my dad owns a desert rally team called RallyRaid UK. and all our custom built rally cars run buckets and harnesses (obviously) but they are all road legal.. and fully mot'd with cages harnesses and fixed bucket seats. i don't think there is a law, so long as they are all fixed in correctly, and for obvious reasons i would go and have my car mot'd soon as you've put them in, so that your mot says mot'd with different seats and harnesses in case you have an accident, then there's no way of your insurance bullshitting about your seats...
