Update:

Building Inspector came out from the local council and said that
although it was unlikely to fall down imminently, high winds or future
frost damage could bring it down and that Anglian should have known it
needed a lintel installed. Said the damage bricks could be drilled
out, replaced with similar, specially painted to match existing
weathered look.

Said that Fensa was essentially useless and only meant that the glass
was toughened or whatever required by the regs, not that it was
installed properly.

I called Anglian and told them about the BCO. They said a manger
would call me back and arrange to visit with a builder to see what
needed to be done.

I phoned consumer direct (the front end of Trading Standards these
days) and they said to give 'em two weeks written notice to put the
lintel right quoting Supply of Goods and Services Act 1982. They
also said the fact that they'd damaged dozen of bricks around all the
windows was basically tough **** -- maybe they could replace a few of
the worst bricks but if I object to it looking cosmetically crap, I'd
have to go to court and let a judge decide, which I think is pretty
appalling.

Most importantly they said I couldn't get any one else in to rectify
it -- I have to let the monkeyboys have a go first. Is that true??

As I may have mentioned, uk.legal.moderated ---

You will get the same calibre of legal opinion there as you do DIY here

Glad the BCO was unambiguous.
