Why Smoke Alarm matters for landlords

The 2022 amendment brought social-housing level smoke-alarm duties into the PRS. The test-at-tenancy-start obligation is active even for back-to-back relets, and the duty to replace faulty alarms once reported is an on-going one. Keep a dated inventory photo of every alarm at check-in and a repair log for any reported failures.

CO Alarm (Carbon Monoxide Alarm)

Required from 1 October 2022 in every room with a fixed combustion appliance (excluding gas cookers) in private rented homes in England. The landlord must ensure an alarm is present and in working order at the start of each tenancy. Maximum civil penalty: £5,000 per property.

SA105 (Property Pages)

The UK Property supplementary pages of the Self Assessment tax return, where landlords report rental income and expenses. It sits alongside the main SA100 return. Under Making Tax Digital for Income Tax, landlords over the income threshold move from the annual SA105 to digital quarterly updates plus a final declaration.

Schedule 2 (Housing Act 1988 Possession Grounds)

The schedule of statutory grounds a landlord uses to seek possession of an assured / assured shorthold tenancy under Section 8. Grounds 1–8 are mandatory (court must grant possession if proven): includes ground 1 (landlord-occupier intent), ground 1A (landlord sale, post-RRA 2025), ground 8 (3+ months rent arrears post-RRA 2025), ground 14 (anti-social behaviour). Grounds 9–17 are discretionary (court considers reasonableness): includes ground 11 (persistent late payment) and ground 12 (breach of tenancy). Choice of ground sets the notice period and the burden of proof.

Schedule of Condition

The room-by-room photographed report of the property’s condition at check-in (and updated at check-out). Distinct from the Inventory (which lists items and their condition); Schedule of Condition focuses on the fabric of the property: walls, floors, fittings, decoration. Together they form the deposit deduction evidence base. Required to win a fair-wear-and-tear contested deduction at the DPS, TDS or mydeposits adjudication; absence usually means the deposit is returned in full to the tenant.

Section 13 Notice

The only lawful way to raise rent on an assured periodic tenancy. An increase cannot take effect until 52 weeks after the tenancy began or after the last increase, with a 53-week correction where the 52-week date would fall more than six days before the anniversary of the first increase after 11 February 2003, and with at least two months' notice (extended from one month by the Renters’ Rights Act 2025). Tenant can refer to the First-tier Tribunal, which determines the market rent; that figure may be higher or lower than the landlord proposed, but the tenant will not be required to pay more than the amount in the notice.

Section 21 Notice

The no-fault eviction notice under Section 21 of the Housing Act 1988. Abolished for new notices from 1 May 2026 under the Renters Rights Act 2025. Landlords must now use Section 8 with a specified ground.
