How to build a comprehensive onboarding process for UK employees
Jump Links placeholder, DO NOT REMOVE
- Onboarding is the structured process that turns an accepted offer into a confident, productive employee – induction is one part of it, not the whole thing.
- The onboarding processes that work start before day one and keep running through the first 90 days, with check-ins and feedback built in throughout.
- From 6 April 2026, Paternity Leave, Unpaid Parental Leave and Bereaved Partner’s Paternity Leave no longer require a qualifying period, so onboarding materials and handbooks need updating now.
A new hire accepts the offer, turns up on day one and by the end of the first week has gone quiet – unsure what’s expected of them, unsure who to ask and quietly wondering whether they made the right call. Onboarding that stops at a welcome email and a laptop produces exactly this outcome.
Onboarding is the structured process for welcoming a new employee: completing the necessary administration, and helping them understand the organisation they’ve joined, the people they’ll work with, the role they’re there to do and what good looks like in it. In the UK, the same activity often goes by another name: ACAS uses “induction” for much of this work. The distinction worth keeping is that onboarding is the employee’s full transition into the organisation, often running for months, while induction – the welcome session, the policy briefing, the early training – is part of that transition, not the whole of it (CIPD).
This guide sets out onboarding best practices for that transition: before the first day, day one itself, the first week, a 30-, 60- and 90-day plan, the UK employment requirements involved and how to adapt the process for remote and hybrid employees.
What should an effective onboarding process achieve?
A useful way to think about onboarding is in terms of four things a new employee needs to understand before they can do their job well: the organisation they’ve joined, the people they’ll work with, what their role requires and how they can become effective in it. Most programmes handle the first two easily enough; the other two need ongoing manager attention, which is where onboarding usually falls short.
By the end of onboarding, an employee should know what’s expected of them, how their performance will be assessed, where to find information day to day, who to approach when something isn’t working and how their work contributes to the team’s wider objectives. If a new hire can’t answer those five questions after a month, the process has a gap, whatever the completion checklist says.
Onboarding has an employer-side set of outcomes too: HR and the hiring manager should be confident that required documentation is complete, relevant policies have been communicated, systems and equipment provided, training delivered and early performance expectations documented and agreed, not just discussed in passing.
Step 1: Start onboarding before the employee’s first day
Preboarding is the period between an employee accepting an offer and their first day, and it’s easy to treat as dead time. It isn’t: organisations should use it to clear practical barriers that would otherwise eat into the first week, and to protect the positive experience recruitment worked hard to build.
Right to work is the non-negotiable item. Employers must carry out the appropriate right-to-work check before someone starts working, following the checking routes and record-keeping in current Home Office guidance – manual document checks, the Home Office online service or an Identity Service Provider for digital checks, each with its own record requirements.
For remote and hybrid employees, preboarding needs to answer three questions before day one: where equipment will be delivered, how systems will be accessed and when the new starter will first meet their manager and team. ACAS’s induction checklist specifically flags checking that homeworkers have the equipment, IT access and a safe workspace they need.
This matters beyond administration. A candidate who has been through a well-run, responsive recruitment process and then hears nothing for three weeks experiences that gap as a step backwards. Preboarding is where the continuity between candidate and employee either holds or breaks.
Step 2: Get the first day right
The first day has a fixed set of practical jobs worth turning into an employee onboarding checklist: a welcome from the manager, workplace or remote setup, access to systems and equipment, introductions to the immediate team, health and safety information, an explanation of working arrangements and an overview of the onboarding schedule from here. None of this is complicated, but it needs planning rather than improvisation – a new starter notices immediately when it hasn’t been.
Payroll administration also starts on day one. Employers must report a new employee to HMRC on or before their first payday, using the relevant employee details or P45 information to set the correct tax code. Getting this wrong shows up in the new starter’s first payslip – a poor place for a process failure to surface.
Employees should also receive their written statement of employment particulars on day one; it’s a legal requirement from the outset, not something to catch up on in week two.
