Honest answer: yes — but not for everyone, and not all certifications are equal. Here's what the data says about salary impact, career progression and whether it's the right move for you.
The numbers are genuinely strong. In the UK, Green Belt holders typically earn £6,000–£10,000 more than peers without certification. Black Belts often see £14,000–£22,000 uplift.
Beyond salary, LSS certification signals something employers value: you can identify problems, gather evidence, find root causes and implement sustainable solutions.
It's not worth it if you're in a role where you'll never use it. A certification sitting on your CV unused doesn't help you. The value comes from applying it.
It's also not worth paying thousands for a low-quality online certificate mill. Some providers charge £2,000+ for courses with no practical project requirement.
