Been away for a few days and just noticed on our return that the fridge
has started acting almost like a freezer. The back panel has maybe an
1/8th to a 1/4 inch of frost on it and things such as two bottles of
lemonade that were very lightly in contact with the panel have frozen
solid.

It's a Hitachi Larder Fridge (Model R11 LCS) and, when we bought it about
10 years ago, we set the temperature dial to "6" and it's never been moved
from that setting at all, ever.

Any idea what's wrong and if it's diy-fixable?

If it's the thermostat, and you know how to remove it and fit a new one,
then yes. But if the dial is the usual zero to 6 then setting it on 6 is
normally too cold and results in freezing. Usually a setting of 3 or 4 is
OK. If it has been set at 6 for 10 years, and 6 is the maximum value, then
it's strange that this problem hasn't occurred before now.
