See our projects section. There are a number of projects in there which wioll help you identify where the wires from lights go. Changing a light fitting is one

Thanks for replying so quick, I have been through the projects sections, but still not 100 %

I'm thinking the following
3 earth cables into the earth on the new fitting
2 black (neut) into the Neut on the new fitting
The black switched wire into the Live on the new fitting

the 3 red cables i'm stuck on !

ok mark the black on switch wire with red sleeve or tape,connect all reds to gether in the spare terminal ,then all greens these should be green and yellow ,solid green is the old colour and no longer complies with regs,these connect to the E terminal ,the blacks go to the N terminal ,and the one you should have marked with tape (switch wire) goes to the L terminal, this should have a minor works certificate because you have carried out work on the circuit and you need to confirm your continuity of the earth.
