If you have one of Santander's 123 accounts you also get 1% cashback on the first £1,000 of your monthly mortgage payment (presuming your payment comes out of the 123 account).
So that's a potential £120 yearly cashback.
Note - Product fee means this benefits those with over larger remortgages, otherwise £0 fee, higher %age fixes will be better.
Lock in rate : 4 months in advance.
