But I was interested to see that some plain fish in Sainsburys has been frozen and defrosted and then you can also then freeze it home again. I thought that wasnt 'the done thing'?

Provided it's been defrosted under refrigerated conditions it's fine and then refrozen within the space of a few days.

Can’t see where it says it can be refrozen -but there is prob no air in it once packaged so could be possible

In the storage tab and also safety tab

I ignore BBE & use by - with the exception of fish.

But this clearly states it can be re-frozen with certain conditions, so I'd do it if necessary.
