Over the last year, we’ve posted over 100 heating articles, many of which relate to boiler fault finding and central heating problems.
I’ve spent a while trying to organise 40 of them in a way that helps readers quickly and easy find the article they need, to diagnose their boiler fault.
We’ll be using this page as our central heating and boiler fault finding resource guide, and will be adding to it over time.
So, feel free to bookmark it and come back to it when you’re stuck.
To begin, we’ve created a generic guide to boiler problems here. It’s a good starting point.
That’s going to be useful if you have no idea what’s causing the problem. Once you’ve used that boiler problem guide to figure out what could be causing the issue, come back to this page and you’ll find the specific guide listed below
