HR onboarding in the UK: Everything you need to know

An effective onboarding process helps new hires build relationships, understand their role, and develop confidence from their first day. And it’s important to get the process right, as a new employee’s onboarding experience can have a major influence on how they perceive the company, how productive they are, and how long they stay. 

For HR teams, creating a smooth onboarding journey means managing multiple steps and systems and bringing together stakeholders. When these processes are well connected, organisations can reduce unnecessary admin and spend more time focusing on strategic people initiatives.

However, maintaining a consistent onboarding experience can be challenging. Rippling’s latest State of the Back Office Leader report found that 31.7% of HR teams consider onboarding tasks a significant time commitment, while employee information updates (50.4%) and employee questions (43.6%) also take up valuable time. 

Plus, research from employee experience platform Cognexo found that over half (54%) of office-based employees were dissatisfied with their onboarding experience.

But with the right approach and the right software, you can make the onboarding process easier, more efficient, and more engaging.

This guide explores the essential steps for onboarding employees in the UK, from preboarding and workplace preparation to building an effective first 90-day plan. We’ll also look at how integrated HR software like Rippling can automate repetitive tasks and connect your systems, helping HR teams create a better onboarding experience in less time.

Key takeaways

• Onboarding involves coordinating legal requirements, payroll processes, HR administration, and IT setup across multiple systems, teams, and stakeholders to create a smooth experience for new hires.

• Manual onboarding processes can lead to delays, duplicated work, and increased administrative effort, particularly when managing compliance checks, employee data, equipment, and access to workplace tools.

• Automation platforms like Rippling help simplify onboarding by connecting HR, payroll, and IT workflows, improving speed, consistency, and compliance while reducing repetitive manual tasks.

The preboarding process: Documents, access, setup

A strong preboarding process ensures that a new hire has everything they need to begin their role with confidence and that your organisation is compliant with UK employment regulations. It also helps you reduce administrative delays, create a smoother first-day experience, and ensure HR, IT, and managers are aligned before the employee arrives.

Remember, different types of employees may require different onboarding processes. For instance, if you employ remote or hybrid employees, their health and safety briefings should relate to their specific work environments. You may need to walk contractors through your invoicing process, while shift workers might need onboarding with rostering and time tracking systems. 

However, the information below is relevant to all new hires.

Verify work eligibility and compliance

UK employers must complete a right to work check before a new hire begins to confirm that the individual is legally allowed to work in the UK. This check helps you avoid potential penalties for employing someone without the correct permission to work.

If your new employee is not a UK or Irish citizen, they may need a visa or other immigration status that allows them to work in the UK. You'll need to verify this through the appropriate Home Office processes and ensure any restrictions, such as limits on the type of work or hours they can complete, are followed.

Employers must also make sure their onboarding process aligns with UK employment law, including providing a written statement of employment particulars setting out key terms and conditions. This includes information such as pay, working hours, holiday entitlement, workplace policies and notice periods, as required under the Employment Rights Act.

If appropriate, you may also choose to carry out a background check. However, checks should be proportionate to the role, carried out fairly and completed with the candidate’s full knowledge and informed consent. Learn more in our guide to employment background checks in the UK.

You'll also need to determine if the individual must go through a DBS check (Disclosure and Barring Service check, formerly known as a CRB check). DBS checks are necessary for employees who will be working with vulnerable individuals or in positions where they’ll be responsible for security.

You then provide the employee with their employment contract no later than their first day (the offer letter should have gone out at offer stage). Download our offer letter checklist to help craft a clear and compliant employment contract that sets the right expectations from the start.

Key onboarding compliance tasks

Set up payroll, tax, and pension

UK employers must add each new employee to payroll and report their details to HM Revenue & Customs (HMRC) under the PAYE (pay-as-you-earn) scheme. In this system, you deduct income tax and National Insurance contributions from the employee's wages before paying them and then report this information to HMRC.

You must also assess whether new hires are eligible for automatic enrolment into a workplace pension scheme. Under UK pension regulations, eligible employees must be enrolled and receive employer pension contributions, although they can choose to opt out after being enrolled.

Other statutory benefits in the UK include sick pay; maternity, paternity, and other family-related pay; and National Insurance contributions, which go towards an individual's State Pension. You can find more information in our guide to UK statutory and supplemental benefits.

