Gas & Carbon Monoxide Safety in Scottish HMOs

Shared Housing, HMOs & Lodgers Scotland 3 min read · published March 29, 2026 Flag of Scotland

Living in a House in Multiple Occupation (HMO) brings extra responsibilities for both tenants and landlords. This guide explains what renters in Scotland should know about gas safety and carbon monoxide risks, how to spot hazards, and what legal steps you can take if problems are not fixed. It covers landlord duties, tenant actions, the forms and evidence you will need, and where to get official help from local authorities or the tribunal. The language is practical and aimed at tenants and renters dealing with repairs, inspections or safety concerns, so you can act quickly to protect yourself and housemates. Read the steps below to know what to do next.

Landlord duties and tenant rights

Landlords in Scotland must ensure gas appliances are maintained, that alarms are fitted where required, and that tenants are given relevant safety information. Tenants have the right to a safe property and can seek enforcement through local authorities or the First‑tier Tribunal (Housing and Property Chamber) if problems are not fixed.[1][2][3][4]

Keep a copy of any safety certificate you receive from your landlord.

Key landlord responsibilities

  • Arrange annual gas safety checks and provide the gas safety record (CP12) to tenants.
  • Install and test smoke and carbon monoxide alarms according to Scottish regulations.
  • Allow reasonable access for safety inspections after proper notice.
If you smell gas, leave immediately and call the emergency number from a safe place.

What tenants should do

  • Keep records of communications, certificates and photos of unsafe conditions.
  • Report hazards to your landlord promptly in writing and request repairs.
  • Submit an application to the First‑tier Tribunal if essential safety work is not completed and you need enforcement.
Timely, written reports help create clear evidence if you need formal enforcement.

Official forms and how to use them

Below are the most relevant official documents you may need when dealing with gas or carbon monoxide safety issues in an HMO.

  • Gas safety record (CP12): issued after an annual gas safety check by a Gas Safe registered engineer; ask your landlord to provide a copy and retain it as proof. Example: "I requested my CP12 after the check and kept a scanned copy for my records."[4]
  • Application to the First‑tier Tribunal (Housing and Property Chamber): use the tribunal's application guidance to choose the correct application route and attach evidence such as CP12s, photos and dated messages when seeking enforcement.[3]
  • Private Housing (Tenancies) (Scotland) Act 2016: the primary statute setting out tenant rights and landlord obligations in Scotland; refer to relevant sections when explaining your legal position to a landlord or tribunal.[1]
You can combine photographs, dated messages and certificates to build strong evidence for a tribunal application.
