thanks for that. ok so ill get 6 months from old place and 1 from new.
so im thinking mail then would be
December 2017
june 2018
december 2018
june 2019
december 2019
joint mail for each of those times from: water bill, council tax for each year, bank statements, electric?
I also have our leases from may 2017, may 2018, may 2019 and November 2019 )
is that right. or should I be looking for more sources?
