What I did and I'm just wanting to check that this was a legitimate
thing to do was to use a 15amp chocolate block to combine the mains
cables together (3 live into one and 3 neutral into another) I then
got some ring mains cable from homebase and used a few inches of
this to connect the chocolate blocks to the feed of the fused spur.

Is this ok?

Don't see why not - so long as you tightened up the screws properly!
