Purpose The purpose of this paper is to investigate to what extent a consumer’s repair strategy impacts the annual costs of ownership of a washing machine and two types of vacuum cleaner. Design/methodology/approach The annual cost of ownership is determined by calculating the annual life cycle cost (LCC) for the respective devices. The annual LCCs of the different scenarios allow a comparison of the different repair strategy options. A Monte Carlo simulation is run to introduce parameter variability. The device’s failure rate is estimated by a combination of data sets on the devices’ performance. Findings Results demonstrate that the repair of the devices considered is a more favourable option over replacement. A consumer who aims for the lowest annual LCC should allow for a high number of repairs per device, without putting a maximum on the cost per repair. However, the consumer should become more cautious when a device approaches the end of its expected lifetime. Finally, the purchase of warranty can be interesting when the warranty covers a sufficiently long proportion of the device’s (expected) lifetime and when its cost does not exceed a threshold proportion of the initial purchase price. Research limitations/implications The costs for repair might be overestimated. Future research can focus on the reduction of repair costs following self-repair. Practical implications The results provide strong arguments in favour of repair instead of replacement of broken devices. Originality/value This is the first research to quantify the influence of consumer behaviour in the context of repair of devices on the ownership costs of these devices.

Repairing modern electrical and electronic equipment is becoming increasingly difficult. The encountered challenges significantly contribute to the costs associated with repair, making direct replacement of a product often the most straightforward option for the consumer. Therefore, the Benelux Union has requested a study to investigate extending product life time by exploring repairability criteria for products. The overall aim of the proposed repairability criteria is to evaluate and, if possible, quantify the ease of repair for energy-related products (ErPs) considering the economic impact from a consumer perspective. In this paper the recently developed Benelux repairability assessment method is applied to four vacuum cleaners. Other semi-quantitative methods that aim to assess the repairability of products, such as the Austrian durability label and the iFIXIT repairability scorecard, have also been applied to the selected case study products. The results are analyzed to understand the similarities and differences between the repairability assessment methods.

The overall aim of this study is to evaluate and, if possible, quantify the ease of repair for energy-related products (ErPs) considering the economic impact from a consumer perspective. In order to meet this objective, repairability criteria for ErPs are proposed. The developed criteria are in accordance with the ongoing initiative of the CEN-CELEC WG3 working on the standardization of repairability.
