Study: B+L Renovation 2026 Germany

The renovation markets represent the main sales segment for many product groups within the building supplies industry. At the same time, energy-efficiency renovations of existing buildings are a key component in the transition towards a climate-neutral building stock. However, these important renovation markets have come under significant pressure in recent years. Both private and commercial owners have in many cases held back on investing in existing buildings, and numerous measures have been postponed. Whilst a recovery is emerging in new-build construction, with rising building permits in residential construction and an increase in order intake, the question arises for the key renovation markets as to when a recovery will begin here too.

The study examines more than 20 renovation measures in detail with regard to frequency, motivation, choice of materials, budgets, etc., and provides historical time series for many indicators dating back to 2010. The study focuses on renovation activity by private owners, but the housing sector and renovation measures in non-residential buildings are also examined in separate chapters.

The study will be published on 29 May 2026. Orders can be placed via our website or by emailing mail@bl2020.com.
