How do I increase the rent under the Renters' Rights Act as a landlord?

How do I increase the rent under the Renters' Rights Act as a landlord? Since 1 May 2026 you must use Form 4A, the section 13 notice, served at least 2 months ahead. Rent can rise once a year, not in the first year, and your tenant can challenge it at a tribunal. Yes. GOV.UK says you must follow the section 13 process every time you increase the rent, even if your tenant has already agreed. No. Rent review clauses no longer take effect in private tenancies in England. An increase agreed under one before 1 May 2026 but due to start after that date will not apply. The yardstick is the open market rent: what you could reasonably expect if you let the property on the open market on the same terms. If the tenant challenges, the tribunal decides, and the tenant never pays more than you proposed. Read the full answer, with every source, at rightotax.co.uk.
