Not fitting but I worked in the business for some years. There must be a trade supplier in Glasgow.
What sort of carpet are you fitting? If it's a traditional woven type you need the grippers which can be stuck or nailed depending on your floor type. When nailing into a wooden floor make sure you know where the water and radiator pipes are! Tufted or non woven types can be perimeter stuck if the area is not large, then the grippers are not needed. A kneekicker will also be required to fit a woven carpet to stretch it. You will also need naplock plates where it meets other surfaces in doorways etc. Copydex is good for treating cuts ends to stop fraying out.
It may look easy but I assure you it's not, I'd say get a pro to do it for you.
Edit: you may need to mastic the gap between the floor and skirting if you have one as airborn dirt from the wall cavity can cause soiling.
