Electrical Question

Is it my fan or the wiring?

When i switch on my bathroom light the extrator fan starts running. after a few seconds the fan starts to turn on and off, when i turn the light off the fan starts running normally and switches off automatically on the timer. is this a problem with the wiring or the fan?

From what you describe, its sounds like its a problem with the timer circuit board inside the fan. Its very common for these to play up and in most cases are non-repairable.

As replacing a fan in a bathroom (even a like for like fan) comes under part P of the building regulations, you need a registered installer to carry out the work so that the work can be registered with building control on completion.

Post a job on this website to get a range of quotes. A good quality UK made fan (e.g. Vent Axia or xpelair) would cost around £35 - £40 if its an axial fan, and perhaps as much as £70 if its a centrifugal type.
