Corporate wellbeing strategy for large organisations: the complete guide

Most wellbeing advice is written for employers in general. Large organisations face a different problem. When you have thousands of people spread across sites, business units, shift patterns and sometimes countries, the challenge is rarely a lack of initiatives. It is making sure the right support reaches everyone, that it is governed and funded properly, and that you can prove it is working.

This guide is for HR directors, heads of reward and benefits, wellbeing leads and procurement teams in organisations with 250 or more employees. It covers how to structure, buy, roll out and measure a corporate wellbeing strategy at scale. If you are starting from scratch, our step-by-step guide to building an employee wellbeing strategy covers the fundamentals.

Key takeaways

• Poor mental health costs UK employers an estimated £51bn a year, and Deloitte estimates a return of around £4.70 for every £1 spent on supporting employee mental health.

• In large organisations, the biggest risks are fragmented provision and weak governance, not a lack of initiatives.

• Give wellbeing an executive sponsor, a cross-functional steering group and a single budget line.

• Bring support together behind one clear front door, usually an Employee Assistance Programme (EAP), and make it easy for frontline, shift and remote staff to reach.

• Train managers at scale. Only 29% of employers do, yet trained managers are far more confident spotting the signs of poor mental health.

• Report to the board on a small, consistent set of KPIs.

Why corporate wellbeing is different at scale

In a small business, the owner may know everyone by name and spot when someone is struggling. In a large organisation, wellbeing has to work through systems, policies and hundreds of managers. The most common challenges are:

• Fragmented provision. Different sites or acquired businesses often hold their own contracts for EAP, occupational health, health cash plans and apps. Employees get uneven support, and nobody has a full picture of cost or usage.

• Uneven access. Office-based staff tend to use digital benefits most, while frontline, shift and field-based employees can be the hardest to reach.

• Many stakeholders. HR, occupational health, health and safety, reward, internal communications, DEI and finance each hold part of the picture.

• Data in different places. Absence, engagement, EAP and occupational health data sit in separate systems, making it hard to see where risk is building.

• Greater scrutiny. Boards, investors and procurement teams expect evidence, value for money and robust data protection.

A corporate wellbeing strategy pulls these strands together into one approach that is owned at senior level and measured consistently.

The business case for investing in wellbeing

Wellbeing spend in large organisations competes with other priorities, so the case needs to be made in financial terms. The UK evidence is strong:

• Poor mental health costs UK employers around £51bn a year. Presenteeism, where people work while unwell and below their usual capacity, is the largest share at around £24bn (Deloitte, 2024).

• Deloitte’s review of 26 sources found employers get back around £4.70 in productivity for every £1 spent on supporting employee mental health.

• Average sickness absence reached 9.4 days per employee in 2025, up from 5.8 days before the pandemic. Mental ill health is the most common cause of long-term absence, cited by 41% of employers (CIPD, 2025).

• 964,000 workers suffered from work-related stress, depression or anxiety in 2024/25, with 22.1 million working days lost (HSE).

• Since 6 April 2026, Statutory Sick Pay is payable from the first day of sickness absence and the lower earnings limit has been removed, which raises the direct cost of short-term absence for many employers.

To build your own case, combine your absence cost per employee, staff turnover and replacement costs, and engagement or productivity data.

Set up governance that works across the whole organisation

Wellbeing fails in large organisations when it belongs to everyone and no one. Put a clear structure in place.

An executive sponsor

A board-level or executive sponsor, often the Chief People Officer, gives wellbeing authority, protects its budget and makes sure it appears in board reporting.

A cross-functional steering group

Bring together HR, occupational health, health and safety, reward and benefits, internal communications, finance and representatives from major business units or regions. Meet quarterly to review data, priorities and provider performance.

Local leads and wellbeing champions

Nominate a lead for each site, region or business unit, supported by trained champions. They adapt central plans to local needs and feed back what is and is not working.

One policy and one budget

A single wellbeing policy and a central budget line, with local discretionary funds if needed, stops duplication and makes value for money easier to show.

