Maybe before Goku fights Cell? It is kinda weird that if Vegeta indeed accomplished what Goku did he doesn't try to boost his superiority over his and actually remains at a corner fully certain that Goku is stronger than him. It would really be the only instance that someone has a technique/transformation/etc. yet isn't stated. Even Piccolo was remarked to be on a whole new level than before. Vegeta & Trunks? Nothing. And in the risk of sound like a broken record the only official word on this says Trunks & Vegeta didn't accomplished what Goku & Gohan did.
Well, when Goku says that he'll fight Cell first and asks Vegeta if that's a problem, Vegeta just nonchalantly replies this:

Context: after Goku says he’ll fight first
Vegeta: “Do want you want. Either way, I’ll be the one to finish this…”
So it's clear that he thinks he's powered up so much that he can defeat Cell, which Goku won't be able to do. It's only until after Goku powers up that he realizes the extent of his power, as the most Vegeta had felt from Goku before was his less-than-half power, which he didn't know was less-than-half because, obviously, he wasn't there.

Vegeta: “It drives me crazy, but I’ll admit it…Despite doing all that special training, I didn’t surpass Kakarot…Th-that bastard’s a genius…But Cell is 1 or 2 steps above even Kakarot…”
And Cell does mention that Vegeta and Trunks have become stronger, but they're still inferior in power to Goku.

So, just like Piccolo, they're mentioned to have become stronger than before. It's only slightly different in Piccolo's case because, straight afterwards, it's used as a point of humour that, no matter how strong Piccolo's become, it still won't do any good against Cell.

Goku: “Hey… Piccolo! Did you go in the Room of Spirit and Time?”
Piccolo: “Indeed.”
Goku: “I can tell! You’ve risen to an entirely different level.”
Piccolo: “…Why don’t you just be frank with me? I’ve grown stronger, but even, it won’t do any good against Cell…”
Goku: “…Yeah, it won’t do any good.”
Piccolo: “Hmph…You really were frank…”
What can be concluded from the whole thing is simply that Vegeta and Trunks didn't gain as much power as Goku and Gohan did. That doesn't have to necessarily mean that they didn't achieve Full-Power Super Saiyan.
