The ADI Code of Practice is the professional standard every approved driving instructor is expected to follow. From late 2026, the DVSA is replacing the current voluntary code with a mandatory one. In short, agreeing to it is about to become a condition of being on the register. Below, we explain what is changing, when it takes effect, and exactly what you will need to do.
What Is the ADI Code of Practice?
The ADI Code of Practice sets out the professional standards expected of driving instructors. It covers how you treat pupils, how you run your business, and how you conduct yourself day to day. The DVSA agreed it with the industry through the National Associations Strategic Partnership (NASP), and it applies across England, Scotland and Wales. Until now, it has been voluntary. Many instructors already follow it closely, because it reflects good, honest practice.
What Is Changing: Voluntary to Mandatory
The headline change is simple. The existing voluntary code is being replaced by a mandatory ADI Code of Practice. In other words, following it will no longer be optional. This is a significant professional standards update, and it affects everyone on the register. The DVSA has signalled the change as part of its wider work to raise standards across driver training.
When Does the Mandatory ADI Code of Practice Start?
The new code is expected to come in between late 2026 and early 2027. Exact dates can shift, so treat this as the current plan rather than a fixed deadline. Always confirm the latest timing on the DVSA’s ADI Code of Practice page. Checking the source directly is the safest way to stay current.
When You Must Declare You Have Read It
Under the mandatory ADI Code of Practice, you will need to declare that you have read and agreed to it at key points. These are:
- When applying to become an instructor
- When renewing your registration
- When applying for a trainee licence
So the code will touch every stage of your career, from first entry to ongoing registration. Build time into each application to read it properly, rather than ticking a box in a rush.
What the ADI Code of Practice Covers
The code is built around four clear sections. In summary, it sets standards for:
- Personal conduct: behaving professionally, complying with the law, keeping clients safe, avoiding discrimination, and using social media responsibly
- Business dealings: accounting for money paid in advance, giving clear terms of business, recording pupil progress, and advising fairly on when to book a test
- Advertising: promoting your business clearly, fairly and without misleading claims, including any claims about pass rates
- Conciliation: dealing with complaints promptly and following a clear resolution process
For the full, current wording, read the code in full on GOV.UK. The official text is the only version that counts.
What This Means for Instructors
For most good instructors, little will change in daily practice. If you already work honestly and professionally, you likely meet the code already. The real shift is formal accountability, since agreement becomes a condition of registration. Treat the change as a prompt to review your own practice, your pricing, your terms and your record-keeping. A quick self-audit now beats a scramble later.
Mandatory ADI Code of Practice: Quick FAQs
Is the ADI Code of Practice compulsory now?
Not yet, but it is becoming so. The current code is voluntary. From late 2026, a mandatory ADI Code of Practice is expected to replace it, with agreement required to join or stay on the register.
Do existing instructors have to agree to it?
Yes, in practice. You will need to declare you have read and agreed when you renew your registration. New applicants and trainee licence applicants will declare at their application stage.
Where can I read the full code?
