This contracting process concerns the ongoing provision of Detection and Enforcement Infrastructure Maintenance Services, initiated by Transport for London (TfL). The initiative falls under the services category, specifically targeting the closed-circuit television sector, and is primarily focused on the UKI region, centred in London. The procurement began in 2014 and entered the operational stage on 20 September 2026, with an initial contract length of five years, later extended to span ten years in total.
