Unfortunately we are currently in the perfect storm; Brexit, Covid and Procrastination (Brits leaving it until the last minute).
We got our residentia early last year. Our solicitor got us our NIE a few years back, but I’m told he got it within days. Our padron took the longest at 10 days from start to finish. We got a cancellation appointment for the Residentia in Murcia, so from start to finish (booking to our acceptance - getting the green card) it only took 3 days.
I would recommend getting a good Gestor, we used one for all aspects. Yes it’s costs money but saves lots of headaches.
We are in the process of applying for out TIE. Our Gestor got an appointment in 5 days, if you try it’s months. It’s not what you you know, but who. This is how Spain 🇪🇸 works unfortunately.
