Where to vent an Extractor hood

[DemiDon]

Can any one help?

I'm about to buy a cooker extractor hood but I have an internal kitchen.

The kitchen configuration is such that I must vent to the right and along the wall where it will eventually meet some fresh air (once I've put a hole through two cavity walls - don't ask!).

BUT... Hoods only seem to come with vent holes at the back or straight up.

So... Is there a regulation that says only back or up?
Will I have to cut my own hole in the side? Has any one done this?

Thanks

You should be able to use this type of accesories to come out the top or back & then vent through the wall http://www.screwfix.com/cats/100139/Heating-Cooling/Ducting

Thanks for that, it looks as if I can't go to the side
1. I'd have create my own exit hole in the side of the chimney section
2. I'm told that venting out along a length of 3m or greater is not recommended and I have 5m to travel

Therefore
I must go directly out the back of the chimney section and then up through a flat roof. I don't suppose you know of a flat roof fitting for an extractor kit?
