Hi
a
I am just in the process of doing exactly the same.
I bank with Santander in London and the app is giving me better rates than anywhere or any of the exchange companies.
yesterday it was 1 1653 which compared to Currencies direct 1.131 you can see the difference.
today it is currently 1.1598 so down a little on yesterday, but anything above 1.15 is good at present I think.
I am trying to get 1/2 my money there before Brexit and see what the rate does after it’s done, I have 2 years to build so if the rate does drop it’s no real worry.
only downside is I can only send 10k sterling limit per day and I have had to email Sabadell explaining the reasons as they thought it looked dodgy!
I am sure your bank will have something similar.
