Commercial rent review
Commercial rent reviews before signing a lease
A commercial lease can look affordable at the starting rent but become tighter later if rent review wording, review dates, indexation or future increases are not understood before signing.
Use this page to check how the rent may move later, then run the free commercial check if you want to pressure-test the lease together.

Why rent reviews matter
Starting rent is not the full story
A site can look affordable today and still become tighter if the review clause allows the rent to rise later.
Future rent affects the margin of safety
Higher rent reduces room for staff, rates, utilities, insurance, and slower trading months.
Timing matters
The break clause, review date, and rent-free timing should be considered together before signing.
Lease wording matters
Indexation, market review, or upward-only wording can all change how the lease behaves after opening.
Rent review versus starting rent
The question is not just whether the site can afford rent today.
It is what happens if the rent changes while the business is still proving itself.
Starting headline rent
The rent shown at the start of the lease.
Rent-free period
Delays some rent, but does not remove future rent review risk.
Stepped rent
Raises rent in stages rather than all at once.
Rent review clause
Sets out how and when the rent can change later.
Index-linked review
Adjusts rent by reference to an index if the lease uses that method.
Market review or upward-only wording
Can lead to a higher rent later depending on lease terms and market conditions.
Break clause timing
The lease may be more flexible if the break arrives before a review date.
Illustrative example
A fictional site becomes harder to judge once future rent is part of the picture.
This is an illustrative scenario, not a real case study.
Annual rent
£60,000
Monthly rent
£5,000
Expected monthly revenue
£24,960
Rent burden
20.0%
Break-even customers/day
45.2
Opening cash buffer
£9,000
At a 20.0% starting rent burden, even a future rent increase can matter because the lease already has limited room for error.

Paid file
The £49 Standard commercial viability file turns the check into a printable memo.
It organises the assumption review, stress-test interpretation, negotiation levers, evidence checklist, and lease questions in one place.
If rent review wording changes the picture enough to keep the site in play, the sample file shows the format and the Standard file turns the result into a decision-support memo after the free check.
Frequently asked questions
Commercial rent review FAQs
Short answers for people comparing future rent risk, affordability, and lease viability.
What is a commercial rent review?
A commercial rent review is a clause that allows the rent to be checked and potentially changed at a future point in the lease. The exact effect depends on the wording of the lease.
Why does rent review wording matter before signing?
The starting rent is not the only rent risk. If the review wording allows a higher future rent, the site can become tighter later even if it looks manageable on day one.
Is starting rent enough to judge affordability?
No. A starting rent can look fine while the review timing, indexation, or market review clause creates a stronger cost later on.
Should I check rent review timing against a break clause?
Yes. The timing matters because a lease can feel very different if the break clause comes before or after the first review date.
Can a rent review affect commercial lease viability?
Yes. If the current rent burden is already tight, a future increase can narrow the margin for staff, rates, utilities, and slower trading months.
