Best bank to open joint account with?

Hi folks, myself and my partner are looking to open a joint account to manage bills and save for a deposit for a house. We are looking at a current account and savings account for the deposit, hoping to buy within the next 18 months. We have 7k ready to put into the deposit account.

​

I have looked at each banks websites and read up but I am hoping that someone who is more clued in with these things may be able to offer some advice.

​

Many thanks.
