How to compare job agency offers in the Netherlands – what to check before signing a contract?

Going to work in the Netherlands is an important decision that requires preparation and a careful review of job offers. The Dutch labour market is open to foreign workers, but unfortunately not all employment agencies operate fairly. Differences in wages, housing costs, or types of employment can be significant, so before signing a contract it’s worth knowing what to pay special attention to. Proper preparation helps you avoid misunderstandings, financial issues, and dishonest practices.

Verifying agency legality – the foundation of safety

The first step when comparing job offers in the Netherlands is to check whether the agency operates legally. For Polish companies, make sure they have a KRAZ certificate (Krajowy Rejestr Agencji Zatrudnienia – National Register of Employment Agencies). This guarantees that the agency is registered and supervised by Polish authorities.

In the Netherlands, legal employment agencies are members of organisations such as ABU (Algemene Bond Uitzendondernemingen) or NBBU (Nederlandse Bond van Bemiddelings- en Uitzendondernemingen). Membership in one of these organisations means that the agency follows fair employment rules, pays wages according to the CAO (collective labour agreement), and ensures proper housing conditions for employees.

It’s also worth checking whether the offered accommodation has an SNF certificate (Stichting Normering Flexwonen). This system certifies that housing for temporary workers meets Dutch safety and hygiene standards.

Employment conditions – under what terms will you work?

The next step is to thoroughly analyse the type of contract and employment conditions. Agencies may offer different forms of cooperation: a Polish employment contract, a Dutch temporary employment contract (uitzendovereenkomst), or self-employment (ZZP). Each of these options has different tax, insurance, and social implications.

The most common arrangement is a Dutch temporary contract, which provides health insurance, pension contributions, and wages based on CAO rates. Before signing the contract, make sure it clearly states:

• the gross hourly rate
• the number of working hours per week
• the duration of employment and possibility of extension
• how overtime and shift bonuses are calculated
• who pays for insurance and housing

If the offer doesn’t include these details and the agency avoids giving clear answers, it’s best to walk away — trustworthy companies always provide full documentation before you leave.

Pay and bonuses – compare real earnings, not promises

The hourly rate is one of the most important factors, but not always the most decisive. Some agencies advertise seemingly high wages that turn out to be much lower after deducting housing, transport, and insurance costs.

Check that your wage complies with the Dutch minimum wage (minimumloon) and includes any industry-specific bonuses set out in the CAO. In sectors like logistics, production, or horticulture, specific rates apply depending on your age and experience.

When comparing offers, calculate your net pay, i.e. how much you’ll actually receive “in hand” after all deductions. The difference between offers can amount to several dozen euros per week.

Accommodation – conditions, distance, and costs

Many agencies provide accommodation for temporary workers, but the standard and price can vary greatly. On average, housing costs range from €80 to €120 per week, though cheaper and more expensive options exist.

Before accepting an offer, ask:

• how many people share one room
• whether the accommodation has an SNF certificate
• where it is located relative to the workplace
• whether transport to work is included in the price
• who is responsible for cleaning and maintenance

Dishonest agencies sometimes overcharge for housing or offer poor living conditions. Always ask for photos and a detailed description before you go.

Health insurance – a mandatory requirement

Every employee in the Netherlands must have health insurance (zorgverzekering). If you work through an agency, it’s usually arranged automatically and the premium is deducted from your wages. If you work as a ZZP (self-employed), you must take out your own policy.

Check which insurance company manages your policy and whether customer service is available in English or Polish. Health insurance is mandatory, and failure to have it can result in an administrative fine.

Additional costs – hidden deductions in the contract

When comparing job offers, pay attention to all deductions from your pay. Besides housing and insurance, there may be other costs such as transportation to work, work clothing, municipal registration, or housing deposits.

A trustworthy agency should list all costs clearly before you sign the contract. If these details are missing or only mentioned after arrival, it’s a red flag.

Reviews and agency reputation

A good way to check an agency’s reliability is by reading reviews from other workers or contacting people who have worked with them. Online forums, Facebook groups, and Polish community websites in the Netherlands often contain honest feedback. Pay attention not only to comments about pay, but also about how workers are treated, the quality of accommodation, and support provided on site.

Reputable agencies are transparent, provide coordinator contact details, assist with paperwork, and act professionally.

How to choose the best offer?

When comparing job offers from Dutch agencies, don’t base your decision solely on the hourly rate. The employment terms, accommodation, agency legality, and assistance with formalities are just as important. The main elements to check before signing a contract include:

• legality of the agency (KRAZ, ABU, NBBU, SNF)
• contract type and guaranteed working hours
• hourly rate and actual net earnings after deductions
• standard and cost of accommodation
• health insurance and additional costs

Before making a decision, ask for a draft contract, have it translated, and make sure you understand all the terms. Only a verified and transparent offer will allow you to start working in the Netherlands safely, legally, and without stress.