Use your data to find where risk sits

Large organisations hold plenty of data. The challenge is joining it up so you can see which teams, sites or roles need the most support. Look at:

• Absence by site, business unit, role and reason, especially long-term mental health absence.

• Anonymised EAP usage reports, showing which issues come up most and which groups are under-using support.

• Occupational health referrals and outcomes.

• Engagement and pulse survey results, including questions on workload, management support and psychological safety.

• Staff turnover, exit interview themes and grievance trends.

The HSE’s Management Standards Indicator Tool, a free staff questionnaire, can help you compare the main causes of work-related stress across different parts of the business.

Meet your legal duties and recognised standards

Every UK employer has the same core legal duties, but large employers face more scrutiny and are expected to go further.

Health and safety law.

Under the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999, employers must assess risks to health, including work-related stress, and act on them.

HSE Management Standards.

The HSE’s framework covers six areas linked to work-related stress: demands, control, support, relationships, role and change.

Equality Act 2010.

Employers must make reasonable adjustments for disabled employees, which can include people with long-term mental health conditions.

ISO 45003.

The international guidance standard on managing psychosocial risks at work, published in 2021, which many large organisations use to structure their approach.

Thriving at Work.

The government-commissioned review (2017) set six core standards for all employers, and enhanced standards for public sector employers and companies with more than 500 employees, including internal and external reporting on mental health.

Consolidate providers and create one front door

Many large organisations have built up a patchwork of support over time through acquisitions, local decisions and one-off initiatives. Employees are left unsure where to go, and support is duplicated in some places and missing in others.

Audit what you have.

List every wellbeing contract, its cost, who it covers, its renewal date and its usage.

Remove overlap.

Overlapping counselling services, apps or helplines can usually be consolidated.

Create one front door.

Give employees a single number, app or portal that routes them to the right support, whether that is counselling, legal or financial information, a GP appointment or occupational health.

Tier your support.

Combine prevention (education, apps and campaigns), early intervention (EAP, manager support and counselling) and specialist support (occupational health, clinical treatment and critical incident response).

An Employee Assistance Programme (EAP) is often the backbone of this model because it offers confidential, 24/7 support across a wide range of issues and can connect employees to other services.

What to look for when choosing a corporate wellbeing provider

For a large organisation, a provider has to work at scale as well as at the point of care. Ask these questions during procurement:

Access.

Is clinical support available 24/7 by phone, video, chat and app?

Clinical quality.

How are counsellors qualified, supervised and accredited, and how quickly can employees start therapy?

Breadth.

Does it cover mental, physical, financial and legal wellbeing, and does it support managers as well as employees?

Critical incidents.

How quickly can the provider respond, on site or remotely, after a traumatic event?

Reporting.

What anonymised management information will you receive, how often, and can it be split by business unit or site?

Account management.

Will you have a named relationship manager and regular reviews? Launch and engagement. What launch support, communications materials and ongoing campaigns are included?

Data protection.

How is personal and health data handled under UK GDPR?

Reach.

Can it support international teams, multiple languages and deskless workers?

Roll out support across every part of the workforce

Phase the rollout

Pilot in one or two business units, learn from the results, then roll out by region or division. Align launches with your internal communications calendar.

Reach frontline and shift workers

Use posters with QR codes, payslip inserts, toolbox talks, shift briefings and mobile apps rather than relying on email and the intranet. Make sure support is available outside office hours.

Support hybrid, remote and international teams

Offer digital access through an app such as the Wisdom app [LINK: Wisdom app page], give managers of dispersed teams clear guidance, and check that support covers every time zone and language you need.

Keep promoting it

Awareness drops after launch. Plan year-round campaigns linked to awareness dates and seasonal pressures, and keep reminding people that support is confidential. Our article on employee engagement has more ideas for keeping people involved.

Equip managers to support wellbeing at scale

Line managers are often the first to notice that someone is struggling, but many feel unprepared. Only 29% of employers train managers to support staff with mental ill health. Where they do, 63% of managers feel confident spotting the signs, compared with 45% where they do not (CIPD, 2025).

