I know it was never taught when I was still at school... but that was because it was prevented by Section 28 of the Local Government Act 1988 (c9) until 2003.
"Prohibition on promoting homosexuality by teaching or by publishing material.
A local authority shall not -
a. intentionally promote homosexuality or publish material with the intention of promoting homosexuality;
b. promote the teaching in any maintained [at the public expense] school of the acceptability of homosexuality as a pretended family relationship."
That doesn't exist anymore, but there is nothing (that I'm aware of, at least) that says it has to be included as part of the curriculum (just that discrimination should not be tolerated). Because it doesn't HAVE to be taught, schools haven't bothered to change what they teach very much over the past few years, so it probably won't come up all that often in UK schools.
p.s. I see you're from Sheffield Harrison. I'm at uni there at the mo.
