Hi X.
Though I am nowhere near Manchester it really is very easy to change the front bumper... There is one self tapping screw on the front of each side wheel arch and a row of plastic pegs along the top and underside of the bumper - just pull out the middle of the button on each to remove - take the top centre one out last while you support the unit ... just watch out for the wires to the foglamps if fitted, and the outside temp sensor which is clipped to the bumper
