Looks quite strange. They ask for 10 yrs of council tax and utilities bill. How is one supposed to get 10 years of those. Senior members please comment.
ONLY if you CAN'T
supply your previous passports then you can send the council tax bills or other bills to prove you have been in UK those years,
if you have
all your passports which covers all ten years then you dnt have to send the bills.
this is below from set(LR) form
All the passports you have held during this time.
If you cannot provide them all, you must
provide the passports you have together with any Home Office letter(s) or other document(s)
granting you leave to enter and/or remain in the UK. You should also provide documents of the
type listed below to show that you were continuously resident in the UK during any periods for
which you are unable to provide a passport.
