The warranty extension will become active when the manufacturers or suppliers warranty finishes at the end of the first, second or third year.

Warranty extensions are available for a further one, two, three or four years to provide total cover for a maximum of five years.

So for example an item coming with a one year manufacturers warranty a +2 year warranty extension will mean that you have cover for a total of three years.

Or as another example for an item coming with a three year manufacturer warranty a +1 year warranty extension will mean that you have cover for a total of four years.
