Take off lid and fascia, lay on its back and undo screws at top and bottom of front panel, open the door and undo all the screws visible bar the door hinge. Remove door panel and lock, you should be able to slide new belt over front of drum and edge it down till it lines up with the 'wear line' of the old belt. When it's here it's a good idea to tape it into place as best you can. Stretch the bottom of the belt over the pulley on the motor, a professional tool is available from Hotpoint but is nigh on useless so don't waste your money. If struggling, and you will, find something to lever it with but be carefull not to damage the motor. Once on reassemble the reverse of stripping. Good luck, and don't forget to disconnect from the mains!
