Hi, check the water seal in each of the traps below the sink/basin wastes also check to see if an "Air Admittance Valve" has been fitted to the soil vent pipe if it ends at the same hight of the highest window, if the vent pipe stops inside the loft, this will need to be rectified. With the traps, it is possible that the water level is not being maintained to form a proper seal. Also make sure that an old waste pipe has not been disconnected and left open allowing foul smells to vent back into the property, as for the toilet pan, make sure that the pan connector is making a good seal and not leaking from the pan end as well as the end that connects to the waste discharge pipe...hope this helps.
