Minor Mistake With no Trickle Vents in Bifold Doors If you want to know how your DIY projects could be affected by building and planning regulations, click here to post questions and view answers

Hi all,
I’m looking for some advice.
I’m currently building my own extension under building control etc and have just taken delivery of the bifolds.
I noticed they didn’t have trickle vents.....I looked through the order and realised I didn’t specify them!
Now I hate them anyway but that’s another topic.
I have looked through the internet and tried to get an idea regarding whether it is acceptable or not but haven’t had any luck.
Obviously it is a costly mistake, but how can I get around this?
I will fess up to my bco but am looking at the options first

If you have another window or door serving the room(extension) which has a trickle vent then the bi folds will not require any. This may depend on the size of the extension i.e. if it is a very large extension you may require more than one trickle vent
