In my experience, BT will come out, find nothing, then charge you £120 plus VAT for the privilege.

Best of luck, hope you get it sorted.

Do the testing from the master socket and if the problem still exists, then it is likely a fault on the outside, so you should not be billed. If the problem is on the inside wiring, you're likely to be charged.

I do have sky and the boxes are all filtered. Besides, the sky boxes have been in for 6 months and the problem only started on 12 April.

The isp is investigating. I think its a BT fault myself. Thanks for the comments.
