The Ultimate Van Conversion Survey [UPDATED: Jan 2025]
This article has been updated in Jan 2025 to reflect the 2025 edition of The Van Conversion Bible and the latest data collected by Nohma.
To build up a reliable source of data for our book, The Van Conversion Bible, in 2020 we conducted a survey of the van conversion community. For the 2025 edition, we have added to this data set to create the Nohma Van Conversion Survey results. This includes:
- 1,200 responses from the 2020 van conversion survey
- 200 responses from an updated 2025 survey
- 16,000 responses from our layout configurator
- 5,000 bespoke electrical system customers
Additionally, we have extrapolated prices from the original survey to ensure they align with inflation.
The 2020 van conversion survey
The original van conversion survey asked a set of questions based on whether someone had already converted a van, or was planning to convert a van in the future, and this allowed us to separate them into two buckets: ‘van owners’ and ‘aspirational van owners’.
We asked van owners a series of questions about build cost and time, the size, make and model of the van they converted, and how people found the conversion process. We asked aspirational van owners about their current skills, as well as their concerns and their budget.
We collected data from over 1,200 people from 12th May – 31st December 2020, and the breakdown of respondents was:
The 2025 survey update
For the launch of the 2025 edition of our book, we ran an updated survey. This specifically targeted van owners, and allowed us to calculate multipliers to extrapolate certain figures. Where some cost increases followed inflation, others (such as the cost of a base vehicle) were far greater than this.
Over the past 4 years, inflation in the UK sits at 24%. In comparison, the cost of a base vehicle has increased a staggering 76%.
Layout configurator data
Our campervan layout configurator is the most used tool of its kind online. Over the past few years, we have collected over 16,000 responses. We have incorporated this data into our dataset to gain insights on:
- The facilities and features self-build van converters are looking to include in their campervans
- The size of van self-build van converters plan to convert
- How frequently they plan to use their campervan
Nohma bespoke electrical system customers
Since 2021, we have been designing and supplying bespoke electrical systems for those converting a campervan. As part of this process, every customer fills out a questionnaire with information about how their needs and requirements, which we use to design their campervan electrical system.
We have incorporated data from this questionnaire into our dataset to gain insights on:
- Most common appliances used in a campervan
- How people plan to use their campervan (off-grid vs campsites)
- Fuel type of the vehicle being converted (EV vs diesel/petrol)
