A force can pay once for a group of officers studying for the National Investigators' Examination or the NPPF sergeants' and inspectors' legal exams, and each officer gets full access to all three revision spaces.
The product
What Police Law Prep is
Police Law Prep is a £15 a month revision app for the National Investigators' Examination and the NPPF sergeants' and inspectors' legal exams. I built it and run it myself, and it's been live with paying subscribers since August 2026. It has separate revision spaces for the NIE, NPPF Sergeants and NPPF Inspectors, all under one account, and it works in a browser on a phone or a laptop, so there's nothing to install. Officers who prefer an app can also use the iPhone and iPad app in the UK App Store, signing in with the same account.
Inside are 143 topics, 1,738 cards (286 of them written scenarios) and 2,594 practice questions, and every question explains why the right answer is right and why each wrong option is wrong. The app has short spaced-review sessions of 15 items and full-length mocks, and a readiness estimate that's labelled as an estimate rather than a prediction. Four complete NIE topics are free to try with no account at policelawprep.co.uk/free.
The process
How it works for a force
You email me how many officers, and which sitting they're aiming for.
I send a quote, your procurement team raises a purchase order against it, and I've got the supplier paperwork ready (company details, a bank-details letter on headed paper, insurance certificates and data-protection answers).
I send one link to the training team. Each officer opens it, signs up with any email address, and has full access to all three exam workspaces until 14 days after the sitting. There's no card to enter, no app-store purchase and no expenses claim to file. An officer who uses the iPhone app signs in with the same account and buys nothing in the app.
You get one invoice from A Large Company Ltd quoting the purchase order number, on 30-day terms, paid by bank transfer, and there's no VAT on it.
After the sitting I send the training team the number of seats that were activated. No individual officer's study data goes to the force.
Pricing
What it costs
£75 per officer, per sitting
That covers full access from the day the link goes out until 14 days after the sitting, up to five months, which is the public price of £15 a month over a five-month window. The seat price is the same whenever the link goes out, and there's no minimum number of officers. Twenty officers would be £1,500 on one invoice.
If the team would rather have year-round access, it's £150 per officer per year instead.
A seat that nobody claims moves to your force's next sitting within 12 months, so a seat paid for an officer who drops out before signing up isn't lost. An officer who already pays for their own subscription can cancel it and use a force seat. A force purchase runs on a short licence agreement that comes with the quote, rather than the consumer terms on the site.
Content
How the questions are sourced
Police Law Prep is independent and isn't affiliated with or endorsed by the College of Policing, any police force or any publisher. The content is written from primary public sources, which are legislation.gov.uk, the PACE Codes of Practice on GOV.UK, CPS charging guidance and Sentencing Council guidelines, used under the Open Government Licence, plus leading cases described in its own words, all credited on the content sources and licences page. It doesn't reproduce the current official manual, and it's meant as a study companion to be used alongside the manual, not a replacement for it.
Nearly every NIE card (514 of 518) names the section, code or case it relies on, every answer explains why it's right and why the other options aren't, and the sergeants' and inspectors' topics each carry a source log. The NIE bank has been checked line by line against the law this autumn. The sergeants' and inspectors' banks are live and in use, but the same check on them is more recent and its corrections are still in review, so for anyone studying for promotion they're at an earlier stage of verification than the NIE material. A monthly automated check watches 22 core legislation and guidance pages, and anything it flags gets reviewed against the source before the affected items are corrected. If your trainers spot anything that doesn't match how the exam tests the material, I'll correct it from the source, usually within a few days.
Data
What data it holds on each officer
For each officer the app stores an email address, a sign-in, their study progress and notes, and any optional answers they choose to give. It never sees card details. Account and entitlement data sits in a database in London (Supabase), the site and study-progress sync run on Vercel in the United States, and email goes through Resend, also in the United States, and the safeguards for those transfers are set out in the privacy notice. A Large Company Ltd is the controller of each officer's account, the force gets only the seat count, and an officer can delete their account from inside the app, which completes within seven days.
Evaluation
Trying it before a purchase order
A training team can ask for an evaluation link for up to three people, with 14 days of full access each and no card needed, so you can use the whole product before deciding anything. After that I can send a quote for whatever number of officers you have in mind.
Contact
Asking for a quote or an evaluation link
Email hello@policelawprep.co.uk and say how many officers and which sitting, or book 30 minutes with me.
If you're paying for Police Law Prep yourself, send this page to whoever runs training in your force. If the force buys seats, you can cancel your own subscription and use a force seat instead.
