Private Medical Insurance: When is it time to move from SME to Corporate?

As businesses grow, their employee benefits need to evolve with them – and Private Medical Insurance (PMI) is no exception. 

For many organisations, an SME policy is exactly the right solution. But there can come a point when a business begins to outgrow the SME market. So, when should you consider moving to a corporate arrangement?

First, what do we mean by SME and corporate PMI? 

Put simply, SME PMI is generally designed for smaller groups of employees and tends to offer pre-packaged cover options. Corporate PMI is typically designed for larger employee populations and offers greater flexibility to shape a scheme around the workforce, benefits strategy and budget. 

Neither is inherently better. It’s about finding the right fit as your organisation grows. 

When might it be time to consider a move? 

Size is one consideration. As schemes grow (particularly as they approach or exceed 250 insured lives) options within the SME market can become more limited. 

While your existing insurer may allow you to remain on an SME arrangement, other insurers may no longer quote for a group of that size. This can leave businesses increasingly reliant on their incumbent insurer, with less opportunity to benchmark renewal terms against the wider market. 

Corporate PMI can open up more options, while offering a more modular approach to benefit design. Rather than choosing from a largely pre-packaged product, employers have greater scope to tailor cover to their workforce and health and wellbeing strategy. 

Corporate schemes can also offer a simpler pricing structure, which may make costs easier to communicate and help reduce complexity as employers prepare for mandatory payrolling of benefits in kind from April 2027. 

What about the impact on employees? 

There are some important considerations here too. 

SME schemes are typically age-rated, so the cost of cover varies with an employee’s age. Corporate schemes generally use a flat-rate structure, where employees under 65 are charged the same rate according to their membership category – such as single, couple or family – regardless of age. 

For younger employees, this can mean the cost of their PMI increases and, where the employer funds the benefit, the tax they pay on that benefit may increase too. Conversely, older employees may see the cost and associated tax liability reduce. 

This needs to be communicated carefully and balanced against the potential advantages, including greater flexibility and any enhancements to cover the employer chooses to introduce. 

Is there ever a good time to make the move? 

Timing can be one of the biggest challenges. 

SME renewal terms are often only available around six weeks before renewal, and corporate insurers may need to see these before finalising their terms. That creates a tight window for comparing options, securing internal approvals and communicating with employees. 

At Ink, we encourage clients to start exploring the question well ahead of renewal, so a decision in principle can be made before that window begins. 

Moving to corporate PMI isn’t automatically the right answer. But as your business and benefits strategy mature, it’s worth asking: 

Has your medical insurance evolved with your business – or have you outgrown the scheme you started with?
