Interesting, I thought I would need a 650w PSU minimum.

550W is fine for that setup.

Also it needs to be a good 550W PSU as above, not a nasty cheap one that cannot output its rated wattage/amps, thus thats why some manufactures play safe and suggest a slightly higher wattage PSU to account for the junk PSUs on the market.

I am going to go for the Seasonic, any reason not to?

I would get seasonic 650w for £10 more than the 550w.

Makes sense to me for £10 extra.

Seasonic built with a 7 year warranty based on the Focus Gold although this unit is only semi modular. There is also an Antec rep on the forum (Ace Modder) should you have any issues.

PSU has arrived. There are two PCI-E cables both with a dual connection. Should I use two cables for my 1080Ti or can I just use one cable and both connections?

Eithers fine, but two cables going to the two sockets looks nicer if you can get them to sit and bend the same.
