What is social value in procurement? Understanding the 2026 regulatory landscape

Social value in procurement refers to the additional economic, social, and environmental benefits that private sector organisations must deliver alongside goods or services when tendering and delivering for public contracts. This summary focusses on UK government procurement with a focus on transport and infrastructure sectors.

In the UK social value has become part of UK central government procurement strategy. The concept has evolved from a voluntary consideration in 2012 with the introduction of the Public Services (Social Value) Act 2012. In 2020 all central UK government departments are required to use the Social Value Model (Cabinet Office) as outlined in Procurement Policy Note (PPN 06/20). It is viewed as a robust regulatory framework and today social value is increasing viewed as part of Environmental, Social, Governance (ESG) compliance. 

The evolution of social value: From the 2012 act to present-day procurement policy

The evolution of social value into UK public procurement has developed and grown significantly since 2013. 

Foundations: The 2012 social value act

The Public Services (Social Value) Act 2012 was Introduced as a Private Member’s Bill by Chris White MP.  The Act emphasised three pillars:

• Economic Impact: Supporting local jobs and Small Medium Enterprises (SMEs)
• Social Benefits: Enhancing community well-being through fair wages and apprenticeships
• Environmental Considerations: Reducing carbon footprints and promoting sustainability.

Tightening up regulations from 2012 – 2020

The Modern Slavery Act 2015 introduced supply chain accountability. This Act requires all UK based firms with over £36 million annual turnover to publish annual transparency statements. Procurement Policy Notes (PPNs) like 02/23 further mandated risk assessments for forced labour in high-risk sectors (e.g., construction, healthcare) 

Post-Brexit procurement reform: New requirements for social value in public sector contracts

Post Brexit 

Procurement Policy Note (PPN) 06/20, introduced in September 2020, which came into effect from 1 January 2021, post Brexit mandates the explicit evaluation of social value in central government contracts. It builds on the Public Services (Social Value) Act 2012, requiring a minimum 10% weighting for social value in tender evaluations.  

PPN 06/20 applies to “in-scope organisations”, which include:

1. Central Government Departments
2. Executive Agencies
3. Non-Departmental Public Bodies (NDPBs)

These organisations are mandated to follow PPN 06/20 for all procurements covered by the Public Contracts Regulations 2015. The policy became mandatory for new procurements starting from January 1, 2021.

Additionally, PPN 06/20 applies to contracts in sectors such as water, postal services, and transport if they involve regulated utility activities. However, it excludes private utilities and certain defence and security contracts under the Ministry of Defence.

Local authorities, NHS bodies, and police authorities are also encouraged to adopt the principles of PPN 06/20 but are not strictly mandated unless specified in their procurement frameworks.

2026: A strategic, outcomes-driven era

The National Procurement Policy Statement (NPPS), effective from February 2025, solidified social value as a strategic priority. Key changes are: 

1. MAT Over MEAT: Replacing “Most Economically Advantageous Tender” with “Most Advantageous Tender” to prioritise long-term societal benefits over cost.
2. Localised Impact: Authorities must align procurement with regional growth plans, exemplified by councils like Waltham Forest using data hubs to target community needs.
3. ESG Integration: The NPPS ties social value to broader Environmental, Social, and Governance (ESG) goals, requiring disclosures under frameworks like the ISSB S1/S2 standards.

Regional variations: How local authorities interpret social value in transport tenders

Local authorities, NHS bodies, and police authorities are also encouraged to adopt the principles of PPN 06/20. However this is not strictly mandated unless specified in their procurement frameworks. Increasingly local and devolved authorities have included social value in their transport tenders and local authority procurement frameworks. 

Examples include

• Greater Manchester Combined Authority thorough their transport body Transport for Greater Manchester included social value at 5 % in a drive to create local social impact priorities.
• Transport for London has included a focus on social sustainability using Strategic Labour Needs and Training and using social value not responsible procurement. 

As yet there is no regional procurement template to follow with each form of local government adopting their own approach to quantify social value in tenders.

How to measure social value: Quantification and communication strategies

Measuring social value effectively requires a combination of quantitative and qualitative indicators to ensure that this can be measure effectively. The two most popular methods to measure social value in government procurement since January 2021 are: 

1. Question and answer 

This relies on question and answer e.g. describe the social value that will delivered as part of this contract? This approach is qualitative only and is the simplest and easiest way to include social value.

