August 18, 2025
Investing in self-storage in the UK is an exciting opportunity, but success depends on thorough due diligence. At Harrington Wyles Self Storage Consultants, we help investors uncover risks, optimise operations, and make informed decisions.
Here’s a practical, step-by-step guide to legal and operational due diligence when buying a self-storage property.
Why Due Diligence Matters
Before signing a contract, due diligence helps you:
- Verify the property’s legal status.
- Assess the financial health of the business.

Without proper checks, even seemingly profitable properties can turn into costly mistakes.

- Check for asbestos in older buildings.
- Assess flood risk and compliance with environmental laws.
4. Lease & Tenancy Agreements
