No. Turns out it was the cistern. Haven't got round to getting a plumber yet. The bloody thing keeps waking me up in the middle of the night.

Don't know
I'd offer to pop over and have a look but I'm busy the next three weekends.

If it's not pissing water out of the overflow it's not serious.

A quick fix might be giving the elbow joint off the handle a blast with WD40.

I wasn't expecting you to come and fix it : )
I'll get someone in.

Don't waste your money
There's not much that can go wrong with a cistern.

I can't quite understand why it's doing what it's doing unless it's not filling properly until the water pressure rises.

Take the lid off, give it a few flushes and see if the mechanism works smoothly.

I think it might be filling a bit too much and that might cause it.
If I turn the tap on for a short while the noise goes.

So the ballcock isn't sitting right.
Again, WD40 is your friend.

Turn the main stopcock off, flush the bog and give all the moveable joints a good blast.

Give it 30 minutes, turn the stopcock on again and see what happens.

I'll try that this weekend.
I can get some WD40 from work.

Thanks.
