Only going to give my honest opinion here. To be fair they have done a good job this far, I have a positive Skills Assessment - I am a UK qualified Spark, 17th edition, 2391 - mainly commercial but a bit of house bashing I had lots of periods of employment and self employment and to be honest it was an absoute nightmare getting stuff together but they did it for me. I call it as it is. At the moment I am stoked. If this changes I will be the first to have a moan up but I am very happy right now and I bet you don't read that that often on the forums, someone actually happy.
If anyone is in the same boat as me, ie UK spark wants any advice for the skills assessment let me know and I will do my best to help you.
