This high award is once again underpinned by the latest Aengevelt customer survey: At the beginning of 2026, for the 21st time in a row, an independent renowned market research institute asked customers for whom Aengevelt provided real estate services in the previous financial year 2025 to evaluate the service quality of the brokerage house Aengevelt, which is currently celebrating its 116th anniversary.
Analogous to the study by the SZ Institute, the results confirm Aengevelt's emphasized customer orientation and particularly high customer loyalty as well as its sustainable professional core competencies:
- As in the previous year, 100% of the survey participants stated that they would "definitely" or "possibly" want to use Aengevelt again as a service provider.
- 100% of respondents would also recommend it to business associates or business partners (previous year: 99%).
- For the evaluation of its "competence in sales", Aengevelt received the grades "1" or "2" for residential properties according to the school grading system by 95% of the survey participants according to the school grading system, and 96% (previous year: 92%) for office properties.
- With regard to "quality of advice and professional competence", 96% of the survey participants gave the grades "1" and "2" (previous year: 97%), as well as for the "commitment" of employees (previous year: 97%). In terms of "seriousness", it was as well as 97% (previous year: 100%) and a stable 98% in terms of "accessibility".
The foundation for the excellent assessment of Aengevelt services, both in the current study and in the regularly conducted customer survey, is the combination of the 4. Owner generation of proven complete independence and freedom of instruction together with profound market knowledge systematically acquired over 116 years and the associated continuity. In addition, Aengevelt is an absolute exception in the industry in the broad field of dependent investment or franchise companies that are bound by instructions.
"The "Highest Corporate Customer Loyalty" seal of quality and the further excellent customer assessment confirm our emphatically independent service orientation, based on our comprehensive real estate research over decades and our goal of the highest possible market transparency," say the shareholders Dr. Lutz Aengevelt, Dr. Wulff Aengevelt, Chiara Aengevelt, Mark Aengevelt and Max Aengevelt.
