Pretty straightforward to fit. Make sure you put some polythene under the 5mm underlay as any moisture will buckle the boards.
I always remove the skirting boards and replace if nailed or if they have been glued with use no nails glue you can normally reuse them. IMO it is much neater doing this than using the edge beading.
Leave a 6mm gap all the way round for expansion.
They do last a reasonable length of time, but are easily water damaged, especially from wet shoes etc, so I would recommend the green waterproof for a hall, bathrooms, cloakrooms and kitchens. If you drop something heavy it can damage the board and heavy traffic with shoes or cat and dog claws can over a period of time scratch the plastic top layer.
If you have radiator pipes that go into the floor, then drill a hole bigger than the pipe to allow an expansion gap and then cut from the end of the board to the hole at a 30 degree angle on both sides. you can then push and glue the piece in tight with almost unnoticeable joints. You can get pipe covers to hide the expansion area. But last time I did this I made my own where I couldn't get any to exactly colour match, with an offcut and a hole saw to cut out a washer and then carefully removing most of the wood to leave the laminate, and then cutting from the centre hole to the outside, this was flexible enough to go over the pipe.
IME it is not as hard wearing or damage proof as a solid wood floor and where with a solid one you can sand it and reseal with a laminate it is time to replace it. But there again solid wood flooring is considerably more expensive.
The modern no-glue self-clamping joints are so much easier than the old straight joints where you had to use ratchet strap clamps and glue them.
