All our Members and contacts can be assured that through our virtual presence, our focus on delivering tangible benefits remains. The teams continue to work hard in developing a varied events programme to appeal to a wide audience, delivering a CPD training programme, developing good practice guidance as well as providing the usual level of support that you - our Members and the wider industry have come to expect.  We will also continue to hold face to face meetings and events as business needs arise and look forward to working with you.
