Hello Mikey,
It appears as this damage could be caused by possibly slugs, beetles or caterpillars. My guess is more towards slugs; as you are not seeing any pests when you are out looking during the day. You could try looking at night with a flashlight and maybe you could catch the culprit in action. The best time to catch them is usually around 2 hours after sun down; which you can hand pick them off and place them in warm salt water to kill them. I have also had good luck with setting out beer traps; bury a tuna can and fill with beer and place near the plants that have been affected.
Here is a pretty good article on some different solutions for dealing with slugs:

You may also want to check thoroughly under the leaves for any eggs, which may give more signs of what the actual pest may be, so you can better deal with the situation.
