FAQs

how much does a boiler repair cost?

How Much Does A Boiler Repair Cost?

An annual service for your boiler might not seem important and may be easy to postpone to another day, but when it happens to breakdown due to lack of adequate attention, this can be quite painful and also costly.

Before you start thinking about the cost of repairing your boiler, the first thing you’ll need to confirm is whether or not your boiler is still covered by the manufacturer’s warranty. You’d be amazed some warranties can last for as long as 12 years, if yours is still on then you can save yourself a huge amount of of money on your boiler repair. As a result, it’s always crucial to keep the details of your warranty somewhere safe, so you can read them from time to time. You never can tell when the rainy day will come!

Most boiler warranties will require your to get your boiler serviced on an annual basis by a licensed and qualified technician. The cost of an annual boiler service is affected by the time of the year you wish to get it done. When boilers are less useful during the summer months, an annual service is usually relatively cheap when compared to the cold months. Around this period, a boiler service will normally cost within the range of £100 to £150, however for a more accurate quote it’s advisable to contact a couple of professionals and compare their quotes.

The cost of getting a boiler repaired will be affected by a couple of factors including your boiler’s make, the age of the boiler as well as your location and how urgent you need it done. If you have a dead boiler, the cost will typically range from £96 to £348 and a boiler displaying a fault code will cost within the range of £90 to £275. Generally, repairing a boiler will cost within the range of £90 to £400 based on the several factors stated above.

how often to service boiler?

How Often To Service Boiler?

A boiler is a vital part of any home especially if you’re in the UK. Not only does provide your entire household with hot water and keep them warm but also adds a good value to your property. Boiler repairs and replacement are both super expensive and stressful, so in order to avoid all these worries, it’s better to have your boiler serviced on a regular basis for your own peace of mind. When you call in a reliable heating engineer, it can immensely raise your boiler’s efficiency while also saving you from more expensive issues down the road.

So if you haven’t had your boiler serviced for quite some time, moved into a new house and not aware the last time your boiler was serviced or perhaps you’re just wondering how often a boiler should be serviced, then you’ve come to the right place! The short and simple answer to this question is a boiler should should be serviced once in a year, and most preferably during the summer months. However, there are a wide range of factors that comes into play so it’s always advisable to check with your manufacturer before you proceed.

According to the law, you’re required to have your boiler services on an annual basis. Failure to do so can render your boiler or home warranty void. Therefore, it’s very crucial to take down the last time your boiler was serviced and also set a reminder to book your next appointment when the time closes in.

If you happen to own an electric boiler you may not need an annual servicing. But you may still be required to perform it annually by your insurance provider.

Can I repair my own boiler?

No. You must never repair your own boiler – only a Gas Safe-registered engineer can do any work on your boiler. You can do simple DIY tasks to repressurise your boiler or stop a leak, but if you have to remove the outer casing of the boiler or touch the flue then you must get a qualified boiler engineer to take a look at your central heating system.

How to repair a boiler leak?

If your boiler is leaking, there are some checks that you can do yourself. However, you should never attempt to repair your boiler yourself – only a Gas Safe-registered engineer should conduct repairs.

There are 3 main reasons why your boiler might be leaking: there’s a pressure valve fault, a temperature valve leak or corrosion in the system. An engineer will be able to spot the problem quickly, but in the meantime there are a few things you can do:

Check the pipe fittings

If your boiler is leaking water around the pipe fittings, it could be an installation fault and you should get in touch with the engineer that fitted it. You can check the pipe fittings by drying the area then waiting to see if the water appears again. If it does, you may be able to do a ¼ turn of the pipe to stop it. However, you should still call the engineer that installed it to ask them to check the PTFE tape on the inside.

Inspect the seals

Over time, the rubber seals on a boiler can start to perish, so if you have an old boiler this could be the source of your leak. If you have a new boiler, it could be caused by your boiler running over pressure.

Heat exchanger corrosion

Unfortunately, if a boiler engineer discovers that the boiler is leaking water from the heat exchanger, this is the end of the road for your system. The heat exchanger is the most expensive part of your boiler, so it makes more financial sense to replace your boiler with a newer, more efficient model rather than try to replace it.
