I've had reasonably good experiences with Express and they tend to be my taxi firm of preference (but perhaps only because I have their number in my phone!) Nine times out of ten they have been prompt when booked but there have been a couple of occasions when they have forgotten a booking, which can be annoying obviously. They were very apologetic about it.
Some of their cars are on the small side (I've certainly seen a small Skoda about the place) , so do make sure you mention if you need a larger car (if there are four of you, if you have luggage, for instance).
Drivers are usually pretty polite which is good. They cover most of the area round Falkirk and don't think Linlithgow and Bo'ness are a million miles apart!
