Swedish Standards

Safe Water Installation

Authorised companies, certificates and deviations

Who is allowed to do Säker Vatten work, the certificate you must receive, and how any departure from the rules has to be documented — the accountability layer of the standard.

6 min read

Säker Vatteninstallation is enforced less through inspectors than through *who is allowed to do the work* and *what they must hand over*. Understanding that accountability layer is the first step to understanding the whole standard.

Authorised plumbing companies

Only an authorised plumbing (HVP) company may carry out and certify a Säker Vatten installation. To hold authorisation a company must:

  • sign a written commitment to follow the industry rules and the code of conduct;
  • employ at least one fitter who holds industry legitimation;
  • have staff with documented knowledge of the Planning and Building Act (PBL) and Boverket's building regulations (BBR);
  • carry valid liability insurance, and be approved for F-tax and registered for VAT.

Industry legitimation is issued to individual fitters and supervisors, is valid for five years after a passed examination, and is tied to both the authorised company and the ID06 system. A person cannot use it on jobs the authorised company has not approved. From the 2026:1 edition, newly authorised companies serve a six-month probation, must have at least one full-time certified fitter, and the old "supervisor" role is renamed to "authorised to sign certificates."

Authorised consultants

Design and specification can also be done under the standard by authorised consultants — heating-and-plumbing planners with documented knowledge of the rules and consultant insurance (ABK). For new builds and larger projects this puts the same discipline into the design stage, not just the installation.

The certificate you must receive

On completion the authorised company must always give the client a certificate stating that the work was done to the industry rules. It records the company, the work carried out, and the building concerned, is signed and archived, and can be printed from the Säker Vatten app. Under 2026:1 the client must receive it no later than four weeks after the work finishes. Insurers generally require installations to follow the rules in force at the time for water-damage cover to apply in full — so the certificate is a document worth keeping for a sale or an insurance claim.

When the rules can't be followed: deviations

If part of a job cannot be done to the rules — because it wasn't planned that way, or because the client chose a design that departs from them — the deviation must be documented on the certificate. For consumers, the company must explain why the rule won't be met and what the consequences are, and is obliged under the Consumer Services Act to advise against deviating. The deviation agreement is archived. A recorded deviation matters later at the final inspection, in a damage claim, or during a warranty dispute — which is exactly why honest documentation protects the homeowner.
