cold weather and frozen pipe

[Newby2]

Hi
I am currently on holiday abroad. Unfortunately I shut down the central heating before I left. Now we have the coldest March on record, I just checked the lowest temperature of my home area is around -1 or -2C (for 2 or 3 hours during the night). I wonder if this is cold enough to lead to frozen pipes or water tanks (e.g. in the loft)?

thanks in advance for any reply.

Shouldn't be a problem providing they are well insulated.
