It’s one of the first questions every London homeowner asks once they have decided to replace their boiler: will you have to rip out the radiators and pipework too, or can they stay exactly as they are? It’s a fair worry. Nobody wants a “simple boiler swap” turning into weeks of disruption and an unexpectedly large … Read more
Type “Worcester boiler not working” into Google at 7am on a freezing Tuesday and you’ll get thousands of results, most of them generic. This one isn’t. It’s built around the actual questions people ask us on the phone every week, in the order they usually ask them: what’s wrong, is it serious, what will it … Read more
If you’ve ever knelt in front of the boiler, torch on your phone, squinting at three letters and a number you’ve never seen before, you’ll know the feeling. Half the time you type it into Google, half the time you just press reset and hope. Fair enough. Nobody grows up learning what “EA 227” means. … Read more
If you’ve topped up your boiler pressure two, three, even five times this week and it keeps sliding back down, you’re not doing anything wrong. Your boiler is telling you something is actually broken. Repressurising a boiler is meant to be a once-in-a-while job, not a daily ritual. When it becomes a daily ritual, the … Read more
Quick answer: A boiler that hums or clicks quietly when it fires up is usually fine. A boiler that bangs, kettles, gurgles loudly, whistles, or vibrates against the wall is telling you something is wrong before you even switch the heating properly for winter.

A single … Read more
If you live in London and need a new boiler, you may have come across headlines warning that gas boilers are being banned. That can make a straightforward boiler replacement seem much more complicated than it needs to be. So here is the important part first: There is currently no blanket UK ban preventing an … Read more
Quick answer: If your boiler has sat untouched since spring and now trips out, bangs, or refuses to fire the first time you turn the heating on this autumn, the cause is rarely the cold itself. It’s usually a pump that’s stiffened slightly from months of inactivity, an ignition or PCB fault that damp storage … Read more
Quick Answer If you’re short on time: a Stoke Newington homeowner’s 14-year-old combi had been banging when the heating kicked in, losing pressure every couple of days, and throwing a fault code that kept clearing itself. That combination pointed to a scaled-up heat exchanger and a dying expansion vessel, not something worth patching again. We … Read more
Quick answer: Hard water is not usually the direct reason a Vaillant boiler loses pressure. If your boiler pressure keeps dropping, the more likely explanation is water escaping from the heating system, a pressure related component fault, or another problem affecting the sealed system.
