Since posting that I've seen some expensive Hozelock self-winding options

I'd really like to spend a lot less if I can...

The Hozelock Mini Auto Reel would be ideal for you. It's a smaller
version of the more familiar 20m self-winding Auto Reel and costs
around £45 from Argos and numerous others. But all self-winding hose
reels need to be fixed to a wall for the extra stability the wall
gives.
