From 2026, PPN 006 will play an increasingly important role in how sustainability, carbon reduction, and supplier accountability are assessed across NHS procurement. PPN 006, although presented as a procurement policy notice, represents a wider shift in how the NHS evaluates environmental performance, supplier credibility, and long-term value.
For organisations supplying goods, services, or works to the NHS, PPN 006 is not just a compliance exercise. It is becoming a defining factor in how contracts are awarded and how suppliers are expected to support the NHS’s Net Zero goal.
What is PPN 006?
PPN 006 is the UK government’s procurement policy that establishes how Carbon Reduction Plans (CRPs) must be considered when awarding public sector contracts. It replaces the earlier PPN 06/21 and has been updated to align with the Procurement Act 2023 and the Procurement Regulations 2024.
Within NHS procurement, it underpins the requirement for suppliers to submit a CRP that clearly demonstrates:
- A commitment to Net Zero emissions.
- A defined baseline and current emissions footprint.
- Measurable actions to reduce emissions year on year.
These requirements align directly with the NHS Net Zero Supplier Roadmap, making CRPs a core part of NHS tender evaluations.
Why PPN 006 Matters More for the NHS in 2026
Although the fundamentals of PPN 006 remain unchanged, 2026 represents a significant milestone for NHS suppliers. The Procurement Act 2024 establishes new public procurement thresholds, which will take effect in January 2026. This is predicted to bring more NHS contracts into scope, increasing the number of procurements where CRPs are mandatory or heavily weighted.
For NHS suppliers, this means:
- Sustainability requirements applying data across a wider range of contracts.
- Increased scrutiny of carbon data, assumption, and reduction measures.
- Greater emphasis on delivery and progress, not just stated ambition.
CRPs are no longer viewed as a pass-fail document. Instead, they are becoming a point of differentiation.
How PPN 006 is Applied in NHS Procurement
The NHS has been clear about its expectations. CRPs are now integrated into procurement processes and may be required regardless of contract value, where relevant and proportionate.
In practice, this means that:
- Generic or template CRPs are increasingly contested.
- Poor quality can undercut offers that are otherwise strong.
- Suppliers must demonstrate alignment with Net Zero targets and timelines.
For many organisations, this requires a shift from creating one-off documents to maintaining living, data-driven CRPs that can be confidently reused across NHS tenders.
When NHS Suppliers Should Do Now
Our experts recommend the following steps based on their experience with NHS facing organisations.
Step 1: Review your carbon reduction plan
Ensure it adheres to current NHS and PPN 006 advice and reflects genuine progress rather than historic commitments.
Step 2: Improve emissions data quality
Strengthen Scope 1, 2, and the relevant Scope 3 reporting to aid credible decision-making.
Step 3: Integrate Sustainability into bid strategy
Treat your CRP as an integral component of your NHS tender response, not as an appendix.
Step 4: Prepare for increased scrutiny
Be ready to evidence assumptions, methodologies, and delivery plans if changed.
How Enistic Can Support NHS Suppliers
We help organisations supplying to the NHS to:
- Develop PPN 006-compliant aligned with NHS Net Zero requirements.
- Measure and manage emissions through carbon footprints, LCAs and sustainability reporting.
- Centralise sustainability and supplier data to support multiple NHS tenders efficiently.
- Use AI to reduce manual reporting and accelerate insight generation.
- Turn NHS sustainability requirements into a competitive advantage, not an administrative burden.
PPN 006 is a clear signal of how NHS procurement is evolving. Suppliers that act now will be better positioned to win contracts, build long-term partnerships, and support the NHS on its journey to Net Zero.
