One-off volunteering: how Little Village turned a pilot into a core programme
In short
One-off volunteering works best with a simple standalone task, light onboarding and a small pilot that lets staff see the benefit, Little Village’s volunteering team explained. From January to April 2025, 263 of 357 people who booked attended, and at least 15 later became regular volunteers without a deliberate conversion journey.
In this Lunch and Learn, Calleigh-Marie, Director of Volunteering, and Daniela, Volunteer Recruitment Manager, shared how Little Village, a network of baby banks supporting families with children under five across London, piloted one-off volunteering days and made them a key part of how the charity involves people.
Key points
One-off volunteering works best with a simple, standalone task that needs no experience.
Make it easy to sign up, and people are far more likely to show up.
Start with a small pilot and let staff who’ve seen it work win over their colleagues.
Schedule sessions for when you need extra hands, so they add capacity rather than workload.
One-off volunteers can become regular volunteers, donors and advocates, so plan how to stay in touch.
Watch the full session below, including how they handled early tension with regular volunteers and their plans for family volunteering days. Under the video, we’ve summarised the key takeaways.
Why offer one-off volunteering?
After the pandemic, Little Village saw more no-shows and fewer people able to commit to a rota because of work, childcare or busy lives. One-off days gave them a flexible, low-commitment way in, and let the charity bring in help exactly when it needed it.
Design a role people can do straight away
Little Village split its catch-all on-site role in two. Baby bank helpers work with families, so they need fuller training and supervision. Pick and pack volunteers sort, check and pack donations: if you can clean a pair of shoes or spot a stain, you can do it. Look for low-risk, high-value tasks that stand on their own.
Keep onboarding for one-off volunteers light
One online form: contact details, an emergency contact, health conditions and how they heard about you.
A template confirmation email with details of the day, the site and the volunteer handbook.
A briefing on one task, not everything about how the site runs.
A clear message: no experience needed, just enthusiasm and comfy shoes.
Getting staff and regular volunteers on board
Staff worried about being overwhelmed by untrained groups, so the pilot ran at the smallest site with small groups, framed as a test. Once staff saw the extra help, they championed it to other sites, which worked far better than a message from head office. Calleigh’s one regret was not introducing the idea to regular volunteers sooner. Success stories and buddying roles for experienced volunteers soon won them round.
Decisions to make early
Age: a minimum of 14, with an accompanying adult and set adult to under-18 ratios for groups.
Corporate groups: paying corporate teams get an exclusive session, while one-off volunteers join mixed groups on dates the charity chooses.
Returners: welcome back as often as they like, with a light-touch route into regular volunteering.
Policies: decide how your policies, including support for additional needs, apply to people you know less about.
Promoting one-off volunteering and measuring the results
Once the model was proven, Little Village promoted it through flyers, its website, local volunteer centres and university portals. Little Village told us most people found the sessions through an internet search, followed by word of mouth at work and Instagram. They also told us that from January to April 2025 they ran 30 sessions, and 263 of the 357 people who booked came along: about 73%. The ripple effects went further, with volunteers offering professional skills, pro bono support and donations from their employers.
Do one-off volunteers come back?
Of the 357 people who booked, Daniela said at least 40 to 50 had returned for more one-off sessions and at least 15 had become regular volunteers, all without a deliberate conversion journey.
Running one-off sessions in Volunteero
In Volunteero, you can set up one-off sessions as shifts with capacity limits, and check-in and check-out, including by QR code, records attendance and hours. That data feeds straight into your reports and dashboards, with no manual tallying. Book a demo to see how it works.
