Most employers have never formally audited their benefits. They know roughly what they offer, they know roughly what it costs, and they assume employees are reasonably happy. But assumption is expensive. Research from Isio and YouGov (2023) estimates that UK employers waste £15 billion a year on benefits that employees do not use, do not value, or do not even know about.

If you have not reviewed your benefits package in the last 12 months, this guide will walk you through a structured audit, step by step.

What is a benefits audit and why does it matter?

A benefits audit is a systematic review of every benefit your organisation provides, covering what you offer, what it costs, who uses it, and how it compares to the market. It answers a straightforward question: are we getting value from what we spend on our people?

Most organisations drift into their benefits package over time. A pension scheme set up at incorporation, private medical insurance added after a key hire asked for it, a cycle-to-work scheme launched because a broker suggested it. The result is a patchwork, not a strategy.

A proper audit turns that patchwork into a clear picture. It tells you where you are overspending, where you have gaps, and where small changes could make a significant difference to recruitment, retention, and employee wellbeing.

The numbers support this. According to CIPD's 2023 Reward Management Survey, 68% of employers lack insight into how employees value their benefits. And REBA's 2023 Employee Wellbeing Research found that 49% of employers do not regularly review the effectiveness of their benefits spend. That is a lot of money going unchecked.

When to run a benefits audit

You should audit your benefits at least once a year, ideally timed to feed into your annual budgeting cycle. Beyond that, there are several triggers that should prompt a review:

  • Renewal season. If your private medical insurance, group life, or income protection is up for renewal, audit first so you negotiate from a position of knowledge.
  • Rapid headcount growth. What worked for 20 people rarely works for 80. Benefits that were manageable at a small scale can become disproportionately expensive or administratively burdensome.
  • Post-acquisition or merger. Harmonising benefits across two organisations requires a clear picture of what each side offers.
  • Regulatory changes. Updates to auto-enrolment thresholds, statutory sick pay rates, or employment law (such as the Employment Rights Act 2025) can shift the baseline your benefits sit on top of.
  • High turnover or recruitment difficulty. If you are losing people or struggling to hire, your benefits package may be part of the problem.

The 7-step benefits audit process

Step 1: Document everything you currently offer

Start with a complete inventory. This sounds obvious, but most organisations cannot produce a single document that lists every benefit they provide. Benefits sit across different systems, managed by different people, sometimes with different eligibility rules.

Build a spreadsheet with the following columns:

  • Benefit name
  • Provider or administrator
  • Eligibility (all employees, by tenure, by grade, by location)
  • Employee contribution (if any)
  • Employer cost
  • Contract or renewal date
  • Last reviewed

Include everything: pension, insurance products, health and wellbeing benefits, leave policies, flexible working arrangements, learning budgets, salary sacrifice schemes, recognition programmes, perks, and any informal benefits (such as early Friday finishes or birthday leave).

Do not overlook statutory entitlements. You need to know where your offering sits relative to the legal minimum.

Step 2: Calculate the true cost

Once you have the inventory, attach real numbers. For each benefit, calculate:

  • Total annual cost to the employer. Include premiums, employer contributions, administration fees, and any tax or National Insurance implications.
  • Cost per employee. Divide total cost by the number of eligible employees, not just those who have enrolled.
  • Cost per participating employee. Divide total cost by the number who actually use the benefit. This figure is often surprisingly high.

Do not forget hidden costs. Administering a benefits programme takes time. If your HR team spends 10 hours a month managing a cash plan that 15% of employees use, that time has a cost.

Add it all up. The total figure, your benefits spend as a percentage of payroll, is a key metric. For most UK employers it sits somewhere between 10% and 25% of base salary costs, depending on the generosity of the pension and whether private medical insurance is included.

Step 3: Check utilisation

This is where most audits reveal their biggest surprises. For every benefit, find out how many eligible employees are actually using it.

For insured benefits (PMI, life insurance, income protection), your provider or broker should be able to supply utilisation data and claims experience. For salary sacrifice schemes, check enrolment numbers. For your Employee Assistance Programme (EAP), ask the provider for usage reports, which most supply quarterly.

Some benefits are harder to measure. Flexible working, for instance, does not have a simple "used or not used" metric. For these, you will need to rely on employee feedback (Step 4).

Red flags to watch for:

  • Benefits with less than 20% take-up among eligible employees
  • Benefits where cost per participating employee is disproportionately high
  • Benefits that employees do not know exist (more common than you think)

Step 4: Survey your employees

Data tells you what is happening. Employees tell you why.

Run a short, focused survey covering:

  • Awareness. For each benefit, do employees know it exists? Do they understand how to access it?
  • Perceived value. Which benefits do employees value most? Which would they trade away?
  • Gaps. What would employees like that you do not currently offer?
  • Satisfaction. How do employees rate their overall benefits package?

Keep it anonymous to get honest answers. Aim for a participation rate above 60% to make the results meaningful. If you have fewer than 50 employees, consider supplementing the survey with a few informal conversations.

The gap between what employers think employees value and what employees actually value is often significant. Many employers overestimate the importance of "nice to have" perks and underestimate the weight employees place on financial security, flexibility, and mental health support.

Step 5: Benchmark against market standards

Your benefits do not exist in a vacuum. They exist in a labour market where candidates and employees compare your offering against alternatives.

Key benchmarking sources for UK employers:

  • CIPD Reward Management Survey (annual). Covers pay, pensions, and benefits across sectors and organisation sizes.
  • REBA Employee Wellbeing Research (annual). Focused on health and wellbeing benefits.
  • Mercer and Willis Towers Watson benchmarking reports. More detailed but often behind a paywall.
  • Your broker. A good employee benefits broker will have benchmarking data for your sector and size band. If they do not, that is worth noting.
  • Job adverts. Look at what competitors are advertising. It is free, it is current, and it tells you what the market considers table stakes.

