I don't remember seeing anything about this before, and maybe it's just our borough, but my church received a letter on 1st April announcing that the system for registering marriages is changing: the Borough will be legally responsible for registering marriages after the above date, and we will no longer be able to issue certificates. We have to surrender all the stationery and the registers and the relevant people have to do an online training course on the new system.
Fortunately, I photographed the registers some time ago so have only to catch up with the last few pages. Any church archivists out there should be warned that they're about to lose their registers. Hopefully, they'll be put in the borough archives, but they're not very accessible at the best of times. I await with interest how the register office will cope with emergency requests for copy certificates to be faxed to remote parts of the world for some legal purpose a couple of hours hence on a weekend.
I also wonder how the gravitas of the "signing of the register" part of the service will be affected by the happy couple et al crowding around a laptop or phone app rather than an historic tome. The minister, however, is looking forward to no longer being covered in indelible ink.
