The CISI Investment Advice Diploma is completed with three exams: two compulsory core units, UK Regulation & Professional Integrity and Investment, Risk & Taxation, plus one technical unit of your choice. CISI lists the technical options as Derivatives, Securities or Financial Planning & Advice. Ofqual regulates the qualification on its Regulated Qualifications Framework as the CISI Level 4 Diploma in Investment Advice, which sits at Level 5 on the European Qualifications Framework.

Then Investment, Risk and Taxation, the second compulsory core unit, also 80 questions in 120 minutes. Then one technical unit chosen from Derivatives, Securities or Financial Planning and Advice.

The Diploma is the standard route for people giving or supervising regulated investment advice in the UK, which is why firms in wealth management, private banking and financial planning treat it as the benchmark rather than as an optional extra. CISI puts the total qualification time at around 426 hours across the three units, so it is a materially bigger commitment than a single Level 3 award and should be planned across months rather than weeks.

The three units

Two of the three are fixed. The third is where the qualification adapts to the job you are actually doing.

Unit Role in the Diploma Questions Time
UK Regulation & Professional Integrity Compulsory core 80 120 min
Investment, Risk & Taxation Compulsory core 80 120 min
Financial Planning & Advice Technical option 80 120 min
Securities Technical option 100 120 min
Derivatives Technical option 100 120 min

The two core units carry the regulatory and technical foundation every adviser needs: one covers the rulebook, ethics and financial crime, the other covers asset classes, risk, tax and the advice process itself. Neither can be substituted.

Which technical unit should you pick?

Financial Planning & Advice is the natural choice for anyone heading into advice, paraplanning or financial planning. It is a pensions and protection paper in practice: Retirement Planning and Retirement Solutions are 36 of its 80 marks, and Financial Protection adds another 19.

Securities and Derivatives suit people whose work sits closer to the markets than to the client, and they are the same named units that appear in the Capital Markets Programme. If you are choosing one of them specifically to complete the Diploma, confirm the unit code with CISI when you book, since the same paper name can appear in more than one qualification and it is worth ten seconds to be certain the sitting will count.

One provision is easy to miss and worth money. CISI states that holders of an RDR compliant qualification can add additional specialist areas by passing the appropriate technical unit without completing the core areas again. Exemptions from certain units are also available, so if you already hold a related qualification, check the exemption list before you pay for a paper you may not need to sit.

What order to sit them in

There is no prescribed order and the core units can be taken either way round. In practice most people start with UK Regulation & Professional Integrity, because the regulatory framework, conduct rules and ethics it covers give context to everything in the other two papers, and because it is the unit most likely to be reused elsewhere.

Investment, Risk & Taxation is the sensible second paper. Its tax content is the most perishable material in the Diploma, so sitting it while your knowledge of current rates and allowances is fresh is worth more than sitting it last. Leave the technical unit until you know which role you are heading for, unless your firm has already decided for you.

How long the Diploma takes

CISI puts the total qualification time at around 426 hours across the three units. That is the figure to plan against, and it is worth splitting honestly: the two core papers are the bulk of it, and the technical unit is the lighter end only if you pick one that matches work you already do.

At six hours a week, 426 hours is well over a year. At twelve, it is closer to eight or nine months. Most people sit the units one at a time with a booked exam date in front of each, which is the only scheduling method that reliably works, because an open-ended plan for a 426-hour qualification quietly becomes no plan. Book the first paper before you start reading for it.

Where else these units count

UK Regulation & Professional Integrity is the broadest-reach paper CISI runs on the advice side. Besides the Diploma it appears in the Level 4 Certificate in Investment Management and in the Level 6 Diploma in Investment Compliance, so a single sitting can serve more than one route. That makes it the unit to start with if you are not yet certain which qualification you will finish.

Where Passkey fits

Passkey covers all five units listed above: both compulsory core papers and all three technical options. Whichever route you take through the Diploma, the practice bank, the timed mocks weighted to each paper’s real element split, the study notes and the flashcards are already there, and one payment of £59 covers every supported exam for 90 days rather than one paper at a time.

Passkey is an independent study tool. It is not affiliated with, endorsed by, or accredited by the Chartered Institute for Securities & Investment, and it does not replace the official workbook. The qualification comes from CISI.
