Do you have a source for this? It sounds a bit hard to believe. If the police believe that evidence was/is at risk of being destroyed (as you are implying), they could get an emergency search warrant immediately, even outside normal court hours. In the U.S., there are magistrate (warrant) judges on call overnight for exactly this type of situation; I imagine a similar system exists in the UK.

Yes, I seen the lady in charge of the regulator (not police) on Channel 4 news (here in UK), stating that she will likely be in on Wed and they cant walk in right now.
