How to adjust UPVC front door

[itm2]

Our UPVC front door isn't closing properly because it is lop-sided. Viewed from the inside, the top left edge of the door catches with the frame when the door is closed, while there is an air gap of a couple of millimetres in the bottom left between the edge of the door and the frame.
Each hinge has a single allen key socket on the front, which doesn't seem to do much other than loosening the hinge in its housing.
Any hints for how I can straighten up the door?

Hi , thats a composite door . You need to remove the cover off the top and bottom of the hinge , then find something to snuggly fit over the pin you can see, ( a small socket should do the trick. Then loosen the Allen key in the centre of the hinge , that you've recently tried to adjust, as you do that you can turn the ' socket' which ever way you need to go to adjust the door. Hold it where needed on the socket and then retighten the centre Allen key

Thanks for the info. I've just had a look at the allen-shaped pin, and because it's inside the cylinder I don't have a socket anywhere near small enough to grip it. Any imaginative ideas for what I might use?

Not sure to be honest , as there is a special tool that normally comes with the door which we use. Maybe a pair of long nose pliers may be enough to hold it. If you can get someone to hold the door in the position you need to might be able to do it on just the centre Allen key , as it will move left and right too
