I have 6 years to make a claim.... I am making a claim with that 6 year period. Am I not?
Not trying to sound rude. Lol it's a serious question
You have 6 years to make a claim regarding an item you claim to be faulty at point of sale. Within 6 months of sale they have to prove it wasn't, after 6 months you have to prove it was.
That's not the same as something breaking from wear and tear, misuse, accident etc. within 6 years of purchase. SOGA is not a 6 year warranty in disguise.
If you want to pursue SOGA then you'll need to assert at some point how or why you believe the item was faulty at point of sale. Having used it extensively for 3 years without issue, this could be hard to convince them or a judge/barrister of.
