What this topic is
- Landlords in England must arrange a gas safety check on all gas appliances, flues and pipework in a rented property at least every 12 months.
- The check must be carried out by a Gas Safe registered engineer.
- The resulting record is commonly called a CP12 or Landlord Gas Safety Record. A copy must be provided to existing tenants within 28 days and to new tenants before they move in.
Why it matters to landlords, letting agents and homeowners
- An out of date or missing CP12 is a serious compliance breach and can lead to enforcement, fines or invalidated insurance.
- Faulty gas appliances are a leading cause of carbon monoxide poisoning, which is a recognised HHSRS hazard category.
- Letting agents typically need clear visibility of CP12 status across every managed property.
How it connects to property safety and compliance
- Annual checks help identify worn or faulty appliances before they fail dangerously.
- Combustion problems can produce carbon monoxide, which is colourless and odourless.
- Combined with working CO alarms, regular Gas Safe checks form the core gas safety position.
How Sunderland Landlord Compliance can help
- Coordinate annual CP12 bookings with Gas Safe registered engineers.
- Offer an optional boiler service add-on at the same visit to reduce coordination effort.
- Store the returned record against the property and track the renewal date.
