Support-hours calculator (DGUV Regulation 2)
Work out the annual hours of basic support required under DGUV Regulation 2 Annex 2 (Einsatzzeiten), and how to split them. A higher specialist share is usually cheaper; a higher occupational-medicine share makes sense for health topics.
Pure office and administrative businesses almost always fall into Group III.
Specialist hours are usually cheaper; a higher specialist share lowers the cost, a higher occupational-medicine share strengthens health topics. Legally at least 20% per role.
Total basic support per year (employees × factor). Split by your focus:
Calculation: employees × the support-group factor (Group III = 0.5 h/person/year). This is the basic support; business-specific support is added on top. Up to 50 employees the Unternehmermodell applies instead, with no lower limit. Guidance, not legal advice.
How the calculation works
The legal basis is DGUV Regulation 2. It sorts businesses into three support groups by risk and assigns each group a fixed share of hours per employee and year. Office and administrative businesses sit in group III, the lowest level.
Basic support = employees × 0.5 hours per year (group III)
shared by the safety specialist and the occupational physician, at least 20 percent each
What matters is the scope: the figure covers the specialist and the physician together. How it is split is decided within the business, though since the revision on 1 January 2026 at least 20 percent must fall to each side.
Two examples
- Office with 12 employees: 12 × 0.5 = 6.0 hours of basic support per year. Split 60 to 40, that is 3.6 hours specialist and 2.4 hours physician.
- Administration with 65 employees: 65 × 0.5 = 32.5 hours per year, so 19.5 hours specialist and 13.0 hours physician. From 51 employees, standard support with a formally appointed specialist is mandatory.
What the figure does not cover
The calculator shows basic support. Not included are:
- Business-specific support, driven by actual events: relocation, new workstations, an accident, introducing remote work.
- The initial effort in year one for the walkthrough, the first risk assessment and setting up the documentation.
- Follow-on costs such as first-aider training, fire safety helpers or the inspection of electrical equipment.
How this turns into a price is explained in What does a safety specialist cost?. If you would rather not cover these hours yourself, the three support models are compared on the page external occupational safety specialist.
