Can you fix a fault on my line if it’s proved in the BT network?

No sadly not. Although I spent nearly 10 years working on the network climbing hundreds of poles and working in numerous underground boxes, I am not authorised to now work there. This would be effectively trespassing and could lead to legal action against me by BT. If I visit your premises and prove the fault into the BT network then you will have to contact your service provider to raise a report. I am more than happy to assist with this, as quite often customers get highly frustrated when negotiating the multitude of options when speaking to call centres.
