Health and group benefits in the United Kingdom
Reviewed by Mellow Editorial Team, HR & payroll content team
Group benefits in the UK sit alongside — not instead of — the NHS. Employers are not legally required to offer most benefits beyond statutory minimums, but the package you put together has a direct effect on recruitment, retention and day-to-day wellbeing.
What the law already requires you to provide
Before adding any voluntary benefits, it helps to know what employees already have by right.
Every eligible employee must be auto-enrolled into a workplace pension. You must contribute at least 3% of qualifying earnings; the employee contributes at least 5%. Opting out is the employee's choice — you cannot encourage it.
Employees also receive Statutory Sick Pay when they are too ill to work, and statutory family-leave pay (maternity, paternity, adoption, shared parental) at set rates. They are entitled to 5.6 weeks of paid annual leave — 28 days including bank holidays for someone on a standard five-day week. The Employment Rights Act 2025 has strengthened day-one rights further, so protections that previously required a qualifying period now apply from the first day of employment.
These are the floor. Everything below is voluntary but increasingly expected.
Private medical insurance
The NHS provides universal coverage, but waiting times for specialist referrals and elective procedures have been a persistent concern. Private medical insurance (PMI) lets employees access consultants, diagnostics and treatment faster, typically through a network of private hospitals and clinics.
For employers, PMI is a taxable benefit in kind. You report it on a P11D by 6 July after the end of the tax year, and the employee pays income tax on the value. You also pay Class 1A National Insurance at the employer rate of 13.8% on the benefit's value. Group schemes are usually significantly cheaper per head than individual policies because the insurer prices across a pool rather than assessing individual risk.
Cover typically includes inpatient and day-patient treatment, outpatient consultations and diagnostics, and sometimes mental health support. Dental and optical are usually separate products.
Life assurance and income protection
Group life assurance — often called death-in-service — pays a lump sum to an employee's nominated beneficiaries if they die while employed by you. Cover is typically expressed as a multiple of salary. Provided it sits within an HMRC-registered group life scheme, the payout is usually free of income tax for the beneficiary, and premiums are treated as an allowable business expense.
Group income protection covers a proportion of an employee's salary if they are unable to work due to long-term illness or injury. It pays out after a waiting period (the deferred period) and can continue until the employee returns to work, reaches a defined age, or the policy limit is met. This benefit reduces pressure on your SSP obligations and provides real financial security for employees facing serious illness.
Both products are valued well above their cost in employee perception surveys. They also reduce the risk of long-term absence becoming a permanent headache for workforce planning.
Dental, optical and wellbeing benefits
Dental and optical coverage are not part of standard PMI and are normally purchased as separate group schemes. A basic dental plan covers routine check-ups, hygienist visits and a contribution toward treatment costs. Optical schemes typically cover an eye test and a contribution toward glasses or contact lenses.
Wellbeing benefits have broadened considerably. Employee Assistance Programmes (EAPs) give staff confidential access to counselling, legal advice and financial guidance, usually through a helpline or app. Gym membership subsidies, cycle-to-work schemes (which run through salary sacrifice, reducing both employee income tax and National Insurance) and mental health apps are all common additions.
Salary sacrifice arrangements — where the employee agrees to a lower gross salary in exchange for a benefit — can reduce both employee and employer National Insurance, making them tax-efficient for both parties. Cycle to work, additional pension contributions and electric vehicle schemes are the most widely used.
How to structure a benefits package that works
Start with your workforce's actual profile. A team skewed toward younger employees may prioritise flexible working and wellbeing apps over life assurance. An older workforce may place more weight on income protection and enhanced private medical cover.
Flex benefits platforms let employees choose from a menu of options up to a set allowance. They are administratively more complex but significantly increase perceived value because employees only pay for what they want.
Whatever you offer, document it clearly. A benefit that employees do not understand is a benefit that does not help you retain them. Issue a summary at onboarding, include details in your employee handbook, and revisit the package annually — both to check market competitiveness and to ensure your reporting obligations (P11D by 6 July, Class 1A NI) are being met accurately.
