Modern stoves can be converted to DEFRA certified by the kit supplied by the manufacturer and installed within a matter of minutes. This is because a Defra approved stove must undergo very rigorous tests and must be restricted on how much smoke it can generate.

To ensure that these restrictions are maintained during testing the stove must be able to limit its combustion air supply to ensure that it does not exhaust itself of oxygen, which may cause it to smolder. This is achieved by the mechanism that allows a small amount air into the firebox when it's burning. It is typically hidden within the stove or beneath the base of the fire box.

DEFRA stoves disadvantages approved stoves, also known as SE (Smoke Exempt) Stoves, have undergone rigorous testing to demonstrate that they can cleanly burn authorised fuels within a Smoke Control Zone.
