CPD hours explained: how many you need and how to prove them

CPD hours are the most argued-about number in professional development. Regulators set them, employers count them, and professionals worry about them - usually a week before revalidation is due. This guide unpacks what CPD hours actually measure, how many you need across the main UK professions, how to count them without inflating the total, and how to prove them without a last-minute scramble.

What a CPD hour actually is

A CPD hour is one clock-hour of deliberate professional learning. Not a training day of eight hours where three were spent on lunch and email. Not a conference where you attended one useful session and skipped the rest. The honest number is the time you were actively engaged in learning something that changed - or could change - how you work.

Most UK regulators split CPD hours into two categories, using different names for the same idea:

• Structured, formal or verifiable CPD: someone else set the agenda and there is evidence you took part. Courses, webinars, conferences, qualifications, in-house training.
• Self-directed, informal or non-verifiable CPD: you set the agenda. Reading journals, listening to relevant podcasts, mentoring, shadowing, reflective practice.

Both count. Most regulators cap the self-directed share at around half your total, so you can't build an entire year of CPD from podcasts.

How many CPD hours you need

The exact number depends on your profession and, in some cases, your role. Rough guide for the UK:

• Nursing and Midwifery Council (NMC): 35 hours over three years, at least 20 of which must involve participatory learning.
• Health and Care Professions Council (HCPC): no fixed hour target, but a range of activities and evidence of impact on service users.
• General Medical Council (GMC): no fixed hours, but appraisal every year and revalidation every five.
• ICAEW (chartered accountants): reflect, act, impact, declare - no fixed hour count, but activities must be recorded and available on request.
• Solicitors Regulation Authority (SRA): no fixed hours; the requirement is to identify learning needs and act on them.
• Teaching and FE / Skills: no single UK-wide number; Society for Education and Training members are asked for at least 30 hours per year.
• CIPD (HR): no fixed hours; members must reflect on impact annually.

Always check your regulator's current guidance. Numbers change, and some professional bodies count "days" rather than hours, which needs converting.

How to count CPD hours honestly

Three rules keep the total defensible.

Count active learning time, not room-time. An eight-hour conference day rarely gives you eight CPD hours. Strip out breaks, lunch, travel, and the sessions you attended out of politeness. Six is a more honest figure for a busy conference day.

Round to the quarter-hour, not the hour. Rounding up every activity by 30 minutes adds up fast and starts to look fictional at year end. A 40-minute podcast is 0.75 hours, not 1.

Log the reflection, not just the hours. An hour with a two-line reflection is worth more at appraisal than four hours with no notes. Regulators are increasingly interested in the impact of CPD, not the volume.

Proving your CPD hours at appraisal or revalidation

The scramble at revalidation is almost always about evidence, not learning. You did the learning. You just can't find the certificates and the reflections are in three different notebooks.

A single CPD log, kept up to date each week, solves this. For each entry, record: date, activity type, hours (structured vs self-directed), provider, and a two-to-three sentence reflection on what you learned and what changed. Attach or link to the certificate where you have one. That is the evidence pack, and it takes seconds if you build it as you go.

If you don't already have a system, our free CPD tracker gives you exactly these fields, splits structured vs self-directed hours automatically, and produces a read-only share link for your appraiser or professional body. It is free forever for individuals and stays with you if you change employer.

Common CPD-hours mistakes

Four recurring traps:

1. Only counting formal courses. A year of "one training day" leaves you short. Reading, coaching conversations, post-incident reviews and mentoring all count if you can show impact.
2. Bulk-logging in December. By the time you sit down, you've forgotten three-quarters of what you did. The log looks thin because your memory is thin, not because your learning was.
3. Chasing the number. Booking a random webinar the week before revalidation to top up hours convinces nobody, including you.
4. Not mapping to standards. If your regulator uses a framework, tag entries as you go. Retro-tagging 40 entries is unpleasant.

The one habit that fixes CPD hours

Fifteen minutes, once a week, to log what you learned that week. That's it. Do that and the CPD hour count takes care of itself, the reflections are worth reading, and the evidence pack is ready whenever your regulator, employer or appraiser asks. Start with our free CPD diary if you don't already have somewhere to log it.
