Without doing into depth reasoning why simply you should contact Openreach with any concerns of workmanship quality.

I suspect that its not where the incoming line terminates, and it was a Openreach sub-contractor who did it.
Very poor job.
are you a BT broadband customer or with another ISP?
as you are not a customer of openreach you need to complain about the installation to your ISP
I agree that is very poor, unless the fitter was given instructions to use that position in the wall fitting.
That Openreach box appears to only be for telephone, it would be normal to have a faceplate with both a socket for telephone and an RJ45 type one for the broadband. As Keith says, is that the only socket, or is there another one with a faceplate with the two sockets elsewhere?
It looks as though there is a single Euromod space in the wall fitting, so if that is the case and this is not the main supply the you can fit your own faceplate module instead (they only cost a quid or two). If that is the main supply, then you could still supply a module but should get Openreach to fit it as I'm sure they will not supply the Euromod type only their own. If you supply a module it needs to be the right type, master for the first fitting, or slave for the others. You should find out the make of your wall fitting first and determine whether it is a Euromod fitting or a propriety one.
They were when it was installed, but that was a few years ago and we’ve since changed providers. As I mentioned at the time we didn’t know what to do.
then you need to contact your current provider and get openreach visit as nothing BT can do as not customer
