The April 2026 Procurement Milestone
As of 6 April 2026, the grace period for sustainability in the NHS has officially ended. For any supplier submitting a tender to the NHS Supply Chain, achieving NHS Evergreen Level 1 is now a mandatory requirement at the point of tender close. This isn’t just about high-value contracts anymore; it is the universal baseline for doing business with the UK’s largest employer.
In the current landscape, if you haven’t reached this maturity score, your tender will be rejected before it even reaches the quality evaluation stage. This guide breaks down the technical requirements of the Evergreen framework and the common pitfalls that lead to “Level 0” rejection.
What is NHS Evergreen Level 1?
The NHS Evergreen Sustainable Supplier Assessment is a four-tier maturity matrix designed by NHS England to track supplier alignment with the NHS Net Zero Roadmap. Level 1 (Foundational) is the gateway. It proves that your company has a credible plan and a “license to operate” within the healthcare supply chain.
The Technical Checklist for Level 1 Compliance
To secure Level 1 status, your organisation must provide evidence for three specific pillars:
1. A Publicly Committed Net Zero Goal
Your company must have a formal, public-facing commitment to reach Net Zero by 2050 at the latest. This must be integrated into your corporate strategy and clearly published on your official website. In 2026, the NHS looks for “Board-level resolutions,” meaning a simple bullet point in a brochure is no longer sufficient evidence.
2. A PPN 006-Compliant Carbon Reduction Plan (CRP)
Formerly known as PPN 06/21, the updated PPN 006 remains the technical backbone of your submission. Your CRP must include:
- Scope 1 & 2 Emissions: Direct fuel combustion and indirect energy usage.
- Scope 3 Subsets: You must report on business travel, employee commuting, waste generated in operations, and both upstream and downstream transportation.
- Board-Level Sign-Off: The document must be signed by a Director or Board member to ensure legal and operational accountability.
3. Annual Reporting Rigour
The NHS Evergreen framework is not a “one and done” assessment. Your data must be refreshed annually. If your CRP hasn’t been updated within six months of your latest financial year-end, it is technically non-compliant for a 2026 tender.
The Expertise Gap: Why Submissions Fail
In our consultancy work, we see two common errors that lead to failed assessments:
- Data Mismatch: The numbers in your Evergreen portal must match the numbers in your public Carbon Reduction Plan exactly. Discrepancies often trigger a manual audit, which can delay your tender eligibility.
- Incomplete Scope 3 Subsets: Many firms use “industry averages” for employee commuting. In 2026, the NHS expects primary data—such as actual surveys or mileage tracking—to demonstrate your Level 1 maturity.
Moving Toward Level 2 and Beyond
While Level 1 allows you to bid, Level 2 (Developing) and Level 3 (Maturing) are where the competitive advantage lies. By 2027, the NHS will begin weighting tenders toward those who can demonstrate a higher level of maturity. Achieving Level 2 requires a full Scope 3 inventory (all 15 categories), while Level 3 requires targets validated by the Science Based Targets initiative (SBTi).
Act Before the Tender Deadline
Don’t wait for a high-value tender to discover your CRP is non-compliant. A professional gap analysis can identify “red flag” data points that would trigger a rejection during the maturity check. At ESG PRO, we ensure your data is audit-ready, so you can focus on winning the contract rather than navigating the Evergreen portal bureaucracy.
