GISC rules are as per the following extracts -

SECTION E - Code Practice Requirement

Practice Requirement E1 - E-Commerce

21. Both email and a website are acceptable forms of writing for the purposes of the requirements of the Private Customer Code when dealing with Private Customers.

22. However, where a Private Customer needs to be actively informed of an event such as a renewal or change of policy wording, website-based notification is not acceptable and the Private Customer should be contacted by other methods, such as email.

On this basis it can be seen that email only is acceptable for document transmission and hard copy by post is not required.
