What it regulates

Implements Law 32/2006 with rules on accreditation and registration, safety training and the Subcontracting Book.

Who it applies to

Contractors and subcontractors on sites covered by Law 32/2006, with particular rules for businesses posting workers. This record focuses on prevention and site coordination.

Key provisions

Apply for the required Register of Accredited Companies entry before acting as contractor or subcontractor and report changes to identifying information within the specified period.

Article 3

Registration is valid nationally for three years and is renewable; apply within the six months before expiry. Registration does not replace continuing compliance with the requirements.

Article 6

Ensure safety training is necessary and appropriate for site duties; follow collectively agreed programmes and accreditation systems and the article’s fallback rules.

Article 12

Record each subcontract chronologically before its work begins and identify the safety and health coordinator and any changes to that person.

Article 15

Keep the Book on site until the contract work ends and retain it for five years after participation ends; notify the coordinator and representatives of entries and report exceptional extensions where required.

All text versions recorded by the BOE

Publication and effective dates are different. The table retains the dates and provisions of each recorded text version; it does not treat future transitional deadlines as requirements already applicable.

Transitional provisions and application notes

  • Registration became enforceable twelve months after 26 August 2007. The transitional provision covers documentary checks during that period and the historical exception for sites started before 19 April 2007.

    Transitional provision first
  • The transitional 10% and 20% permanent-employment shares are historical; the schedule set 30% from 20 April 2010. Apply Article 11’s calculation rules rather than reusing old percentages.

    Transitional provision second
  • Use of the temporary sheet under Law 32/2006 was allowed for three months after these regulations took effect. That period ended and does not replace today’s Subcontracting Book.
