Frequently asked questions
What electrical safety checks do landlords need?
Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 (SI 2020/312, in force for new tenancies from 1 July 2020 and existing tenancies from 1 April 2021, legislation.gov.uk), landlords in England must have a valid EICR (every 5 years), working smoke alarms on every floor, and a CO alarm in rooms with solid fuel appliances. From October 2022, CO alarms are also required in rooms with gas appliances. Non-compliance can result in fines up to £40,000, raised from £30,000 on 1 November 2025 by the 2025 Amendment Regulations (SI 2025/1043, regulation 10, legislation.gov.uk).
How much should I budget for electrical compliance per property?
Budget approximately £100-£250 per property for an EICR (Checkatrade Electrical Safety Check cost guide, 2026), and an average £100 per smoke or CO alarm installed, from £40-£75 for battery-powered to £75-£125 for mains-wired (MyJobQuote, Install a Fire Alarm cost guide, updated 24 March 2026). For a typical 2-bed rental needing an EICR plus a handful of alarms (2 smoke alarms and a CO alarm), total compliance costs are usually £400-£550. Factor this into your annual maintenance budget.
Can I do the electrical safety checks myself?
No. EICRs must be carried out by a qualified and competent electrician, ideally registered with an approved scheme like NICEIC or NAPIT. Landlords can install battery smoke alarms themselves, but mains-wired alarms must be fitted by a qualified electrician.
What happens if I do not have a valid EICR?
Local authorities can issue a remedial notice requiring you to obtain an EICR within 28 days. Failure to comply can result in fines of up to £40,000 per property, raised from £30,000 on 1 November 2025 (Electrical Safety Standards in the Private Rented Sector (England) (Amendment) (Extension to the Social Rented Sector) Regulations 2025, SI 2025/1043, regulation 10, legislation.gov.uk). You must also provide a copy of the EICR to tenants within 28 days of the inspection.
What about gas and EPC obligations?
Beyond electrical safety, landlords in England must arrange an annual Gas Safety Check by a Gas Safe registered engineer for any gas appliances (giving tenants a copy within 28 days), and provide a valid Energy Performance Certificate (EPC) rated at least E to legally let the property under the Minimum Energy Efficiency Standard (GOV.UK, domestic private rented property MEES landlord guidance, updated May 2026). That E minimum is due to rise to C for all tenancies from 1 October 2030. Rules differ in Scotland and Wales, so check your local requirements.
Do deposit protection and right-to-rent affect compliance?
Yes. These are separate legal duties alongside safety. Any deposit taken on an assured shorthold tenancy in England or Wales must be protected in a government-approved scheme (such as DPS, MyDeposits or TDS) within 30 days, with prescribed information given to the tenant (GOV.UK, tenancy deposit protection guidance). You must also carry out right-to-rent immigration checks on all adult occupiers before the tenancy begins. Right-to-rent does not currently apply in Scotland, Wales or Northern Ireland.
