LAA helicopters operate from Whitechapel but stay overnight at RAF Northolt. In May 2018, LAA used Helimed 27 as the duty callsign. Helimed 28 was only used if both helicopters were called out. 
At the 2022 Farnborough Air Show, it was announced that the two H135 airframes are due to be delivered in Sep and Oct 2024 respectively.
