problem is because its an iPhone 6, and Apple's design requirements somehow insists on it, the glass and LCD are fused together. Thus, even though its possible to separate them and replace just the glass, no-one you can pay will do it since there is a high probability of cracking the screen while removing the glass...
here's an example with someone using a heat gun and something like a credit card :

So the short answer to your question is, no, you have to replace the entire screen. Last price I saw was about R3000 ....
Or, if you want to risk cracking the screen (which you'll probably have to replace anyway) you can DIY it since the glass only kit costs like R400 last time I checked.
Good Luck (Next time get a Nexus - queue the trolls )
