SORP 2026: Why Evidencing Impact Is No Longer Optional

For decades, charity annual reports have told funders, trustees and the public what activity took place: how many workshops ran, how many meals were served, how many calls were answered. From January 2026, that’s no longer enough.

SORP 2026, the new Charities Statement of Recommended Practice, applies to accounting periods beginning on or after 1 January 2026. It requires charities reporting under the SORP to demonstrate, proportionately to their size, the difference their work makes. Not just what happened, but what changed as a result. Larger charities must go further still, reporting how fundraising performed against objectives, including return on funds invested.

This applies to every charity preparing accruals accounts, which includes all charitable companies whatever their income. Smaller charities in that group aren’t exempt, they’re simply held to a proportionate standard. From 30 September 2026, non-company charities in England and Wales with income up to £500,000 can choose receipts and payments accounts instead, which sit outside the SORP, so the first question for many smaller organisations is which basis they report on. The threshold stays at £250,000 in Scotland and Northern Ireland. For charities of any size already stretched by falling donations and rising costs, that raises an uncomfortable question: can we actually evidence our impact, or have we only ever measured our activity?

That’s a question we help charities answer, and it’s worth getting ahead of now rather than at year-end.

A regulatory shift with real teeth

This isn’t a technical accounting footnote. It lands at a moment when:

  • UK giving fell from £15.4bn to £14bn between 2024 and 2025, the first year-on-year fall since 2021. The share of people giving held at 55%, but the average monthly donation dropped from £72 to £65, and there are around six million fewer donors than a decade ago
  • Funders and grant-makers increasingly treat outcome evidence as a condition of funding, not a nice-to-have

Put together, charities are being asked to prove more, often with less money, at exactly the moment funders and trustees are asking harder questions.

How market research closes the gap

Most charities have monitoring data. Far fewer have robust, defensible impact evidence, the kind that stands up in an annual report, a funding bid or a trustee meeting. This is where we spend most of our time with charity clients: turning activity data and stakeholder sentiment into evidence that holds up to scrutiny.

What research providesWhy it matters under SORP 2026
A clear theory of changeTurns activity data into a credible outcomes narrative auditors and funders can follow
Beneficiary voice and outcome measurementProvides the “difference made” evidence SORP 2026 now expects, not just satisfaction scores
Donor and supporter insightExplains why giving is changing (fewer donors than a decade ago, giving smaller amounts on average) so fundraising strategy and reporting align
Proportionate evaluation designMatches the depth of evidence to the size of the charity, rather than over-engineering a small organisation’s reporting burden
Independent, evidence-led narrativeGives trustees and comms teams a defensible story for funders, media and the Charity Commission

The sector’s own guidance talks about “proportionate evaluation”: right-sized evidence, not a compliance exercise. That’s a principle we build into every impact study we design, and it’s usually the first thing we align on with a client before any fieldwork starts, because getting the scale of the evidence right is what keeps the exercise useful rather than burdensome.

Experience that’s already been through this

We’ve spent years working with national health, welfare and hospice charities on exactly this territory. Our work has included patient journey research for Prostate Cancer UK, market and workforce feasibility studies for Anna Freud, brand and awareness research for Epilepsy Action, and donor and campaign research for Hampshire and Isle of Wight Air Ambulance and East Anglian Air Ambulance, alongside work with Independent Age, St Catherine’s Hospice and Citizens Advice. More recently we looked at supporter views for Bath Cats & Dogs Home and profiled the young people most likely to take up sail training for Sail Training International.

That track record means we understand both sides of the SORP 2026 challenge: the methodological rigour needed to produce evidence that holds up, and the practical reality that most charity teams don’t have spare budget or time for anything that isn’t proportionate and directly useful.

Where to start

If your last annual report described what you did rather than what changed, SORP 2026 is a genuine reason to revisit that, not as a compliance chore, but as an opportunity to understand and communicate your impact more clearly than ever.

We can help in a few ways, depending on where you’re starting from:

  • Not sure where your evidence gaps are? We can run a short impact evidence review against SORP 2026’s expectations and tell you plainly what you already have, what’s missing, and what’s actually proportionate to fix.
  • Know you need outcome evidence but not sure how to gather it? We design and run beneficiary and outcome research built around your theory of change, sized to your charity.
  • Reporting season approaching? We can help turn existing data and new research into a narrative trustees, funders and auditors can stand behind.

If any of that would help, we’d be glad to talk it through, no obligation, just a conversation about where you are and what proportionate looks like for you. Email curious@thinkturquoise.com or call 01271 337 100.
