Every post covered. Every licence in view.
Klacks staffs sites and patrols with no gaps — automatically keeping track of SIA licensing and Working Time Regulations night-work rules. Installed on your premises, so your deployment and client data are stored on your own servers — optionally with a locally hosted AI model.
Note on the sample data: All names, places (for example Winterthur), addresses and figures in these recordings are fictitious demo data with a Swiss background, written in Latin script. They only illustrate the product – you do not need to know or be able to read them. In your own installation you enter your own data, and the interface is multilingual.
SIA licensing, night work and many sites
Keeping SIA licensing requirements under control
The Private Security Industry Act 2001 and SIA regulation require a valid licence for most roles — tedious to check by hand across many staff and sites.
Identifying night workers & health assessments
Anyone who regularly works at least 3 hours between 11pm and 6am counts as a "night worker" under the Working Time Regulations and is entitled to a free health assessment — easy to miss with rotating patrols.
Many sites, one plan
Every site has its own posts, hours and requirements — keeping track of it all by hand is barely feasible.
Your finished shift plan in three steps
Install
Klacks is installed on your own infrastructure — via Docker; allow about half an hour for the first start.
Adjust rules
Public holidays and rest periods come preconfigured for your country, surcharges where defined for your country — and you can adjust them anytime.
Plan automatically
Klacks builds shift plans, flags conflicts and optimizes routes — with an AI assistant if you want.
How Klacks takes the load off security providers in the UK
From covered posts to valid SIA licences — everything works together.
Sites & posts with no gaps
Every post across every site — Klacks shows every open slot immediately and fills it automatically on request.
SIA licence matched automatically, expiry in view
Klacks only assigns shifts to staff with the matching SIA licence qualification — and warns before a licence on file expires. If a required licence is missing or has expired, Klacks refuses the assignment, in manual planning too.
Night shifts counted automatically
Klacks automatically counts night shifts per employee and warns as soon as the configured threshold for regular night work under the Working Time Regulations is reached — the basis for triggering the statutory health assessment in good time.
Patrols optimised
For mobile patrol services, Klacks plans routes so journeys stay short and intervals are met.
Installed on your premises: data on your servers
Klacks runs on your own infrastructure — deployment and client data are stored on your servers — and with a locally hosted AI model, no AI request goes to an external AI provider.
Klacksy understands your request
"Cover the night shift at the North site" is all it takes — Klacksy starts the planning, Klacks checks SIA licensing, availability and night-worker status.
What Klacks can do — in real recordings
Short videos from the running app, sorted by topic. Choose a chapter; only the video of the open chapter ever plays.
Note on the sample data: All names, places (for example Winterthur), addresses and figures in these recordings are fictitious demo data with a Swiss background, written in Latin script.

- Klacksy helps you get it right in every one of these cases: describe your rule in the chat in your own words, for example “Sundays earn a 50% surcharge.” — Klacksy asks follow-up questions, shows a preview and only saves once you confirm.
- Klacksy also creates scenarios and starts planning inside them — tell it in the chat, for example: “Plan Winterthur from November 2 to 8.”
- Klacksy, the built-in AI assistant, can also do all of this for you on request — for example, tell it in the chat: “Add expenses of 24.50 for Mia on October 6.”
A calendar for every nation
Bank holidays are anything but uniform across the United Kingdom: England & Wales, Scotland and Northern Ireland each observe their own set of statutory holidays, and individual councils add local holidays on top — such as Glasgow Fair Monday, the third Monday in July. Klacks handles exactly what simple tools get wrong.
- Three nations, three sets of holidays2 January and St Andrew's Day (30 November) are bank holidays only in Scotland; St Patrick's Day (17 March) and the Battle of the Boyne — known as "the Twelfth" (12 July) — only in Northern Ireland: pre-configured and ready to use.
- Mix calendarsA care, security or logistics business with sites in London, Edinburgh and Belfast runs all three calendars side by side — including bank holiday premiums and the reduced staff availability on days when nurseries and schools close in only one nation.
- Binding or purely informationalFor each calendar, you decide whether a bank holiday affects hours & premiums — or simply appears as a reminder.
It all comes down to the settings
Klacks offers countless ways to calculate rules and hour credits for nights, weekends, public holidays and overtime — exactly the way your contracts and company agreements require.
- Nights and weekends You set the night window and the surcharge rates yourself, and choose up to three weekend days — as a multiplier that is added to the hours worked as a time credit in hours.
- Public holidays and overtime A separate public-holiday rate, and overtime per day or per week in up to three tiers. When several surcharges fall on the same hour, the highest one applies — or all of them add up.
- Your own calculation with a macro If that is not enough, a macro does the maths: a short script using weekday, time of day, public holidays and contract values — with conditions, loops and functions of your own.
- Scheduling rules Rest periods, maximum daily and weekly hours, consecutive working days, free Sundays or hour caps per period — each one as a warning or, in automatic planning, as a block.
Rule violations: Klacks warns you instantly
Klacks flags time collisions, rest periods that are too short, too many consecutive working days and work on holidays right as you plan — as an error or warning in the error list.

The best route — automatically
From your service addresses, Klacks works out the most sensible order and shows the finished route on the map. All you choose is the mode of transport.
- 1Capture addresses Every service location has an address on file — Klacks knows the way.
- 2Optimize the order Klacks works out the shortest sensible sequence — detours and empty runs are reduced.
- 3Show it on the map The finished route appears on the map — by car, bike, or on foot.
Stylized example: Klacks connects the service locations into the shortest route.
Night shift, licence, one plan
Klacks automatically counts night shifts and warns once the configured threshold for regular night work is reached, assigns shifts only to staff with the matching SIA licence qualification, and so provides the basis for the health assessment that falls due — no manual recalculating required.
