Wkb in 2026: what changes for installers?

The Building Quality Assurance Act (Wkb) is no longer a thing of the future - it is simply the standard. Yet many installation companies still run into the same questions: what really needs to be in the file, who is responsible for what, and how do you prevent a handover from getting stuck on a missing document?

In this article we keep things practical. No reciting legal articles by heart, but what it concretely means for the way you record and hand over your work.

The consumer file is mandatory

The most important point for the installation sector: at handover you deliver a file that allows the client to demonstrate that the work complies with the regulations. Think of drawings, product declarations, the final inspection and an operating manual for the installation.

That file does not have to be technically complicated, but it does have to be complete, findable and transferable. A folder on a desktop or a series of loose emails rarely suffices in practice.

A file you cannot show within thirty seconds basically does not exist as far as an inspector is concerned.

What this means for your workflow

• Record during the work, not afterwards - photos and forms on site save hours of paperwork.
• Link documents to the object, not to a person or mailbox that leaves later on.
• Make sure the client can access the file themselves, even eight years from now.
• Keep an audit trail: who added or changed what and when.

This is exactly where a digital file helps. By linking everything to the object and unlocking it behind a single QR code, the file is always up to date and transferable - whether the handover is today or only next year.

Start small, but start now

You don't have to digitise your entire archive in a single weekend. Start with the ongoing projects and build out from there. The gain is in consistency: one way of recording that your whole team follows.