As part of the onboarding process, you'll need some information from your new hire. This will include a P45 from their previous employer or, if they don’t have one, a completed HMRC starter checklist so you can determine the correct tax code and deductions. They must also provide their National Insurance number and their student loan deduction status, if applicable. AI-powered onboarding software can automatically identify missing payroll information, flag incomplete forms, and trigger payroll setup once employee records are complete.

Prepare equipment and system access

Whether they’re working onsite or remotely, your new hire needs the right tools to do their job. To help them hit the ground running, be sure to order and configure any devices they need before their first day. That includes access to apps, from email to Slack, Zoom, Figma, and more, as required.

This step often creates bottlenecks because it requires HR, IT, security, and managers to coordinate across multiple systems. A workforce platform like Rippling gives you a single point of authority for all employee IT requirements, new hires included. AI workflows can automatically provision laptops, create Microsoft 365 accounts, assign Slack channels, enable VPN access, and notify managers when everything is ready.

This can save hours. Indeed, non-Rippling customers spend three times longer on IT setup and offboarding than those using the platform. 

Plan and communicate

Preboarding is not only about administration. It’s also about creating a clear path for a new employee’s first days and weeks. A structured employee onboarding checklist ensures responsibilities are clear internally and helps new hires understand what to expect before they arrive.

You may want to create a first-week schedule, set up a 1:1 with their manager, any meetings with their team, or even a team outing for their first day (lunch is a great option!). Prepare any resources they need, such as the employee handbook, the company's mission statement, policies, and values, and a list of their colleagues. Send them an email with all the details so they know what to expect on their first day.

Platforms like Rippling AI can also generate personalised onboarding schedules and automatically remind managers when key onboarding tasks haven't been completed.

8 things to do on an employee’s first day

Set the tone for your employee's entire time with your company by making sure they feel welcomed, informed, and confident on their first day.

1. Make sure their workspace is ready If your new hire works in the office, make sure their desk is set up with everything they need. You can consider customising their workspace with a nameplate and greeting them with a decorative welcome gift for their first day to make a good first impression.

2. Send a 'welcome to the team' email It's a good idea to send an email out to your company introducing the new hire, providing a brief bio and job description, and encouraging colleagues to pop over and say hi. This can give your new employee an early glimpse of the company culture they can expect. Learn how to write the perfect welcome to the team email with our guide.

3. Give them an agenda to help them get started It’s hard for new hires to grasp their first-day responsibilities without an agenda. Whether it’s over email or in person, give them a game plan for what to expect during their first few days on the job, including meetings, assignments, and other responsibilities.

4. Schedule a 1:1 with their manager Your new hire’s supervisor will be an important sounding board throughout their course of employment. Start the relationship off right by scheduling an initial meeting to address any questions, set expectations and clarify communication norms. Ensure the new employee feels comfortable with what the role requires and confident to give and receive feedback. 

5. Schedule a meeting with their onboarding buddy or mentor Asking a welcoming colleague to guide your new hire through their onboarding process is a good practice. Set aside time for this interaction. It doesn't have to be formal. Something as simple as grabbing a drink at a nearby coffee shop can make it a pleasant experience.

6. Have a get-to-know-you event with their team or closest peers Whether in or out of the office (or virtually), a meet-and-greet with all members of the new hire’s team breaks the ice, while ensuring the new employee knows who they’ll be working with and how to access them. 

7. Give an office tour If your new hire works in person, walk them around their new office right after they get settled at their desk. Show them the bathrooms, kitchen, and storage rooms, and give them a general sense of where to find colleagues they may need to interact with. This is also a good time to briefly introduce them to their colleagues.

8. Provide them with a list of contacts Before the day’s end, share a 'cheat sheet' of the company, including names, job titles, and contact information across all platforms, to make sure your new hire knows who to go to for specific questions.

Building momentum over the first 90 days  

A new employee’s first 90 days are about helping them understand the organisation, build confidence in their role, and develop the skills they need to succeed. It's a crucial time for the new hire and the employer; research from the CIPD and Omni RMS found that 41% of employers who recruited candidates in 2024 experienced new employees resigning within their first 12 weeks. That’s why it’s important to fine-tune this part of the onboarding process.

In their first week, begin with organisational training, where they learn about the company, its goals, purpose, and values. Then, shift to role-specific training to help them learn specific skills and information needed to meet the expectations of their job.

