Being pedantic, is it certain they intend to install equipment on your land
or simply near it?
I suspect the devil is in the detail.
For example.
The phone lines etc in our road are on poles. I suspect they were installed
long before many of the houses were built. Certainly before ours by
decades. Open Reach have made various changes - fibre etc- all without any
consultation ( not that I object). The poles run down the edge of the road,
possibly in an area which was originally not in peoples gardens, but over
the years fences have moved etc. Some years back ( 20?) a previous
neighbour who had a pole in an inconvenient place, requested it to be
moved. This was done. I don’t know who paid. (We don’t have one, although
it is now on our boundary, not that we mind.)
Obviously, there are various wires / fibre optic cables to the properties
which go from the poles. I’ve never heard of anyone objecting.
Oddly, even though the power lines are overhead, the suppliers to the
houses aren’t, at least in most cases.
Nor are there any service boxes in the road. Or, if there are, they are
VERY well hidden.
