The SRP Membership List, which used to be printed and sent to members every two years, is now online. This means that the list is always up to date whenever you look at it. You can look at a particular branch as well as lists of honorary members, officers, visiting conductors and affiliated organisations, or you can search for a particular member by name.
You can find the list from the About Us menu or go directly to https://srp.org.uk/membership-list. The list is only available to current members, so you will need to login to see it.
