Most event organisers spend a lot of time thinking about how to find volunteers and very little time thinking about how to keep them. That's a mistake. Recruiting a new volunteer costs time, effort, and often money. Retaining one who already knows your event, understands their role, and is reliable costs almost nothing. This guide covers what keeps volunteers coming back year after year.
Why retention matters more than recruitment
Experienced volunteers are worth significantly more than new ones. They know the site. They know the roles. They need less briefing, make fewer mistakes, and often step up to help others without being asked. When a returning volunteer arrives on event day, you breathe slightly easier.
New volunteers, by contrast, require investment. You need to explain everything from scratch, monitor them more closely in the early part of their shift, and accept that first-timers are more likely to no-show or arrive late.
Research across the voluntary sector consistently shows that the cost of replacing a volunteer — in recruitment time, briefing time, and reduced performance — is significant. Even modest improvements in retention compound quickly. If your event uses 50 volunteers and you improve year-on-year retention from 50% to 70%, that's 10 fewer people you need to recruit, onboard, and brief each time.
The good news is that retention is almost entirely within your control. People don't stop volunteering because they got bored of events. They stop because they felt undervalued, uninformed, or like their time was wasted.
The experience on the day is everything
Volunteers decide whether they are coming back while they are still at your event. The decision is almost always made by lunchtime. Everything that happens in those first few hours — whether they felt welcomed, whether they knew what to do, whether their team lead was organised — shapes whether they say yes when you ask them next year.
The basics that volunteers care most about:
- →Arriving to a clear briefing and a welcome — not confusion about where to go or what to do
- →A team lead who knows their name and is available if they have questions
- →Feeling like their role matters — context about the event and why their contribution is important
- →Adequate breaks, food and water, and shelter if the event is outdoors
- →Not being left standing around with nothing to do — gaps in activity are demoralising
The things that kill retention most reliably are: feeling invisible, being given unclear or constantly changing instructions, not being fed or looked after, and finishing the day with no acknowledgement of what they contributed.
None of this requires budget. Most of it requires someone with good people skills in a team lead role and a bit of advance planning.
Tip
Brief your team leads on the importance of their role in volunteer experience — not just task management. A team lead who checks in with their volunteers and says thank you at the end of a shift makes a measurable difference to retention.
Say thank you — and mean it
A thank-you email sent within 48 hours of the event is one of the highest-return actions you can take. It costs almost nothing and makes a disproportionate impression.
A good post-event thank-you:
- →Is personal — use their name, mention their specific role
- →Acknowledges the specific contribution ("the registration desk ran without a hitch because of the team you were part of")
- →Shares a result or outcome if you have one ("we raised £8,000 for the club" / "230 finishers crossed the line")
- →Is warm and genuine, not corporate
- →Ends with a forward-looking note — even just "we hope to see you next year"
What to avoid: a generic mass email that reads like it was written by a committee, sent a week later. People can tell when they are one of 200 BCC recipients of a formulaic message, and it leaves a worse impression than no message at all.
Beyond the email, consider: a social media post naming and photographing your volunteer team (with permission), a mention in your club newsletter, or a small thank-you gift for those who gave significant time. None of these need to be expensive — recognition of effort is the point, not the monetary value.
Tip
Keep a record of who volunteered in which role each year. When you write your thank-you, being able to reference what someone specifically did shows you actually noticed.
Ask for feedback — and act on it
Asking volunteers for feedback does two things. It gives you genuinely useful information about what to improve. And it signals to the volunteer that their opinion matters, which makes them feel valued.
A short feedback form sent alongside the thank-you email works well. Keep it to 5–8 questions maximum and include at least one open question ("what one thing would you change?"). The open questions are almost always more useful than the ratings.
The critical step that most organisers skip: do something with the feedback, and tell your volunteers you did. Even a brief "based on your feedback last year, we've changed X" in your next round of volunteer communications closes the loop and proves you were listening.
Volunteers who feel heard come back. Volunteers who fill in a form and never see any result stop filling in forms — and often stop coming back too.
Stay in touch between events
One of the most effective retention tactics is also one of the least used: staying in contact with your volunteers between events. Not frequently, and not with sales messages — just enough to maintain the relationship.
What works:
- →A short update 2–3 months after the event sharing outcomes (how much was raised, results, photos)
- →An early-access announcement when the next event date is confirmed ("as one of last year's volunteers, you hear this first")
- →A genuine message at Christmas or New Year if your event has a strong community feel
What doesn't work: adding volunteers to a general email newsletter without asking, or only contacting people when you need something from them.
The goal is to make volunteers feel like they are part of something, not just a resource you draw on once a year. Events with strong volunteer communities — where people know each other and feel connected to the organisation year-round — consistently have higher retention than those that go silent after pack-down.
Tip
A simple spreadsheet or a tool like EventRota that holds your volunteer history makes it easy to identify returning volunteers and give them early access or recognition.
Give returning volunteers more responsibility
People who have volunteered at your event once and come back are telling you something. They liked the experience enough to do it again. That's valuable information — and those are the people you should be investing in.
For returning volunteers, consider:
- →Promoting them to team lead roles — they know the event and can brief newer volunteers
- →Asking for their input on how the previous event ran and what could be improved
- →Giving them first choice of role or shift so they can shape their own experience
- →Involving them in planning discussions, even informally
This creates a progression pathway — new volunteer → returning volunteer → team lead → senior volunteer or committee member. Each step deepens someone's investment in your event and makes it significantly harder to imagine not being involved.
Events that develop volunteer leaders from within their own ranks consistently outperform those that rely on organisers to manage everything directly. It's also more sustainable — as your event grows, you have experienced people who can carry responsibility rather than everything funnelling back to one or two overloaded organisers.
Build a volunteer community, not just a list
The most resilient volunteer programmes are built around a genuine community — a group of people who enjoy each other's company and feel connected to a shared purpose, not just a roster of names who show up when asked.
Community builds naturally when:
- →Volunteers are briefed together rather than arriving to individual role stations
- →There is a shared space (tent, room, table) where volunteers can gather between shifts
- →Social elements are built in — even just a post-event drink or a team photo
- →Volunteers from different roles get to interact, not just work in their own isolated zone
- →The organising team is visible, approachable, and shares in the team's experience rather than sitting apart
Online, a private Facebook group or WhatsApp group for your volunteer team gives people a place to stay connected and see photos from the event. It feels informal, but it builds the sense of belonging that makes people come back.
Ultimately, what retains volunteers is the same thing that retains any group of people in any context: feeling like they matter, feeling like their time was well spent, and feeling connected to something they care about. Get those things right, and recruitment becomes a much smaller problem.
