well if they install the line and give you some deal on their subscription fee in return for using your garden then the assumption is that they are being given access to the line whenever they need to update it etc. Can't imagine they'd be too excited about removing it and finding some other route for the cables once the project is completed. I would say there should be a legal document to back up the terms of access and other expectations anyway.
Personally I wouldn't want any additional utilities running through my property. What happens if you accidentally cut the wire when trimming the hedge...... Just sounds like extra hassle
