my upvc door is filling with water which escapes through the screw holes which retain the locking mechanism,and leaking on the floor inside my house.Can anyone suggest where the water my be entering the door

most likely the top of the door. it may be entering there as the seal may be worn. replace the seals there available on ebay. try using a ladder and looking around the top to see if u can see any ingress of water marks and inspect the seals or any damage