• Make mental health awareness training part of core management development rather than a one-off, for example through Wisdom Academy [LINK: Wisdom Academy page].

• Give managers a dedicated support line [LINK: HR and management support page] for advice on difficult conversations.

• Provide simple guides on policies, escalation routes and signposting.

• Include wellbeing in manager objectives and one-to-ones.

• Look after managers’ own wellbeing, as they often absorb pressure from above and below.

For practical steps managers can take day to day, see our guide to building a mentally healthy workplace.

Measure impact and report to the board

Choose a small set of KPIs, track them consistently, and report at least quarterly to your steering group and once a year to the board.

Sickness absence rate (overall and mental health).

Shows whether absence is rising or falling, and where. Find it in your HR or absence system.

Long-term absence cases and return-to-work rate.

Shows how well early intervention is working. Find it in HR and occupational health data.

EAP utilisation by site and issue.

Shows awareness, reach and emerging issues. Find it in your EAP management reports.

Engagement and wellbeing survey scores.

Shows how supported employees feel. Find it in your survey platform.

Staff turnover and regretted leavers.

Shows the impact on retention. Find it in your HR system.

Manager training completion.

Shows capability across the organisation. Find it in your learning system.

Cost per employee and estimated return.

Shows value for money. Find it in finance and provider data.

Present results alongside the business story: where risk has reduced, what changed and what you will do next. Larger employers can also publish a summary in their annual report, in line with the Thriving at Work recommendation on reporting.

Common pitfalls to avoid

• Launching initiatives without data on what employees need.

• Leaving frontline and shift workers with less access than office staff.

• Treating wellbeing as a benefit rather than tackling causes such as workload, job design and management practice.

• Running several overlapping providers with no single view of usage.

• Measuring activity, such as webinars run, rather than outcomes.

• Letting the strategy drift after launch without regular review.

Frequently asked questions

What is a corporate wellbeing strategy?

A corporate wellbeing strategy is an organisation-wide plan for supporting employees’ mental, physical, financial and social wellbeing. In a large organisation, it sets out who owns wellbeing, how support is funded and delivered across sites and business units, which providers are used, and how impact is measured and reported to senior leaders.

How is a corporate wellbeing strategy different from a general wellbeing strategy?

The principles are the same, but large organisations need stronger governance, a single view of providers and spend, ways to reach dispersed and frontline workforces, and consistent reporting to the board. The focus shifts from choosing initiatives to making support work reliably at scale.

Who should own wellbeing in a large organisation?

Wellbeing works best with an executive sponsor, usually the Chief People Officer or HR director, supported by a cross-functional steering group covering HR, occupational health, health and safety, reward, communications and finance, plus local leads in each site or business unit.

What is the return on investment of corporate wellbeing?

Deloitte’s 2024 research found that UK employers get back around £4.70 in productivity for every £1 spent on supporting employee mental health. Returns vary by organisation, so track absence, turnover and engagement before and after changes to measure your own.

What legal duties do large UK employers have for employee wellbeing?

All UK employers must assess and manage risks to health, including work-related stress, under health and safety law, and make reasonable adjustments for disabled employees under the Equality Act 2010. Large employers are also encouraged to follow the HSE Management Standards and ISO 45003, and to report on mental health as recommended by the Thriving at Work review.

How do you measure the success of a corporate wellbeing programme?

Use a small set of KPIs such as sickness absence rates, long-term absence and return-to-work rates, EAP utilisation, engagement survey scores, staff turnover and manager training completion. Review them quarterly and report to the board at least once a year.

How can large employers reach frontline and shift workers?

Use channels that do not rely on email or the intranet, such as posters with QR codes, payslip inserts, shift briefings and mobile apps. Make sure support, including counselling, is available 24/7 so people can use it outside standard office hours.

What should large organisations look for in a corporate EAP provider?

Look for 24/7 clinical access by phone, video and app, qualified and supervised counsellors, critical incident support, support for managers, anonymised reporting by site or business unit, a named relationship manager, strong data protection and support for international or multilingual teams.
