UK4 - Tender Notice
Summary of the contracting process

Thameslink Southern Great Northern Limited (TSGN) is procuring planned preventative and reactive maintenance for a wide range of compressed air equipment across its railway estates. The requirement covers machinery and compressor repair and maintenance services, supporting the continued operation of equipment used across the organisation’s railway estate. This is a specialist maintenance services opportunity for suppliers able to work with compressed air systems and respond to both scheduled servicing needs and unplanned equipment faults. The work is delivered across the United Kingdom. TSGN is a public undertaking and the buyer for this procurement.

The procurement has reached tender: TSGN invited suppliers to submit offers through a competitive flexible procedure using an invitation to participate and invitation to tender. It is an open procedure, with electronic submission allowed in English. Enquiries close at 17:00 on 18 September 2026, and expressions of interest are due by 23:59 on the same date. The award decision is due by 23:59 on 8 January 2027. The contract is scheduled to run from 1 April 2027 to 30 September 2030, with a possible performance-based 18-month renewal extending to 31 March 2032. The estimated value is £380,000 excluding VAT, or £456,000 including VAT. Evaluation is weighted 65% technical questions and 35% pricing.

This opportunity suits a specialist industrial maintenance contractor with practical experience servicing, inspecting and repairing compressed air systems and compressors. Suppliers should be able to provide planned preventative maintenance alongside reactive fault response across a railway estate, coordinating work across multiple operational locations and maintaining equipment reliability. The requirement is likely to suit businesses with suitably skilled engineering teams, robust fault-response arrangements and the capacity to manage both scheduled and urgent maintenance activity. Experience of delivering machinery maintenance in safety-critical, transport or other operationally sensitive environments would be commercially relevant, particularly where work must be planned around ongoing estate operations. The technical element carries greater evaluation weight than price, so suppliers should be prepared to demonstrate the quality and effectiveness of their maintenance approach.
