Hopefully this isn't such a stupid question!

Stupid questions tend to be those where either the information is
already readily available, or the questioner has been told the
answer once and keeps asking until someone gives the answer the
questioner wants to hear. Neither apply in this case.

I have a mains powered door bell, can anyone tell me if the voltage of the
wires at the bell push is low voltage?

Actually the 230V mains is low voltage. As other have said the
supply to the bell push is almost certainly an even lower voltage,
called extra low voltage. I have never come across chimes that
worked on low voltage. There should be a transformer near the bell
or in the consumer unit. If it is in the consumer unit it is
probably not a good idea to fiddle, unless you are sure you know
what you are doing.

My cousin has sent me a fantastic bell push (from America) but it does say
that the bell push should have low voltage wires, no greater than 16v. The
house came with this doorbell so I have no instructions!

As has been said, turn off the circuit before working on it.
Hopefully in 5-10 minutes you will have a bell push to admi-)
