Summary of the contracting process

Northern Trains Limited procured liquid waste removal and drainage services for its train maintenance facilities across its network. The requirement covers removing liquid waste from train waste tanks, including coolant and oil; emptying and managing oil/water separators and septic tanks; and providing waste management and drainage maintenance. Services also include drain jetting, drain clearance, CCTV surveys and maintaining drainage systems in TrainCare Centre maintenance areas, including removing sediment such as sand. The supplier must support Northern’s environmental objectives, including reducing waste sent to landfill. It must classify and manage waste, assign European Waste Catalogue codes, document transport hazards, prepare consignment and transfer documentation, and arrange UKAS-accredited laboratory analysis for each collection.

The procurement is complete and awarded through an open competitive flexible procedure. Five bids were received, with three reaching the final stage, including two from SMEs. One supplier, Adler & Allan Limited, was selected for both the single-supplier framework and associated call-off contract. The framework award is £3,912,630 net (£4,695,156 gross), awarded on 11 August 2026; the call-off award is £3,007,123.62 net (£3,608,548.34 gross), also dated 11 August 2026. Both have a standstill period ending 20 August 2026 and a scheduled signature date of 27 August 2026. The contract period runs from 31 August 2026 to 30 August 2030, with two possible two-year extensions to 30 August 2034. Evaluation weighted cost 50%, technical quality 40% and social value 10%.

This requirement suits specialist liquid-waste and drainage contractors able to operate across a rail maintenance network and coordinate work at multiple operational sites. Credible suppliers would need practical capability in liquid waste collection, septic tanks, oil/water separators, drain clearance, jetting and CCTV inspection, alongside the capacity to respond to site-specific work orders. Environmental and regulatory competence is central: suppliers must be appropriately licensed to handle, transport and dispose of liquid and hazardous waste, classify waste using European Waste Catalogue codes, document transport controls and complete statutory waste records. Access to UKAS-accredited laboratory analysis is required for each collection. Strong performance management, responsive service delivery, environmental reporting, social value delivery and evidence-based pricing would be important when this buyer next assesses comparable provision.

NTL undertakes train maintenance activities across a number of locations. At the time of award, services are required across 11 maintenance sites, although the number of locations covered by the Framework Agreement may increase or decrease during the term of the agreement. The awarded supplier will provide services including, but not limited to: - Removal of liquid waste from waste tanks containing fluids drained from trains, including coolant and oil; - Emptying and management of oil/water separators, including sludge, water and oil; - Septic tank emptying and waste management; - Drainage maintenance and associated services.

For each waste collection, the supplier shall arrange laboratory analysis of samples through a UKAS-accredited laboratory.

Lot Information

Lot 1

Options: NTL may request additional deliverables or services that are not explicitly listed in the scope of this procurement. Where such requirements arise, pricing will be agreed within the relevant work order, subject to the following conditions: -Any pricing related to design, build, or management services must remain consistent with the rates set out in the framework. -All agreed prices must be clearly linked to comparable items already included in the framework pricing schedule. -The appointed supplier will be required to provide supporting evidence to justify the proposed pricing.

Renewal: The Contract will be let for an initial term of four (4) years. Following the expiry of the initial term, NTL may, at its sole discretion, exercise up to two (2) extension options of two (2) years each (a potential maximum contract duration of eight (8) years). Extensions may be considered where: Service performance has consistently met or exceeded the required KPIs, including compliance, responsiveness, environmental standards, and reporting obligations. Operational continuity is desirable to avoid service disruption, particularly where ongoing site-specific knowledge or specialist waste-handling expertise is beneficial. Value for money can be demonstrated, including benchmarking or a review showing that the extension period remains commercially advantageous. Regulatory compliance continues to be maintained, with the supplier remaining appropriately licensed for handling, transporting, and disposing of liquid waste. Business needs remain unchanged, and the scope and volume of liquid waste removal services are still required in line with the existing specification. If both extension options are applied, the breakdown is as follows: Initial Term: 4 years Extension Option 1: 2 years Extension Option 2: 2 years Maximum Contract Duration: 8 years total

Planning Information

Northern Trains Limited ("NTL") invited a selected group of suppliers to participate in early pre‑market engagement for the upcoming liquid waste services requirement. Suppliers were chosen based on their proven, current, or recently demonstrated capability in delivering part or all of the required liquid waste management services across the NTL network. Each supplier was invited to an individual session where NTL delivered the same presentation outlining the proposed scope, operational processes, KPIs, and required accreditations. Suppliers were invited to provide feedback on these elements and to share any examples or templates of pricing schedules for similar work, as this is a new area for NTL to formally procure. The key objectives of the pre‑market engagement were to: - Gain a clearer understanding of the liquid waste services market and supplier capabilities - Understand typical pricing methodologies for this type of service and identify any commercial or operational challenges - Assess how the contract could operate across multiple NTL locations and determine the level of project team involvement required Following pre-market engagement, work has started to develop a suitable contract. It gave the project team an understanding of what information the market needs to bid for the works, which impacted the specification development, pricing schedule and tender response questions.
