How often should this be changed?

No official interval or even a recognised sensible time. It's more a case of the chain and tensioner start making a racket over time; at the point it annoys the owner enough - its time to do it.
I'm reliably told they don't tend to break on the mk5, just make a noise. Its the mk6 with a totally different set up which is the main culprit for snapping chains and I reckon a lot of the horror stories of chains snapping on GTIs around 2011/12 onward has back filtered into the mk5 community.

Ok I'll have a listen to mine then its on 111k at the mo but seems to have been looked after when I changed the HPFP piston it was like brand new:-)
Thanks F00gle

@rich83 I did this job a couple of weeks ago and wanted to say thank you for your excellent DIY - doubt I'd have managed without. Can't believe how much better the engine sounds now, all I can hear is the injectors and fuel pump firing. No more tractor noises at idle any more...
The only comment I have is that I could not rotate the engine from the inlet cam lobe - the T10020 tool just started bending and I didn't want to force anything. In the end I rotated the engine from the main crank pulley accessed through the driver's side wheel well.
The chain itself didn't have any signs of stretch, but I replaced it anyway. The tensioner on the other hand was still intact but definitely on its way out. The top plastic wear plate had a hairline crack running through the middle and the bottom plate was heavily worn from the chain. If you're like me and at ~120,000 miles and it hasn't been done before, I would seriously consider getting it done.
