English Heritage produces guidance and policy on all aspects of managing the historic environment. It is most easily accessible through www.helm.org.uk
A full sub-section of the website is dedicated to climate change and this can be reached through the Managing and Protecting link at the top of the home page.
Alternatively, from the home page, click on the Guidance Library link on the left hand side, then choose English Heritage guidance. This will take you to a full alphabetical list of all current guidance and policy.
