It's hard to say, it won't be anywhere near as expensive as moving a mux/node cabinet. In theory I would imagine it would be your responsibility to cover costs as when originally installed it would have been in a decent location. But seeing as it's in your back garden and that will make any maintenance or outages very difficult to handle, so vm may want to move it. I'm sure there are some planners on here who may be able to offer better advice as to where to go with it.
