HS1 Ltd, the company responsible for operating and maintaining the UK's High Speed 1 rail route between London St Pancras and the Channel Tunnel, has launched a pre-procurement engagement for a new Project Integrator Framework. Valued at £31 million including VAT and running for up to seven years, this framework will secure integration and programme management support across all of HS1's business departments.
This is a focused, specialist opportunity. The "Project Integrator" role is about bringing coherence to complex, multi-workstream programmes, coordinating delivery across commercial, operational, technical, and asset management functions. It is not a broad management consultancy framework, and prospective bidders should be clear that HS1 is looking for organisations with genuine expertise in programme integration, ideally within regulated infrastructure or transport environments.

What HS1 Is Looking For
HS1 Ltd's portfolio spans infrastructure maintenance, capital investment, customer and stakeholder management, and commercial asset development along the HS1 route. The Project Integrator role will sit across all of these, helping HS1 manage interdependencies, programme risks, and cross-departmental delivery challenges.
The most relevant organisations for this framework are likely to include:
- Programme management consultancies with rail, transport, or regulated infrastructure experience
- Engineering consultancies with strong programme governance and integration capability
- Organisations experienced in working within or alongside Network Rail, Transport for London, or similar complex rail environments
- Firms with a track record of managing multi-departmental or portfolio-level programmes for public sector or regulated bodies
General management consultancies without specific infrastructure or transport exposure may find the evaluation criteria challenging. HS1's operational environment is specific, and evaluators will be looking for genuine sector understanding.

Bidding Considerations
- Framework, not a single project: This agreement will run for up to seven years across multiple assignments. Your bid needs to demonstrate sustained portfolio capability, not just single-project delivery experience.
- Departmental breadth: HS1 explicitly requires support across all business areas. Structure your submission to show how your team can flex, and evidence this with examples of cross-functional, multi-stakeholder delivery.
- Governance and risk management: Regulated infrastructure environments demand rigour. Demonstrate your approach to managing long-term, complex client relationships with appropriate oversight and transparency.
- Engagement closes 12 May 2026: This is pre-procurement engagement: the formal competition will follow. Use this window to signal your interest and influence the shape of the final procurement, then prepare for the formal tender.
The seven-year duration and strategic importance of the HS1 route make this a standout opportunity for the right consultancy. If this aligns with your expertise, ensure you review the full notice and engage before the deadline. Get in touch with Thornton & Lowe to discuss your positioning and how to make the most of this pre-market engagement stage.
