With the cold snap gone it's worth evaluating what went well and what didn't.
I like to also think what would happen if the power got switched off and water pipes froze? Remember that help often takes a long time to come from some service providers (they've been "fixing" a leaking gas main down our road for over a year now...). Maybe would be left without heat, as it is many are worried about the cost of their heating and having it on less as a result.
