Open full guideWhy Gas Safe Register matters for landlords
The 2009 transition from CORGI to Gas Safe is old news for experienced landlords but still causes false compliance for landlords relying on legacy tradesmen. A handyman uncle doing "the same thing CORGI did" is an unregistered gas operative and the CP12 they produce is legally worthless. Two minutes on gassaferegister.co.uk protects a prosecution defence.

Related terms
CP12 (Gas Safety Record)
The document issued after an annual gas safety check by a Gas Safe registered engineer, commonly called a Gas Safety Certificate. Landlords must renew it every 12 months, give the tenant a copy within 28 days of the check, and give new tenants a copy before they move in. Non-compliance is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998.
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.
Compliance Score
A 0-100 score LetCompliance assigns to each property based on how up-to-date its safety certificates and tenancy documents are. 100 means Gas Safety, EICR, EPC, deposit protection and Right to Rent are all current; the score drops as deadlines approach and is recalculated daily.
Form 6A (Section 21 Notice)
The prescribed form a landlord must use to serve a Section 21 “no-fault” possession notice in England, until Section 21 is abolished on 1 May 2026 by the Renters Rights Act 2025. Two months’ minimum notice; void if any of the prerequisites (deposit protected within 30 days, valid Gas Safety record, current EPC, How to Rent guide given) is missing. After 1 May 2026 Form 6A is no longer issuable for new notices and possession is pursued under Section 8 / Form 3 only.
Landlord and Tenant Act 1985 (Section 11)
The cornerstone repair-obligation statute for residential lets in England and Wales. Section 11 implies into every short-term residential tenancy a landlord obligation to keep in repair the structure and exterior of the property, and to keep in repair and proper working order the installations for water, gas, electricity, sanitation, space heating and water heating. Cannot be contracted out of. Breach is the basis for tenant disrepair claims and Awaab’s Law SLA enforcement under the Renters Rights Act 2025.
Landlord Database (Private Rented Sector Database)
A national digital register of private landlords and rented properties in England, established under the Renters Rights Act 2025. Every landlord must register and provide property details and proof of compliance (gas, electrical, deposit protection, EPC) before letting. Operated by central government, accessible to local councils and tenants. Failure to register is an offence with civil penalty up to £7,000 per breach, and a court can refuse a possession order under Section 8 if the property or landlord is not registered.
