Self-storage.
Self-storage generates far fewer trips than most commercial uses. We show that clearly and make sure vans and trailers can load safely.
Main guide: Transport Statements
Customers visit self-storage occasionally, often with a van or trailer. The evidence is usually short, focusing on trip rates, loading and access.
What the council focuses on
The number of trips compared with other employment uses, access and turning for vans and trailers, loading arrangements and parking.
The evidence that answers it
- Trip generation from comparable self-storage sites.
- Swept paths for vans and cars with trailers.
- Loading bay and parking layout.
- A comparison with the existing or permitted use.
Container sites
Outdoor container storage needs room for container deliveries on lorries and for customers to reach their units. We check the layout for both.
What the application usually needs
- A Transport Statement showing low trip generation.
- Access design for cars, vans and removal lorries.
- Parking and loading bays at the building.
- Swept paths for the largest vehicles.
- Comparison with the existing use.
A typical case
A typical case is a self-storage building replacing a vacant warehouse. The council asks about traffic and parking. We show from TRICS that self-storage generates far fewer trips than most commercial uses, design loading bays at the entrance for vans and removal lorries, and show a net reduction compared with the warehouse.
Technical points
Self-storage visits are spread across the day and week, with modest peaks at weekends. Customers often hire vans, so bays and swept paths should allow for larger vehicles. Container storage yards need space for container deliveries and customers moving goods.
Many self-storage operators publish typical customer numbers per thousand square metres, and TRICS includes surveyed sites. Visits are short, often with a hired van or trailer, so we size the loading area for the vehicles customers actually use. Where a scheme includes business storage or a trade counter, we add those trips and any deliveries to the assessment.
If highways raise concerns
Objections to self-storage are uncommon, because trip generation is low. Where concerns arise, they usually relate to the access for larger vans and removal lorries.
Swept paths and a clear comparison with the existing use usually resolve them quickly.
How we help
We prepare a short transport statement and layout checks.
The same questions arise in Scotland and Wales, where they are assessed against NPF4 and Scottish guidance or Planning Policy Wales and TAN 18 rather than the NPPF.

Questions we get asked
Does self-storage generate much traffic?
Very little compared with most commercial uses. TRICS has data for comparable sites.
Do I need a Transport Statement?
Often a short statement or note is enough.
How many parking bays are needed?
Enough loading bays at the entrance for the busiest periods, usually weekends.
Can container storage work on a small site?
Yes, with space for container deliveries and customer access.
Will the council compare with the existing use?
Yes, and the change is often a reduction.
