A rent guarantee for commercial property sounds reassuring. And it can be. But only if it holds up when you need it, not just when it sits neatly in the lease folder.
In a market with higher costs and more tenants facing pressure on liquidity, security is not a legal appendix for specialists. It is ordinary, practical risk management.
What is a rent guarantee?
In short, a third party — often a bank, insurer or parent company — provides security for the tenant's obligations. It is often used instead of a deposit because the tenant does not have to tie up capital in an account.
For a landlord, it can be a good solution — but only if the guarantee covers the right claims, amount and period. This is where many people move a little too quickly.

Seven things to check
1. What the guarantee actually covers
Do not assume the guarantee covers everything in the lease. Check whether it also covers service charges, VAT, interest, damage, expenses and other contractual claims.
2. Whether the guarantee amount is still sufficient
An amount that made sense at signing may become too low after CPI indexation, floor-area changes or new lease terms. The guarantee should therefore be reviewed regularly, not simply filed away.
3. How long the guarantee lasts
Security should normally last beyond the lease period itself. Claims often arise at move-out, final settlement or a later review. If the guarantee expires too soon, it may be little more than decoration.
4. Who actually provides the guarantee
Bank guarantees, insurance guarantees and parent company guarantees have different risk profiles. What matters most is knowing who must pay if something goes wrong, and which conditions must be met.
5. Notice deadlines and formal requirements
Many guarantees specify how claims must be submitted. The wrong recipient, late notice or incomplete documentation can make a good guarantee harder to use.
6. What happens when the tenancy changes
Options, renegotiations, floor-area changes and new rent terms should trigger a review of security. The lease evolves, and the guarantee needs to keep up.
7. Where the documentation is stored
A good guarantee is of little use if nobody can find the right version when it is needed. Record the amount, expiry date, guarantor, notice rules and latest review in one place.
