NEN 7510 certification: costs and timeline in 2026
How much does NEN 7510 certification cost, and how long does it take? You need an accredited certification body and you work through the step-by-step plan from risk analysis to audit. This page gives realistic indications for healthcare organisations of different sizes.
The cost categories of NEN 7510
The total cost of NEN 7510 certification consists of three parts: implementation costs, certification costs and annual maintenance costs.
Implementation costs are the costs of setting up your system: risk analysis, documentation, technical measures and training. This is a one-off cost, but often the largest expense.
Certification costs are the costs of the external audit by the certification body. The initial certification audit is more extensive than the annual surveillance audits.
Maintenance costs are the ongoing costs of keeping the system running: internal audits, updates, training, and the annual surveillance audit.
NEN 7510 costs by organisation size
The costs vary greatly depending on the size and complexity of your organisation. Below are indications for different types of healthcare organisations.
Examples by size: small = GP practice, physiotherapy practice, small pharmacy. Medium = group practice, outpatient clinic, nursing home, mental health institution. Large = hospital, large mental health institution, health insurer, national home care organisation.
| Cost item | Small (up to 25 FTE) | Medium (25-100 FTE) | Large (100+ FTE) |
|---|---|---|---|
| Internal implementation | 100-200 hours | 300-600 hours | 1,000+ hours |
| External support | €3,000 - €10,000 | €10,000 - €30,000 | €30,000 - €100,000+ |
| Technical measures | €2,000 - €10,000 | €10,000 - €50,000 | €50,000 - €250,000+ |
| Initial certification audit | €3,000 - €5,000 | €5,000 - €10,000 | €10,000 - €25,000 |
| Total first year | €8,000 - €25,000 | €25,000 - €90,000 | €90,000 - €375,000+ |
| Surveillance audit per year | €1,500 - €2,500 | €3,000 - €5,000 | €5,000 - €15,000 |
| Maintenance per year | €2,000 - €5,000 | €5,000 - €15,000 | €20,000 - €75,000 |
| Lead time | 3-6 months | 6-9 months | 9-18 months |
These amounts are indications. Actual costs depend on your current situation, the complexity of your IT environment and the choices you make. Always request specific quotes.
What determines the cost of NEN 7510?
Current maturity
If you already have a well-functioning information security policy, the step to NEN 7510 is smaller. Organisations that start from scratch have more work to do.
Do you already have ISO 27001? Then the additional cost of NEN 7510 is limited: you add the healthcare-specific requirements to your existing system. Expect 20-30% extra on top of the ISO 27001 costs.
Complexity of the IT environment
More systems mean more work. An organisation with one EHR system and standard office automation is simpler than an organisation with dozens of connected systems, medical equipment and a complex infrastructure.
The degree of outsourcing also plays a role. Do you manage everything yourself, or do you work with external IT service providers? With outsourcing, you must assess the suppliers and make agreements about information security.
Number of locations
Multiple locations increase complexity. Every location must be included in the risk analysis and the audit. Certification costs rise because the auditor has to visit more locations.
Choices in support
You can implement NEN 7510 entirely yourself, or bring in external help. Doing it yourself saves money but costs more internal time and carries a risk of mistakes. External support costs money but provides expertise and speed.
A middle way is coaching: an adviser guides your team, but you do the work yourself. This is often the best balance between cost and quality.
How costs are spread over time
Year 1: implementation and certification
The first year is the most expensive. You build the system, implement measures and go through the certification audit. Most of the costs fall in this year.
Years 2 and 3: maintenance
After certification, costs fall. You maintain the system, carry out internal audits and go through the annual surveillance audit. The costs are a fraction of the first year. As an indication, a surveillance audit often costs around 15 to 25% of the initial certification audit.
Year 4: recertification
After three years, recertification follows. The audit is more extensive than the surveillance audit, but less than the initial certification. As an indication, recertification is often around 20 to 30% lower than the initial certification audit.
How long does NEN 7510 certification take?
