CAP director Shahriar Coupal said: "Harmful gender stereotypes have no place in United Kingdom advertisements".
To justify the move, the Committee of Advertising Practice (CAP) has elaborated that stereotypes in ads risk contributing to "how people see themselves and their role in society", and as a effect can prevent people from social advancement.
The advertising regulator is banning the depiction of harmful gender stereotypes in advertising, saying they have "no place" in United Kingdom marketing campaigns.
The ASA's gender stereotyping project lead Ella Smillie told the Guardian that the organization doesn't see its role as social engineering, but rather reflecting the changing standards in society.
The Committees of Advertising Practice (CAP), which creates and maintains advertising codes in Britain, on Friday published guidance on depicting gender stereotypes ahead of new rules coming into force in June 2019. The proposals have been agreed by the Committee on Advertising Practice (CAP), which will also bin ads suggesting those that do not have a ideal physique are unlucky in love as a result.
The CAP also said that adverts that emphasised the contrast between a boy's stereotypical personality, for example, being "daring", with a girl's stereotypical personality, for example, being "caring", needed to be "handled with care".
Shahriar Coupal, the direct at CAP, has been cited as saying that: "Harmful gender stereotypes have no place in United Kingdom advertisements".
"Nearly all advertisers know this, but for those that don't, our new rule calls time on stereotypes that hold back people and society".
It will endeavour to prevent ads "aimed at new mums which suggests that looking attractive or keeping a home pristine is a priority over other factors such as their emotional wellbeing", while adverts will also be banned from indicating a person is not successful because of their physique.
Adverts may also be banned if they belittle men or boys for carrying out stereotypically female roles or tasks.
Ella Smillie, gender stereotyping project lead for CAP said: "The evidence we published a year ago showed that harmful gender stereotypes in ads contribute to how people see themselves and their role in society".
"What we're saying is there's certain types of ads which implies a certain rule or a certain behaviour can only be associated with one gender over the other, so an ad that mocks men for talking about their feelings or showing emotion might be problematic".
