How rent increases changed in 2026

The Renters' Rights Act 2025 (in force 1 May 2026 in England) ended rent review clauses for increasing rent, extended the section 13 notice period to 2 months and kept increases to once per year. Northern Ireland's Private Tenancies Act (NI) 2022 brought in 3 months' notice from 1 April 2025. Wales (Renting Homes (Wales) Act 2016) and Scotland (Private Housing (Tenancies) (Scotland) Act 2016) already required 2 and 3 months respectively.