As they settle in, give new hires meaningful work while recognising they are still learning. New hires absorb a lot of information during their first few months on the job, so it’s no surprise that their work product won’t be perfect immediately. When assigning work, start them off slowly and encourage them to ask questions when needed. Set achievable goals that allow them to gradually take on more ownership.

Regular check-ins, mentoring and manager support are essential throughout this period. These conversations provide an opportunity to review progress, remove obstacles and adjust goals as the employee becomes more comfortable in their role.

Ongoing feedback also helps new employees understand what they’re doing well and where they can improve. Don’t forget to ask for their perspective too. New hires often bring valuable insights into how onboarding processes can be improved.

Here's how this period could break down:

90-day employee onboarding phases

Digital onboarding software: Automate the admin to improve the experience

Managing onboarding manually can create delays, inconsistencies, compliance risks, and unnecessary administrative overheads, especially as organisations grow and onboarding spans HR, payroll, IT, and operations teams. When processes are fragmented across systems and spreadsheets, small tasks like approvals, data entry, and account setup quickly create major bottlenecks.

Automating onboarding workflows cuts repetitive tasks, improves data accuracy, and speeds up employee setup from preboarding through to full productivity. It also creates a more consistent experience for new hires, ensuring nothing is missed across compliance, IT provisioning, and HR administration.

As onboarding becomes more complex, many businesses turn to workforce management platforms to centralise these workflows in one system. Platforms like Rippling can automate key onboarding steps, such as payroll setup, app provisioning, policy acknowledgements, training reminders, and employee lifecycle changes, reducing administrative load while improving consistency across teams.

Because Rippling is built on a single, unified data model, entering a new hire's information once instantly triggers the pension auto-enrolment evaluation, feeds the PAYE data to payroll, and provisions the IT hardware simultaneously. 

And it makes a real difference: the majority of companies not using Rippling spend more than five hours setting up a new employee’s computer and more than five hours setting up third-party applications, while Rippling customers can complete all onboarding steps within five minutes.

For example, with Rippling, productivity software company Superhuman cut its time spent on HR and IT tasks by 75%.

Simplify onboarding and empower your people

A successful onboarding process is about much more than simply completing paperwork. It's about giving your new hire the clarity, tools, and support they need to succeed. When you combine compliance, preparation and meaningful human connection, you create an environment where people settle in quickly, understand their role and your expectations, and feel like part of the team from their very first day.

To do this well, onboarding involves coordinating a wide range of tasks. As businesses grow or manage teams across different locations and employment arrangements, keeping all these moving parts aligned can become more difficult.

This is why many organisations turn to platforms like Rippling. By bringing HR, IT and payroll, identity management and device management into a single system, Rippling helps automate much of the administrative workload while using AI to coordinate onboarding tasks, identify missing information, trigger approvals, and keep HR, IT, and managers aligned. New hires can get set up and be productive faster, and the business can remain compliant with UK labour regulations, all without the usual back-and-forth across multiple tools. 

It frees up your HR team to focus on creating a welcoming, well-structured first experience for every employee.

FAQs

What is HR onboarding?

HR onboarding is the process of preparing a new employee to join an organisation. A robust process ensures all legal, compliance, and workplace requirements are met. It sets up payroll and access to tools and systems, among other things. Plus, it helps the employee understand their role and the culture of the company they’re joining. A good onboarding process goes a long way towards your new hire starting confidently and productively.

What are the most common employee onboarding mistakes employers should avoid?

Common onboarding mistakes include failing to complete compliance checks, delaying payroll or benefits setup, not preparing equipment and system access before an employee starts, and providing little guidance during their first days and weeks. 

A delayed, rushed or inconsistent onboarding process can leave new hires feeling unsupported. It also creates unnecessary administrative work for HR teams. Don't think of onboarding as a one-day task; regular check-ins, clear expectations, training, and feedback during the first 90 days help a new hire feel welcome and become productive faster.

Do UK employers need to enrol employees into workplace pension schemes?

Yes. Most UK employers must automatically enrol eligible employees into a workplace pension scheme and make minimum contributions under auto-enrolment rules. Employees can then choose to opt out, but only after being enrolled. 

During onboarding, you should collect the necessary details and ensure your new employee understands how the workplace pension works as part of their overall benefits package, so they can make an informed decision on whether to remain enrolled or not.
