Additional important notes
The HSE ceased regulating in 2013, as such any qualification with them is valid up until the expiry date only. Trainers must then complete a Level 3 Award in First Aid at Work (QCF).
All qualifications now need to be regulated as stated by the Skills for Health Council and Ofqual as of October 1st 2015.
AoFA Qualifications will accept FAW certificates from both St John's Ambulance and the British Red Cross and St Andrews as long as they are valid and in date. This is due to these organisations having a known quality assurance system. Please however understand that these qualifications are unregulated and you will may will need to get a Level 3 Award in First Aid at Work (QCF)
A EFAW certificate is a Level 2 qualification and is not sufficient enough to teach First Aid.
