The Bestseller Awards, previously the Nielsen Bestseller Awards and the Whitaker Awards, are given annually for books sold in the United Kingdom on the basis of their total number of sales, both in print and as e-books, as measured by BookScan.
In 2024 the awards are hosted by Nielsen BookData and BolognaBookPlus.
A book may be given an award if it sells 250,000 (silver), 500,000 (gold) or 1,000,000 copies (platinum).
Initially this had to be within a period of five years, but in 2017 this was extended to the period for which BookScan sales records were held: 1998 for print books and 2014 for e-books.
[5] A press-release described this as "the first in-person Bestseller Awards in three years, the last two having been held virtually or as individual presentations", and the official website of the awards, as of January 2024[update], lists the 2021 virtual ceremony as the most recent.
