Portfolio, Churchill's cleaning division, has secured a three-year contract extension with English National Ballet (ENB) beginning in late July.
Portfolio will deliver general cleaning services at ENB's new premises at London City Island, Canning Town, where the company will move this summer from its current base in South Kensington.
In keeping with its aim to limit industry impact on the environment, Portfolio by Churchill will make use of the Purex cleaning system, which will help to raise standards without using industrial chemicals.
English National Ballet is joined by English National Ballet School at the new site. At 93,000 square feet, the site is four times the size of current buildings and will provide a dedicated space for dancers, choreographers, costume-makers, musicians and students. Situated near Stratford, the English National Ballet will join other new cultural landmarks in the area, including Sadler's Wells Theatre, the London College of Fashion, and the V&A East project.
Adrian Wyer, facilities manager at English National Ballet, said: "English National Ballet is keen to commence its new working partnership with Portfolio by Churchill as it moves into a new, purpose-built home. Delivery of exceptional cleaning services along with new methods of environmentally focused cleaning will be the main basis of this partnership."
