How long do you have from application to enrol biometrics?

Hello,

I've just completed my application for IRL Set O, online. Am just to the payment page, and wondering if I should go for regular service, waiting 6 months, or 5 day priority. My issue is that my visa was granted 02 March 2015, arrived in UK 22 March 2015, and visa expires 01 February 2020, just prior to my 5 years continuous residence.

I understand that should I meet the 5 year criteria at the time my application is decided upon, my ILR will be granted.

Should I apply under the 6 month route, there is no doubt that I will be eligible for ILR when a decision is made.

However, I do not want want to wait so long for a decision.

The priority will give a decision within 5 days of biometrics; however, I wanted to know how what the maximum time between submitting my application and enrolling biometrics can be. Am I able to wait a month to enroll biometrics on 2 March, so I reach 5 years continuous residence by the time a decision is made?

I don't want to pay for priority if I have to submit my biometrics in 15 days, and therefore fail to meet the residency requirement.
