Flu Vouchers for Multi-Site Businesses
Published: August 6, 2026
Last Updated: August 6, 2026

If your business runs from more than one location, a single flu clinic day never covers everyone. Flu vouchers close the gap: staff at any site redeem a pre-paid flu jab at a pharmacy near them, so protection does not depend on which building someone happens to work in. Most multi-site employers we work with end up running both models — an on-site clinic at the largest sites, where there are enough people in one place to fill a session, and vouchers everywhere else. One provider, one invoice, and the whole estate covered. Vouchers are digital, sent by email, redeemable at more than 2,000 UK pharmacies, and valid across the flu season from September to March.
A clinic covers a building. A voucher covers a person. Many multi-site employers need both.
Why one clinic day leaves most of your estate uncovered
On-site clinics work brilliantly where you have enough staff in one building on one day. The trouble is that a multi-site business rarely looks like that. Head office clears the bar comfortably. The regional branch with eleven people does not. Neither does the depot, the satellite office, or the store with staff spread across three shifts.
What tends to happen is predictable: the clinic runs at the largest site, and everyone else is either asked to travel to it or quietly misses out. Asking someone to drive forty minutes for a ten-minute vaccination produces exactly the uptake you would expect. Your coverage ends up concentrated where your clinic was, not where your people are — and the sites with the fewest staff, which are often the hardest to cover operationally when someone goes off sick, end up the least protected.
That matters more than it used to. Since April 2026, Statutory Sick Pay has been payable from the first day of absence, so every flu case now carries a payroll cost from day one. Our guide to the SSP change sets out the arithmetic.

The model most multi-site employers land on
Rather than choosing between a clinic and vouchers, the practical answer is usually to split your estate — running clinics where they suit the site, and vouchers everywhere else. We can run a clinic at any size, so there’s no hard cut-off, but vouchers are often the more practical choice for very small or scattered sites, where filling a session or finding a suitable room on one day is harder to justify.
The advantage of running both through one provider is administrative rather than clinical: a single point of contact, one invoice, and consistent pricing across the estate rather than a patchwork of local arrangements made site by site. We run both models, so the recommendation you get is the mix that actually fits your estate. If you want the fuller comparison of the two approaches, read flu vouchers vs on-site clinics.
What it costs across multiple sites
Voucher pricing is based on your total order, not on how many sites you spread it across — so a business covering nine locations pays the same per voucher as a single-site business ordering the same quantity. For the 2026/27 season, pre-pay vouchers are £23 each for 1–9, £11.50 each for 10–999, and £10.50 each for 1,000 or more. Pay-per-activation is £18.95 per redeemed voucher, with a minimum of 25 activations.
That last option deserves attention if you run a large estate with uneven uptake. Pre-pay is the cheaper unit price, but you pay for every voucher whether or not it is used — and across a spread of sites, uptake is rarely uniform. One region engages enthusiastically, another barely responds. With pay-per-activation you are only charged for vouchers actually redeemed, so quiet sites cost you nothing. There is more on that trade-off, with worked examples, in our full guide to how to buy flu vouchers for your staff.
Pay-per-activation suits estates with uncertain or uneven uptake — you pay only for vouchers that are actually redeemed, so a site that engages poorly does not cost you anything. Pre-pay wins when uptake is high and predictable across the board.
How to roll it out across your estate
A multi-site rollout is mostly a mapping exercise. It takes an afternoon, not a project plan.
- Map your sites and headcount. List every location and how many staff sit at each. This alone usually makes the split obvious.
- Decide which sites justify a clinic. Typically your two or three largest. Everywhere else goes to vouchers.
- Place one order. You order vouchers for the whole estate at once and receive a single redemption code — not a separate order per site.
- Communicate per site. Share the code once, ideally through each site’s own manager rather than one central email that gets lost. Tell people they can use any participating pharmacy, not one specific branch.
- Track and top up. Watch redemption as the season progresses and top up before you run short.
Keeping control across multiple sites
The usual worry with distributing anything across an estate is losing track of it. A few things make that manageable:
- One code, not hundreds. You issue a single redemption code for the organisation rather than managing individual vouchers per person or per site.
- Domain-locked redemption. Access is restricted to your authorised company email addresses, so vouchers cannot leak beyond your organisation — which matters more when a code is circulating across many locations.
- Visible redemption numbers. You can see how many vouchers have been redeemed at any point, so you know your coverage without collecting individual medical records from each site.
- Low-balance alerts. You are notified before the pot runs low, so topping up never becomes an emergency mid-season.
- A full season to redeem. Vouchers are valid from September to March, so sites do not all have to act in the same fortnight. A branch that is flat out in October can pick it up in November.
That last point is the quiet advantage of vouchers across an estate. Clinic days force every site onto your timetable. Vouchers let each site work to its own. It also reduces waste — the longer window means fewer vouchers expire unused, which we cover in the real cost of unused flu vouchers.
Frequently Asked Questions
Can we run an on-site clinic at head office and use vouchers everywhere else?
Yes — many multi-site employers arrange it this way. You get the efficiency of a clinic where you have the numbers, and coverage everywhere else, from one provider on one invoice.
Do we need a separate voucher order for each site?
No. You place one order for the whole organisation and receive a single redemption code to share across every location. There is no per-site admin.
Is there a minimum number of staff for an on-site clinic?
No. We have no minimum numbers, and we run both half-day and full-day sessions — so we can scale a clinic to fit the site rather than the other way round. Tell us your site headcounts and we will tell you honestly which ones are best served by a clinic and which work better with vouchers.
What if uptake is much lower at some sites than others?
That is exactly the situation pay-per-activation is designed for. At £18.95 per redeemed voucher with a minimum of 25 activations, you pay only for the vaccinations your staff actually take up, so a site that engages poorly does not cost you money.
How do staff at each site find a pharmacy near them?
Vouchers are redeemable at more than 2,000 participating pharmacies across the UK, so in most cases there is one within a short walk of the site or of home. Staff can check their nearest branch using our pharmacy finder.
Can staff redeem near home rather than near work?
Yes. The voucher is tied to the person, not the site, so staff can use whichever participating pharmacy suits them — near the office, near home, or near wherever they happen to be that week.
How long do staff have to use their vouchers?
Across the whole flu season, September to March. We would recommend a mid-season reminder to each site so nothing goes to waste.
