5 Signs You Need to Repair your Boiler

Winter is coming! And with it, a lot of “wintery” needs that need to be taken care of. For example, your boiler.

Being the centre of your overall heating system, it’s the last thing you will be wanting faulty when the brutal, cold air of fall seeps through your windows.

To make sure that doesn’t happen, here are 12 major signs that signal towards having your boiler repaired right now!

12 Signs You Need to Repair Your Boiler

1.   It’s not efficient

Is your boiler taking longer than before to heat up the room? Or your energy bills are getting higher without any apparent reason?

Chances are that your boiler is not performing the way it should. That being said, there are multiple reasons you can blame for the condition.

Either it some air trapped inside your radiators or the heat exchanger of the boiler is faulty, or maybe the boiler is just too old to work properly anymore. In any case, have a professional check it for you.

Although it can be fixed in normal case scenarios, a replacement is inevitable if your boiler has gone past its actual lifetime.

2.   Strange noises

Another tell-tale sign of your boiler requiring a repair is strange, gurgling, or hissing noises coming out of it.

The main reason for this is the build-up of lime or sludge inside the heat exchanger. These weird noises are also associated with low efficiency (as mentioned).

If left for long, this lime will keep building up, slowly deteriorating the boiler’s functionality and then ultimately resulting in a complete boiler breakdown.

The best course of action here will be to call a professional and get it fixed without any delays.

3.   CO leakage

Well, it’s quite difficult to tell when your boiler is leaking carbon monoxide. It’s an odourless, colourless, and tasteless gas and is often regarded as “the silent killer” due to its poisonous and flammable properties and often happens when boiler maintenance is not done properly .

Long term exposure to it can be fatal for you and your family. How to know if it’s leaking? Well, see if there are any signs of constant headache, weakness, dizziness, nausea, or shortness of breath in you or your family.

In the worst-case scenario, someone can even get unconscious. Another good indicator is the change in flame colour. See if it’s yellow instead of the clear blue.

If you even have the slightest doubt that this might be the case, don’t wait for a single second and hire a competent boiler repair service to deal with it ASAP.

Also, don’t forget to install a CO smoke alarm to avoid this complication in future.

4.   Boiler frequently shutting down

If your boiler is shutting down frequently, there must be some problem with your thermostat or some problem with the water pressure that is causing the auto-shutoff feature to activate.

It is a safety feature that is supposed to detect the overpressure or heating of the boiler and turn it off to avoid any unpleasant event. Booking a boiler repair service will prevent this from happening.

5.   Operating issues in the boiler

Sometimes when one corner of your house is boiling hot while the other is ice cold, it’s a clear sign that there are some operating issues with your boiler that needs to be taken care of. Otherwise, you will be paying bills to just heat a room. To make sure that doesn’t happen, hiring a boiler repair service is a viable option.


Winters have just come and the demand for boiler services is only going to increase across London.

This means any delay will only push you down the list of the huge number of people who have booked their boilers for repair, resulting in a bunch of tormenting, cold nights.

So just in case you are noticing any of the aforementioned signs, do not wait to call a professional and have it fixed.

How long should a boiler last?

The average lifespan of a boiler lingers around 10-15 years. So if your boiler is older than that, there’s no point in hiring a repair service. You should just go for a repair and that should work perfectly fine.

Is repairing a boiler a viable option?

If your boiler is relatively new and hasn’t passed its lifetime, repairing it will be the most cost-effective and viable solution at your hands.

However, if it has served the past 10-15 years, there’s no point in repairing it. Plus, as the boiler might no longer be in production, the repairs will also be highly expensive.

Is it legal to repair your boiler by yourself?

Yes! In fact, you can do it for others as well as long as you don’t charge them any money. However, if you do, it’s necessary for you to be a registered gas safe engineer. If you aren’t, it’s a totally illegal activity.

Is it worth repairing a 20-year-old boiler?

The straight answer to that would be no. A 20-year old boiler has certainly passed its functional period and should not be wasted any money on. A more wise move here would be to simply change it.
