IHG One Rewards runs five levels — Club Member, Silver Elite, Gold Elite, Platinum Elite and Diamond Elite — and every threshold above Silver can be reached by nights or by points, whichever comes first. Silver is nights only, at 10.
The headline elite benefit is bonus earning: 20% above base at Silver, 40% at Gold, 60% at Platinum and 100% at Diamond. Gold and above roll qualifying nights over to the following year, Platinum and Diamond get reward night discounts, and Diamond adds dedicated support. Gold and Platinum carry Hertz Gold Plus Five Star status; Diamond carries President’s Circle.
IHG prices reward nights dynamically and publishes no award chart. Its own tier page names "Reward Night Discounts" as a Platinum and Diamond benefit without ever stating a rate, so there is no table to reproduce here — that absence is the fact rather than a gap in our research.
Points expiry is a level benefit rather than a program rule, which is the detail most worth getting right: a Club member’s points expire after twelve months without an earn or redeem, and "Points Don’t Expire" begins at Silver.
