my girlfried has just moved house she has got a large hot water tank
which contains two immersion heaters.
Can we link these to a timer or do we need seperate timers?

Usually, one is to heat the top, to provide a limited amount of water for
economy reasons, whilst the second heats the whole tank.
Connecting them together, to a single timer, would obviously negate this option.

However, you can get timers specifically designed to cope with
this, and only use one element at a time, such as

You'll probably find the lower one is on the economy 7 circuit and is
already timeswitched. The top one is usually only used manually if you run
out of hot water.
