I have had those Stellar pans for 11 years. On an electric hob, the handles don't get hot at all, and neither do the lids. But on a gas hob, they can get very hot, even though I don't let the flame 'lick' round the edge of the pan. To be honest, I don't like cooking on gas at all - I've burnt myself more often in a year of cooking with gas than in 10 years of cooking on electric.
I find they do, though not massively. I can hold them if I hold it at the end of the handle, though this isn't really that safe as it gives you less control, and makes the pan feel heavier. And it is hot enough that you don't want to be holding it for ages.
I have some with plastic coated handles and they are much better. They don't seem to melt or anything (and pans are handed down from my mum's old neighbour, so they have been in use a long time)
