Ergosimo & Workers' Insurance Stamps (EFKA): Who Has the Legal Obligation to Cover the Crew's Insurance?

There are cases where the owner does not hire a worker as an employee, but assigns work to a professional who has his own sole proprietorship or company and issues a normal document.

Typical examples include the following:

In these cases, the professional carries his own tax and insurance obligations as a business operator. That should not be confused with the insurance treatment of laborers working on a construction project.

If the professional works alone and invoices his own service, that is a different scenario from employing workers or a full crew on construction work that may need to be declared as a project.

That is why the actual facts of the specific case always need to be checked in practical terms.

Not every small job in the bathroom is a construction project.

Typical examples include:

In such cases, construction insurance stamps may not become an issue at all. But once the work goes beyond minor repair and becomes a real renovation or building intervention, it has to be assessed differently.

The dividing line is not always obvious to the owner. So when there is doubt, it is better to ask an accountant, an engineer, or EFKA before work begins.

Before you commission your bathroom renovation, you need to ask some specific questions.

If you are working with a contractor or technical company, the core questions are the following:

If you are bringing in individual trades yourself, you should at least ask the following:

These questions may sound bureaucratic, but they protect the owner from very practical risk.

A proper renovation quote or agreement should clarify the issue of insurance and liabilities.

Ideally, it should cover the following points explicitly:

A generic phrase such as “labor included” is not always enough. Labor is the commercial side of the work; insurance is a separate liability and should be made explicit.

Many owners think that "since I paid the handyman, it's none of my business". But this is not always safe.

If a job is treated as construction work and the insurance obligations have not been covered, the usual problems are the following:

The most serious issue is the work accident. If an uninsured worker is injured on site, the situation can become extremely serious for everyone involved.

That is why insurance is not a side detail. It is part of proper project organization.

There is a large gray area in bathroom renovation, because it can range from a very small repair to a substantial construction project.

When the scope stays very small, we are usually not talking about full EFKA project registration. But once the work becomes a real renovation, it should not be treated like a casual "day job", because EFKA obligations may come into play.

In practice, there is no single answer that fits every case. It depends on who is organizing the work, who employs the workforce, and whether the scope is a normal construction operation or a limited professional service.

The mistake is for the owner to think that "since there is a handyman, everything is his responsibility". In private construction projects, the project owner is of particular importance vis-à-vis EFKA.

An owner wants to fully renovate a bathroom. The scope includes demolition, new plumbing, new drainage, screed work, waterproofing, and new tiles.

In that scenario, the owner must check whether EFKA project registration and insurance contributions are required.

If the work is assigned to a company instead, the owner should ask for written confirmation that the company is taking responsibility for its personnel, its insurance obligations, and its documentation. If project registration or another EFKA-related process is required, the agreement should also say who handles it and who pays the corresponding contributions.

To avoid surprises, organize the points that usually create legal and financial ambiguity before the work begins.

The point is not to scare the owner. It is to know what he is undertaking and what he should ask the contractor.

The safest approach is not to leave insurance questions unresolved. If you are bringing in crews yourself, check in advance whether EFKA project registration and contribution payments are required. If you are assigning the work to a contractor or company, ask for a written statement of who is responsible for the workforce, the documents, the insurance contributions, and any EFKA procedure. `Ergosimo` is not a general-purpose solution for normal construction work. It may fit minor repairs, but a full bathroom renovation with demolition, tiling, plumbing, and plastering needs a more careful legal and insurance check. A clear written agreement is the best protection for both the owner and the crew.

The issue of worker insurance and EFKA obligations in a bathroom renovation should never be treated as an afterthought.

Small repairs may never rise to the level of a real construction-project issue. But once the scope includes demolition, tiling, plumbing, drainage, and broader building work, the EFKA side of the project needs to be checked properly.

The general rule is that, in private building work, the property owner still matters significantly from EFKA’s perspective. When a contractor or technical company is involved, responsibilities must be clarified in writing.

A proper renovation is not only technically sound. It is also legally organized, with clear responsibilities from the beginning.
