Boiler Repairs

We’ve listed some key signs below that your boiler may need replaced. However, with regular servicing, you can make your existing boiler last longer, our engineers can discuss options with you to find the best solution that suits you.

Recurrent breakdowns
If you need to have your boiler repaired more than once a year, it’s worth considering whether the sum of repairs and callouts is greater than the cost of a new boiler. Regular servicing will help your boiler to run more reliably all year, so a replacement is only needed if your boiler still struggles afterwards.

Rising bills with no obvious explanation
You’ve probably heard about the “efficiency rating” of boilers, but you may not know what it means for your household bills. Simply put, a less efficient boiler costs you more money to run. Modern boilers are A-rated and operate at more than 90% efficiency, while G-rated models run at 70% or less. While upgrading from a G to an A-rated boiler could save you around £200 a year, and may be better for the environment.

Noisy boiler or radiators
Central heating systems make all sorts of sounds, most of which are completely harmless. But it’s worth noting any changes in noise type and volume. Tapping sounds on pipes or radiators could be a sign of “sludge” build-up in your system. This is easy to fix with a Powerflush. But if you hear humming, vibrating or banging, a bigger fault may exist within the boiler or central heating system. Get in touch if you’re hearing any unusual boiler or central heating noises.

The blue flame is now yellow
Your boiler flame should burn bright blue. If it’s changed to a yellow or orange colour, your boiler needs an immediate attention. They’ll be able to tell you how serious the problem is, and the best way to resolve it. Please do not ignore this.

Your boiler smells odd when it’s on
If you smell a sulphurous odour when you use your boiler, there’s probably a gas leak. Immediately turn off the boiler and call the emergency gas line on 0800 111 999. Then get in touch with us. Do this if you ever detect any unusual odours emitting from your boiler. Learn more in our safety guide. In this situation, your boiler may well need replacing.

Leaking boiler
Your boiler shouldn’t ever leak water. If it does, an internal component, may have broken. Leaving a problem such as this unfixed could lead to an electrical short-circuit, and even structural damage to your home. So switch your boiler off and get in touch with us to arrange an inspection. Hopefully, it’ll be possible to restore it to full working order, without the need to replace it.

Replacement parts are difficult to find
It’s sometimes difficult to find spare parts when a repair is needed for older boilers. This doesn’t always mean that you need a new boiler, but it does mean that some careful research on the cost and availability of spares is worth doing.

If it’s very expensive to replace obsolete parts, consider how often you need to do this. A real workhorse of an old boiler might hardly ever have issues, in which case, it’s probably worth repairing. If we need to scour the internet for new parts on a regular basis, the mounting cost of repairs could mean it’s more economical for you to replace the boiler instead.

It’s not working like it used to
Despite its yearly service, at some point your boiler might stop doing what you need it to do. If your radiators are taking a lot longer to warm up than they used to, or you’re having to continually adjust your boiler’s pressure, it could be time for a new one. Before forking out, however, it’s worth checking that there isn’t a build-up or blockage in your system preventing it from working properly. We will be able to take a look at it and determine whether it’s a minor issue or your boiler is beyond repair.