The day should end with a manager check-in: a short conversation to answer questions, confirm access issues are actually resolved and set expectations for the rest of the week. ACAS’s induction checklist is a useful reference for the full list of first-day tasks.
Step 3: Build role clarity during the first week
Once the organisation-wide orientation is done, the first week should shift focus to the role itself. By the end of it, a new employee should have a clear sense of what they’re responsible for, how they’re expected to work and what good performance looks like in practice.
That clarity rarely comes from the job description alone. Managers need to walk new hires through their responsibilities, priorities, objectives and the KPIs that matter for the role, rather than assuming these are self-evident.
It’s also the point to map how the role connects to everyone else: identify key stakeholders, decision-makers and regular collaborators, and explain when and why those interactions happen. A new starter who understands the shape of their working relationships in week one avoids a lot of trial and error later.
Regular manager check-ins should be a standing feature of this week, not a one-off, so new hires can keep raising questions and training needs. Larger or multi-department employers should build a standard core onboarding framework, with individual departments layering role-specific training on top – consistent at the base, without forcing every team into an identical script.
Step 4: Create a 30-, 60- and 90-day onboarding plan
A new employee can complete every item on the first-week checklist and still be months from fully onboarded. Systems, relationships, responsibilities and the unwritten parts of how an organisation works all take longer to absorb than the admin does, which is why onboarding needs a plan running to 90 days, not seven.
First 30 days
The early focus should be understanding rather than output: the role, systems, key processes, relevant stakeholders and the organisation more broadly. Set initial training goals, and build in time to shadow colleagues or observe workflows the new hire will eventually own. Manager check-ins should be frequent, specifically to surface gaps in equipment, access, information or training before they become blockers. Agree initial objectives so the employee has a concrete sense of early progress, and review how they’re settling into the team alongside how they’re progressing on tasks – the two aren’t the same, and tracking only the second misses problems that show up as disengagement rather than missed deadlines.
Days 31–60
This is where the employee should move from learning the role to independently owning it. Review progress against the objectives agreed in the first 30 days, and give specific feedback on what’s working and where more development is needed – generic reassurance doesn’t help here. It’s also typically when training or knowledge gaps that weren’t visible earlier start to surface, once the new hire is doing more of the work unsupervised.
Days 61–90
By this point, review whether the employee is consistently performing their core responsibilities and understands what’s expected of them beyond onboarding itself. Discuss progress against objectives, remaining development areas and goals for the months ahead. This is also the right moment to ask the new hire for feedback on their own onboarding experience while it’s still recent: what information was missing, which tasks felt unnecessary and where they felt unsupported. Feeding that back is what actually improves onboarding for the next cohort, rather than repeating whatever was done last time.
UK employment requirements during onboarding
Rather than covering UK employment law in full, here are the principal areas to build into an onboarding process: right-to-work checks before employment begins; day-one written employment particulars; HMRC and payroll administration; workplace pension enrolment where applicable; health and safety information and training; DBS or role-specific checks where required; and clear information on leave, sickness and workplace policies.
That list has just changed. The Employment Rights Act 2025 moved several family leave entitlements to day-one rights from 6 April 2026: Paternity Leave and Unpaid Parental Leave no longer require a minimum period of service, and Bereaved Partner’s Paternity Leave – already available without a qualifying period under the Paternity Leave (Bereavement) Act 2024 – is extended further from the same date. Employee handbooks, onboarding materials and HR systems built around the old service requirements need checking, because a new starter in their first week can now be entitled to leave that used to require months of tenure (see the April 2026 Employer Bulletin).
None of this is a substitute for legal advice. GOV.UK and ACAS are the right places to confirm what currently applies, and right-to-work requirements specifically are set out in Home Office guidance.
Adapt the onboarding process for remote and hybrid employees
Remote employees need the same onboarding outcomes as anyone else, but usually need different methods to get there. Moving every office induction session onto a video call ticks the same boxes, but it misses the informal learning that happens when people are physically near each other – overhearing context, asking a quick question, picking up how things actually get done.
