The 25p That Was Always There

An estimated £560 million in Gift Aid goes unclaimed by UK charities every single year. The donors are eligible. The money is there. Something keeps getting in the way.

 

A problem hiding in plain sight

Gift Aid is one of the most straightforward ways a charity can increase the value of every donation it receives. For every £1 given by an eligible UK taxpayer, the charity can claim an additional 25p from HMRC at no cost to the donor. It requires nothing extra from the supporter and no additional fundraising. It is simply money that is already there, waiting to be claimed.

And yet research suggests that around £560 million goes unclaimed every year. The reasons are well documented. Donors forget to complete declarations, or never quite understand that they need to opt in at all; around a quarter of eligible donors are unaware of how the scheme works. Charities struggle with the administrative complexity of tracking declarations and maintaining compliance. And in the fast-moving environment of a live campaign, asking someone to stop and fill in a form often means they don't fill it in at all.

The result is a significant and largely invisible income gap. Not a failure of generosity on the donor's part, and not a failure of intent on the charities'. Just a process problem that, with the right infrastructure, is entirely solvable.

The text donation problem that took years to fix

For charities running text donation campaigns, the Gift Aid problem had an additional layer. Even when a donor was willing to make a declaration, claiming Gift Aid on a text donation wasn't possible for a long time. The reason was technical rather than regulatory. HMRC requires every Gift Aid declaration to be tied back to the exact donation it belongs to, with a clear audit trail. Mobile networks didn't provide the level of detailed reporting needed to satisfy that requirement, which meant charities were effectively locked out of claiming Gift Aid on text donations entirely.

Cymba solved that problem by building a Gift Aid declaration service that generates a unique, secure link tied to each individual donation. Once the donation is confirmed, Cymba texts the donor a link that takes them to a simple declaration page where they can complete their Gift Aid consent in seconds. Every declaration is traceable back to the original gift, the audit trail is complete, and HMRC's requirements are satisfied.

The moment matters

There is a reason Cymba sends the Gift Aid link after the donation rather than during it. Asking someone to stop mid-giving to fill in a form interrupts the moment at exactly the wrong time. The supporter is primed to give, and introducing an administrative step before the donation is confirmed is one of the most reliable ways to lose it.

By waiting until the giving is done, the dynamic shifts entirely. The supporter has already acted. They're in a good place. A text arriving to say thank you, with a simple link to make their gift go further, feels like a natural next step rather than an interruption. In that moment, completing a Gift Aid declaration takes seconds, and most supporters who receive the link will follow it.

That timing is not an accident. It is a deliberate design decision, built around how donors actually behave rather than how charities would find it most convenient to ask.

One journey, two jobs done

The secure link takes the donor to a CymbaPages declaration page, a fully branded, mobile-optimised form that works on any device without an app or login. It is customisable to reflect the charity's own identity, so the experience feels like a natural continuation of the giving journey rather than a handoff to a generic third-party form.

And while the donor is there, communication preferences are captured at the same time. Gift Aid consent and GDPR-compliant contact preferences in a single short interaction, with no need for a second conversation, a follow-up email, or a separate data collection exercise. One journey, two jobs done properly.

Secure by design

A Gift Aid declaration carries real financial and personal information, and Cymba treats it accordingly. Every link generated is unique to a single donation, time-limited to reduce fraud risk, and tied to one donor rather than accessible from a generic URL. Royal Mail address validation is built in, catching errors before they create compliance problems downstream.

The result is a declaration process that is as secure as it is simple.  Both for the charity managing the data and the supporter trusting their information is being handled properly.

Proof at scale

When the 2020 Poppy Appeal faced the sudden loss of its traditional in-person collection infrastructure, the Royal British Legion needed to adapt quickly. Cymba's mobile Gift Aid collection gave the charity a way to capture eligible declarations by text at exactly the point donors were already giving, recovering income that would otherwise have gone unclaimed during one of the most challenging fundraising periods in the charity's history.

The campaign demonstrated something important: that mobile Gift Aid works not just in ideal conditions, but under real pressure, at scale, when it matters most.

The 25p is still there

For every charity running text donation campaigns without Gift Aid in place, the arithmetic is straightforward. Every eligible donor who gives without a declaration is leaving 25p on the table. Over a busy campaign season, that adds up to a significant income stream sitting unclaimed.  The infrastructure to claim it has existed for years. The question is whether it is in place before the next campaign goes out.
