When you go to Halfords get a bulb a bulb holder and some wire (or a multimeter tester) and remove the single spade wire in the starter Solenoid connect ont to one side of the bulb holder to that wire and the other to ground try pressing the starter switch just to see if you have a current through that wire if you have it could be a Solenoid problem.

The other thing you could do is with the starter switch pressed in give the starter a sharp tap with a hammer, if the Solenoid is sticking this is a good way of getting it to work again.
