The rules for letting a home safely are devolved. If you let property in Scotland, Wales or Northern Ireland, the law that applies depends on where the property is, not where your business is based. This guide covers the duties that differ most: alarms, electrical safety, tenancy deposits and licensing of shared houses.
For England, see the Landlord safety and legal duties for rented homes guide, which covers the England rules and the rules that apply across Great Britain, such as the annual gas safety check.
Which rules apply to you
- The property is in Scotland: every home must meet the tolerable standard, which includes interlinked smoke and heat alarms and carbon monoxide alarms. Deposits must go into one of three approved schemes within 30 working days.
- The property is in Wales: you must have a valid electrical condition report at least every five years and give a copy to the contract-holder within 14 days, and fit mains-connected, interlinked smoke alarms and carbon monoxide alarms.
- The property is in Northern Ireland: you must fit interlinked smoke and heat alarms and carbon monoxide alarms under the Private Tenancies Order 2006, have every electrical installation inspected and tested at least every five years, and get a council HMO licence for any house in multiple occupation.
- You let in more than one nation: meet each nation's rules for each property. Nothing you do to comply in one nation counts in another.

How the duties on alarms, electrics, deposits and shared houses differ in Scotland, Wales and Northern Ireland.
| Point of comparison | Scotland | Wales | Northern Ireland |
|---|---|---|---|
| Where the alarm duty comes from | Tolerable standard in the Housing (Scotland) Act 1987, as extended by SSI 2019/8; for rented homes, the repairing standard in the Housing (Scotland) Act 2006 | Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022, regulation 5 | Article 11B of the Private Tenancies (Northern Ireland) Order 2006 and the 2024 Regulations |
| Smoke alarms | Living room or most used room, and every hallway and landing; interlinked and ceiling-mounted | One on each storey, connected to the mains and linked to the other mains-connected smoke alarms | Most used living room and every circulation space on each storey; interlinked; hard wired or sealed battery |
| Heat alarm | One in every kitchen | Not required by the Regulations | One in every kitchen |
| Carbon monoxide alarm | Where a carbon-fuelled appliance such as a boiler, open fire or wood burner is in the room | In each room with a gas, oil-fired or solid fuel combustion appliance | In any room or circulation space with a fixed combustion appliance or flue |
| Electrical safety | Electrical installations must be in a reasonable state of repair and proper working order, including residual current devices, as part of the repairing standard (section 13(1)(c) of the 2006 Act) | Valid electrical condition report at least every 5 years, copy to the contract-holder within 14 days | Every electrical installation inspected and tested by a qualified person at least every 5 years (sooner if the report says so). First check before a new tenancy starts, or by 1 December 2025 for existing tenancies. Copy of the report to existing tenants within 28 days and to new tenants before they move in (Electrical Safety Standards for Private Tenancies Regulations (Northern Ireland) 2024) |
| Tenancy deposits | Approved scheme within 30 working days; First-tier Tribunal can order up to three times the deposit | Not covered by this guide. See the Protect tenant deposits within 30 days guide | Not covered by this guide |
| Shared houses (HMOs) | Council HMO licence under the Housing (Scotland) Act 2006. Not covered by this guide | Council HMO licensing under the Housing Act 2004. Not covered by this guide; see the Landlord safety and legal duties for rented homes guide | Council HMO licence under the HMO Act (Northern Ireland) 2016: 5-year licence, fine up to £20,000 for an unlicensed HMO |
| Main enforcer | First-tier Tribunal (Housing and Property Chamber) for the repairing standard; local authorities | The courts, on the contract-holder's claim for breach of the fitness duty | District councils, which prosecute and can offer fixed penalties |
| Consequence of breach | Repairing standard enforcement order; ignoring it is an offence, fine up to level 3 | Dwelling treated as unfit for human habitation; court can order the landlord to perform the duty | Offence, fine up to level 4 for alarms (Article 68(1) of the 2006 Order). For electrical safety, the council serves a remedial notice and can arrange the work itself if you do not comply |
Steps to get compliant
- List every property by nation and note who the landlord is, the tenancy or contract type and the date each tenancy started.
- Survey the alarms in every home. Count storeys, circulation spaces, kitchens and fixed combustion appliances, then fit what each nation's rule requires.
- In Wales, book the electrical inspection from a qualified person and diarise the five-year re-inspection and the 14-day deadline for giving the report to the contract-holder.
- In Scotland, choose a deposit scheme before the first tenancy starts and pay in within 30 working days, together with the information the tenant must receive.
- In Northern Ireland, have each electrical installation inspected and tested and give tenants the report, then check whether any property is an HMO and apply to the district council, with planning permission in place, before anyone moves in.
- Keep records of installation dates, inspection reports and deposit confirmations. Each nation's enforcer will ask for them first.
