The question that matters
Most social value measurement stops too early
Tracking what was promised in a contract is useful. But it answers a limited question. The Social Value Engine is built to go further.
Where most tools stop
Most social value platforms track commitments through a procurement process. They help funders and contractors report on KPIs: jobs created, apprenticeships delivered, pounds spent locally.
That answers the question:
"Did the supplier do what they said they would?"
Where SVE goes
The Social Value Engine measures what changed in a community. It uses accredited SROI methodology to value outcomes, not just count outputs, so investment decisions are shaped by evidence of what works.
That answers a different question:
"Did we improve people's lives?"
What sets SVE apart
Valuing the Invaluable
SVI accredited
Independently assessed against the Principles of Social Value. Every analysis on the platform follows Social Value International methodology, so your results carry the credibility that funders and regulators recognise.
Outcomes over outputs
Most social value tools track what was promised in a contract. The Social Value Engine measures what changed in a community, evidencing societal benefit through SROI rather than counting the outputs a supplier committed to at tender stage.
Every figure, fully traceable
No black boxes. Every outcome links to its proxy source, quantity, and SROI adjustments. Your reports show the working, so commissioners, auditors and boards can follow every pound from input to impact.
"We always knew our programmes made a real difference. Now we can prove it in a language that resonates with senior decision-makers."
Who we help
Used across the public, private and voluntary sectors
How organisations measure social value depends on what they are trying to learn. The Social Value Engine helps each sector measure, report and maximise impact in the way that matters to them.
Co-ownership
Built together, owned together
The Social Value Engine was created by East Riding of Yorkshire Council and Rose Regeneration, and is still co-owned by both. It was built by a council that commissions public services and a consultancy with over 30 years of SROI methodology.
That combination shaped the platform: where other tools report on procurement KPIs, the Social Value Engine reports on societal benefit, using accredited methodology and peer-reviewed financial proxy sources.
