On a few occasions recently, I have heard a strange noise from my electric meter cupboard.
It is a loud buzzing. It sounds similar to the noise of minimotor bikes passing by outside, which I thought it was at first.
When it happens, it lasts for several minutes and has brief pauses.

I reasoned that this was not my unique experience, so websearched and learned that it is due to a faulty circuit breaker.

I am due to have a Hyndburn Homes electrcian working on my shower install within weeks and intend to mention it to him.

Meanwhile I ask here -
Is this a problem that I should report immediately?
Is there a risk of an electrical fire?
