Have you looked at independent first aid providers? I know of a few fully accredited by ProTrainings, a first aid organisation like SJA. It’s a lot cheaper and it covers pretty much the same content.
I got my First Aid Plus through ProTrainings and also got a 3 Day First Aid at Work through being a volunteer first aid we at work.
I’m looking to do a 16 hour outdoor first aid qualification soon too.
Feel free to ask me any questions.
