My block paving has been down about 18 months the blocks sit a little higher than the edge course can I run the wacker over it again to try and level it out a bit more?

You're unlikely to get much movement after this length of time. Just how high are the blocks? If it's more than 3-4mm, you may need to lift them, re-screed removing a scraping of sand, and the re-lay.

could be as much as 5-6mm in places, but there's no chance of me taking them up and re-screeding, it does bother me that much One of the blokes that came round to quote for the patio suggested giving it a whack, so i thought i would test his theory with the pros.
The bloke who laid the block's wasn't use to laying against concreted in edgings, he just put a fillet of 3:1 grit sand cement mortar against the the last block when he laid and whacked the drive he would be normal be laying.

The 'bit of mortar behind the outside blocks' is a real cowboy tactic. Please kick this eejit in the 'nads the next time you see him.
If he struggled with the concept of concrete bedded edge courses, it's a fair bet that he allowed the concrete to spread at the 'front' of the block, which causes a problem known as "differential settlement" and is a likely reason for why the blocks adjacent to the aforesaid edge courses are high. If this *is* the case, then re-wackering won't do much except damage the blocks as they are, effectively, sat on that concrete and there's nowhere for them to go.
In such cases, lift and re-lay is the only viable option.

Sorry to go off topic slightly but talking of edging courses what do you reckon of this.
I got a feeling comments won't be favourable?

The price tells you all you needs to know. 21.58 quid per metre compared to what? a couple of quid for concrete?
And it's a bugger to form sweet curves using these systems.
