Boiler repair £150 £350 £300 £700

If you have ever had to call out a plumber or heating engineer to repair your boiler on a freezing cold wintery morning then you will know how costly and time-consuming a process that is, as well as how ecstatic you feel once it is working once again. The need for repairing your boiler can often be avoided by annual maintenance, but everything has its shelf life. There is every chance that your boiler will eventually fail, break down or become faulty.

In most cases your boiler can be repaired, rather than replaced by a Gas Safe-registered plumber or heating engineer. You should always check that anyone repairing your boiler is on the Gas Safe Register, as registration is a legal obligation. This should ensure that whoever does the repair and maintenance work on your boiler is up to date with the latest in boiler technology. Unqualified gas engineers may well be cheap, but an incorrectly-repaired boiler is likely be extremely dangerous. It is always better to pay for the cost of a qualified professional than worry about whether the repair is safe.

Why your boiler may need repairing

Reasons that your boiler may need to be repaired include the fact that it is losing pressure, not firing up properly (especially with an ‘on-demand’ combi boiler) or the timer switch is malfunctioning. The most dangerous fault with a boiler is one where fuel is not burning correctly and the pilot light is burning orange rather than blue, sending carbon monoxide back into your home. Purchasing a simple carbon monoxide detector will help you avoid any such dangers, but a qualified plumber or heating engineer can check and service your boiler to make sure that no such dangers exist.

Ignition problems with your pilot light may be due to mineral or dirt build ups on the ignition mechanism and your plumber should be able to repair this quickly. Problems with the system staying ignited are often down to a simple loss of pressure over time, which is usually quick and simple for your plumber to diagnose and resolve. A good heating engineer will be happy to show you how to remedy simple pressure problems by topping up the pressure via the valves underneath your boiler.

Repairing your boiler rather than replacing it

Boilers are fairly simple in terms of engineering, but parts can go wrong and may need replacing. Even if your boiler develops a complex fault your heating engineer or plumber should be able to diagnose and then repair it. Most boiler repair experts will have replacement pipes, timers or switches on hand, although some more specialist parts may need to be ordered in.

Modern boilers may need circuit boards replacing in order to get hot water and heating on the go again and this can prove expensive in some cases. But even this kind of repair is preferable to replacing the boiler in cost terms. Always remember that boiler failure is often a symptom of a problem elsewhere in the system, such as a leak. Any time taken by your plumber in diagnosing the problem ahead of repairing a boiler or central heating problem is always money well spent and will save you cash in the long run. A good boiler will last you up to 20 years, so it is always advisable to buy a good brand named appliance and have it regularly serviced .
