FAQs

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 Long Does A Boiler Service Take?

Servicing of your boiler is a very crucial activity which does not only help in keeping your heating system in a top condition, but also assists in ensuring the safety of both you and your loved ones. If you carry out a regular boiler service you’ll be able to identify any possible fault your boiler may have on time before it leads to a more serious issue or even a boiler breakdown. As a result, you’ll be able to save yourself some time and money, but more importantly will save you from any dangerous risk that may result from gas leak in a boiler. The best time for a boiler service is in the summer when you’d probably would not really need the system, so you can take advantage of that as well as the possible lower boiler servicing cost during this period.

Before we look into the amount of time a boiler service should take, let’s first consider what should be done during a boiler service.

✓ Visual inspection. This is a check carried out by the heating engineer to ensure your boiler still meet the existing standards and requirements while also looking for any faults.

✓ Removal of boiler casing. There’s the need to ensure everything is working just fine and also to clean the boiler’s interior. These inspections should include the burner, heat exchanger, main injector and spark probe.

✓ Flue check. This involves making sure that there’s no form of obstructions in the flue terminals as also to ensure that the flue is well installed.

✓ Gas pressure check. This involves making sure that the boiler working with the appropriate pressure.

✓ Boiler fired up. This involves checking for any operating issues.

Generally, a boiler service should be completed within 30 minutes, however this time may vary largely depending on the brand and model.

how much is a boiler service?

How Much Is A Boiler Service?

A broken boiler can be a huge pain and even more so if it occurs during the winter months. A cold house and cold shower is not a situation to be handled with levity especially when there are older people or more vulnerable members in the house. To ensure your boiler keeps functioning the way it should for a lengthy period of time, it’s crucial to ensure that you have your boiler serviced on a yearly basis. But while the summer or warmer months happen to be the most cost effective time to have the boiler servicing done, doing it during the depths of winter can go a long way to ensure that you and your loved ones get through the cold without any unwanted occurrence or boiler issues.

Generally, to have your boiler serviced will cost anything within the range of £80 to about £120, but at times, this can even be more depending on a plethora of factors. The servicing cost will be based on the particular company you choose, the type of boiler you possess, as well as your location in the UK. For instance, if you happen to live in London where demands are higher than the other regions, then you’ll most likely have to pay more money to have your boiler serviced than other homeowners facing similar issues but staying in the other lower demand regions.

Asides from hiring a professional to service your boiler on an annual basis, you should also try to help maintain its efficiency and health in between those services. This will not be a substitute to the regular servicing or even make the servicing a lot simpler, but will surely help keep it at a maximum efficiency while also keeping the cost of your heating bills down.

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.
