Thank you,
I've been following timelines, and in Im in Kent. Seems that people on the board that submitted the same time that I did ( august), received their permits the same week I received my letter (early Nov), so that reinforces the idea that they do them in bunches.
How long it takes from here, we shall see. Its been 3 weeks since Ive submitted the additional info, and the lady requesting it, Gia, was very polite and helpful when i spoke on the phone to ensure that she did receive them to move the process forward.
