If all else fails you could try a detector marker dye system:-
https://www.ebay.co.uk/p/Leak-Detection-UV-Dye-for-Cooling-Coolant-System-12-X-25ml-Bottle-Ring-RLD2/2070502472?iid=230723938073&_trkparms=aid=222007&algo=SIM.MBE&ao=2&asc=49481&meid=0ffc73bd935f4e85b811c7f4f5983f98&pid=100005&rk=5&rkt=6&mehot=pp&sd=401171372180&_trksid=p2047675.c100005.m2219
On the anti-freeze front, the LR recommendation is a 50/50 mix of Havoline XLC or equivalent. The system holds 13 litres, only 8 litres is drainable using the drain plug.
So once you get the leak sorted out, if all you have in the system is clean water then you're going to need 6.5 litres of anti-freeze to bring it up to the recommended spec.
Another advantage of anti-freeze even in warmer weather is that adding it improves the thermal transfer capability of the system so it can remove the heat of the engine to the radiator more efficiently than just plain water.

Probably you're core plug is leaking... Does she still start alright in the cold?

Maybe check the water pump and seals.
Previously I'd had an issue with the core plug, which got replaced, then I started losing water again, checked the core plugs, they were fine, checked plenty of pipes, all fine. Turned out the water pump and its seals were shot.
If it is the water pump, budget for around the £250 mark.
