Nannynick- I’ve done a little research regarding this matter and local authorities such as Surrey/Hampshire do not approve training.
I think it is best to research before joining a course and attend training with companies that are established and have been around for a while.
Local ones I’ve found such as Red Cross, St Johns, Surrey First Aid Training, I did a course with Tigerlily however I’ve found out it is a member of a trade body, does anyone know what trade body means??
