You can try the bucket test for the pool, put a bucket or the like on one of the steps of the pool and fill the bucket to the same level as the pool, if the pool is self filling and it sounds like yours is you need to (as has been said) shut the isolator valve off or disable the auto fill in some way, then if there is a leak you will see the pool level going lower than the bucket level.
Pressure testing the drains and skimmer will cost around 120 Euro and is the fist place to look if you have a leak, as Jim has said you can lose water via the lights if you have them, if the transformer for the lights is lower that the pool light level you may find water around the transformer as the water travels down the conduit, it should be higher than the lights these day but its worth checking
