If your flue liner is not long enough for your installation there will undoubtedly be delays and disappointment (plus the additional cost of a correctly sized flue liner). Adding an extra metre (or two) - will help ensure your installation goes ahead without delay.

The flue liner legally needs to be a minimum of 6" in diameter if you are burning wood. Unless when you install a DEFRA approved stove with a 5" flue outlet, in which case you can use a 5" liner.
