Kings Langley School is a secondary school in Hertfordshire with 1,126 students aged 11 to 18 and 125 staff. It wants a cleaning contractor to start on 1 April 2027 for three years, with the option of two more one-year extensions. The process has two stages: a Procurement Specific Questionnaire first, then an Invitation to Tender for shortlisted bidders. TUPE applies, and the school wants a guaranteed cost and full delivery of the agreed hours. It has said this is not a lowest-price contest, and it may keep the service in-house if no bid is good enough.
