Summary of the contracting process

Chiltern Railway Company Limited procured the supply of manufacturer-approved filters for its mixed fleet of diesel multiple units and diesel locomotive-hauled Mk5a coaches. The filters are used when changing fluids and carrying out scheduled rolling-stock maintenance, supporting safe operation, performance and continuity of supply. The requirement covers the complete basket of specified filter products, including only the listed makes and part numbers; substitutions are not accepted. Orders are placed during the agreement to maintain inventory at maintenance sites. Delivery supports Chiltern’s passenger services from London Marylebone through Buckinghamshire, Oxfordshire and Warwickshire to Birmingham, Stratford-upon-Avon, Oxford, Aylesbury, Bicester and other West Midlands destinations. It also covers East West Railway services from Oxford to Bletchley and any extensions Chiltern operates.

The procurement is complete and was awarded to Filtration Control Ltd, with an award date of 14 August 2026. It used a selective competitive flexible procedure for one lot, with a maximum estimated value of £840,000 excluding VAT (£1,008,000 including VAT). The initial awarded contract period is 4 September 2026 to 3 September 2031, with an option for a mutually agreed 12-month extension to 3 September 2032. A standstill period ends on 26 August 2026, and signature was scheduled for 4 September 2026. Evaluation weighted commercial price at 50%, legal response at 35% and technical response at 15%. The technical assessment included a pass/fail requirement concerning a Department for Transport Umbrella Direct Agreement and evaluation of the mobilisation plan. The opportunity was identified as suitable for SMEs.

This award indicates a substantial, repeatable requirement for specialist rail filtration across a mixed rolling-stock fleet. A credible future competitor would need to supply every product in the specified basket, using the manufacturer-approved makes and exact part numbers required to protect component warranties, while managing any future changes, redesigns or discontinuations. The buyer’s ordering model favours suppliers able to maintain reliable inventory and fulfil orders to railway maintenance sites across the operating network. Technical capability includes understanding scheduled train maintenance and demonstrating a robust mobilisation plan with milestones, critical-path sequencing, dependencies and risk controls. Suppliers would also need to satisfy the Department for Transport Umbrella Direct Agreement requirement, present contract and SLA changes with limited impact on Chiltern’s risk position, and offer competitive pricing across the full range.

Notice Information

Notice Title

Rolling Stock Fillters Supply

Notice Description

Chiltern Railways operates commuter/regional rail passenger services from its central London terminus at London Marylebone along the M40 corridor to destinations in Buckinghamshire, Oxfordshire and Warwickshire, as well as long-distance services to the West Midlands along two routes. Services on the Chiltern main line run from London Marylebone to Birmingham Snow Hill, Stratford-upon-Avon and Oxford, with some peak hour services to Kidderminster. Chiltern Railways also runs trains on the London to Aylesbury Line to Aylesbury (with some trains terminating at Aylesbury Vale Parkway instead), on the Princes Risborough to Aylesbury and Oxford to Bicester branch lines. This Procurement also covers East West Railway from Oxford to Bletchley or any other extensions that Chiltern Railways are contracted to operate. Chiltern Railways operates a mixed fleet of rolling stock to fulfil its rail passenger services. The fleet consists of both diesel multiple units (DMUs) and diesel loco hauled Mk5a coach stock. The fleet maintenance plan set out what maintenance tasks are required for the rolling stock and at what maintenance periodicities. The maintenance tasks include changing various fluids and filters to ensure the safe operation and maintain the performance of thefleet. As such Chiltern Railways require one contract to supply these filters to ensure continuity of supply, so that the maintenance tasks are performed at the correct intervals. To protect manufacturer warranties, only the manufacturer's recommended filters can be used which forms the specifications of this ITT. Only the filter makes and part numbers identified in the specifications are to be supplied and no substitutions will be accepted. Bidders must be capable of supplying all products within the basket of goods that make up the Specifications. No bids will be accepted where a Bidder is not able to supply all the product types that make up the specifications. Chiltern Railways will place orders for the products throughout the term of the agreement so that sufficient inventory levels can be maintained at its maintenance sites accordingly.
