Yorkshire Purchasing Organisation (YPO) is inviting supplier feedback ahead of procuring its next Electricity and Ancillary Services framework (reference 1337) – a high-value agreement with an estimated value of £3.6 billion (including VAT) over an eight-year term. If your business operates in electricity retail, supply, or ancillary energy services, this pre-market engagement phase is your opportunity to help shape one of the most significant utilities procurement frameworks in the UK public sector.

If you are considering engaging with this opportunity, Thornton & Lowe's bidding specialists can help you assess whether participation is right for your business and how to engage most effectively at this early stage.

Why Engage at the Pre-Market Stage?

YPO's pre-market engagement gives suppliers a rare opportunity to influence the framework's design before formal tendering begins. For electricity retailers, energy brokers, and ancillary service providers, this stage is crucial: by sharing market insights and practical feedback now, you help ensure the framework reflects genuine market capabilities and your particular strengths – putting you in a stronger position when the formal competition opens.

The framework is expected to cover electricity supply and a broad range of ancillary services for public sector organisations across the UK. Given its scale, the agreement will likely be lotted to reflect different service categories or geographies. Engaging now positions you to understand and influence that structure before it is fixed.

Considerations and Tips for Suppliers

  • Review the scope thoroughly: Examine the full notice at Find a Tender to understand the intended service breadth. Broad electricity frameworks often involve distinct lots covering supply, balancing, or value-added services.
  • Highlight innovation: Use this feedback window to demonstrate advances in energy management, smart metering, flexibility services, or sustainability – areas the public sector is increasingly prioritising.
  • Think about longevity: An eight-year agreement offers rare stability and recurring business potential. Your feedback and eventual bid should convey long-term value and adaptability as the UK's energy landscape evolves.
  • Engage visibly: Active participation during pre-market phases improves your visibility with YPO and helps set buyer expectations in ways that better align with your offering. For more on making the most of YPO frameworks, see our dedicated YPO bid writing guide.
