Thrilled to report that I've finally received my BRP today! My FLR(M) renewal application was submitted in July and approved in December but it's taken an additional two months to get hold of my BRP.
I had updated my address with the home office while my application was still pending, about a month before my application was approved. Unfortunately it took them until January to process the change of address request (which would've taken a few days pre-Covid). That meant my BRP was sent to the old address.
I contacted UKVI 10 WD after the approval email to say my BRP hadn't arrived. I then had to wait a further 20WD to send a chaser request, since they didn't respond. They eventually sent me the consignment number and told me to contact TNT as they still had the BRP. Finally, after hours of waiting on hold and chasing them four times over the past two weeks, they've just delivered my BRP this morning.
So grateful this nightmare is over with until ILR in just under 2 years' time! Good luck to those still waiting - it seems things are moving a little faster now at least!
