The Hidden Costs of Hiring an Employee in the UK

When a business budgets for a new hire, the salary is usually the first and sometimes the only number on the page. It is rarely the number that ends up on the books. Employer National Insurance, pension contributions, the cost of finding the person, the kit they need, the time your team spends getting them productive, and the weeks each year when they are on leave all sit on top of it.

None of these costs is a reason not to hire. Employing people is often exactly the right decision. But a decision made on salary alone tends to underestimate the commitment, and it makes alternatives look more or less expensive than they really are. This guide sets out each cost layer for a UK employee in the 2026 to 2027 tax year, using official figures where they exist and explaining what drives the number where they do not.

Statutory On-Costs: What You Pay on Top of Salary

Two costs are set by law and apply to almost every employee: employer National Insurance and workplace pension contributions. Neither appears on the employee's payslip as a deduction from their pay. Both are paid by you.

Employer National Insurance

For the 2026 to 2027 tax year, GOV.UK's rates and thresholds for employers (opens in a new tab) set the Class 1 employer National Insurance rate at 15% on earnings above the secondary threshold of £5,000 a year (£417 a month, or £96 a week). Eligible employers can reduce their bill using the Employment Allowance, which is £10,500 for 2026 to 2027.

Because the threshold is low, employer National Insurance applies to most of a full-time salary. The Employment Allowance helps smaller employers, but it is a single allowance across your whole payroll rather than a saving on each hire, and eligibility rules apply. Once it has been used up, every additional hire carries the full rate.

Workplace Pension Contributions

Under automatic enrolment, the minimum contributions (opens in a new tab) are 8% in total, of which the employer pays at least 3%. GOV.UK explains that these minimums are based on earnings between £6,240 and £50,270 a year before tax.

Many employers pay more than the minimum, or calculate contributions on total pay rather than on the qualifying band, to compete for staff. Your own pension policy, not the statutory floor, is what goes into the budget.

The Apprenticeship Levy for Larger Employers

If your annual pay bill is more than £3 million, the Apprenticeship Levy (opens in a new tab) is charged at 0.5% of that pay bill, reduced by an allowance of £15,000 across the year.

Most small businesses will not pay the levy, but growing companies should know where the threshold sits.

A Worked Example at the UK Median Salary

To make the on-costs concrete, take the national median. According to the Office for National Statistics (opens in a new tab), median gross annual earnings for full-time employees were £39,039 in April 2025, and median weekly earnings were £766.60.

This is an illustration, not a quote for any role. Salaries for specific jobs vary widely by occupation, region, seniority and sector, and a real offer may include a higher pension contribution, bonus or benefits. The point is the shape: statutory on-costs alone add a meaningful amount before you have advertised the role.

Recruitment and Onboarding

The CIPD Resourcing and talent planning report 2026 (opens in a new tab), based on a YouGov survey of 1,014 UK HR and people professionals in April and May 2026, puts the median cost per hire at £2,000 for employees below senior management and £3,500 for senior managers and directors. The CIPD counts resourcing technology, in-house resourcing time, advertising, agency or search fees, selection tests, the cost of offers such as vetting, and onboarding.

The CIPD itself urges caution with these medians: they come from a subsample of organisations able to estimate their costs accurately, and costs vary a great deal between sectors. Treat them as a sense of scale. A role filled through a recruitment agency typically costs more, because agencies usually charge a fee linked to the starting salary, and the exact terms are set in each agency's contract.

Recruitment also carries costs that rarely reach a budget line:

• Hiring managers' time writing the brief, screening, interviewing and deciding
• The weeks the seat sits empty while the work is absorbed by others or not done
• Onboarding: setting up accounts, training, shadowing and checking early work
• Ramp time, when the new person is paid in full but not yet working at full output

Equipment, Software and Workspace

Every employee needs the tools to do the job. For an office or hybrid role that usually means a laptop and accessories, a phone or headset where relevant, software licences priced per seat, a share of office space, and IT support to keep it all running. For home-based employees, some employers also contribute to home-working costs.

These costs depend heavily on the role. A customer support seat needs a helpdesk licence; a developer may need a higher-specification machine and paid tooling; a salesperson needs CRM and prospecting data. Price them per seat, and remember that hardware needs replacing on a cycle.

