It depends. Usually local councils' websites are purely terrible.

DVLA is mostly very good, I'd say. Especially when dealing with vehicle registration, ownership change, taxing etc.

HMRC is in a category that I'd call "scary". Their website is nice and all but if you ever get locked out of their mobile app for confirming identity (or you delete it by mistake), it's really hard to fix the issue. This is connected to the fact that UK has no national ID card so they use various heuristic to confirm your identity.

UKVI is probably the worst as they don't offer a consistent experience. You can tell that some of their websites were developed in early 2000's and never updated.

UKVI has been driven for years by doctrine of "hostile environment".

Making the page (or their services) work well is in contradiction to the goals set by management.
