Hi,

Have an existing porch about 1500mm square, half height brick ,tiled roof with 2 x 1200mm windows and one standard door all in wood, now 40 years old.

Am replacing the door and both windows with UPCV and know about the 2022 regulations for using Trickle Vents for new and replacements.

However for such a small area, do we have to fit these vents onto all three, or will just on one window be acceptable ?

A porch is exempt, but at least one vent would be prudent
