My completely uneducated suggestion would be any with a certification. If it's just for the odd trackday, I wouldn't go too mad. Mine is the ex-wife's helmet that she used when she had scooter for a short while. But the visor is free of scratches (not that I would use it in a closed car) and it's a good secure fit.
Just try some, how far are you from Demon Tweeks, don't they have a place in London somewhere? I'm guessing they could advise on something safe and reasonably priced.
Edit - they don't have a place in London, but good mail order. If I was buying now, I'd go for an open face, maybe a Bell Mag 1 open face. Less claustrophobic, but a closed face could be used if you ever go karting or such -like.
OMP Star is very reasonable £50, no cert on it but aimed the occasional trackday user. Might snap one of those up myself

"I look at it like this. Owning an M5 is kind of like dating a slamming hot big-t...ed blonde, who is a pain in the *****, drains your cash, but screws like there's no tomorrow. Owning a Honda Civic or the like, is akin to dating a girl who is fat, ugly, smells a bit where she shouldn't, is a cheap date and doesn't screw at all (you don't mind). So yeah, I'll take the blonde."
