Opening a bank account in the UK is like extracting blood from a stone. The ID requirements include some sort of proof that you are living in the UK, utility bill etc. As you will be there for such a short period it is likely that by the time you have opened the account you will have long since left the UK.

I'm not sure on the tax obligations but you could possibley open an account in the Channel Islands with one of the High Street banks and then get the money paid into there. I think they still use regular sort codes like the mainland but obviously they are available to non-residents.
