Hi
I think it was me you were talking to! I was controlling the Lyd sector at the time and Terminal Control ran out of levels at Biggin without giving us much notice and we had quite a few Heathrow inbounds which we needed to slow down as quickly as possible to avoid any en-route holding.
If I remember correctly, I was unable to give you initial descent as there were several other high level aircraft just below you which I needed to vector out of your way first, and yes, this ended up with you being high.
At the time the RT was very busy and while I obviously wanted you to make the level and slow down as best as you could, I didnt have the time to fully explain myself (make the level then reduce speed etc). Having said that I didnt realise that deploying the speed brakes means your minimum speed increases so much.
Thanks for posting, I definitely learnt something today! Feel free to PM me if you have anything else to add!!
