I am applying for ILR in few days time. One of the required documents are payslips. Does that mean ALL PAYSLIPS to cover ALL 5 years (HSMP category)?

Thanks

Don't take this as advice but if you have P60 to cover the whole year then I see no reason to include Pay slips for the whole past Five years but do include Pay Slips definitely for the last three months. If you get your pay monthly then do it for the whole year as they will only be 12 pay slips.
