When stock starts appearing in walkways and every incoming delivery causes a reshuffle, a bigger warehouse can seem like the obvious next step. Sometimes it is. But a crowded building can also be a sign that goods are arriving at the wrong time, products are stored badly or too much space is occupied by items awaiting a decision.
Warehouse and supply chain specialists such as ASCALi work across inventory, layout and operating processes. Those are useful areas for any business to examine before committing to a move. Establish what is filling the space, where work slows down and whether the problem lasts all year.
Separate a storage shortage from a processing bottleneck
A warehouse has to hold goods and move them through receiving, storage, picking, packing and dispatch. Capacity in one part does not guarantee capacity elsewhere.
Take a wholesaler with free racking but pallets waiting beside its receiving doors. If those pallets have not been checked and booked in, extra storage positions may achieve little. The immediate constraint could be the receiving team’s workload or missing delivery information.
For a working week, record where queues form and how long goods wait. Follow several orders from arrival to dispatch. Ask staff what prevents the next task from starting. These observations help distinguish a shortage of usable storage from delays that leave products stranded between stages.
Count the space the operation needs to function
An empty patch of floor is not automatically spare storage. People, vehicles and handling equipment need room to move, and access routes must remain usable.
The HSE’s warehouse safety guidance explains the importance of suitable traffic routes and separating pedestrians from vehicles. Treat those requirements as part of the layout assessment, rather than space to squeeze when stock builds up.
Draw a simple plan showing storage, receiving, packing, dispatch, returns and movement routes. Mark where temporary pallets repeatedly appear. If an area is used every afternoon to prepare collections, it needs to be included in the working layout even when it is empty during the morning walk-round.
Give waiting stock an owner and a deadline
Returned goods, damaged cartons, discontinued products and stock awaiting inspection can occupy space long after anyone remembers why they were put there.
Review these groups separately from stock available for sale. Record the quantity, location, reason for holding it, person responsible and next decision date. Keep genuine quality holds separate until the appropriate person releases them.
For example, a returned product may need a replacement box before it can be resold. Another may require a supplier’s authorisation to send it back. Giving each item a specific next action is more useful than repeatedly moving the same pallet out of the way.
Check how products are positioned
A layout that suited last year’s orders may no longer fit today’s business. More small orders, a broader range or a new bulky product can change the work without a dramatic rise in sales value.
Look at how often each product is picked, the quantity taken per order and how often its picking location needs refilling. Frequently picked items should be assessed for accessible positions, alongside weight, handling and compatibility requirements.
Consider a small picking shelf that needs replenishing six times a day. Increasing its allocation might reduce interruptions. Giving the same extra space to a product picked once a fortnight would have a different effect. Trial changes in one area and compare travel time, replenishment work and errors before extending them.
Examine when vehicles arrive and leave
Two large deliveries arriving together can create a temporary space problem even where the daily volume is manageable. Similarly, completed orders may sit for hours because everything is prepared long before the carrier collects.
The HSE’s guidance on loading areas stresses the need for adequate room around bays for safe vehicle and pedestrian movement. That makes arrival and collection patterns relevant to capacity, as well as convenience.
Plot arrivals, departures and waiting stock by hour. Discuss whether suppliers can use more suitable delivery windows and whether dispatch work can be scheduled around collections. Check the effect on labour and customer deadlines before changing either.
Test the improved layout against future demand
Once avoidable congestion is understood, assess the remaining capacity against realistic growth. Use units, pallets, order lines and handling requirements as well as turnover. Revenue growth alone does not describe the warehouse workload.
Compare an ordinary week, a busy week and the expected peak. Include time for replenishment and the space needed while goods move between tasks. A seasonal overflow arrangement may deserve consideration, but include extra handling, transport and stock visibility in its cost.
A move becomes easier to justify when the evidence shows exactly what the current site cannot accommodate. That might be more storage, additional loading access or room for packing. Start property discussions with those requirements, and the next building is more likely to solve the problem that prompted the search.
