Churchill has been reappointed as the cleaning contractor at Caldicot School in Monmouthshire in Wales.
The new contract sees Churchill providing cleaning services for a further three years.
Churchill's relationship with Caldicot School began with the award of the original contract in 2013 when the school still occupied older premises.
Following construction of a new £36.5 million school in 2017, Churchill was retained pending the outcome of a formal and comprehensive tender process for cleaning services in 2018.
The large team of 17 staff provides daytime and evening cleaning support in addition to a comprehensive caretaking service throughout the day.
The new contract began on 1st January.
