it used to need topping up about every 6 months now its every couple of days there is no dripping from pipe that goes to out side wall and can t see any from rad valves if there is a leak would it be from the central heating pipes only
gt under the floor and have a look for a leak. if the expansion vessel was faulty the water would be coming out of the relief pipe.

it could be your expanson vessell, it is the large red vessell at the back of the boiler, unscrew the black cap depres the pin for a second,if there is water present replace,get a gas safe reg installer as it is a bit of ajob
