I'm from the UK too, i actually changed my name by deedpoll a year before starting HRT. My birth name was unisex anyway. But my other half hasn't changed her name yet and in about 6 weeks is going to start HRT. *Shrugs* they mainly just wanted me to present myself feminine first, then again i changed mine online, My birth cert hasn't changed yet as i have to reapply with the GIC as i missed an appointment due to illness.
