Gas hob clearances to adjacent wall/surfaces

Hi

Does anyone have a link to the up to date regs for Gas hob clearances to adjacent wall/surfaces?

I have 12 August 2014 regs, but document sates that it is uncontrolled, so could well be out of date.

This is what I have:

Basically, from what I understand the 'blue' is the exclusion zone for combustible materials.

Has this been updated, or does it still apply?

Thanks
