Well there is a growing Indian population so that might skew the statistics on home cooking lol.
Anecdotally, by far the worst home cooking I’ve had was at the hands of a British couple; tasted like simmered dish water.
There's actually an Orwell essay about this.

The thing I find odd about British restaurants is that all the Japanese chains (Wagamama, Itsu) have names that are so dumb it's like they're actively trying to be offensive.
The exception is "Chinese takeaway", which is actually as bad as the stereotype.
