If it's urgent, skip us.
Leave the property. Call your country's national gas emergency line from outside — save the number before you need it.
Open windows, turn appliances off, leave the property, and call your local medical / emergency line if anyone feels unwell.
In very cold weather, contact your local welfare or utility priority line. Many countries run a “priority services” scheme for vulnerable households.
Call your local emergency number first. Use AST only to help describe the aftermath to an engineer.
