Complaints received from the public by the Commission included the provision of binders to young persons under the age of 18 without parental knowledge and/or consent. The inquiry has therefore considered this issue further. It has not considered the provision of binders to parents and carers who requested them on behalf of their children or those in their care. In a statement dated 27 September 2022, the Metropolitan Police confirmed that supplying a binder to a young person was not a criminal offence.
This is the Met Police page about breast ironing:
https://www.met.police.uk/advice/advice-and-information/caa/child-abuse/breast-ironing-flattening/
Breast ironing (also called breast flattening) is when young girls' breasts are damaged over time to flatten them and delay their development. Sometimes, an elastic belt, or binder, is used to stop them from growing.
Although there's no specific law within the UK around breast ironing, it's a form of child abuse
So it's not a criminal offence, but it is considered to be child abuse. Also, the Met Police page is clear that parents or other relatives are involved in administering this abuse, so why is it not considered abusive when a parent is involved with obtaining these devices from Mermaids?
