Fees

How much do you pay per employee?

In principle, employers pay a fixed amount per employee. This ‘flat-rate minimum contribution’ is the same for every employee, regardless of whether they are required to see the occupational physician periodically for health monitoring due to their job or not.

The amount of this contribution depends on your fee category. There are five fee categories, based on:

• Your organisation’s primary activity (reflected in the NACE code).

• The number of employees in your organisation.

The table below gives an overview of the minimum annual contribution per employee, depending on the number of employees and your organisation’s fee category.

Fees applicable from 1 January 2025 to 31 December 2025.

You pay the minimum flat-rate contribution per employee registered through Dimona for a full calendar year.

If an employee didn’t work for you for a full calendar year, the contribution will be calculated pro rata.

Note: if the employee received a medical examination, took a training course or used the Check-In Tool, for example, during their period of employment, the contribution will be charged for the full year, as laid down by law.

What are prevention units?

Prevention units are a kind of points system for companies in categories A, B and C+.

• A companies: More than 1,000 employees, with a level 1 internal risk prevention advisor

• B companies: Between 200 and 1,000 employees, with a level 2 internal risk prevention advisor

• C+ companies: Fewer than 200 employees, with a level 1 or 2 internal risk prevention advisor

For these companies, the total flat-rate contribution they must pay is converted into prevention units (PUs). One prevention unit has a fixed value and can be used for various services. Typically, one prevention unit corresponds to 1 hour worked by our experts. And yes, you’ve guessed it, that’s determined by law too.

• Services provided by a risk prevention advisor = 1 prevention unit

• Services provided by an occupational physician = 1.25 prevention units

• Services provided by a nurse or assistant risk prevention advisor = 0.75 prevention units.

In 2025, 1 prevention unit is equivalent to 194.04 euros.

Prevention units are initially used for ‘priority activities’ such as:

• health monitoring (medical examinations),

• psychosocial support (stress, burnout, aggression, trauma).

Secondly, they can be used for ‘recommended activities’ such as:

• ergonomics,

• safety at work,

• flu vaccinations,

• supporting a healthy lifestyle,

• training

If you use your prevention units for periodic health monitoring, you will obviously have less budget to use for other well-being needs within your company. If you want to use your PUs as efficiently as possible, we can work together to determine the best way to allocate them.

Tip: clients can find all the details on MyMensura under ‘fee calculation’: NACE code, fee per employee and remaining prevention units.

What is the basic package?

If you’re a smaller company, you can use a fixed basic package, regardless of the size of your organisation. This basic package includes – as the name suggests – all the basic activities and services you would expect from an external service. Specifically, it’s for:

• Companies in category C-: fewer than 200 employees + a basic level (level 3) internal risk prevention advisor.

  Note: If you have a level 1 or 2 internal risk prevention advisor, you fall into category C+, which follows the same rules as A and B companies.

• D companies: fewer than 20 employees + the employer acts as risk prevention advisor.

For these employers, the external service provides a basic package of services in return for the flat-rate contribution. The price of the basic package is the cost per employee (see above), and includes:

• active participation in the risk assessment and the development of a policy plan,

• provision of health monitoring,

• provision of assistance following a serious work accident,

• spontaneous consultations,

• mental wellbeing support,

• etc.

What if you want more services than are included in the basic package or if you’ve run out of prevention units?

What if you want or need to use certain services, but they’re not included in the basic package (C-/D), or if you don’t have enough prevention units (A/B/C+)? In such cases, the services will be charged for separately as shown below. Again, these fees are laid down in law.

Fees applicable from 1 January 2025 to 31 December 2025.
