Break Clause Calculator
Use this calculator to find out when you can activate the break clause in your tenancy agreement, the earliest date you need to serve notice to hit the break date, and when your tenancy would end. Break clauses apply only to fixed-term tenancies signed before 1 May 2026. If your tenancy started on or after that date, your tenancy is a periodic tenancy and you can give notice to leave at any time without relying on a break clause.
How to use this tool
- Enter your tenancy start date as shown on your tenancy agreement.
- Select how the break clause activation date is specified in your agreement: by a number of months, or by a specific date.
- Enter the notice period required by your break clause. This will be stated in your tenancy agreement, usually in weeks or months.
- If your agreement states that notice must expire on a rent payment date, enter the day of the month your rent is due.
- Indicate whether your break clause includes conditions, such as no rent arrears.
- Select Calculate break clause dates. Your results will appear below the form.
Understanding your results
Earliest notice date: This is the last date by which you must serve written notice to reach your break clause end date. If you miss this date, you cannot use the break clause to leave on the break date. Check your tenancy agreement for how notice must be given. Written notice is standard. Some agreements require delivery by recorded post or a specific form of words.
Conditions: Some break clauses apply only if specific conditions are met at the time of serving notice. The most common condition is no rent arrears. If your break clause includes conditions and any of them are not met when you serve notice, the notice may be invalid and your landlord can refuse to release you from the tenancy. Verify your position before serving notice.
If your break clause window has passed: If the break clause activation date has already passed without notice being served, the right to break may no longer exist. Read your tenancy agreement carefully. If the agreement allows multiple break points, the next one may still be available. If you are unsure, seek advice from Shelter or Citizens Advice before acting.

Break clauses and the Renters’ Rights Act 2025
A break clause is a contractual term, not a statutory right. It is only valid if it appears in your tenancy agreement in writing. The right to use a break clause can be conditional on meeting specific requirements set out in the agreement. Courts have interpreted break clause conditions strictly: if you are in rent arrears at the time of serving notice, a condition requiring no arrears is likely to be treated as unsatisfied.
Under the Renters’ Rights Act 2025, which came into force on 1 May 2026 in England, all new tenancies are periodic assured tenancies from the start. Fixed-term tenancies are no longer available for new tenancies. A break clause in a tenancy agreement dated on or after 1 May 2026 has no practical effect, because either party already holds the right to end a periodic tenancy by giving the required statutory notice. This calculator covers existing fixed-term tenancies only.
This tool covers England only. Scotland operates under separate legislation, including the Private Residential Tenancy, which does not use fixed-term tenancies or break clauses in the same way. Wales operates under the Renting Homes (Wales) Act 2016.
