How to become a locum psychologist in the UK

A locum psychologist covers clinical work on a session-by-session basis for the organisations that need them, as a self-employed professional rather than a salaried employee. This guide walks through everything you need to do to start, in order, and the common pitfalls that catch people in their first year.

1. 01

   HCPC registration under the right protected title

   Psychologist titles are criminally protected: Clinical Psychologist, Counselling, Forensic, Educational, Health, Occupational, Sport & Exercise, or generic Practitioner Psychologist. Register under the one matching your training. Using the wrong title in marketing is prosecutable.

2. 02

   Obtain BPS Chartered status (CPsychol)

   Separate from HCPC. BPS Chartered status is expected in most senior locum roles and required for some referrals (medico-legal, expert work). Each division has its own CPD expectations, typically around 16 hours/year.

3. 03

   Pick your income mix

   Four common streams: NHS agency (capped framework rates, PAYE), private self-pay CBT (£90–£160/session in London), EAP network contracts (Vita, AXA, Onebright, Health Assured – fixed lower rates), medico-legal expert witness work (£1,500–£3,500/report plus court days). Most established locums run two or three of these.

4. 04

   Register with ICO for data protection

   Anyone processing patient data outside an NHS role must register with the Information Commissioner’s Office. The fee is £52/year for sole traders (Tier 1, ico.org.uk/for-organisations/data-protection-fee), and the maximum penalty for failing to pay or notify is £4,350. Register before your first private client.

5. 05

   Build formal clinical supervision

   HCPC standards and most professional indemnity policies require documented clinical supervision. Keep contracts signed and supervision logged. Indemnity insurers can void cover if you can’t evidence it.

6. 06

   For medico-legal: Bond Solon + referral network

   Bond Solon expert witness training is the minimum standard for court-acceptable reports. Join the Expert Witness Institute and build relationships with 3–5 solicitors’ firms in your area. Forensic and Clinical Psychologists dominate this niche – it’s the highest-margin work in the profession.

7. 07

   Plan for tax status by income stream

   NHS agency work is PAYE / umbrella. EAP contracts are usually self-employed per-session. Self-pay private practice is sole trader or Ltd Co. Educational Psychologists leaving LA roles often take commissioned block work as self-employed contractors – a distinctive feature of EP locuming.
