Rent Increases in Wales: What Landlords Need to Know in 2026

Rent increases remain an important consideration for landlords and tenants across Wales. However, unlike England, Wales operates under its own housing legislation through the Renting Homes (Wales) Act.

Key points for Welsh landlords include:

• Rent can only be increased if the contract allows for it or by following the correct legal procedure.

• Landlords must give tenants the required written notice before any increase takes effect.

• Rent cannot usually be increased during the first 12 months of an occupation contract.

• Tenants who believe a rent increase is excessive may be able to challenge it through the appropriate process.

For buyers considering tenanted auction properties, it is important to review the occupation contract carefully and understand when rent was last increased. Sellers should ensure all tenancy documentation is up to date and compliant with Welsh regulations.

Takeaway: Before buying or selling a tenanted property in Wales, check the occupation contract, rent history, and notice requirements to avoid unexpected issues after completion.
