Key trends shaping procurement in 2026
Decarbonisation and net zero
All major public bodies have net zero commitments driving procurement transformation. Fleet electrification, renewable energy, sustainable construction, and green FM are all growing rapidly. Contracts now routinely include carbon reduction KPIs.
Supplier impact: Growing spend on EV infrastructure, retrofit, renewable energy, and sustainability consultancy across all public bodies.
Digital transformation
The Government Digital Service and NHS England continue to drive digital transformation across the public sector. Cloud migration, legacy system replacement, data analytics, and AI adoption are driving significant technology procurement.
Supplier impact: Continued strong demand for cloud software, digital delivery teams, data platforms, and AI solutions.
Building safety and compliance
Following the Grenfell Tower fire and the Building Safety Act 2022, fire safety remediation and building safety compliance are major spending priorities — particularly for housing associations, local authorities, and NHS estates.
Supplier impact: Significant spend on fire risk assessment, passive fire protection, cladding remediation, and building safety consultancy.
Social value and community benefit
Social value requirements continue to strengthen across all procurement. The Procurement Act 2023 embeds social and environmental considerations further. Buyers are becoming more sophisticated at evaluating social value commitments.
Supplier impact: Suppliers with genuine, measurable social value programmes have increasing competitive advantage.
SME and market access
The Procurement Act 2023 introduced new measures to improve SME access including mandatory consideration of SME barriers, breaking contracts into lots, and the Supplier Registration Service reducing administrative burden.
Supplier impact: Improving conditions for SMEs — lower barriers to pre-qualification and more accessible procurement processes.
Procurement Act 2023 implementation
The biggest procurement reform in a generation came into force in February 2025. Pipeline notices are now mandatory, creating systematic advance visibility of upcoming contracts. New notice types increase transparency throughout the contract lifecycle.
Supplier impact: More advance intelligence available to suppliers — pipeline notices give 12 months warning of upcoming procurements above £2m.
SME procurement — progress and challenges
The UK government has a target to spend £1 in every £3 with SMEs. Progress has been mixed — direct SME spend has been easier to increase than tier-1 contract awards. Key measures to improve SME access include:
- ✓Supplier Registration Service — reduces pre-qualification burden for SMEs
- ✓Contract lot structure — breaking large contracts into SME-accessible lots
- ✓Procurement Act 2023 — strengthened requirements to consider SME barriers
- ✓Mystery shopper service — allowing SMEs to report procurement barriers
- ✓Find a Tender improvements — better searchability of below-threshold contracts
- ✓Payment terms — government target of 30-day payment terms with supply chain
