You was correct with 2 years. It’s an average of 3months-3 years depending on the type. -Identity (also known as age) checks are 3-6months until they vanish.
-Anti-Money Laundering are usually 3 years
-Affordability checks are 12 months.
-Gambling affordability checks are 24 months.
-The rest are 12 months.
