and if we can fix the problem there and then with no additional parts, you won’t pay any more! If any extras or more time is needed, we won’t charge for anything else without discussing it with you first.

It is illegal for anyone without the necessary accreditations to do any work on a gas boiler, whether that’s installing or repairing it. We don’t recommend that you get a handyperson to repair any type of boiler, electric or gas, as they won’t have the necessary training to do the job to a high standard.

You can carry out routine maintenance checks yourself, such as checking the system pressure and bleeding radiators, but any in-depth maintenance or repairs must be carried out by a trained and qualified professional.

Deciding whether to repair a boiler depends on several factors: the age of the boiler, the cost of repairs, and the frequency of breakdowns. If the boiler is relatively new (less than 10 years old) and the repair cost is minor, it is usually worth fixing. Regular maintenance can extend the boiler's lifespan, making repairs a viable option. However, if the boiler is older than 15 years, frequently breaks down, or the repair cost is over half the price of a new unit, getting a replacement might be more cost-effective.
