Whilst work at height is most certainly not a topic I have extensive knowledge of, I thought I’d share the following link as it may help others when considering such matters; or when simply looking to gain a better understanding of work at height matters. I do of course fully advocate seeking specialist assistance when required, but having some knowledge of good practice can assist in making that decision and also in ensuring that any assistance sought or work performed is in order. I should also point out that I have no connection (commercial or otherwise with this company) http://www.accessindustryforum.org.uk/advice.htm
