Ok, while that looks a good, basic recipe in general, two questions spring to mind. Firstly: 14°C? I know Notto can go that low, but my memory of the Seven Sheds wasn't that it was a psuedo-lager or cream ale; more a pleasant pale ESB. Somewhere between 17-22°C would be more on target IMHO (and possibly a more hop-forward, or rather a less hop-muting yeast; S04 perhaps?) And what's with the Ella and Cascade? The Kentish Ale I had (granted, 2 years ago) only listed Goldings and Fuggles, if memory serves. Not that what you've posted would be a bad beer by any stretch, just not a clone, or even a ballpark emulation.
