That's very likely.

The 1.0 Ecoboost has what's called a "wet timing belt" - normally, camchains run inside the engine in oil, cambelts run outside and dry. This engine, along with a few others, have a belt inside the engine in oil.

Normally, belts don't like oil, and start to break up quickly.

There have been problems with these wet belts, and 10yr/90k is definitely about right for them to start showing their face - if not a lot earlier...

No, they haven't "caused it" - but by catching it in time, they've saved her a VERY large bill. Could missing the service have meant it wasn't spotted earlier? Perhaps. Has it been serviced since then?

Do you know if a pump would normally need replacing after a new timing belt too? 

Which pump?  It's common practice to replace the water pump at the same time as (not after) the cambelt, purely because of the labour costs.  To change a cambelt there's a heck of a lot of dismantling, so it's the labour that costs the big money - the part itself is cheap.  Since you have to dismantle the same set of gubbins to get to the water pump, it makes sense to change it at the same time - a few extra quid for a new pump to save another shed-load of labour later on.

They've said it's the vacuum pump?

Lots of posts on other forums regarding problems with Ford Eco boost engines, particularly as they get older. (As above, "wet belt")....also some YouTube vids explaining why they fail....worth a "google". It's basically a design problem....
