UK "Be Ready" Buying Could Lift Sales Without Raising Underlying Demand

The UK’s advice to keep three days of emergency supplies creates a forecasting problem before it creates a proven inventory shortage. Retailers must distinguish households buying products earlier from households consuming more of them. Treating both signals as lasting growth could leave replenishment orders arriving after the initial buying has subsided.
The government launched its updated Be Ready campaign on October 22, encouraging households to prepare gradually. For supply-chain teams, the immediate question is whether sales patterns justify changing orders, product availability or inventory assumptions, and how those decisions would hold up if a disruption also disabled planning systems.
A preparedness message is not yet a demand forecast
EJ Tavella, Executive Vice President, Intelligent Applications, Anaplan, said the planning software company had not yet seen demand changes that would justify adjusting forecasts or stock levels. That observation has limits: it is not a market-wide retail sales assessment. It nevertheless argues against assuming that a public preparedness campaign automatically warrants a general increase in inventory.
The government’s checklist reinforces the distinction. Households are encouraged to check existing supplies and acquire missing items during regular shopping trips. It includes long-life food that needs neither refrigeration nor cooking, alongside water and other essentials. Following that advice could change the timing and composition of purchases without producing an equivalent increase in ongoing consumption. “In either case, planners need to know if people are buying more or simply buying earlier,” Tavella said. “Mistaking a temporary spike for lasting growth leads to excess stock, markdowns and waste once demand settles.”
For replenishment teams, the implication is to distinguish a temporary increase in household stocks from the recurring purchases needed to replace what households consume. A short period of higher sales may justify a near-term response without supporting a permanent increase in the baseline forecast.
The assortment can change before total demand does
Tavella identified another risk: preparedness purchases may concentrate on products that normally sit at the edge of an assortment. Long-life and ready-to-eat ranges could face pressure even if overall category sales provide little evidence of change. That creates a potential mismatch between aggregate forecasting and item-level availability. A category can appear adequately stocked while the particular products customers want become scarce. If shoppers then switch to alternatives, sales of those substitutes may also become harder to interpret.
Tavella recommends separate scenarios for gradual stock-building and a sudden surge. The former requires monitoring small, sustained increases and adjusting replenishment carefully. The latter requires testing stock availability, supplier responsiveness, distribution capacity and substitution when preferred products sell out.
These scenarios support different decisions. A gradual shift may allow buyers to adjust order quantities within existing supply arrangements. A sharp surge may require allocation choices before additional stock can arrive. Neither scenario, by itself, establishes that consumers will sustain the higher purchasing rate.

Availability depends on location as well as quantity
A national stock position also cannot establish whether the right products are accessible where demand changes. In earlier coverage by The Supply Chainer on retail peaks, Shibu Sasidharan, Senior Vice President of Strategy and Growth, Exol, highlighted that limitation: “You can have plenty of stock available, but if it’s sitting hundreds of miles from where customers are placing orders”.
His observation concerned promotional peaks, rather than the Be Ready campaign, but the inventory-placement problem is relevant. An increase concentrated in particular locations or product ranges can create replenishment pressure despite adequate stock elsewhere in the network.
The analytical consequence is that planners need to examine sales alongside local availability. A fall in sales after a spike could indicate that households have finished building their supplies. It could also reflect an empty shelf. Those interpretations lead to different purchasing decisions, making stockout information important when deciding whether an apparent surge has ended.
Fallback planning needs decision rules, not just backup data
The preparedness question also extends to how replenishment continues when systems become unavailable. Tavella recommends agreeing in advance which products, locations and customers take priority, and maintaining secure, regularly updated offline copies of essential inventory data, outstanding orders and replenishment plans. Those records provide a starting point, but teams also need to understand the logic normally applied by automated workflows. Tavella argues that staff should practise making those decisions manually before a disruption, while retaining a record of what was decided and why.
The operational responsibility therefore extends beyond producing a revised forecast. Planning, purchasing and distribution teams need a shared basis for deciding whether a demand signal merits additional stock, where that stock belongs and who can change allocations during an outage. Without that agreement, an organization may preserve its data yet lose the ability to turn it into consistent replenishment decisions.
