Thrown one together just now, keep in mind though that I haven't brewed it yet, so no idea how it'll come out. Feel free to tweak. Done for an efficiency of 82%. Target OG 1.040. Target FG 1.008. Target IBUs: 31.6 Tinseth. Target Colour: 22.4 EBC. Target volume into FV: 25 litres.
Mash: BIAB, 24.33L strike water. 90 minutes @ 66 degrees C. Mash out at 75 degrees C, raising of 7 minutes, held for 10. Sparge with 3 litres @ 75 degrees C.
Crisp Maris Otter 6 EBC 3400g
Crisp Black Malt 1339 EBC 40g
Crisp Crystal Malt 150 EBC 300g
Torrefied wheat 3.3 EBC 150g
Boil for 90 minutes
@90 minutes 12g Magnum whole hops
@15 minutes 1/2 Protafloc
@10 minutes 35g Fuggles
@10 minutes 23g Endeavour
Top up the FV with 6 litres of sanitary water. I've set it to use Mangrove Jacks M36 Liberty Bell yeast, but use whatever yeast you fancy really.
Hope it turns out ok for you if you do brew it. I've kept it simple, but feel free to add more hops at flame out/hop steep/whirlpool for more aroma and flavour. Also feel free to remove the black malt if you don't like it, I quite like the flavour it adds. The Crystal is optional too, but note that you'd need one or the other for colour.
Here's my version based on your recipe. Had to adjust it slightly due to lower batch size and different yeast, but added some sugar to target the same FG. Also kept the same amount of flavour hops and reduced the bitter hop to target the same IBU. Won't get a chance to brew it for a couple of weeks as I'll be heading overseas for a while, so if you do yours first, let me know how it turns out!
