I grow aubergines every year.
When I got the extra 1/2 plot on my allotment, I paid the bloke who'd left for his greenhouse, which has quite low eaves and a gravel floor. This makes it unsuitable for vine toms really, but ideal for shorter solanaceae like peppers and aubergines.
There are two f1 Moneymaker strains; I have found Moneymaker No.2 f1 to be reliable and profuse.
I averaged approx. 12 fruits per plant last year, plus some small ones.
I have "Gro-beds" which I bought from Marshall's, 6 fit neatly into an 8x6 greenhouse, and I have found that aubergines seem to do better in them than the ground, so them or a big pot would be best.
I think they like plenty of water, but also to drain, so they don't get root rot.
I live in Cheshire, so, outside they'd be marginal, and, you being quite close, would probably be better growing them under cover.
I've never had problems with blight, but powdery mildew and botrytis can be problems, so ventilate as much as possible.
If I can help with any questions, fire away.
I sowed my seeds a few days ago.
That variety:
Aubergine Money maker No 2 F1 crops more reliably outdoors than most aubergines. Early to crop and high yielding, the fruits are black and semi-long - just the job for making a perfect moussaka.
