Hi Again,
Thanks for all the replies and help. A month on and I am still a tad confused. I understand the legislation allows me a little leeway, due to the fact that it does not state that vents are compulsory. Personally I would be happy to move into the house as it is, I believe in opening windows left, right and centre! However I have had mixed responses to this, mainly about carbon monoxide poisoning etc. If I have a radon barrier does this not prevent dangerous levels of carbon monoxide entering the house??
Once again all help greatly appreciated!
Deirdre
