Churchill has secured a two-year cleaning deal with the Royal College of Anaesthetists (RCoA) in Holborn, London.
The contract comprises general and specialist cleaning services, as well as washroom and window cleaning across the college site, named Churchill House.
The RCoA is the third largest medical royal college by UK membership with a combined following of more than 23,000 members.
As a member of the London Universities Purchasing Consortium, the RCoA used the framework set out by the institution and released the contract to tender to five cleaning and facilities companies.
Churchill was selected by the RCoA specifically for "its commitment to sustainability, people training and development and its electronic auditing platform".
