Flu Vouchers vs On-Site Clinics: Which Is Right for Your Workforce?
Published: June 27, 2026
Last Updated: June 27, 2026
When you organise a workplace flu programme, the first real decision is how to deliver it: bring a clinic to your office, or give staff vouchers to redeem at a pharmacy. Both are good options. They just solve different problems, and the right choice depends far more on how your workforce is shaped than on which one is “better” in the abstract.
This guide is a practical decision framework: where each option is strongest, the uptake trade-off between them, and why a lot of employers end up using both. For the full detail on how vouchers work and what they cost, see our complete guide to corporate flu vouchers.
AT A GLANCE
- On-site clinics suit concentrated, single-site teams and tend to drive higher same-day uptake
- Vouchers suit remote, hybrid, multi-site and smaller teams
- The deciding factor is workforce shape, not headcount alone
- Many employers run both — a clinic at HQ, vouchers for everyone else
How each one works
An on-site clinic brings a pharmacist-led team to your premises for the day. Staff are vaccinated at work, often in minutes, with no travel and nothing to arrange themselves. A voucher programme works the other way round: each employee gets a digital voucher and redeems it at a participating pharmacy near home or work, at a time that suits them.
Where on-site clinics are the stronger choice
On-site clinics come into their own when your people are in one place. The convenience is the whole point — when getting vaccinated means stepping away from your desk for a few minutes, far more people do it. There is a visible, social element too: when colleagues are getting their jab, others follow. For a concentrated workforce, an on-site day usually delivers the highest uptake of any option, and it does it fast.
On-site is the natural fit when most of your team is at a single site on a predictable day, when you have the numbers to fill a clinic, and when you want the programme done and dusted in one visit.
Where vouchers are the stronger choice
Vouchers exist for the workforce a single clinic cannot reach. If your people are remote, hybrid, spread across several sites, or simply too few to justify a clinic, a voucher lets every one of them get protected locally without anyone being left out because they were not in the office that day.
Vouchers are the natural fit for remote and hybrid teams, multi-site businesses, smaller headcounts with no minimum to meet, and any situation where “everyone in one room on one day” is never going to happen.
The uptake trade-off
This is the honest tension between the two. On-site clinics generally achieve higher uptake, because vaccination is frictionless and visible — the decision is made for people by sheer convenience. Vouchers ask the employee to take an extra step in their own time, and some never get round to it, which is where unredeemed vouchers come from.
But that higher on-site uptake only counts for the people who can actually attend. A clinic that vaccinates 80% of head office does nothing for the third of your team working from home. Vouchers trade a little redemption friction for total reach. The best delivery method is the one that reaches your particular workforce — which is exactly why many employers stop treating it as an either/or.
A quick decision framework
| Your workforce | Usually the better fit |
|---|---|
| Mostly in one office, 50+ people | On-site clinic |
| Remote or hybrid, spread out | Vouchers |
| Several smaller sites | Vouchers — or on-site at the largest site plus vouchers elsewhere |
| Small team (under ~25) | Vouchers |
| A central HQ plus remote staff | Both — clinic at HQ, vouchers for the rest |
You don’t have to pick just one
Plenty of employers get the best of both: an on-site clinic on the busiest day at the main office to capture high uptake where people are concentrated, and vouchers for remote workers, smaller satellite offices and anyone who misses the clinic. The point is reach plus convenience, not loyalty to a single method. Because we run both services in-house, you can cover an entire mixed workforce through one pharmacist-led provider rather than stitching two suppliers together.
What about cost?
The two are priced differently, so a straight per-head comparison can mislead. On-site clinics are quoted on your team size and locations; vouchers are priced per unit, either bulk pre-pay or pay-per-activation. The full breakdown — including how to work out which voucher model is cheaper for your expected uptake — is in the vouchers guide.

Frequently asked questions
Are on-site clinics or vouchers better for uptake?
On-site clinics usually achieve higher uptake among people who can attend, because vaccination is convenient and visible. Vouchers reach dispersed staff a clinic cannot, even if redemption needs a nudge. The better option depends on how concentrated your workforce is.
Can I run an on-site clinic and vouchers together?
Yes — it is a common and effective setup: a clinic at your main site plus vouchers for remote, hybrid and satellite staff, all through one provider.
Is there a minimum team size for an on-site clinic?
On-site clinics work best with enough people to fill the day. For smaller or scattered teams, vouchers are usually the more practical and cost-effective route, with no minimum headcount.
