When Atwell first came to Britain, she initially earned only a few pounds a week. By the mid-1950s, this had shot up to over $10,000. By 1952, her popularity had spread internationally. Her hands were insured with Lloyd's of London for £40,000 (the policy stipulating that she was never to wash dishes). She signed a record contract with Decca, and her sales were soon 30,000 discs a week. She was by far the biggest selling pianist of her time. Her 1954 hit "Let's Have Another Party" was the first piano instrumental to reach number one in the UK Singles Chart.
