the battery charger i have is a cheap 6v / 12v switchable charger, it has no light or anything on it to say its charging, but seems to do the job, i have only left it in for a few hours at a time but wondered if it is safe to leave plugged in for long periods?

or should i get a proper 'optimiser' charger?

Get an optimate, thats what I use.
Can leave it on for weeks at a time.

If you're storing a bike, charge the battery until fully charged, then take the charger off.  Do that once a month.  Assess the charge state with a meter.

I would strongly agree to buy an "optimiser" I tried with a small 6v charger and "cooked" the battery and luckily only warped the cells could have been worse as it kept charging and "gassing" the battery luckily it was well ventilated!!!
