Yorkshire Water has gone out to tender with an AMP8 contract for technical consultancy, engineering design, technical assurance and specialist support services with an estimated total value of £80 million.

The water company intends to establish a multi-supplier Framework Agreement for the provision of services services required to deliver its AMP8 2025-2030 investment programme.

The framework will provide a single commercial route to access a broad range of technical capabilities, supporting Yorkshire Water's Engineering, Asset Management and Commercial functions. It will replace existing Technical Services and Technical Assurance frameworks and ensure continuity, resilience and flexibility in securing specialist expertise.

The framework will include multiple Lots reflecting different categories of technical need, including project-level engineering support, independent technical assurance, complex multi-disciplinary design services, and strategic design capability development. Further detail on each Lot is available in the procurement documents.

Current estimated start and end contract dates are 1 July 2026 to 30 June 2030 with a further possible extension option up to 30 June 2032.

The contract is being tendered in the following Lots:

Lot 1. Technical Services (Minor Packages of Work) - £12.7 million

Provision of project-level technical services to support Yorkshire Water's AMP8 investment programme. Services include engineering support, feasibility studies, options development, detailed design, and associated technical advisory tasks.

Suppliers may also be required to provide CDM Principal Designer duties and other discipline-specific engineering support.

Work under this Lot will typically be delivered as small to medium-sized task orders.

Multiple suppliers will be appointed to ensure flexibility and access to specialist capabilities across a range of engineering disciplines. The scope is intended to support both standalone tasks and short-duration assignments in line with project requirements.

Lot 2. Technical Assurance - £4 million

Provision of independent technical assurance services to support Yorkshire Water's engineering, programme and project governance needs. Services include independent design reviews, technical audits, readiness assessments, and other assurance activities required to confirm compliance with applicable standards, specifications, and regulatory expectations.

The Lot is structured to appoint a primary assurance provider, with a secondary supplier to provide resilience and surge capacity. The scope supports assurance across a range of asset types and project delivery stages.

Lot 3. Health & Safety Assurance

Lot 4. Environmental Assurance

Lot 5. Design Partner (Complex Project Delivery) - £13.3 million

This Lot covers the delivery of multi-disciplinary design services for Yorkshire Water's larger or more complex projects. Suppliers will take responsibility for providing end-to-end design capability, from feasibility and option development through to detailed design and support to construction delivery.

Work is expected to be allocated through mini-competitions for defined programmes or significant design packages. The Lot is intended to secure design partners with the capability and capacity to support long-term strategic programmes and to ensure consistency, quality, and delivery performance across Yorkshire Water's major investment activities.

Lot 6. Strategic Solutions Partner

Cancelled - no contracts will be awarded related to this lot

Lot 7. Technical Design Partner - £50 million

This Lot covers strategic technical design capability to support Yorkshire Water's long-term planning and programme development. Services include full design development, digital engineering support, maturity development for PR29 solutions, collaborative capability building, and provision of ongoing strategic design expertise.

The Lot is expected to appoint a single supplier (or consortium) able to supplement Yorkshire Water's internal capability and provide continuity, innovation, and technical leadership across multi-year programmes.

Framework to operate on multi-supplier basis and Yorkshire Water to award calloff contracts

The framework will operate on a multi-supplier basis, with Yorkshire Water awarding calloff contracts - prices for call-offs will be determined using the rate cards and pricing schedules established at tender, with the ability to confirm or adjust pricing where permitted by the call-off process.

Call-off contracts may be awarded either directly, where the framework provides an objective method to identify the most suitable supplier for a defined requirement, or following a further competition among the suppliers appointed to the relevant Lot.

Different Lots may use different allocation routes, including direct award, nomination routes or minicompetitions, depending on the nature of the work.

Yorkshire Water said it will apply the framework rules consistently to ensure transparency, fairness and proportionality in allocating work, while enabling flexibility to meet programme needs. T
