What is the required notice period I must give for a rent increase?

The required notice period for a rent increase in the UK:

Periodic Tenancies (Month-to-Month, Weekly, etc.):

Minimum of one month's notice using Form 4 (Landlord's notice proposing a new rent).

You can technically give more notice, but one month is the legal minimum.

Fixed-Term Tenancies:

No rent increases during the fixed term unless:

• Tenant agrees and the agreement is amended in writing.
• Rent review clause exists and specifies notice period for increases.

Important notes:

The upcoming Renters (Reform) Bill proposes:

• Mostly periodic tenancies.
• A two-month notice period for rent increases (likely).
• Government-issued forms for notifying tenants and processing increases.

General tips:

• Always provide clear written notice, stating the new rent and effective date.
• Be open and transparent with your tenant about the reasons for the increase.
• Consult a letting agent or solicitor if you have any questions or concerns.
