HR AI and automation, built around your HR system

Some AI in HR now comes inside the HR system: Ciphr and Access PeopleHR have assistants, and HiBob summarises performance reviews. The slow work tends to sit between systems: right to work evidence, payroll changes, fit notes, disciplinary files and subject access requests. HR AI, as we build it, does that work around your HR system, and a named person in HR decides.

This page is for in-house HR teams in businesses of about 50 to 1,000 staff, and for HR consultancies with several clients. At the start of 2025 the UK private sector had 38,435 businesses of 50 to 249 employees and 8,335 of 250 or more.

Where the time goes

  • New starters

    Right to work is checked before day one: a Home Office online check from a share code, a registered digital provider for British and Irish passports, or a manual document check, with a dated copy kept for the employment plus two years. The principal written statement is due on the first day.

  • Sickness and absence

    Since 6 April 2026, Statutory Sick Pay has no waiting period or lower earnings limit: £123.25 a week or 80% of normal weekly earnings, if lower. A fit note is due after more than seven days off in a row. The ICO advises keeping illness details apart from the absence record.

  • Disciplinaries and grievances

    The Acas Code asks for investigation and a meeting without unreasonable delay, written notice with copies of evidence, a companion, a written decision and an impartial appeal. For acts from 1 October 2026, most tribunal claims have a six-month limit, not three.

  • Subject access requests

    A worker can ask verbally or in writing, and the ICO says a grievance or tribunal claim is no reason to refuse. The answer is due within a month, after reasonable searches of mailboxes and files, with other people's details redacted where needed.

The systems you already run

  • Personio and HiBob

    Personio's API v2 uses OAuth 2.0 and covers people, employments, absences, attendances and documents, with signed webhooks. HiBob documents APIs for employee data, time off, attendance, documents and tasks, with webhooks.

  • Breathe and BrightHR

    Breathe documents an API that takes a key in an X-API-KEY header. BrightHR's developer portal covers employees, Blip clock-ins and breaks, and approved absences.

  • Access PeopleHR and Ciphr

    Access PeopleHR publishes Swagger API documentation, keys that can exclude basic salary, and a new-starter webhook. For Ciphr we found no public API documentation, so we would ask Ciphr first.

  • Payroll

    Xero's Payroll UK API uses OAuth 2.0 and covers employees, leave, statutory sick leave, timesheets, pay runs and payslips. Where payroll takes a file instead, we produce it and keep a copy.

What we would build

  • Starter to payroll in one flow

    From signed offer to first payslip: the right to work check by the right route, its copy filed with a deletion date two years after leaving, follow-up checks diarised, the principal statement issued on day one, and the starter written once to the HR system and payroll.

  • Absence that reaches payroll

    Sickness logged once and sent to payroll with SSP from the first day. Fit notes are read, dated and filed apart from the absence record, open only to those who need them. Return-to-work meetings go to the line manager as tasks.

  • A file for every case

    Each disciplinary or grievance moves through the Acas Code steps with dates, from investigation to appeal, with notes and letters in one restricted file. If you run Ciphr, its case management may already do this, and we would build around it.

  • A subject access desk

    Logs each request and runs its clock, paused while you wait for clarification. It searches the HR system, case files and mailboxes, queues documents for redaction review, and acknowledges data protection complaints within 30 days.

Where AI helps

AI should not decide a warning, a dismissal or a pay change. Under UK GDPR Articles 22A to 22D, a significant decision without meaningful human involvement needs safeguards, and health data restricts it further. The ICO expects reviewers who can overrule the tool; Acas advises checking output for bias.

  • Reading fit notes into dates and the clinician's comments, with an HR adviser confirming each one before it reaches payroll.
  • Drafting invitation and outcome letters from the case notes and your policy, with the HR manager editing and signing each one.
  • Finding a requester's data across mailboxes and files and proposing redactions of other people's details, with your data protection lead checking every page.

How we would start

We would start with one process, usually starters or sickness. With the people who run it, we would map it from first email to payslip, list the records each rule asks for, and connect your HR system's API first. The first working version would check each new case, write it once to the HR system and payroll, and show HR what needs a decision.

That first stage, the design and a written scope, typically takes one to three weeks. Like every stage, its price is fixed and agreed before it starts, and you can stop after it. How a project runs

Rules we build around

The software keeps the records these ask for. The duties stay with you.

  • Immigration, Asylum and Nationality Act 2006

    A prescribed check before employment starts gives a statutory excuse, kept by follow-up checks where permission is time-limited. Copies are kept for the employment plus two years, then destroyed. Using a digital provider leaves the duty with the employer. The civil penalty is up to £60,000 per illegal worker.

  • UK GDPR Articles 22A to 22D

    They replaced Article 22 on 5 February 2026, under the Data (Use and Access) Act 2025. A significant decision, such as a dismissal or pay change, taken with no meaningful human involvement needs safeguards: information, representations, human intervention and a way to contest it. Health data restricts it further.

  • Data (Use and Access) Act 2025: access requests and complaints

    Since 5 February 2026, the month to answer a subject access request pauses while you wait for clarification you reasonably need, and complex or numerous requests allow two more months, by notice within the first month. Searches must be reasonable and proportionate. From 19 June 2026, data protection complaints must be acknowledged within 30 days.

  • Acas Code of Practice on disciplinary and grievance procedures

    Tribunals take it into account and can adjust an award by up to 25% for unreasonable failure to follow it (Trade Union and Labour Relations (Consolidation) Act 1992, section 207A). Acas consulted on an updated Code until 23 September 2026 and expects it in 2027.

  • Employment Rights Act 2025

    Day-one paternity and unpaid parental leave from 6 April 2026; six-month limits for most tribunal claims about acts from 1 October 2026; all reasonable steps to prevent sexual harassment from 30 October 2026; a six-month qualifying period for unfair dismissal, for dismissals from 1 January 2027.

Questions

Will you replace our HR system?

Usually not: we build around it. Personio, HiBob, Breathe, BrightHR and Access PeopleHR document their APIs, and Workday publishes API references, so we work through them, with access your administrator grants.

Our HR system already has an AI assistant. Do we need more?

Often not. Ciphr's assistant answers questions from live HR data, and Access PeopleHR's Copilot helps draft responses on performance and disciplinary issues. If that covers the job, use it. We build HR automation for work that crosses systems: payroll, mailboxes, case files and subject access.

Can AI flag absence or performance problems?

It can flag them for a person to review. A dismissal or pay change based solely on automated processing is a significant decision, and sickness records are health data. The ICO's example has an HR manager checking tracking data and talking to the worker before a warning: that is the pattern we build.

We are an HR consultancy. Can one system serve every client?

Yes, with each client's data kept apart. Where you process staff data for a client, Article 28 of the UK GDPR requires a contract covering instructions, confidentiality, security, sub-processors and deletion or return at the end. We record each client's terms, policies and letters separately.
