If you have sent a membership request, sales goods order or a donation by mail to us recently please be patient with our response as we rely on a forwarding system to distribute paperwork to the relevant volunteers that deal with these areas and there is therefore a delay involved.

This site is not administered from our office address above, so if you want leaflets or posters etc, please arrange via the telephone or we can forward emails for you. 

The HSA is 100% volunteer run and our volunteers have ‘normal’ jobs, so please bear with us if you experience a delay
