The Working Time Regulations 1998 require a written, freely revocable opt-out for the 48-hour week, which employers must be able to evidence. With high staff turnover and expensive bank and agency shifts, that record-keeping is the real pain point — Klacks is deliberately built for the private sector, not the NHS.
Every 48-hour-week opt-out needs to be in writing and evidenced — with high staff turnover, that's a growing administrative burden.
Short-notice cover through agency staff or internal bank pools is often the costliest option — better forward planning reduces how often you need it.
Private care homes, security providers and FM teams all deal with staff turnover that makes manual rotas go stale fast.
Klacks was built for sectors with strict security and compliance requirements, where sensitive staff data should never leave your own infrastructure. As an open-source solution, Klacks can run entirely in your own data centre or on secured local servers — without depending on US cloud providers. That makes UK GDPR and ICO compliance entirely your own responsibility to manage, not a vendor's.
On-premise sovereignty: full control over rosters, opt-out records and logs within your own IT environment.
Open LLM architecture: AI-assisted scheduling suggestions can also run on locally hosted language models, so no data ever leaves for external APIs.
Auditable source code: a fully inspectable codebase for IT audits and internal compliance reviews.
Deliberately built for the private sector — no NHS ESR integration, so you're up and running fast.
If a staff member calls in sick, Klacks instantly finds the best-qualified internal replacement — before an expensive bank or agency shift becomes necessary.
Klacks tracks each employee's opt-out status and average weekly hours continuously — on file whenever HR needs to check.
Finished hours, overtime and allowances export directly in a format ready for BrightPay, widely used across the UK and Ireland.
The GA-powered autofill assistant plans shift rotations while respecting the working-time limits on file.
Only staff with a matching qualification and a valid security or care licence are ever suggested for a shift.
Klacksy isn't a bolted-on marketing chatbot — it's embedded directly in the Klacks interface. Staff and schedulers ask about shifts via chat, request shift swaps, or resolve qualification conflicts within the team. A built-in skills and rules system ensures Klacksy only ever suggests changes that actually match the qualifications and working-time limits of the people involved.
