Well, some teachers will agree to a trial of more advanced work (not holding out hope for more interesting) if asked, at least here in the U.S.
It sometimes helps to bring in "worksheet" type material aimed at older children that your child has done at home.
Sometimes homeschooling is the way to go, particularly if your child isn't relativly even in his gifts.
My DS11 had similar reports in 2nd grade. You can try the "Well maybe he has a disability, I request in writing that you test him to see." route. Not sure what the laws regarding disabilities are in the U.K.
Whatever else, keep facilitation his further explorations at home, you aren't creating a problem, you are keeping him sane. I was quite confused about this at the time.
Best Wishes,