2. Using a standardised framework e.g. National TOMs Framework (Themes, Outcomes, Measures)

Tools like the National TOMs Framework (Themes, Outcomes, Measures) which assigns financial proxies to outcomes, the TOMs Framework allows a financial value to bids to quantify their contributions in monetary terms. For example the financial proxy of 1 Full time job leads to £27,000 of additional social economic benefits.

However there have been criticisms that this approach is too academic, leads to unrealistic outcomes by encouraging over bidding and the benefits are purely academic with no auditing or detailed proof of financial proxies.

Other quantification methods

Another method is Social Return on Investment (SROI), which calculates the value of social, environmental, and economic outcomes relative to the financial cost of an initiative. For example, if a program generates £100,000 in social value with a £50,000 investment, the SROI ratio would be 200%, demonstrating significant impact per pound spent.  However this information is very difficult to calculate at procurement state and has not been used in UK government procurement. 

Beyond metrics: Creating compelling social value narratives in your bids

Crafting a compelling social value narrative in procurement bids requires a focus: 

1. Answering the question 
2. Delivering a vision for the contract for example using stakeholder testimonials and community impact case studies adds credibility and emotional depth, demonstrating how your initiatives have delivered tangible benefits e.g. number of apprentices.

To create a strong narrative, follow bid writing best practices

Monetary valuation: Translating transport-specific outcomes into measurable impact

Monetising the social benefits of transport and infrastructure bids requires an agreed approach to capture the known benefits. Examples include: 

• Job creation 
• Training provided 
• Spend with SMEs
• Carbon savings

Central to this process is cost-benefit analysis (CBA), a methodology endorsed by the UK Treasury Green Book to evaluate projects by comparing lifetime costs (e.g., construction, maintenance) against monetised benefits e.g., reduced travel time, accident prevention. Given transport is a large employer, outcomes like local employment, where a transport project creating 500 jobs could generate £10M+ in economic value through wages and productivity gains

The *Value for Money (VfM) framework ensures accountability, combining Benefit-Cost Ratios (BCRs) with qualitative metrics. For example, the Bucharest-Brasov Highway achieved a BCR of 2.1 by reducing congestion costs by €120 million annually while fostering regional economic integration. The Green Book’s emphasis on **strategic alignment** further mandates that projects demonstrate wider social returns, such as improved accessibility for marginalised communities or SME growth.  

What this means at a tender stage tends to be a number of financial proxies that bidders complete e.g. X jobs delivered during the contract delivery £X in additional social value.

Digital solutions: Tools and dashboards for demonstrating social value compliance

There are a number of digital solutions to demonstrate social value compliance. However, the challenge of any tool portal is that social value information is business wide so any solution needs to be able to capture business wide metrics and any automation comes at a cost.

Winning public sector contracts: Social value model integration strategies

Since 2020, Social Value Model has been popular way to ask about social value in transport and infrastructure tenders.  But it is not the only way. (Link to this section: How to Measure Social Value: Quantification and Communication Strategies)

In the bid social value is generally 10% of quality score but can be lower in local government at c 5%. No matter if it is 5 or 10% social value is important to get right and is a a critical differentiator for competitive advantage in tenders.

If a tender uses the Social Value Model 

• Map your proposal to the NPPS’s five core missions (e.g., economic growth) and identify where work is already happening based on spend e.g. in the bus industry with a large number of bus drivers apprentices can be an area of focus along with skills development (£5,000 per trainee) or SME spending where possible(1.5x multiplier for local suppliers).
• Pre-bid preparation is key. I would recommend conducting  stakeholder mapping to align with buyer priorities to ensure the solution meets clients and wider stakeholder requirements. 
• Detailed case studies combine quantitative metrics with qualitative case studies.

Community-centered approaches: Collaborative stakeholder engagement for maximum impact

Adopting community-centered approaches in public projects ensures sustainable and impactful outcomes by fostering collaboration with local stakeholders. The first step is local stakeholder mapping, which identifies key groups such as residents, businesses, and community leaders. This process helps prioritise stakeholders based on their influence and interest, ensuring tailored engagement strategies for maximum participation.

