AC systems degrade with age. Possible leak sources are any connection point (couplings), hoses, anyplace a hose or component can physically rub against something else and wear through and just general failure of components. There are multiple ways to check for leaks. The best way is with an electronic "sniffer" which detects the presence of Freon. The system is evacuated and charged and with everything up to pressure the sniffer's wand is directed at suspect points. It emits a tone which increases in intensity when detecting Freon. Once located, the leak is fixed and rechecked.
Another way is to add Freon which is colored with a dye. Leaking points are more visible with the presence of the dye.
A third way (one of my favorites) is with soapy water. A detergent/water solution is sprayed or dabbed onto suspect points. Leaking will show up as bubbles.
The receiver dryer removes any trace bits of moisture within the system. It usually includes a filter to remove any small particulates. It is critical when servicing a system that has been exposed to atmosphere for any length of time to replace the dryer. If not replaced, newly installed compressors can fail due to moisture and debris in the system.
Make sure you take your car to a competent shop.

When a compressor leaks it's virtually always the shaft seal. Some are replaceable, some are not. Most modern ones are not, at least not ecomomically.
Whenever there is a mechanical failure in the AC system, swarf can pollute the receiver which also does duty as a filter for the system. For that reason, it is always necessary to replace the receiver. Additionally, whenever the system pressure leaks down to zero, moisture can enter the system, necessitating the replacement of the dryer. The dryer is usually part of the receiver.
The compressor will be the more expensive component on most systems. The receiver/dryer won't be cheap but it won't be as dear as the compressor. You're looking at several hundred quid, I'm afraid.

On an older car ,usually the compressor shaft starts leaking first.It could still be any mechanical connection with an o-ring seal,or a leaking hose.

Have the mechanic do a leak test
a special dye they run through the AC system to find leaks.
This might save you 100's of $$$$$

on any car or truck, the pressurised hoses, are reinforced rubber, with swedged on steel fittings. Vibrations and the movements of the engine, will eventualy stress some thing and cause the leak. Take it to some one you know, and see what he thinks.

Go to any mechanic shop and tell them that you want them to put dye inside the ac.The parts probably would not be expensive to repair or change...

Faulty piping or corrosion.
