How Does Employer Health Insurance Work?
Employer health insurance works by allowing a business to arrange private medical cover for employees, giving them faster access to treatment when needed. For most UK SMEs, the process is straightforward and flexible.
The employer chooses a policy. With broker support from Pegasus Health, suitable insurers and cover levels are selected based on workforce needs and budget.
Employees are enrolled. Cover can apply to all employees, selected teams, or directors only.
Employees have access to private healthcare. Employees contact the insurer directly for consultations, tests, or treatment.
The insurer pays eligible costs. The insurer covers approved treatment costs, subject to policy terms and limits.
Employees still use the NHS; employer health insurance simply speeds up access to care.
In short, Employer health insurance allows UK businesses to give employees faster private healthcare by arranging a group policy that covers eligible treatment costs.
What Determines the Cost of Company‑Funded Health Insurance in the UK?
Employee demographics
Age is one of the biggest cost drivers. Older employee groups typically attract higher premiums, with claims risk increasing as average age rises.Business location
Group health insurance premiums are often higher in regions where the cost of private medical treatment is greater, particularly in major cities.Level of cover provided
Core inpatient‑only policies are significantly more affordable. Excluding optional benefits such as outpatient cover can reduce premiums by up to 50%, making group health insurance accessible for smaller businesses.Excess structure
Introducing an excess — either paid by the employee or the business — usually results in lower overall scheme costs.Consultant and hospital choice
Schemes that allow the insurer to guide consultant selection or limit hospital lists can generate savings of around 20%, without compromising quality of care.Choice of insurer
Each provider structures group health insurance differently. Cover levels, underwriting approach, digital services and employee wellbeing support all affect both price and value.
