Okay, so the earliest date you can apply for ILR is 28 days before you reach 5 years in the UK, which is 29/06/2022.
The latest date you can apply is the expiry date of your current BRP card, which is 27/07/2022.
As long as you submit your online application between 29th June and 27th July, you can use the Super Priority service if it is available.
You CANNOT apply or use priority AFTER expiry because that would mean submitting an invalid application.
However, there have not been many Super Priority slots available recently due to an increase of applications from Ukraine, so you’ll likely need to try submitting your application at about midnight or 1am to see if the priority option is available to you. You may need to try on a few different days if it doesn’t show up right away.
