kitchen vent

[confusedly]

I have just had a kitchen built in what was an old bedroom, with a big window to one side and and arch to a dining room the other, and of a window in the dining room. The kitchen installer (one of the big ones) said no mechanical vent was necessary, as the kitchen opened to the outside. The B.I. inspector says it should have had a mechanical vent with ducting to outside, minimum 60 litres per second. He won't accept using the old chimney unless ducting is fitted to the top (4 floors away!)

Who is right, and if it is the B.I. man, do I have any come back on the kitchen installer?

The BI is correct; as you’ve converted an old bedroom, it's a new installation & so must have a mechanical vent; a kitchen without one won't be much fun to use anyway. I would also go for the largest extractor you can get, although the minim will meet LABC requirements, it’s rather marginal.

a cooker hood at 30 litres / sec or extract fan at 60 litres .

Must be ducted to fresh air , hopefully you already have a suitable trickle vent in place

thank you. Actually I did put a cooker hood in but it goes up the old chimney and the B.I. man did not like that - he said it must be ducted to fresh air. I suppose there are chimney liners, but it would expensive and dfifficult to put one in now.
