Thank you for the ideas.
The idea I was going for was simple - take an American wheat ale, sub in maris otter for enhanced maltiness, and ferment with a british ale yeast - all to just make it a bit more characterful. I do see that wheat (particularly torrified wheat) is a common ingredient in english pale ales. But thats not what I am going for.
According to all powerful google, there are at least a few beers classified as British what beers.

Specifically the article mentions
Hop Back Thunderstorm (5%). Classic British wheat beer style from an excellent award-winning Wiltshire brewery who also produce a Wheat Stout. A meeting place of British and Germanic styles according to Hop Back's Richard Harvey, though I would place it firmly in the British camp. The nose is a light and hoppy aromatic one, which is closer to traditional British ale, than Bavaria or Belgian wheat beers. It's a delicate straw colour and the palate produces soft malty, citrusy and refreshing flavours to be followed by a bitter mouth-drying finish which leaves you wanting more. With food the soft citrus and malt work well with seafood, especially fried squid. Bottle-conditioned from several supermarkets and also available in draught.
O'Hanlon's Maltster's Weisse (4%). Liz O'Hanlon describes this as a German-style white beer with an outstanding lemony taste. Unlike the Bavarian and Belgian styles, the hops are very evident (though not overwhelming), especially on the nose and in the finish. Once again, as is common for wheat beers, there's an initial soft maltiness but then there's a deliciously tangy, citrusy finish which I think owes a lot to the use of cascade and first gold hops, along with challenger which is noted for its fruitiness. Once again, ideal for fish (especially with chips!) and I would also suggest chicken and even partridge. Bottle-conditioned from Safeways and in draught.
I guess I'll give it a go and report back.
Thank you
