If you transport temperature-sensitive goods — from medicines to certain foods — your biggest operational risk isn’t just keeping a fridge unit running. It’s being able to prove conditions stayed within the required range throughout a journey, and knowing quickly when something goes wrong.
A well-known UK example is AAH Pharmaceuticals, which introduced temperature-controlled Ford Transit conversions with live temperature monitoring and reporting as part of a wider fleet refresh (reported in late 2015 and early 2016, with rollout plans running to the end of 2017).
Why temperature monitoring matters (beyond “cold van = job done”)
For refrigerated medicines, UK good distribution practice (GDP) expectations focus on maintaining labelled storage conditions during transport, using calibrated monitoring, retaining data, and having procedures for deviations and corrective action.
In plain terms: it’s not enough to have refrigeration — you need control, monitoring and records that stand up to audits and investigations.
What AAH’s approach looked like (and the useful lesson)
Trade reports described AAH’s fleet refresh using temperature-controlled Ford Transit conversions, with a telematics temperature system (described as a Seven “transcan” unit linked to the Seven Eye website) so drivers and operations teams could monitor temperatures and access reporting.
The point for other operators isn’t the brand of kit — it’s the principle:
- Real-time visibility (so issues are spotted early)
- Automatic logging (so you have an auditable trail)
- Clear response steps (so staff know what to do when alerts happen)
A practical UK checklist for temperature-controlled van operations
Use this as a starting point whether you’re running one van or a fleet.
1) Define the temperature requirements by product
- Document the required range (for medicines, follow the product labelling / specification and your quality procedures).
- Separate “refrigerated” vs “controlled ambient” loads where relevant, and plan routes accordingly.
2) Validate your vehicle setup for real-world delivery work
- Pre-cool where needed, and confirm the load space reaches temperature before loading (and stays stable during multi-drop stops).
- Make sure internal airflow isn’t blocked by packaging or overloading.
3) Monitor properly: calibrated probes, continuous records, retained data
GDP guidance highlights the value of routine temperature monitoring, calibrated devices, reviewing the data, and keeping records.
- In-vehicle sensors/probes and a system that logs throughout the journey
- A process for reviewing journey data and recording corrective actions for excursions
4) Set clear “temperature excursion” procedures
- Who gets alerted and when
- What the driver should do at the roadside/depot
- How you quarantine/assess affected stock and record the outcome
5) Train drivers for temperature integrity (not just driving)
Include simple habits that protect temperature stability, such as:
- Minimising door-open time
- Using internal curtains/partitions correctly (if fitted)
- Reporting unit faults immediately and following the excursion process
6) Security, claims evidence and insurance implications
If you carry high-value or regulated goods, think through the knock-on risks:
- Goods-in-transit and liability: check what your contracts say about temperature breaches and evidence requirements.
- Vehicle insurance: declare the correct use (e.g., courier/haulage, own goods, pharmaceutical distribution) and list any major conversions where your insurer requires it.
- Incident documentation: a temperature log plus delivery timestamps can support investigations if a load is disputed.
The takeaway
AAH’s fleet refresh is a useful reminder that “refrigerated” isn’t the same as “controlled”. For many operators, the win comes from monitoring + records + response, because that’s what turns a cold box on wheels into a defensible, auditable transport process.
