Hi,
Yes, keeping it in sterling is the best option for now. The Euro is facing a big test at the moment, and there are signs that the market is becoming nervous about it. Simply put, Europe has too many different economies and some suffer more than others in the bad times. A perfect example is Spain. They need lower rates than 2%, but countries like Germany don't need it lower than 2% (at the moment).
Confidence is a funny thing. Rather than the GBP-Euro rate getting worse after the BOE decision, it actually got better. This is because the ECB didn't make a move, which suggests to people that they aren't willing to do what is needed.
In regards to your savings question, look at some of the safer banks. HSBC and Barclays have fairly little exposure to bad debt, but that could change. I would say those two are the safest banks in the UK at the moment.
