@Badgerbadger22 Groundsure have lots of different types of searches that they do, I've never used them for a local search and didn't realise they did those so can't comment on that, but you can get local searches done by search companies (who do still check all the council's records) rather than doing an "official search" done actually by the council, if that makes sense.
Hope you have a bit of luck finally!
I'm the same with it not feeling real, I didn't with our sale until we exchanged so I'll probably be the same again. I'm trying to remind myself that at work the vast majority do actually end up completing on the day they've agreed so I don't need to be fretting about it until exchange, but it's different when it's for your own house!
