A gas safety check involves our Gas Safe registered engineer inspecting your gas appliances.  
  
We will check the appliance is working correctly and will check the following four areas:
•	Gas appliances are on the right setting and burning correctly with the correct operating pressure
•	Harmful gases are being removed from the appliance safely to the air outside
•	That any ventilation routes are clear and working properly
•	All the safety devices are working
The check will identify any defects which require remedial work.
