How Much Does Boiler Repair Cost in Birmingham?

Boiler on the blink? Don’t struggle without hot water or heating any longer. With the right plumbing service, you can quickly get your boiler up and running again so you won’t need to worry about losing hot water or heat at a critical time.

How much does boiler repair cost?

The cost of boiler repairs will nearly always depend on the cause. Some repairs are down to boiler configuration and can be fixed by addressing these problems, while others may be caused by worn or broken parts.

There are three parts to the boiler repair cost that you should anticipate:

The callout fee. This covers the cost of your chosen plumber visiting your property and diagnosing the issue. From there, they’ll be able to give you a quote to fix the problem. They might also recommend a full boiler replacement if it will cost more to repair than to replace.

The labour fee. This is the time spent working on the boiler. Plumbers will typically charge by the hour, so the longer it takes to fix the boiler, the more it will cost. For larger projects, your plumber might recommend a day rate.

The parts fee. If your boiler needs new parts or components, this will also be included in the quote. To give you an idea of average costs, a new heat exchanger could cost between £400 and £600, while a gas valve could cost between £180 to £260.

Don’t forget that you’ll also need to add VAT on top of the quote, if it isn’t already included. You might also pay a premium rate for work that takes place out of hours, and emergency callouts.

What is the most expensive boiler repair?

Boiler repairs costs will often depend on the age, type and brand of your boiler. The less common the boiler, the more expensive the parts will be.

You may also need a specialist engineer capable of working on your particular boiler – this is true for oil and commercial boilers, which can only be repaired by OFTEC-registered engineers. For all other boilers, you need a Gas Safe Registered engineer.

The most expensive repair on a boiler tends to be the main heat exchanger, which can run up costs of around £400 to £1,200, depending on the brand of boiler. Other expensive repairs include replacing the printed circuit board, which can cost around £300 to £500, and motorised valves, which can cost around £300 to £450.

When should I replace rather than repair?

If your boiler is between 10 and 15 years old, and the cost of the repair is likely to exceed £500, then it might be time to consider a full replacement. A new boiler would cost between £1,950 and £2,800, and this would be much more efficient, reliable, and it would come with a fresh warranty.

Once your boiler reaches the 10 year mark, you can expect breakdowns to be more frequent, so it often makes sense to invest in a new boiler before you’ve spent the cost equivalent on repairing an old one.

The difference between a faulty boiler and a dangerous boiler
