Lots of engineering and physics students won't have further maths, and universities will have their courses set up accordingly.
With an A at A level maths, and A* for physics, his maths is obviously good enough.
He should have a look at universities and their open days to see what courses they offer and what they involve.
If he has any ideas of companies he might like to work for, or types of job then have a look at graduate recruitment websites and see what qualifications they are looking for.
Have a look at something like the Smallpeice Trust. They do lots of taster courses, although he might be too late for those, but also have a careers section on their website all about engineering.
If he decides to go for engineering, the most important thing is to make sure the course is accredited by the relevent institution. Also look at where major employers go for careers fairs (most will list on their websites).
There are some universities who run their course with a first year of general engineering and then you specialise. That can be good if he isn't sure what field he wants to go into (used to be Cambridge and Exeter, but don't know about now).
If he would be interested then look for somewhere that does the Erasmus scheme, where he could do part of his degree abroad. I did my disertation project in France, and friends went all over Europe (plenty of places don't ask for language skills either) - although a friend who went to the US had to repeat the credits when he came back to the UK after choosing to major that term in soccer...
I should say I am an engineer, so know less about going down the physics route!
Either option opens up all sorts of career paths though, not just in physics/ engineering. Accountancy and finance spring straight to mind, but lots of others too.
