If you’re thinking about opening a self storage facility in the UK, one of the first questions to ask is: do I need planning permission?

The short answer is: yes, in most cases. Whether you’re converting an existing building or developing a new one, understanding the planning requirements early on can save time, money and future headaches.

Here’s what you need to know.

Self Storage Use Class: What Is It?

In England and Wales, self storage usually falls under Use Class B8, which covers storage and distribution. This is important, because if your property isn’t already B8, you may need to apply for a change of use.

However, it’s not always that straightforward. Some local authorities treat self storage as a sui generis use (a unique category), which means it doesn’t fall neatly into any class and will almost always need full planning permission.

Converting an Existing Building

Conversions are a popular route for operators and investors. Former retail, warehouse or office spaces are often ideal for self storage, but their existing use class is rarely B8.

If you’re converting a site from retail (Class E), light industrial (B2) or offices, you’ll likely need to submit a change of use application, along with detailed plans showing how the building will be used.

At Kuboid, we’ve supported clients through this process many times, helping them repurpose everything from old high street stores to former manufacturing units into thriving storage facilities.

New Builds

For new builds, full planning permission is essential. Your application will need to include:

  • Site layout and architectural drawings
  • Access and transport considerations
  • Environmental and noise assessments
  • Flood risk reports (if applicable)

Each local authority will have its own requirements and timeline. That’s why it helps to work with an experienced team who understands the nuances of building for self storage.

Can You Start Without Permission?

In some cases, operators start with permitted development rights or test the concept with a temporary change of use. But be careful. Operating without full planning can put your investment at risk. You could be forced to close or make costly changes later down the line.
