A Section 13 checker (also known as a Section 13 tool or Section 13 calculator) is a free online tool that helps UK landlords determine if they can legally serve a Section 13 rent increase notice. Our free Section 13 checker calculates notice periods, verifies eligibility, and ensures you comply with all legal requirements.
A Section 13 notice is the formal legal process for increasing rent on assured periodic tenancies and statutory periodic tenancies in England. It uses Form 4, the government's prescribed form, and must follow strict rules about timing and procedure. Use this free Section 13 tool to check if you can serve one.
You can use Section 13 when:

Our Section 13 calculator asks about your tenancy type, rent payment frequency, and key dates. It then calculates the minimum notice period and the earliest effective date for your rent increase, ensuring compliance with UK housing law.
There's no legal cap on rent increases, but the new rent must be a 'market rent' - what a similar property would achieve in the local area. If tenants challenge at tribunal, the tribunal will assess whether the rent is fair compared to similar properties.
Tenants cannot simply refuse a valid Section 13 notice, but they can refer it to a tribunal before the effective date. If they don't refer it and don't pay, you can pursue the rent through normal debt recovery processes.
If the Section 13 notice contains errors (wrong dates, incorrect form, etc.), it may be invalid. The tenant could challenge it and you may need to serve a new notice. Always double-check the form before serving - that's why using a Section 13 checker tool is so important.
Using a Section 13 tool or checker before serving your notice helps ensure you meet all legal requirements. An invalid notice can be challenged by tenants, delaying your rent increase and potentially costing you money in lost income and legal fees.
