Impact Evaluation & Socio-Economic Assessment

Measure what your work actually changes

Funders, commissioners and communities want to know what difference you make. We give you the evidence — in outcomes, in social value, and in pounds — and the tools to keep measuring after we leave.

Theory of change from inputs to impact, and a chart showing outcomes with the programme compared with the counterfactual

What we deliver

  • Theory of change and impact frameworks — what you are trying to change, how, and the indicators that show it.
  • Socio-economic impact assessment — jobs, GVA, wellbeing and distributional effects of a project or programme, using Green Book-consistent methods.
  • Social value and SROI-style analysis — monetised outcomes for tenders and funding bids.
  • Independent programme evaluation — process and outcome evaluation for funders such as The National Lottery Community Fund and local authorities.
  • Impact management systems — embedding data collection and evaluation into everyday decision-making, so evaluation becomes a habit rather than a report.

Methods and standards

  • HM Treasury Magenta Book — evaluation scoping, design and reporting
  • Theory of change and logic models built with your team, not handed to them
  • Process, impact and value-for-money evaluation, singly or combined
  • Additionality assessment — deadweight, leakage, displacement, substitution and multiplier effects, following the established UK additionality framework
  • Counterfactual design where data allows; contribution analysis where it honestly does not
  • GVA and employment effects estimated on a Green Book-consistent basis
  • Social Return on Investment principles — scope, stakeholders, outcomes, proxies, discounting, sensitivity
  • Outcome monetisation using recognised unit-cost and social-value databases, with proxies disclosed
  • Survey design, sampling and weighting; qualitative interviews with thematic analysis

Where the evidence will not support a claim, we say so in the report. An evaluation that only ever finds success is not an evaluation.


Who it is for

Charities and social enterprises reporting to funders · Councils and public bodies evaluating programmes · Developers and infrastructure projects needing an economic impact assessment · Funders commissioning independent evaluation.


How it works

  1. Agree the questions the evaluation must answer and who will use the findings.
  2. Build or refine the theory of change and indicator set.
  3. Collect and analyse data — surveys, administrative data, interviews, secondary sources.
  4. Quantify outcomes and, where appropriate, monetise them.
  5. Report in plain English, with the tools to keep measuring.
