Any advice on this would be massively appreciated

I get UC LCWRA and get HE , I’m thinking of leaving my current flat, I’ve found somewhere else but there are 3 days between current tenancy ending and new one starting. I would probably have to store my things at a friends and sleep on the floor for these 3 days . Does this affect change of circumstances on UC, would they just deduct the few days from UC HE?

I can’t find anything on the web about this at all .

Thanks for any comments
