Security Clearance - SC - what is checked?

They do a full check of your internet browsing history based on your internet provider's logs too. So bear that in mind.

That's why I use my neighbours wireless network for that kind of surfing...

So if, hypothetically speaking, the permanent job required experience of product X and you had experience of product Y but knew you could pick up X no bother so got a bit 'creative' in the CV this would be found out?

No - the reference only asks if you know the person concerned, for how long and if you have any doubts about them (can't remember the exact details, but a business associate and I vouched for each other - perfectly correctly) the form I had to complete wasn't that detailed, so wouldn't have revealed any creative CV stuff.
