Private GP service vs health insurance for employees: what is the difference?
Employers often ask me which of these they should offer. The question reflects a genuine confusion about what each product actually does, which is understandable because the marketing for both tends to be vague. Here is the practical distinction.
What health insurance covers
Private medical insurance (PMI) pays for specialist consultations, diagnostic imaging, and inpatient treatment when a clinical need has been established. The standard pathway is: employee develops a problem, sees their NHS GP, receives a referral to a specialist, and the PMI picks up the cost of the specialist appointment, any investigations, and any hospital treatment that follows.
PMI does not cover primary care. If your employee has a chest infection, a rash, back pain, or symptoms they want assessed quickly, their health insurance policy does not help them. They still need to see a GP first, and if that GP is NHS, they are still facing the same access problem as everyone else.
This is the most common misconception about employer-provided health insurance: employees assume it means they can see any doctor quickly for any problem. In practice, they often discover that PMI is specifically for the downstream specialist care, not the first point of contact.
What a private GP service covers
A private GP service provides primary care: same-day or next-day access to a doctor, consultations at home or at work, ongoing condition management, prescriptions, and referrals when needed. It sits at the front of the healthcare journey, not the specialist end.
For the great majority of health concerns that employees bring to a doctor, this is where the issue is dealt with. Most conditions seen in general practice do not result in a hospital referral. They are managed, treated, or monitored in primary care. A GP service addresses those problems directly and quickly.
How they work together
When a referral to a specialist is needed, a private GP can refer into the private system. If the employee has PMI, their insurance then covers the cost of the consultant and any further investigation or treatment. The GP service and the health insurance cover different stages of the same journey: primary care access first, specialist and hospital cover if needed.
They are genuinely complementary. An employee with both has fast primary care access and full cover for anything that goes beyond it. An employee with only PMI has cover for hospital treatment but may still struggle to get to a GP in the first place.
Cost comparison
Standard PMI for an employee runs from around £600 to £1,500 per person per year, depending on age, the size of the excess, and the level of cover. Premiums rise with average employee age and with claims history. A private GP service costs less per person per year than most PMI policies, and unlike PMI, it is used by employees regularly rather than only when something serious happens.
This matters for the perceived value of the benefit. Health insurance is something employees appreciate in principle but hope never to use. A GP service is something they use when they are ill, which is when a health benefit actually needs to deliver.
Which to prioritise
For most SMEs with a limited benefits budget, a GP service is the more immediate return, because it addresses the most common problem: employees who need to see a doctor and cannot get an appointment easily. It is the thing that affects every employee, not only those who go on to need specialist treatment.
PMI becomes the natural next step if the business wants fuller cover, particularly for older employees or for roles where competitive benefits matter in recruitment. The two products work well together, and the case for having both is stronger than the case for either one alone. But if it is a choice, start with the thing that removes the access problem most people actually face.
