Only those who lack of knowledge in the route of getting PEPC says its difficult, don't bullshit the masses, its pretty easy with the right experience & nature of work you're doing.
Does having PEPC makes you more employable? Not really..There are some PEPC whose out of jobs now. Thats why I didn't bother even to proceed with tier-1 Ir application what more tier-2 (PEPC). PEPC is useful if you're working in consulting firm or running your own consultation firm. 80% of the time, in contracting line, not useful at all.

Plus who wants to hire an engineer with PEPC when you have loads of normal engineers who can multitask & having dynamic experience not just in engineering works, but tendering & management.

Out of context, I did civil engineering in uni & being doing civil engineering related works > 10 years now and slowly running own business together with my sister which is an accountant with ACCA.

You know what is harder? Making money.
