Scaffolding in Finland for foreign contractors: paperwork and Decree 205/2009

A scaffold firm from abroad meets two sets of Finnish duties: the paperwork that must be in place before anyone enters the site, and the scaffold clauses of Government Decree 205/2009 that apply from the first lift. Each point below names the page or section it comes from.

What are the scaffolding rules in Finland?

Construction scaffolds in Finland follow Government Decree 205/2009, sections 51–68: guardrails at least 1 m high wherever a fall of more than 2 m is possible, a structural plan for site-built scaffolds, inspection before use and weekly. A foreign employer must also file a posting notice, and every worker needs a photo ID carrying a registered Finnish tax number.

What paperwork must be ready before work starts?

Finland is strict about who stands on a construction site, and the checks come from the occupational safety authority and the Tax Administration together.

  • Posting notification. The posting company must notify the occupational safety authority before work begins in Finland, using the authority's online form (notification duty). In construction there is no exemption, not even for short transfers inside one company. The notice lists the client, the builder and main contractor, and for each worker the personal identification number, the home-country tax ID and the Finnish tax number. Substantial changes need a supplementary notice before work may continue, and a missing notice triggers a negligence fee.
  • A representative in Finland. The company must name a representative with a Finnish postal address who can receive official documents for it. No representative is needed when the posting lasts no more than 10 days, counted over the last four months (employer's representative).
  • Photo ID with a tax number. Everyone working on a shared construction site must wear a visible photo ID showing name, photo, employer and tax number, and the number must be in the public tax number register (taxes and tax numbers). The duty rests on the builder, the main contractor and each employer.

How does a foreign worker get a Finnish tax number?

The Finnish Tax Administration's construction site page sets out the order:

  1. Get a Finnish personal identity code first; the tax number cannot be issued without it.
  2. Visit a tax office service point in person, with a valid passport, a residence permit or visa where one is required, and the employment contract. Book an appointment through the foreign employee registration line; groups of more than five need one.
  3. The Tax Administration recommends sending the online form two weeks before the visit. Processing takes one to three business days once all documents are in.
  4. Check that the number is entered in the public register. It is added automatically when a request covers at least 20 workers; otherwise the employer or the site's project supervisor can request the entry.

Do workers need the Finnish Safety Card?

Not by law. The Occupational Safety Card (Työturvallisuuskortti) is a one-day course with a written test, valid for five years. Its operator, Työturvallisuuskeskus, describes the training as voluntary and driven by client requirements, and said in June 2022 that courses run in 15 languages. In practice many main contractors demand it at the gate, so ask your Finnish client before the crew travels. Since 15 January 2025 no printed cards are sent; validity is checked in the online card search.

What the decree itself requires is different: section 57 of Decree 205/2009 allows erection, dismantling and alteration only under a competent supervisor, by workers given specific instruction on the work sequence, fall prevention, weather changes and permitted loads. There is no state scaffolder licence.

Which clauses of Decree 205/2009 does a scaffold crew meet?

SectionRequirement
28Guardrails where a fall of more than 2 m is possible: top rail, mid rail and a toe board, at least 1.0 m high, no vertical gap over 0.5 m under any rail
Annex 5Top rail and posts resist a 1.0 kN point load, mid rail and toe board 0.5 kN, deflection at most 100 mm
52–53Follow the system's user instructions; a structural plan when the scaffold departs from them, and always for a site-built scaffold
56A designer with at least a technical degree or technician-level qualification when the scaffold is over 10 m, relies on ties for stability, or is demanding to design, for example because it is sheeted
58Erect and strike in an order that controls the fall risk; never remove ties in a way that destabilises the rest
60Maximum load shown on a load plate or scaffold tag, with inspections recorded on the tag
63No gaps over 30 mm in a platform; 1.9 m clear between platforms, 1.75 m at supporting members
65Mobile towers: firm ground, locked wheels, height no more than three times the smallest base width, nobody aboard when moved

The parallel Decree 403/2008 on work equipment repeats the instruction duty in section 29 and covers scaffolds outside construction. How EN 12811-1 load classes work is explained in the load class guide.

Who inspects the scaffold, and how often?

Section 15 requires the structure of every working and protective scaffold to be inspected before use, and again after strong wind, heavy rain, other exceptional stress or a long idle spell. Section 16 adds a site maintenance inspection at least once a week. The site's responsible person, or someone they appoint, carries out both, with a workers' representative invited, and keeps a record (section 17). Annex 4 lists the items, from foundations and ties to toe boards and signs. Ordinary scaffolds are not on the list of equipment in Decree 403/2008 that needs an accredited inspection body. The routine is laid out in the inspection checklist.

Who enforces the rules?

Since 1 January 2026 the national Licensing and Supervisory Authority (Lupa- ja valvontavirasto) carries out occupational safety inspections; tyosuojelu.fi stays the information channel. Serious breaches go to court as occupational safety offences, and a company fine can follow. In a case the authority published on 8 January 2024, a district court fined a painting company's works manager and the company after a fall of about 1.5 m from a scaffold that lacked guardrails and a sloping access route. The court held that scaffold safety is judged as a whole, not by the height of the fall. For how Finland compares with its neighbours, see scaffolding regulations by country.

Where does ScaFix fit?

ScaFix turns wall dimensions or a PDF drawing into a 3D scaffold and a parts list in many scaffold systems. It can support a site use plan, but it is not a section 53 structural plan or a load calculation.

Planning information based on Finnish Government Decrees 205/2009 and 403/2008 and the authorities' posting guidance, not legal advice or structural approval. The decree text, the manufacturer's user instructions and the structural plan decide, and a competent person must inspect the scaffold before use.

Frequently asked questions

Do I need to report posted scaffolders to Finland?

Yes. In construction the posting notice is always required and must reach the occupational safety authority before work starts, with each worker's Finnish tax number.

Is the Työturvallisuuskortti mandatory in Finland?

No law requires it, but many Finnish main contractors make it a site condition. It is a one-day course and stays valid for five years.

How high must a scaffold guardrail be in Finland?

At least 1 metre, with a mid rail and a toe board, wherever a fall of more than 2 m is possible (Decree 205/2009, section 28).

How often are scaffolds inspected in Finland?

Before first use and after storms, heavy rain or long idle periods (section 15), and in the weekly site maintenance inspection (section 16).

Can a foreign worker get a Finnish tax number quickly?

Processing takes one to three business days once the documents are complete, but the worker needs a Finnish personal identity code first and must visit a tax office in person.
