NHS.Despite the service's legal obligation to offer a first appointment within 18 weeks of a GP referral, on average, trans people are waiting 18 months for a first appointment, with some waiting as long as three to four years.These long delays mean teenagers are potentially missing the short window of time in which puberty blockers are useful.The Good Law Project is supporting a group of four transgender people, including two children, in cases against NHS England for failing to offer a first appointment within the legal timeframe.Among them is 41-year-old Eva Echo from Cradley Heath, West Midlands, who came out as transgender in 2017.
