Cheques need to be payable to the HSA please and sent to: BM HSA, London, WC1N 3XX, U.K.

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. If you would like leaflets or posters etc, please email the Information Officer.

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