Management Time and Overheads

Someone has to manage every hire: set priorities, review work, run one-to-ones, handle performance and keep the person engaged. That time has a cost even though it never appears on an invoice. So does the administration behind each employee, from payroll and contracts to HR policies, absence records and right-to-work checks.

For a small business, this often falls on a founder or senior manager whose time is the scarcest resource in the company. It is worth estimating honestly how many hours a month the role will take to manage, particularly in the first quarter.

Leave, Sickness and Cover

Most workers on a five-day week are entitled to at least 28 days' paid annual leave (opens in a new tab) a year, the equivalent of 5.6 weeks; employers can choose to count bank holidays within that. When an employee is off sick and eligible, the employer pays Statutory Sick Pay (opens in a new tab) of £123.25 a week or 80% of their normal weekly earnings, whichever is lower, for up to 28 weeks.

Holiday pay is already inside the salary, so it is not an extra line. What it changes is output: for 5.6 weeks a year you are paying for a role that is not being done unless someone covers it. For customer-facing or time-critical work, that cover is a real cost, whether it comes from overtime, temporary staff or colleagues stretching. Many employers also pay enhanced sick pay above the statutory rate.

Notice, Churn and Hires That Do Not Work Out

• Statutory minimum notice from an employer: at least one week (opens in a new tab) if someone has been employed between one month and two years
• One week for each year of service between two and twelve years
• Twelve weeks for anyone employed for twelve years or more

Contracts often set longer notice periods, especially for senior roles. Notice cuts both ways: when an employee resigns, you may be paying for a handover period while you restart recruitment, and the full recruitment and ramp-up cycle begins again.

Turnover rates vary by sector and organisation size. In the CIPD's 2026 survey, the median labour turnover rate reported for 2025 was 4.1%, though the CIPD notes the figure comes from 310 organisations, many of them very small, and should be read with caution. Only 24% of those aware of their turnover data said their organisation calculates its cost.

Whatever your own rate, each leaver brings back the costs above: vacancy time, recruitment, onboarding and ramp. A hire that does not work out in the first months is the most expensive version of this, because you pay the full cycle twice.

Putting the Full Picture Together

Some of these are fixed and predictable; others depend on how well the hire goes. Adding them up does not make employing someone the wrong choice. It means you compare options honestly.

How the Alternatives Handle These Costs

Each alternative to direct employment moves some of these costs elsewhere and leaves others with you. Our comparison of remote hiring models covers this in depth, but in short:

• Freelancers carry their own tax, equipment and benefits, but you usually manage the work, find them yourself and have no guarantee of availability. Our comparison of a freelancer and a dedicated remote professional goes further.
• Agencies and outsourcing providers absorb recruitment and management, and usually price per hour, per task or per outcome. You trade control for convenience.
• An employer of record handles payroll and compliance for someone abroad, but recruitment, management and fit remain your job.
• A dedicated remote professional through Remoteli works full-time on your work, while Remoteli handles recruitment, onboarding and ongoing operational support.

With Remoteli, you pay one monthly subscription per professional. Fees exclude VAT, run on a monthly rolling basis with no setup fees, and cover a dedicated, full-time professional working 180 hours a month, together with recruitment, onboarding and ongoing operational support. Professionals are independent contractors, not your employees, so employer National Insurance and auto-enrolment pension do not apply to you. They work remotely and generally use their own laptop and internet connection; Remoteli does not provide equipment, and licences for your own software remain your cost, as they would for any hire.

What it does not cover matters too. You still manage the day-to-day work and provide access to your own systems and any per-seat software. Professionals take 21 days' annual leave, and new standard subscriptions do not include automatic cover while they are away, so plan for that as you would for any team member.

How to Decide

Employ directly when the role is core to your business for the long term, needs to be in your office, or carries responsibilities you want inside your own organisation. Consider a dedicated remote professional when you need full-time capacity for a well-defined role, want predictable monthly costs, and would rather not run recruitment and HR yourself. For many businesses the answer is a mix, and our guide to what to keep in-house and what to outsource helps you draw the line.