Focus your benchmarking on the benefits that matter most to recruitment and retention in your sector. For a tech company, that might be flexible working and learning budgets. For a manufacturing business, it might be pension contributions and income protection.

Step 6: Identify gaps and overlaps

With your inventory, cost data, utilisation figures, employee feedback, and benchmarking in hand, you can now map the landscape.

Gaps are areas where your provision falls short:

  • Benefits your employees want that you do not offer
  • Areas where you meet the statutory minimum but lag behind market norms (for example, offering only the auto-enrolment minimum pension contribution when competitors offer 6% or more)
  • Demographics or employee groups that are underserved (remote workers, part-time staff, younger employees without dependants who get little value from family-oriented benefits)

Overlaps are areas of duplication or waste:

  • Multiple benefits serving the same need (for example, an EAP, a separate mental health app, and a wellbeing allowance all aimed at mental health, with none used well)
  • Benefits designed for a workforce profile you no longer have
  • Legacy benefits maintained out of inertia rather than strategy

Step 7: Prioritise actions by impact and cost

Not every gap needs filling immediately, and not every overlap needs eliminating. Rank your findings by two dimensions:

  • Impact on employees. How many people does this affect? How strongly do employees feel about it? Does it address a retention or recruitment risk?
  • Cost to implement or change. What is the financial cost? What is the administrative burden? Are there contractual constraints on timing?

Plot your actions into four categories:

  • High impact, low cost. Do these first. Often includes improving communication about existing benefits, adjusting eligibility rules, or renegotiating terms with providers.
  • High impact, high cost. Build a business case and schedule for budget approval.
  • Low impact, low cost. Do these when convenient but do not prioritise them.
  • Low impact, high cost. Deprioritise or remove these.

What to include in a benefits audit

A thorough audit covers every category of your employee offering. Here is a checklist.

Pension

  • Auto-enrolment compliance (contribution rates, eligible jobholders, postponement)
  • Employer contribution rate versus market benchmarks
  • Salary sacrifice arrangement (if applicable, and whether it delivers NI savings)
  • Employee understanding of their pension and engagement with the scheme
  • Provider fees and fund performance

Health and wellbeing

  • Private medical insurance (PMI): cover level, excess, eligibility, claims ratio
  • Health cash plans: utilisation and cost per claim
  • Employee Assistance Programme (EAP): usage rates, services included, employee awareness
  • Mental health support: whether provision is adequate given your workforce profile
  • Occupational health services
  • Eye care vouchers, flu vaccinations, health screenings

Leave policies

  • Annual leave entitlement versus market norms (UK average for SMEs is around 25 days plus bank holidays)
  • Parental leave: enhanced maternity, paternity, shared parental leave, and adoption pay
  • Sick pay: statutory only or enhanced, and for how long
  • Compassionate and bereavement leave
  • Other leave types: volunteering days, study leave, sabbaticals

Financial benefits

  • Salary sacrifice schemes: childcare vouchers (closed scheme), cycle to work, electric vehicles, pension
  • Income protection and group life insurance: cover level, waiting period, terms
  • Life insurance: multiple of salary, whether it reflects current workforce
  • Financial education or guidance programmes
  • Discount platforms and cashback schemes

Flexibility

  • Hybrid and remote working policies
  • Flexible hours, core hours, compressed working weeks
  • Part-time and job-share options
  • Whether flexibility is genuinely available or only on paper

Learning and development

  • Training budgets (per head or on request)
  • Professional qualification support
  • Conference and event attendance
  • Internal mentoring or coaching programmes

Recognition and rewards

  • Bonus structures (performance, company, discretionary)
  • Long-service awards
  • Peer recognition schemes
  • Non-monetary recognition (extra leave, experiences, public acknowledgement)

How to present audit findings to leadership

Your audit is only useful if it leads to decisions. When presenting to the board, senior leadership, or finance:

Lead with the numbers. Total benefits spend, cost per employee, and the percentage of payroll. These anchor the conversation.

Show utilisation alongside cost. A benefit costing £40,000 a year with 12% utilisation tells a clear story without needing much commentary.

Use employee voice. Select two or three direct quotes from your survey that illustrate key themes. Data persuades, but employee quotes make it real.

Present recommendations as trade-offs, not a wish list. "We can improve mental health support by reallocating £8,000 from the underused discount platform" is more compelling than "we should add a mental health benefit."

Be specific about timing and cost. Leadership teams approve actions, not observations. Each recommendation should include an estimated cost, an implementation timeline, and the expected outcome.

One-off audit versus continuous benefits intelligence

A benefits audit is a point-in-time exercise. It gives you a snapshot, which is valuable, but it ages quickly. Employees leave. New providers enter the market. Legislation changes. What looked competitive in January may look average by September.

The alternative is continuous benefits intelligence: ongoing monitoring of your costs, utilisation, employee sentiment, and market position. This does not have to be complicated. It means checking your key metrics quarterly rather than annually, running pulse surveys instead of waiting for the annual engagement survey, and keeping a live view of how your package compares.

Organisations that move from periodic audits to continuous monitoring make better decisions, react faster to problems, and spend less time scrambling before renewals.

Getting started

If this process feels like a lot to take on alongside everything else on your plate, you are not alone. Most HR teams know they should audit their benefits but struggle to find the time to do it properly.

PerkIQ's Benefits Healthcheck walks you through a structured audit in about five minutes. It scores your current package, identifies gaps, benchmarks you against UK market data, and gives you a prioritised action plan. It is free to start and designed for exactly this purpose.

Whether you use a tool or a spreadsheet, the important thing is to start. An imperfect audit completed is worth far more than a perfect audit that never happens.
