Rent Increase Notice (Section 13)
Quick answer
A notice under Section 13 of the Housing Act 1988 used to increase rent on an assured periodic tenancy. Under the Renters Rights Act 2025 (in force 1 May 2026) the landlord must give at least 2 months’ notice on the prescribed Form 4A (Form 4 was the pre-reform version), can use it only once in any 12-month period, and cannot raise rent in the first 12 months of a tenancy. Tenants can challenge the increase at the First-tier Tribunal, which can no longer set a higher rent than the landlord proposed.

Open full guideWhy Rent Increase Notice (Section 13) matters for landlords
Under RRA 2025, Section 13 is the only lawful rent-review mechanism on an assured periodic tenancy in England. Tenants can refer a raised rent to the First-tier Tribunal which has the power to cap the increase at the open-market rate — so landlords should evidence their proposed rent against Rightmove/ONS data. The 12-month rule is a hard minimum; a second notice inside 12 months is void.

Rent Bidding Ban
A Renters’ Rights Act 2025 rule that stops landlords and letting agents in England inviting or encouraging offers above the advertised rent. From 1 May 2026 a property must be advertised at a fixed asking rent, and the landlord cannot accept — or invite a tenant to make — a bid higher than that figure. It targets the "sealed-bid" rent auctions that pushed prices up in high-demand areas.
Rent Repayment Order (RRO)
A First-tier Tribunal order requiring a landlord to repay up to 12 months’ rent (24 months under the Renters Rights Act 2025 for some offences) for specified housing offences: unlicensed HMO, breach of selective licensing, illegal eviction, harassment, failure to comply with an Improvement Notice or Banning Order. Sought by the tenant or, separately, by the local council. Triggered without needing a criminal conviction — the tribunal applies the criminal standard of proof to the underlying offence, then orders repayment.
Rent-to-Rent (R2R)
An arrangement where a middle party rents a property from the owner on one agreement, then sub-lets it (often room by room as an HMO) to occupiers for a higher total rent, keeping the margin. Legitimate only with the owner’s written consent, the correct tenancy type and — critically — the right HMO licence held by whoever is the "person in control". Done without consent or a licence it is a common source of unlawful-eviction, deposit and licensing liability.
Rental Yield (Gross / Net)
The annual return on a rental property as a percentage of its value. Gross yield is annual rent ÷ property price × 100; net yield subtracts running costs (management, insurance, maintenance, a void allowance, ground rent/service charge) before dividing. Neither is the real return until you also take off mortgage interest and tax — after Section 24 and Making Tax Digital, the after-tax yield is what actually matters.
Renters Rights Act 2025
UK legislation that received Royal Assent in 2025 and came fully into force on 1 May 2026. Abolished Section 21 no-fault evictions, converted all ASTs to assured periodic tenancies and gave tenants the right to request a pet. It also contains powers, not yet exercised, for a private rented sector database (phased rollout from late 2026), a Landlord Ombudsman (expected 2028) and a Decent Homes Standard for the PRS (proposed 2035 or 2037).
Renting Homes (Wales) Act 2016
The Renting Homes (Wales) Act 2016 is the main law for renting a home in Wales. It has been in force since 1 December 2022. It replaced assured shorthold tenancies with "occupation contracts", and tenants are now called contract-holders. Private lets use a standard contract, and social housing uses a secure contract. The Renters Rights Act 2025 covers England only, so Welsh lets follow different rules.
