Wayleave Authorization

Before you agree to this, check to see if there is an alternative route for the cable that doesn't involve your drive. 

The contractors that VM use to lay the cables will always use the quickest, cheapest route. If for instance your drive will save them digging a trench in the pavement they will always go for that.

Bear in mind that the wayleave is permanent and will remain when you sell the house. It will likely be worded openly to let them do further work if they wish. 

You won't know who will do the digging. Once VM instruct a contractor, even they will not know who will be sent. 

If the three houses all have legal access rights to the drive, VM will need wayleaves from all three. Have you discussed with the third house? 

In addition to the info from jpeg1, we have seen past topics on here where some carefully laid plans for cables have been agreed with a VM person in advance only for the cabling sub-contractor to turn up and do something totally different. The sub-contractors can turn up unannounced at any time so you may not be at home to supervise what they get up to.

if VM is still using this, or similar, you should read all the T&Cs carefully as some of them are pretty onerous and not to the advantage of a third party neighbour.

Understandable that you would want to keep on good terms with your neighbour but, once VM has the signed agreement, you will be at the whim of whatever VM or its sub-contractors choose to do.
