Confined spaces in Landlords demise

I thought as much, many thanks for the response it really is much appreciated.

There is no duty in law for anyone to maintain a confined space Register, many water companies do it as good practice after conducting a risk assessment on them , they then Categorise them accordingly and enter the category on a register, this helps contractors/maintenance workers establish safe systems of work for each category, as far as domestic premises go apart from cellars or plant rooms i can't think of where confined spaces would figuer or of a significant risk involved

Is there a duty placed on Landlords to maintain a confined spaces register?
