Every site planned to a shine.
Klacks assigns sites and cleaning teams efficiently — with a clean documentation basis for TUPE transfers when providers change.
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.
The National Living Wage, TUPE and many sites
Keeping the National Living Wage in sync
Since 1 April 2026, the National Living Wage has been £12.71 an hour — up from £12.21 since April 2025. Payroll has to apply these rates consistently across every site.
TUPE transfers when providers change
When a cleaning contract changes provider (a service provision change), the transferring cleaners' terms and conditions — including contractual working hours and rotas — pass automatically to the new employer. TUPE 2006 requires a seamless transfer.
Many sites, changing teams
Every site has its own hours and requirements, and teams change frequently — 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 cleaning services in the UK
From optimised routes to traceable TUPE documentation — everything works together.
Site routes optimised
Klacks sequences sites so that journeys stay short — by car, bike or on foot.
Hours for payroll
Klacks records the hours worked at each site and provides them as a file export for your payroll — you apply the National Living Wage of £12.71 an hour in your payroll software.
TUPE transfers cleanly documented
You record transferring cleaners in Klacks along with their existing rotas and terms and conditions — the basis for documenting TUPE transfers in a traceable way.
Teams scheduled flexibly
Changing rosters, casual staff and holiday: Klacks keeps track of it all and suggests suitable assignments.
Qualifications matched
Specialist cleaning, machinery, secure areas: only appropriately qualified staff are ever scheduled.
Klacksy understands your request
"Schedule the city-centre sites for tomorrow morning" is all it takes — Klacksy starts the planning, Klacks optimises the route and team allocation.
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.

- 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.
