I strongly recommend that any sensible restaurateur operating multiple fridges and freezers seriously consider investing in the Withnell Sensors temperature-monitoring system.
While there is an initial one-off cost to purchase the system, it very quickly pays for itself. It removes the reliance on staff—often on minimum wage—having to manually log temperatures accurately and consistently, and ensures you always have reliable records available should the Food Standards Agency make an unannounced visit.
In addition, if a freezer or cold room door is accidentally left open, the Withnell system immediately alerts you on your phone if temperatures rise beyond your preset limits.
On three occasions in the past six months alone, the system has prevented potentially significant stock losses. The first incident involved a coolant leak overnight, which stopped all cooling in our walk-in fridge. We were alerted in the early hours of the morning when the temperature rose by six degrees, allowing us to move all stock into other fridges. This intervention saved over £1,800 worth of stock that would otherwise have been lost.
The other two incidents were caused by staff failing to properly shut cold-room doors at the end of a shift—again, issues that were quickly identified before any damage was done.
The most critical moment came during an unannounced visit from the Food Standards Agency. As a business holding a five-star rating, this was not a welcome surprise. The very first thing inspectors asked to see was our temperature records. We were able to show clear, online charts with hourly readings for all fridges and freezers.
After a brief inspection of the rest of the restaurant, they confirmed they were satisfied and that we could retain our current rating. Had our temperature records been incomplete or unreliable, I am confident the inspection would have been far more rigorous.
In short, I cannot recommend the Withnell Sensors system highly enough. I would be more than happy to speak with anyone considering the system and provide a first-hand reference.
