It's frustrating, ours took 19 months from memory for 820 grant and we had 98 separate documents of evidence (according to our agent we had more than quadruple most applicants). We also had no joint assets (I owned my own home, car etc before she moved here and adding her name to the deed was stupidly expensive).
It's very stressful, especially when you've done everything right, but hang in there. The dept is actually competent at their job, even if they seem slow. We watched some granted in months while we were waiting which made my partner anxious (I work in gov so I know things move at a different pace and don't take it personally there).
Hang in there, and whenever they ask for more info just send it in (also one thing we did was update our file as we waited, photos of events, trips, tickets etc which was kinda hard during the lockdowns).
