Understanding Revalidation — A Complete Guide for UK Doctors

Last updated: 5 March 2026

Revalidation was introduced in December 2012 and is now an established part of medical practice in the UK. Yet many doctors still find the process confusing or anxiety-inducing. This comprehensive guide explains everything you need to know.

What Is Revalidation?

Revalidation is the process by which the GMC confirms that licensed doctors are up to date and fit to practise. Every licensed doctor must revalidate, typically every five years, based on a recommendation from their Responsible Officer (RO).

The Five-Year Cycle

Your revalidation cycle runs for approximately five years. During this time, you need to complete five satisfactory annual appraisals and demonstrate that you meet the requirements set out in Good Medical Practice.

Role of the Responsible Officer

Your RO is a senior doctor who oversees your appraisal and revalidation. At the end of your cycle, they make a recommendation to the GMC. This can be a positive recommendation, a deferral (requesting more time), or a non-engagement notification.

What Happens If I Defer?

A deferral is not a negative outcome — it simply means your RO needs more time or information. This might happen if you’ve missed an appraisal due to illness, maternity leave, or other legitimate reasons. The GMC allows flexibility in these circumstances.

Supporting Information

Over your five-year cycle, you need to demonstrate all six types of supporting information at least once. These are: CPD, quality improvement activity, significant events, colleague feedback, patient feedback, and review of complaints/compliments.

Tips for Successful Revalidation

The key to stress-free revalidation is consistent, annual engagement with the appraisal process. Keep your portfolio updated throughout the year, not just before your appraisal. Seek feedback regularly. And don’t be afraid to ask for help — services like DAC exist specifically to support you.