Effective public consultation strategies are essential for gathering input and building trust. However these are often not allowed at bid stage. Instead, I would recommend meetings and focus groups to gain feedback as to community feedback. For example, structured consultations can inform the development of community investment plans, which allocate resources to initiatives like local job creation, infrastructure improvements, or environmental sustainability.

Partnerships with the Voluntary and Community Sector (VCSE) can help deliver social inclusion initiatives, such as programs targeting underrepresented demographics or improving access to essential services.

From bid to delivery: Implementing social value in public sector contracts

Implementing social value in public sector contracts requires continuity from bid commitments to operational delivery. The process begins with contract mobilisation, where social value commitments outlined in the tender are integrated into the contract. This includes extracting commitments from Social Value Delivery Plans and embedding operational KPIs to measure outcomes such as local job creation, carbon reduction, or SME engagement. This ensures project delivery assurance.

Engaging delivery partners is crucial for achieving social value objectives. Public sector buyers often collaborate with Tier 1 and Tier 2 suppliers to cascade social value requirements throughout the supply chain, fostering local economic growth and ethical sourcing practices. Ensuring there are named roles to deliver requirements along with regular communications can ensure that delivery of social value actually happens! 

Governance frameworks: Ensuring accountability for social value commitments

 As mentioned above, effective governance structures are critical to delivering measurable social value in public procurement. 

Public sector governance 

Under the Procurement Act 2023, authorities must establish strategic delivery boards, such as Manchester City Council’s Social Value Governance Board, to oversee compliance, set priorities, and allocate resources. These boards monitor KPIs like local job creation and carbon savings.

Contractual obligations are central to accountability. The Procurement Act 2023 mandates at least three KPIs per contract (Section 68), requiring suppliers to report progress via quarterly impact reports and real-time dashboards. For example, Manchester’s governance framework plans to link payments to verified outcomes, such as apprenticeships for underrepresented groups or SME spend targets.

Audit and oversight mechanisms, including independent audits by the client or indeed  third-party auditors ensure transparency and ensure the social value outcomes are actually delivered.

Supply chain integration: Extending social value throughout your procurement network

Integrating social value to flow down into the supply chain is essential since spend in transport and infrastructure have large supply chains with opportunities of introducing social value. 

Key priorities are:

• Promoting SME participation, ensuring small and medium-sized enterprises have access to public contracts. This not only supports local economies but also aligns with the National Procurement Policy Statement (NPPS). However there needs to be a balance between cost savings and SME participation.
• Working collaboratively with Tier 1 and Tier 2 suppliers is another critical step. By embedding social value criteria into contracts, businesses can encourage their suppliers to adopt practices such as hiring locally, reducing carbon emissions, or supporting community projects. 
• Supply chain transparency is vital for building trust and meeting regulatory requirements, such as the UK’s Modern Slavery Act. Leveraging technology like blockchain or procurement analytics platforms allows businesses to track materials and services from origin to delivery, ensuring ethical standards are upheld
• Developing robust ethical sourcing policies ensures transparency and accountability throughout the supply chain. These policies should address issues such as fair wages, safe working conditions, and environmentally sustainable practices. Tools like Sedex or EcoVadis can help organisations monitor supplier compliance and identify risks like forced labour or unsustainable sourcing.

Measurement protocols: How to track and report social value outcomes effectively

Tracking and reporting on social value outcomes depends on the preferred method of the client. In terms of cost and ease of use, my suggestion are below;  

• Quarterly impact reports are the currently preferred approach and allow information to be presented regularly to be presented meaningfully.
• Real-time dashboards sound great in practice but are expensive to implement and often raise questions over data quality.
• Independent audits are helpful to have to provide reassurance and are suggested to happen every 2 – 3 years. 

The future of social value in UK public procurement

The future trends in procurement in social value is set to be shaped by

• AI in tender preparation and evaluation – This will speed up data collection and analysis allowing key data to be reported
• Environmental sustainability – will also play a central role, with policies like Environmental Net Gain (ENG) requiring public contracts to contribute positively to natural ecosystems which will undoubtedly evolve over time. ENG expands on biodiversity net gain by incorporating broader environmental benefits, such as improved air quality and carbon sequestration, into procurement strategies.

As procurement evolves, the challenge is to remain competitive in this increasingly value-driven landscape.
