The group said 2021 saw "strong development" in the region, which now consists of more than 1,100 hotels across a portfolio of more than 20 brands, spanning 31 countries.
The UK alone saw 13 new signings with a further 500 rooms added to Accor’s London portfolio.
The year closed with the signing of the 110-room Hyde Paradox Hotel London City, which is expected to launch in 2023.
Eastern Europe also remains a strong pipeline for the group with multiple signings in countries including Albania, Croatia, Georgia, Hungary, Moldova, Montenegro and Romania.
Duncan O’Rourke, chief executive of Accor Northern Europe, said the pace of development "accelerated throughout 2021".
"The geographical growth of our region and brand portfolio in recent years has prepared the business for expansion at pace as the world moves firmly towards recovery," he added.
