Culture minister Michelle Donelan said on Tuesday the government would publish draft legislation soon, setting out proposals to ban conversion practices in England and Wales.
"The Bill will protect everyone, including those targeted on the basis of their sexuality, or being transgender," Donelan said in a statement.
Conversion practices, which may include extreme or harmful methods, are aimed at suppressing or preventing a person from being gay or existing as a gender different from the sex recorded at birth. A 2017 national LGBT survey people found that five per cent of respondents had been offered conversion therapy and two per cent had undergone it, with over half of it done by religious groups.
The British government said in 2021 it would introduce a ban on conversion therapy for LGBT people to prevent "abhorrent practices which can cause mental and physical harm", but later decided the ban would only cover lesbian, gay or bisexual people.
Donelan said on Tuesday the draft legislation will aim to cover transgender people as well, and that the government will ask for pre-legislative scrutiny of the bill by a joint committee.
Many campaigners have long called for a ban on conversion therapy, but others have argued that any ban should not outlaw conversations with clinicians or therapists helping people with gender issues.
"The legislation must not, through a lack of clarity, harm the growing number of children and young adults experiencing gender related distress, through inadvertently criminalising or chilling legitimate conversations parents or clinicians may have with their children," Donelan said.
Over two dozen health and counselling groups signed an updated memorandum of understanding last year, agreeing that "conversion therapy, whether in relation to sexual orientation or gender identity, is unethical and potentially harmful."
Separately, Britain said on Monday it would block a bill passed by Scotland's devolved parliament that makes it easier for people to change their legal gender.
