RISA authentication

Having received an unsolicited email apparently from RISA, who conduct inspections for FENSA, requesting access to my property at short (a couple of days) notice, I wanted to confirm it was genuine. I found no link to RISA's website from FENSA's. When I emailed enquiries the automated reply said I would receive a response within three working days which would have been too late. I only got voicemail when I rang but despite leaving no message someone called me back confirming verbally and by email the RISA contact was genuine.
