Engine temp not registering, engine light on

[TickTock]

Is this most likely to be the thermostat?

Coolant - levels checked and ok.

After small journey engine fan on. Guess thermostat must be working for the fan to kick in?:S

Thanks for any advice.

Coolant temp sensor would be more likely.

Maybe a daft question but is it ok to drive with fault?

I will soon have a spare brand new coolant temp sensor, if you need one.

The thermostat does not activate the cooling fan, the temp sensor does.
Check the connection under the thermostat housing, it might be loose/corroded...
If the check engine light goes on when cold it means there is a problem with the sensor, you can drive but you run the risk of overheating the engine in case something goes wrong (ie broken hose, low coolant level, etc).
Get it checked asap mate.
