The Basics of ISO Consultancy Earnings

ISO Consultants help businesses implement, maintain, and improve their management systems to comply with International Organisation for Standardisation (ISO) standards.

Their expertise is crucial for organisations seeking certifications like ISO 9001 (Quality Management), ISO 14001 (Environmental Management), ISO 27001 (Information Security), ISO 45001 (Health & Safety) or ISO 13485 (Medical Devices).

But how much do they earn? Here’s a quick snapshot:

Employment Type	Average Annual Earnings (UK)	Average Annual Earnings (US)
Freelance ISO Consultant	£50,000 - £100,000+	$75,000 - $150,000+
Employed ISO Consultant	£30,000 - £65,000	$50,000 - $90,000
Senior Consultant/Director	£70,000 - £120,000+	$100,000 - $200,000+

These figures are just the starting point. Let’s dig deeper into what influences these numbers.

What Influences ISO Consultant Earnings?

ISO consultant income isn’t one-size-fits-all. Your earnings depend on several factors:

a) Specialisation

Not all ISO standards are created equal.

While ISO 9001 remains the most widely implemented standard, niche standards like ISO 27001 (Information Security) or ISO 13485 (Medical Devices) often come with higher pay.

Why?

Because they’re in demand and require more specialised knowledge.

b) Location

Geography plays a big role. For example:

• UK-based ISO consultants often charge £500-£800 per day.

• In the US, daily rates can hit $1,000-$1,500.

• Consultants in emerging markets like India or Southeast Asia may charge less but work on higher volumes.

c) Experience

Your track record matters. Entry-level consultants may start at around £25,000-£40,000 per year, while seasoned professionals can earn well over £100,000 annually.

d) Client Base

The size and type of your clients affect your income. Large multinational corporations with complex requirements pay more than small businesses looking for basic certification.

e) Business Model

Freelancers often charge higher daily rates but may have less consistent work. Consultants employed by firms enjoy a steady income but typically earn less than their freelance counterparts.

Job Security	Low	High
Perks (e.g., pensions)	No	Yes
