What you need for ILR is very similar to FLR. So take your own checklist and assuming the way you are meeting each of the requirements hasn't changed, all you need to do is add the life in the UK test pass and spread your items of correspondence out over 2.5 years instead of 2 years. And they are also asking for a council tax bill which they may not have done when you last applied.
There is the bonus of no IHS to pay.
If you want to pop your list here, we can check it over for you.
Thank you all! I figured it was similar to FLR, but it is always good to get confirmation. Here is what I have so far for my checklist... I am hopeless at the timeline for providing post, so if it is incorrect, if anyone could help, I would appreciate it. I have post from nearly every month for the past 2.5 years, so I'm sure I have something to cover if it is incorrect:
Application Documents
Current and previous passports
BRP
Life in the UK test – I have my test scheduled for 25 July
Husband’s passport
Applicant and sponsor signed declarations
Financial Documents
Payslips covering 6 months (January - August - they are paid in advance)
Bank statements to correspond with 6 months of payslips
Letter from employer
P60
Accommodation Documents
Land registry document
Latest mortgage statement
Latest Council tax bill
Since we recently moved into our house, should I have documentation of the lease on our last accommodations?
