Plainfiles is run by TurboKast Ltd (company number SC881077), 29 Commercial Street, Dundee, DD1 3DG. The licences are for UK training centres.
The two licences
| Licence | Question banks covered | Price |
|---|---|---|
| SIA site licence | SIA door supervisor, SIA security officer and SIA CCTV operator (England and Wales law) | £99 |
| Personal licence site licence | SCPLH (Scottish Certificate for Personal Licence Holders, Scotland) and APLH (Award for Personal Licence Holders, England and Wales) | £49 |
- A centre that teaches both pays £99 plus £49. We quote the two licences separately.
- A centre that only teaches the SCPLH still pays £49. The APLH bank comes with it.
- 12 months from the day you pay, for your centre’s own learners and trainers.
- Pay by card or by invoice. UK buyers only, for now.
Read the one-page licence (PDF). It is short and in plain English, so your manager can read it before you decide.
What you get
For each bank in your licence: a PDF of the questions, a PDF of the answers and notes, and a self-marking quiz that opens in a web browser. Every question has an answer, an explanation and the law or guidance it relies on. You get the licence and all the files in one download after you pay. You can look inside first with the free 25-question practice tests: SIA door supervisor, SIA security officer, SIA CCTV operator, SCPLH and APLH.
Try it free for 14 days first
We can give you a private link to the PDFs and the self-marking quiz for 14 days. You do not give us any payment details. Email us and say which course you teach.
Buy a licence
Card checkout is by Stripe: it asks you to confirm that you are in the UK and agree to the terms of sale. Prefer an invoice, or a card payment link sent to you? Email us the licence you want and the centre’s legal name, and we send you an invoice or a card payment link.
What the banks are, and what they are not
- The questions are original. They are not the real exam, and passing them does not guarantee a pass.
- They are not issued, endorsed or checked by the Security Industry Authority (SIA) or any awarding body.
- The SIA banks cover the law of England and Wales only.
- The banks are drafted with AI tools, and every rule is checked against the source.
- They are not legal advice. The law changes, so check the sources before you rely on an answer.
- The licence covers the banks as published. It does not include custom questions or changes for your course.
Questions
Who counts as our own learners and trainers?
The licence says: the people on your courses and the people who teach them. It does not cover other centres, and your files may not be put on a public website or shared folder.
What happens after 12 months?
The licence ends. It does not renew by itself. If you want to carry on, you buy a new licence.
What if something is wrong with a file?
Our terms of use say how we fix, replace or refund a faulty file.
