I have just had my extension wired up but it turns out the light switch has been wired onto same circuit as lower wall sockets. The light switch plate has a 3 amp fuse incorporated. I quickly spoke to the guy who was a subcontractor but he said he wasnt instructed to fit a dimmer switch and had no time to redo this job. How can I replace this with a dimmer switch ?

you cant.
the thing you are looking at is a fused connection unit, you must have one as the supply is a spur from the sockets.
how ever you can fit a dimmer after it.

connect it in series with the live supply AFTER the FCU
Switch mains off take cable from fcu to dimmer add new cable (same size) from dimmer to FCU connect in FCU as it was (On the load side)
at the dimmer you should now have 6 wires, 3 in 3 out
join the blue ones in a choc bloc, put sleaving on the earths and connect them to the earth terminal of the patress you just installed (if you have a metal dimmer run a short wire from the dimmer earth to the patress earth terminal.
tou should now have 2 brown wires not connected to anything left.
these go to the dimmer switch.
the dimmer switch needs to be suitably rated for the lights you wish to dim
