SIA Mock Test UK is an independent study resource. It is not affiliated with, endorsed by or approved by the Security Industry Authority, GOV.UK or any awarding organisation. Practice questions are original and are not live exam questions. This service does not replace mandatory licence-linked training, practical assessment or first-aid requirements. Always confirm current requirements with GOV.UK, your approved training provider and your awarding organisation.

Sit a full mock under the clock

A timed run through the units for your route, marked the moment you hand it in, with a breakdown of which learning outcomes let you down.

The SIA will not accept qualifications granted by BIIAB on or after 11 August 2026. Qualifications granted before that date are still accepted.

This applies to the door supervisor, security guard and public space surveillance (CCTV) licences. If you are booking training now, check which awarding organisation your provider uses before you pay.

Security Industry Authority, Check what training you need to get an SIA licence. Checked 12 September 2026.

How it works

Three steps, and the first one is free

1

Choose your route

Door Supervisor, Security Guard or CCTV Operator. Tell us which nation you are studying in, because some of the law differs.

2

Sit a mock test

Timed, with the clock held by the server rather than your browser. Your answers are saved as you go, so a lost connection is not a lost attempt. No account needed for your first one.

3

See where you are weak

Results break down by unit and learning outcome, so you know which part of the specification to go back to rather than just a score.

Before you start

Read what you are assessed on

The SIA publishes a specification for every licence-linked qualification, listing unit by unit what you must know. They are free, and our questions cite them.

What a mock here can and cannot tell you

The written units are the part an online mock can genuinely prepare you for. The rest is done in person.

An online mock cannot assess or replace mandatory practical training, physical intervention assessment or first-aid requirements. Those are completed in person with an approved training provider.
