Nicked a copper pipe - what to do?

Do not know if it even needs a repair but if you are wanting to do something.
Clean the pipe with a alcohol wipe then put a few layers of  Sally Hansen Hard as Nails transparent on pipe.

I always kept a bottle in van ashtray incase we got a stone chip, give windscreen a clean and a couple of layers of that helps stop a chip turning into a crack.
Windscreens will go through a lot more stressing than those pipes will.

All these suggestions sound like bodges. Drain system, cut pipe, solder in correct sized Yorkshire joiner.

Whilst you're at it, notch out that joist a tiny bit more and wrap a bit of felt around both pipes to stop any creaking noises as they heat and cool.

I agree.
All those other suggestions are bodge jobs.
Do it properly or you could have a massive flood on your hands sometime in the future.
Not worth the risk.

I don't understand why there are so many "bodge it" suggestions. That pipe is going to be covered up soon with floorboards then carpet or other material. I'd want to be absolutely sure it wasn't ever going to leak because the effect of that will be a lot more time and money consuming than doing it right the first time.

That's the very reason why I'd probably go with the 'bodge'.

Cutting the pipe, cleaning it up, and installing a repair fitting means the pipe will inevitably be moved around and stressed a bit.  I don't know what the state of the pipe is under the remaining bit of floorboard, whether the pipe is fixed to anything, and what fittings (if any) the pipe attaches to.

In jiggling the pipe around to cut it, clean it, and join/repair it, I don't know what (latent) damage might be done to the pipe and joints I can't see.  I could cut the next piece of floorboard out to have full access, but that risks doing damage to something else, plus the relative difficulty in repairing the floorboard securely.

Plus, any kind of joint/fitting is going to have at least two potential points of failure, rather than the existing single point.

My calculation would be that carefully adding some solder to the pipe insitu carries less long-term risk than disturbing the pipe(s) further to do a full repair.  Perhaps that comes from my natural reluctance to disturb things which are working OK, just to do the job 'properly'.

If the pipe had been pierced and was leaking then I might tend towards a more substantial repair, but as the pipe does appear to be just 'nicked' and is holding the pressure in its damaged state, then if it were my decision then I'd go for the least invasive solution.

Adding a little solder to the pipe is no more likely (IMV) to cause a massive flood in the future than jiggling the pipes around trying to get a perfect repair.

Give it back?

Looking at the picture, it doesn’t look like anything needs doing. The damage is very minimal and not likely to leak, generally the pipe thickness is a lot more and this seems more of a scuff

Have you made a decision, Greenie?
Could you DIY a solution? 
What room is on the other side of that wall - could you lift a 'board there?
Possibly a plumber with a high temp focussed flame torch could apply a blob of solder without draining, I don't know. In theory, tho', not. So it looks as tho' any repair will need a partial drain down.

Drain the system and just flood the nicked piece of pipe  with solder, job done
