The pace of vaccine rollout in Britain boosted hope for the services firms, pushing to its highest since May 2014.
Bank of England will be holding off injecting more stimulus into the economy until lockdown across the country is eased.
Tim Moore, economics director at HIS Markit said, "while the UK economy is on course to contract sharply during the first quarter of 2021, businesses remain confident that pent-up demand and an easing of pandemic restrictions will provide a springboard to recovery later this year."
