Thank you all for your help, I really appreciate it.
My mistake, it's actually the 45x45x45 Exo Terra tank that I have. I did think at the time that the dimensions I originally gave sounded a bit small!
I have those digital thermometers, think they're from Exo Terra too, which measure both ends. I'll turn up the temperature on the heat pad to start with.
I'll sort out a moist hide too. I do have a home made one from an ice cream tub in my larger tank. I'll also sort out the substrate as advised.
I must be doing something right with other healthy gecko as he's been perfectly happy. He probably now appreciates the place to himself!
