But there was a drop-wire there. I think he was just being unreasonable. He should have at the worst put a small junction box there and run a wire round the room. Was there a box of some sort where the line entered? I can't imagine a bare wire sticking out of the wall.
Unless!
Was he also installing the FTTC or was that a second engineer? If so he could have been described as "working to rule" or if being generous about him, "misunderstanding the rule".
If there had been a master socket at the entry point an FTTC installer as opposed to a pure line installer should not move it, because of the degrading effect on the FTTC. He can fit it there and install a Home Wiring Solution", (often called a Data Extension Kit on these forums because that's what Openreach originally called them).
That would have given you a modem socket using higher grade cable than phone wire, at the place you wanted. But it needed to be ordered by Plusnet and they don't do that by default, it has to be requested by the customer telling them they don't want the modem where the master socket is. It's free, but the engineer can only (legitimately) fit it if it has been ordered. Unfortunately it isn't free as a retro-fit.
Unless you can get Plusnet to raise a complaint to BT Wholesale >> Openreach to sort it for free, your cheapest solution sounds like a spur electricity supply running round the skirting board off the socket you are using to a socket near the master socket.
The proper solution is to install what the engineer could have done, in effect a Home Wiring Solution. If you get nowhere with Plusnet for free, come back to here and ask for more detail on what you need to do. Basically you or an electrician installs an extension where you want it, with a CAT5 solid core cable connecting it to a special connector inside the master. Which you are allowed to do.
For now, a photo uploaded somewhere showing us your master socket would be useful. If it is the latest type the instructions may be just a fraction different so we need to see which type it is.
Is the problem more the lack of a power socket near the master then the modem would be fine there, or is it that you actually want the modem where the power socket is? The preferred location for the modem has to be the first decision, bearing in mind the nearer that is to the entry point the better the speed. The importance of that depends on what speed it is connecting at now.
Could you tell us please? The slower it is now the more important it is to have the modem at the entry point. At a full 79999kbps it matters far less as you may have spare capacity capped by Openreach. Also at high speeds you will not be bothered even if you do lose a bit.
Edit: Typo correction, the last question mark was missing so it read like garbage.
