Answer
If a commercial landlord increases your rent, as the tenant, you have the right to question the increase and dispute it if you feel that it isn’t fair for instance.
On the other hand, if your commercial lease has a rent review clause, the landlord can increase the rent if they feel it is necessary as a result of inflation or rent hikes in the area. Usually, rent reviews come up every 3-5 years, allowing the landlord the option to change your rent.
Before you sign a commercial lease, it is a good idea to check it over with a specialist commercial lease solicitor first to make sure that you understand all the terms and are not caught out by things like rent review clauses.
