A prescription can leave the dispensary correctly labelled and still turn up two days late, damaged, or at the wrong address, and very little of that is really about the courier van. It is about whether anyone ever wrote down what "on time" means for that item, tracked why deliveries fail by cause rather than by complaint, and gave someone the authority to fix a broken route before it becomes a pattern.
The last mile is where good pharmacy operations quietly fail
Clinical governance and dispensing accuracy get most of the attention in a UK telehealth build, and reasonably so: they carry the regulatory weight. But the part the patient actually experiences is the parcel arriving, and that leg is often left to whatever courier account a wholesaler or dispensing partner happens to already hold, rather than something an operator has deliberately chosen and specified.
Dispatch cut-off times are only half of the promise a service makes; see our piece on same-day dispatch logistics for that side of the timeline. The courier leg that follows is where the promise is either kept or quietly broken, usually without anyone in the business noticing until a complaint lands.
The failure modes that actually show up
In our observation, delivery failures for prescription medicines cluster into a handful of repeat categories rather than one-off bad luck. Naming them is the first step to fixing them.
- Missed collection cut-offs that quietly turn a same-day promise into next-day, or later
- Access failures at flats, concierge buildings, or rural drop points, with no agreed fallback
- Temperature-sensitive items, such as GLP-1s or biologics, left outside the cold-chain window on a doorstep
- No proof-of-delivery capture, so a "delivered" status cannot be checked against a patient dispute
- Signature-on-delivery rules applied inconsistently for controlled or higher-risk items
Each of these is a process gap rather than a courier simply being unreliable, and process gaps can be closed with a written SLA and someone actually monitoring it.
What to evaluate before signing a courier contract
Price and headline speed are the easiest things to compare between couriers, and the least useful. A named account manager, real-time tracking API access, a defined escalation path outside a generic support inbox, and evidence the courier understands pharmaceutical handling matter more once volume grows. See our guide on choosing a UK dispensing partner for the wider due-diligence list this sits inside.
Ask what their on-time and first-attempt success figures actually mean and how they are calculated, rather than accepting a single headline number without a definition attached. A rate measured against "attempted" deliveries reads very differently from one measured against everything dispatched.
A courier SLA without a shared definition of "on time" and a named escalation contact is not a service level: it is a hope.
An SLA needs a shared definition of "on time", not just a target
A workable SLA specifies the collection window, the transit time by postcode band, the first-attempt success rate, the proof-of-delivery method, and the escalation timeframe when something goes wrong. Without all five written down and agreed by both sides, "on time" is whatever the courier says it is after the fact.
This is not only a commercial concern. MHRA's Good Distribution Practice guidance sets expectations around traceability and record-keeping for medicines in transit, and GPhC standards for registered pharmacies require that patients receive their medicines safely, so the SLA has to serve the regulatory record as well as the delivery promise.
Proof of delivery, and the cold-chain question
Photo, signature, geotag and timestamp capture at the point of delivery matter for disputes; without them, a "my prescription never arrived" complaint is unresolvable in either direction, which is expensive for the operator and unsatisfying for the patient.
For temperature-sensitive dispensing, see our piece on cold-chain dispensing, the SLA also needs to specify insulated packaging standards and a delivery window that avoids a parcel sitting in a hot van or on a step for hours before anyone collects it.
"On time" means nothing until both sides agree what it is measured against.
What happens after a delivery actually fails
The test of an operations team is not whether deliveries ever fail; some always will. It is whether there is an agreed workflow for what happens next, rather than each failure being handled ad hoc by whoever picks up the ticket.
- Log the failure against a specific cause code: missed cut-off, access issue, damage, or no proof of delivery captured
- Contact the patient within an agreed same-working-day window, not after they chase
- Offer redispatch, refund, or both, depending on item type and clinical urgency
- Feed the cause code back into the courier scorecard, not just the individual support ticket
- Flag repeat failures at the same address or route to the superintendent pharmacist for review
Packaging plays a part here too; our guide to packaging and tamper-evidence covers how damage and tampering disputes get resolved once a parcel is in question.
How this fits into PExpo's dispensing layer
PExpo's regulated dispensing partners operate within Good Distribution Practice-aligned processes, and clinics and brands get visibility into dispatch and delivery performance rather than a black box they only hear from when something goes wrong.
For groups running more than one site, this gets more complicated again; our piece on multi-location dispatch coordination covers what changes at that scale. Either way, the point of sitting behind a regulated platform is not having to build and police courier contracts alone.
Courier and SLA management will never be the most interesting line in a UK telehealth operator's plan, but it is one of the few that patients notice every single time. Pair it with the operational basics covered in our guides to same-day dispensing and out-of-hours cover, and it stops being a source of complaints and starts being a quiet advantage. If you would rather not build and manage that layer yourself, see how PExpo works for clinics.
Frequently asked questions
What is a reasonable delivery SLA for UK telehealth medicines?
There is no single industry-wide figure, and the right target depends on the item type, cold-chain needs, and the delivery window set at checkout. What matters is that the SLA defines the collection cut-off, transit window, first-attempt success rate, and proof-of-delivery method in writing, rather than relying on an aspirational headline number from the courier.
Who is responsible when a courier loses or damages a prescription medicine?
Contractual liability for the parcel usually sits with the courier under the terms agreed, but regulatory responsibility for safe supply sits with the dispensing pharmacy and its superintendent pharmacist under GPhC standards. Operators should agree the liability, replacement, and patient-communication process before an incident happens, not while one is unfolding.
Does a courier handling prescription medicines need to follow Good Distribution Practice?
MHRA's Good Distribution Practice guidance governs the wholesale distribution of medicines, including transport and storage conditions, and applies to how prescription items move once they leave the dispensary. Any courier handling prescription medicines, especially cold-chain items such as GLP-1s or biologics, should be assessed against GDP-relevant handling standards rather than treated as a generic parcel courier.
