UK4 - Tender Notice
Summary of the contracting process

Thameslink Southern Great Northern Limited (TSGN) is seeking a graffiti detection system for use in concealed toilet environments. The requirement is for detection technology, with sensors central to the goods being purchased; graffiti removal services are also included in the item classification. Delivery is in the United Kingdom, with the location identified only at country level. This is a rail-utilities procurement for a single lot, covering the system rather than a separately described installation or operating service. Suppliers working in sensor technology, monitoring systems or solutions for identifying graffiti in enclosed toilet settings are the most directly relevant.

TSGN invited offers through a four-stage competitive flexible procedure under the Procurement Act 2023. The enquiry deadline was 15 October 2026; expressions of interest were due by 28 October 2026 at 00:00. The stated contract period runs from 15 August 2027 to 14 August 2030, with an optional extension of up to 36 months, to a maximum end date of 14 August 2033. The single lot has a gross estimated value of £1,440,000. The evaluation weights technical quality at 60%, social value at 5% and price at 35%. The award decision was scheduled by 28 July 2027. Bids are to be submitted in English; the procedure information says electronic submission is not allowed.

This opportunity is best suited to suppliers able to provide detection technology for graffiti in concealed toilet environments, including suitable sensor hardware and a system that works in enclosed rail toilet spaces. Technical quality carries most of the evaluation weight, so suppliers should be able to demonstrate that their proposed approach meets the operational requirement, rather than compete on price alone. Social value also contributes to the assessment. The requirement may suit specialist sensor manufacturers, systems integrators and technology providers with relevant experience in detection or monitoring installations. The scale is a single, substantial system procurement with a multi-year contract and a possible extension, making delivery capability and the ability to support performance over time commercially relevant.