A small practice is ready in 3 to 6 months, while a large hospital takes 9 to 18 months. The lead time depends mainly on how much time your team can free up and how far along you already are. Below you can read what affects the planning and what is realistic per organisation size.
Factors that affect the lead time
Available capacity: How much time can people free up? A project leader who is 50% available works faster than someone who can spare 10%.
Decision-making: How quickly are decisions made? Slow decision-making delays the entire process.
Technical implementation: Some measures take time to implement, for example new systems for logging or access management.
External dependencies: Are you waiting on suppliers? That causes delays.
Realistic planning
| Organisation size | Minimum | Average | Extended |
|---|---|---|---|
| Small (up to 25 FTE) | 3 months | 4-6 months | 9 months |
| Medium (25-100 FTE) | 6 months | 9 months | 12 months |
| Large (100+ FTE) | 9 months | 12-15 months | 18+ months |
Do not plan too tightly. Unexpected matters take time: sick team members, other priorities, disappointing suppliers. Build in at least 20% slack in your planning.
Certification costs in detail
The certification body calculates costs based on audit days. The number of audit days depends on the size of your organisation, measured in FTE, and its complexity.
Initial certification audit
The initial audit consists of two stages:
Stage 1 (document review): 0.5 to 2 days, depending on complexity. Often possible remotely.
Stage 2 (implementation audit): 1 to 10+ days on site, depending on size.
The day rate of an auditor is between €800 and €1,500, depending on the certification body.
Annual surveillance audit
After certification, surveillance audits follow every year. These are shorter than the initial audit: typically 30 to 50% of the initial audit days.
Comparing NEN 7510 certification bodies
Always request quotes from several bodies. The price differs, but that is not the only thing that matters. The real difference lies in experience with healthcare, the background of the auditor and how flexibly they can schedule.
All bodies that are allowed to certify are accredited by the Dutch Accreditation Council (Raad voor Accreditatie, RvA) . This guarantees that the certificate has value. Within that group, compare on the following points.
| Comparison point | Why it matters | Ask in the quote |
|---|---|---|
| Accreditation for NEN 7510 | Only then is the certificate recognised | Are you on the RvA list for NEN 7510? |
| Experience in healthcare | An auditor who knows healthcare asks sharper questions | How many healthcare clients do you certify? |
| Background of the auditor | Knowledge of EHRs and care chains saves explanation | Who will be my auditor and what is their experience? |
| Also ISO 27001? | Useful if you later want to combine | Can you do both standards in one audit? |
| Scheduling and flexibility | Waiting times can delay your project | How quickly can you schedule the audit? |
| Day rate and number of audit days | Determines the final price, not the rate alone | How many audit days do you estimate for my size? |
Note the last point: a low day rate with many audit days can end up more expensive than a high rate with few days. Compare the total quote, not the hourly rate.

Savings and subsidies
Combining with ISO 27001
If you also want or need ISO 27001, combine the processes. The overlap is large (80%), so you save significantly by doing both at the same time. Combined audits are more efficient.
Working with peer organisations
Small healthcare organisations can work together. Share the cost of an adviser, exchange knowledge and learn from each other’s experiences. Healthcare umbrella organisations sometimes facilitate this.
Subsidies and schemes
There are no specific subsidies for NEN 7510, but general schemes for information security or digitalisation in healthcare may apply. Check with your sector organisation or regional collaboration bodies.
Return on investment of NEN 7510
NEN 7510 costs money, but it also delivers value. Direct benefits are access to contracts that require NEN 7510, and less supervision burden from the IGJ.
Indirect benefits are harder to quantify but real: better security means a lower chance of incidents. A ransomware attack or data breach costs many times the certification costs, not to mention reputational damage.
The average cost of a data breach in the healthcare sector is internationally above €10 million for major incidents. NEN 7510 is then a modest investment.
Are you considering doing it yourself? Read implementing yourself or with an adviser. For hospitals, a different scope applies; see NEN 7510 for hospitals.
