Can I remove the old wiring?

[#1]

Hello, 

Just signed up for full fibre, with engineer coming to install in a few weeks.

Got old wiring in the house, several ethernet boxes around the place. Can I take these out, are they no longer necessary, like upstairs for instance? House will be decorated by time engineer comes, dont want the old boxes there if I dont need them (video showed them putting new box on inside and outside of house) so are these old ones not needed?

Thanks

Are you sure they are ethernet boxes , or are they telephone sockets ? (if youre not sure post a photo)

Telephone sockets will not be of any use anymore, but ethernet sockets could still be useful.

If you are definitely having Full Fibre installed, then

I, 2  & 5 are telephone sockets and can be removed.

4 is a combined dsl/telephone socket and can be removed

6 is a TV aerial socket and probably should be left

Not sure what 3 is its just a wire

Again not sure what 7 is , its a wire

None are ethernet
