Common questions

Is this the law?

Yes. The rules on rent increases are law in Northern Ireland. They come with no certificate and no renewal date, so there is nothing for Beamwise to remind you about: it lists them beside each property for reference. Private Tenancies (NI) Order 2006, Arts 5D and 5E, from 1 April 2025: rent may not rise within 12 months of the tenancy starting or of the last increase, and needs at least 3 months' written notice. An increase that breaks these rules has no effect. Cash rent payments need a written receipt (Art 5).

Is there anything to renew?

No. The rules on rent increases in Northern Ireland are rules to follow, not a certificate, so there is no renewal date.

Who has to follow these rules?

The landlord (or their agent).

Do they apply to every rented property in Northern Ireland?
