A case study in platforms, scale of social value and supplier behaviour
Across the Public and Housing Sector, social value has become a central pillar of procurement, investment and reporting. Large buyer organisations now speak in the language of millions, millions invested, millions of social value created, millions of benefit delivered to communities.
But when you look closely at how that value is actually delivered, a more uncomfortable question emerges.
Is the system economically and operationally viable?
The numbers that don’t add up
Take a large housing provider with close to £800 million in annual turnover (based on London Stock Exchange and published annual reports) and over £1 billion flowing through its supply chain each year. At even a modest 0.5–1% social value investment expectation across procurement, that represents between £5 million and £10 million of real resources — not proxy value — that should be flowing annually through suppliers into employability, environment and community programmes.
Within this case example, the organisation reports approximately £7 million of community investment in their annual report, representing £140 million of claimed proxy social value. £2M of this was collected from their partners.
Yet within the same system, they use a matching platform to connect suppliers with tenant and community-led projects. That platform reports, in a separate public disclosure with the housing association social value team support, just £62,000 of money and in-kind donations across 55 projects and around 200 hours of volunteering. 
This is not a separate figure. It is part of the same £7 million.
And this is where the problem becomes impossible to ignore.
If £62,000 and 200 hours of volunteering represent the visible, structured portion of delivery, the question is unavoidable: what system was used to deliver the remaining £6,938,000?
This is not simply a reporting gap. It is a platform design and engagement problem — and the distinction matters.
When looking at similar reports from other housing associations using the same platform, the engagement level stays £50-200k money and in-kind donations and 200-500h volunteering (25-60 days) on annual level. This, in £500M- £1bn annual procurement budgets.
To be frank, this level of donation should be coming from ONE major supplier, not 100-150 suppliers in total.
Platforms are not neutral
Platforms shape behaviour. That is not a criticism of any particular product; it is a fundamental truth about how technology mediates human activity. Social Value tech solutions as concept are very different, and shape the landscape.
If a platform is built around small, transactional requests — food bank donations, surplus materials, ad hoc volunteering days — then that is precisely what it will produce. Suppliers respond to what is easy, visible and accepted within the system. When the path of least resistance leads to a pallet of materials or a small one-off donation, large suppliers with contracts worth tens of millions can meet their social value expectations through contributions that bear no relationship to their contract value, their capability, or the scale of community need they were commissioned to address.
The platform enables participation. But at the minimum possible level.
This suits suppliers in the short term. It does not serve communities. Literally, no new interventions nor extension of programmes can be generated with these small ad hoc donations.
The cost of managing what you’re not delivering
The operational overhead of social value at this scale is significant and largely fixed. A single social value manager typically costs between £70,000 and £120,000 annually in fully loaded employment costs. Add platform licensing, other internal coordination, procurement oversight, supplier engagement, and the reporting burden, and the total cost of running the function rises further still.
Against that backdrop, £62,000 of in-kind donations and cash contributions is not just underwhelming. It is below the cost of managing it.
The net social value of that portion of activity is negative. It would have been more productive to direct the management budget itself into the community than to run an organisational system that delivers less than it costs to operate. 
This is not an unkind observation. It is the basic principle of impact evaluation — one the sector has quietly set aside in favour of activity reports and proxy pound figures that are satisfying to produce and easy to present to boards.
The Social Value Act and the procurement policies built on it were created for a specific purpose: to harness public purchasing power for the direct benefit of people and communities. Not for the optics. Not for the annual report. When the system produces less value than it consumes in management overhead, something has gone structurally wrong — and it needs to be named as such.
Proportionality is not optional
When procurement is close to £1 billion, social value delivery cannot be built on £1,000 donations per supplier and occasional volunteering days.
It must be proportional — to contract value, to supplier capability, and to community need.
That means community, employment and environmental programmes that run for the duration of a contract, not for a single afternoon. It means structured investments, skills commitments and volunteering planned and agreed at tender stage, so that social value is a condition of appointment and not an afterthought once the contract is signed. It means choosing suppliers, in part, on the basis of what they are genuinely willing and able to deliver and holding them to it through the lifecycle of the relationship, with evidence that the outcomes occurred.
Directing suppliers to a platform after commissioning, where the dominant activity is a small donation or a one-off volunteering hour, is not social value delivery. It is social value administration with very little social value in it.
Where is the rest of the £6,938,000?
The case study returns us to the original question.
If only a small fraction of delivery is visible through structured systems, where is the rest? Is it being delivered through suppliers independently, without coordination or verification? Is it being managed across internal departments, scattered across job roles and email threads, with no central record? Is it being assumed through proxy calculation tools — where inputs and outputs are entered into a model and a pound figure emerges, without any verification that the underlying activity delivered the outcomes being claimed?
And most importantly: is it being evidenced?
Because without a system that connects supplier commitments to planned delivery, and delivery to verified outcomes, there is no clear answer to that question. There is only a number in a report, and a growing gap between what is being claimed and what can be defended.
A different kind of platform
Not all platforms are designed the same way, and the sector has been too slow to say so plainly.
Some platforms are built for small-scale engagement — transactional, low-friction, low-impact. They serve a purpose in their context. But they cannot be the infrastructure for serious social value delivery across hundreds of millions supply chain.
whatimpact is built on a fundamentally different premise: that social value should be proportional, accountable and evidenced. That the right question is not “how do we make it easy for suppliers to participate?” but “how do we ensure that participation delivers genuine, verified change in the lives of the people it is meant to serve?”
That requires matching the scale of the commitment to the scale of the contract. It requires connecting suppliers with the right VCSE partners , not just the nearest food bank, but the organisations with the programmes, the reach and the expertise to deliver structured employment, environmental and community outcomes. It requires managing those partnerships through the full contract lifecycle, with skills-based volunteering planned and committed at the outset, not coordinated ad hoc by whoever has capacity on the day. And it requires impact reporting that verifies outcomes from the people on the ground — not proxy figures applied to headcounts.
On whatimpact, our platform users, government suppliers, build years long employability programmes, donate thousands of worth service packages, £10-£75k grants and look for strategic volunteering parners. 
That is what a social value platform should do. The difference between that and a donation portal is not a matter of degree. It is a matter of purpose.
