Every nurse on the NMC register knows they need to revalidate every three years. But why three? Why not one, two, or five? And could that change?

The answer has roots in the NMC replacing the old prep system in 2016, comparisons with how other health regulators operate, and balancing patient safety with the administrative burden on nurses. And right now — with the NMC consulting on revalidation changes in September 2026 — the three-year cycle is being looked at again.

Here's why it's three years, how it compares to other countries, and what might change.

The Origins of the Three-Year Cycle

Before 2016, nurses and midwives followed prep (Post-Registration Education and Practice). Prep required you to maintain a portfolio of learning activity but didn't have the same structured submission process that revalidation introduced.

When the NMC developed revalidation, they followed the model set by the General Medical Council (GMC) for doctors, who also revalidate on a five-year cycle. The NMC chose three years for two main reasons:

  1. Patient safety: Three years gives the NMC a regular, consistent check that every nurse, midwife, and nursing associate is still fit to practise. Any longer, and the gap between checks would be too wide to catch concerns early.
  2. Evidence-based design: The NMC's research in 2014-2015 suggested that a three-year cycle struck the right balance — frequent enough to maintain public confidence in the profession, but not so frequent that it placed an undue burden on nurses who were already managing heavy workloads.

Why Not Every Year?

A one-year revalidation cycle would mean submitting a portfolio, arranging a reflective discussion, and getting confirmation sign-off every 12 months. For a workforce already dealing with staffing pressures and administrative load, that would be unsustainable.

The NMC registers over 860,000 nurses, midwives, and nursing associates. Processing revalidations for that many professionals every year would require a significantly larger regulatory operation — and the costs would be passed back to nurses through higher registration fees.

Annual revalidation would also mean you'd struggle to demonstrate meaningful professional development. One of the strengths of a three-year cycle is that you can show how your practice has developed and changed over time, not just within a single year.

Why Not Five or Ten Years?

Five years is what doctors currently have under the GMC. A longer cycle reduces the regulatory burden but increases the gap between checks. For nursing — a profession where practice standards, guidance, and evidence change rapidly — three years is considered the longest safe gap.

The NMC's 2026 review of revalidation is looking at whether the current cycle is still right, particularly as recent employer roundtable proposals suggested linking revalidation more closely to annual appraisals. This could mean the submission timeline stays at three years but with more frequent check-ins built into the process.

Ten years was never seriously considered. No healthcare regulator in the UK uses a ten-year cycle — it would be too long for public confidence and patient safety.

How Does the Three-Year Cycle Actually Work?

Your revalidation date is linked to your NMC registration renewal date. When you first joined the register, the NMC assigned you a three-year cycle. Each time you successfully revalidate, a new three-year cycle begins.

Within that three-year period, you need to meet the following requirements:

Your online application opens 60 days before your revalidation date. You cannot submit earlier than that.

Quick fact: The NMC estimates that over 95% of nurses successfully revalidate on their first attempt. The vast majority of issues come down to incomplete portfolios or last-minute scrambles — not clinical concerns.

Could the Three-Year Cycle Change?

Yes. The NMC has announced a full consultation on revalidation changes in September 2026. This follows the employer roundtable discussions and the launch of their new online portal.

Potential changes being discussed include:

Any changes from the September 2026 consultation would likely take effect from 2027, meaning most nurses would see new requirements in their next revalidation cycle.

How the Three-Year Cycle Compares Internationally

The UK isn't alone in having a three-year cycle. Nursing regulators in other countries use similar frameworks:

The Bottom Line

The three-year cycle exists for a practical reason: it's long enough to be manageable for working nurses but short enough to maintain regular checks on fitness to practise. It wasn't chosen arbitrarily — it was designed after research into what works for patient safety, the profession, and the regulator.

And with the NMC's September 2026 consultation on the horizon, now is a good time to understand why the cycle exists, what it requires, and how to keep your portfolio current throughout the three years — not just in the last few weeks.