Hardware, software, logins and security access need to be sorted before the employee needs them, not arranged reactively once they hit a wall. A remote employee can’t lean over to the next desk to get a login fixed.
Introductions need to be deliberate rather than assumed: schedule meetings with the manager, the team and key stakeholders rather than relying on relationships forming on their own. Managers should also use check-ins to monitor how well a remote employee is integrating, not only what they’re producing, since isolation is harder to spot when the only visible output is the work itself.
How to measure and improve your onboarding process
A 100% checklist completion rate tells you the admin got done. It doesn’t tell you whether the employee understands what’s expected of them or feels part of the team – measuring only the first gives a false sense of how onboarding is working.
Collect new-hire feedback at several points – after the first week, and again around 30, 60 and 90 days – to see where the experience holds up and where it deteriorates as the formal structure falls away. Alongside that, track operational measures: completion of essential tasks, time to system access and mandatory training completion.
Where possible, connect onboarding to longer-term outcomes: time to productivity, probation outcomes and early turnover. These should inform the picture rather than prove it, since onboarding is rarely the sole cause of a change in any of them.
Segmenting results by team, location or manager, where sample size allows, often improves onboarding faster than any organisation-wide change. If one department consistently reports poor role clarity or delayed access, that points to a local implementation problem, not a flaw in the framework. Greenhouse’s reporting and insights tools can help surface these patterns across teams.
Build a more connected onboarding process with Greenhouse
The handoff from hiring to onboarding is where good recruiting work quietly unravels – candidate information gets re-entered by hand, start dates slip because preboarding tasks stall and new hires experience the gap between offer accepted and day one as exactly the kind of silence this guide opened with.
Greenhouse Onboarding is built to close that gap: consistent onboarding plans instead of one reinvented per hire, automated admin that otherwise falls through the cracks, coordinated stakeholders who all need to act before day one and the information new hires need as they join.
If preboarding, day one and the first 90 days are currently held together by spreadsheets and good intentions, explore Greenhouse Onboarding.
FAQs
What is an employee onboarding process?
An employee onboarding process is the structured set of activities that take a new hire from accepting an offer to being a fully contributing member of the team. It covers preboarding, the first day, early role-specific training and ongoing support typically through the first 90 days, and includes both practical administration, such as right-to-work checks, payroll and system access, and the less tangible work of helping someone understand their role, their team and the wider organisation.
What is the difference between onboarding and induction?
In the UK, the terms are often used interchangeably, but ACAS treats induction as the activities, such as welcome sessions, policy briefings and initial training, that form part of the broader onboarding process. Onboarding is better understood as the employee’s full transition into the organisation, which can run for several months, while induction refers to the specific sessions that happen early in that transition.
How long should an onboarding process last?
Most effective onboarding processes run for at least 90 days, structured around clear milestones at 30, 60 and 90 days. The first weeks focus on orientation and administration, while the following months shift towards independent ownership of responsibilities and longer-term integration into the team.
What are the legal requirements for new employee onboarding in the UK?
UK employers need to complete right-to-work checks before employment starts, provide a written statement of employment particulars on day one, report the new employee to HMRC for payroll purposes, enrol eligible employees into a workplace pension and provide required health and safety information. From 6 April 2026, Paternity Leave and Unpaid Parental Leave also became day-one rights under the Employment Rights Act 2025, so onboarding materials should reflect this change. Current GOV.UK and ACAS guidance should always be checked, since requirements can change.
How do you onboard remote or hybrid employees effectively?
Remote onboarding needs to achieve the same outcomes as in-person onboarding but usually requires more deliberate planning. That means arranging hardware, software and system access before the employee’s first day, scheduling introductions to the manager and team rather than leaving them to happen informally and having managers actively check in on how well the employee is integrating with the team, not just what they’re producing.
