Mike Barnes brought next idea :
Possibly DIY, possibly not. :-)

There's a BT telegraph pole adjacent to my house. It is supported by a stay
which is anchored on my land. The anchor is in the middle of an area that I
want to use for wheelie bins.

I'd like the anchor moved back away from the road, as close as possible to
the wall, to make way for the wheelie bin park. The ground level would be
dropped a few inches as well.

The pole was replaced about 15 years ago. BT didn't ask us whether they could
put that stay there, they just went and did it. They could be forgiven for
assuming that that land was part of the public highway, but it isn't. They
aren't making any wayleave payments. We didn't take much notice in the past
because this was just a piece of waste land as far we were concerned, but now
we've got a sizeable collection of wheelie bins it's suddenly become useful.

So, does anyone know what's underneath there? Is there any experience or
knowledge in the group concerning the procedure for getting such an anchor
moved?

This is the type of thing BT use http://tinyurl.com/ol2m8uy but BT ones
are about 5ft long - so no, they won't move it over a few inches for
you, or if they do, be prepared for a *very* big bill!
