How Our Data Works | CamperBrain Methodology

How our data works

CamperBrain publishes figures on what UK campervan conversions cost and what van people are looking for. This page explains where those numbers come from, so you can judge them — and cite them — with confidence.

Three datasets we collect ourselves

Most "how much does a conversion cost" content online is guesswork or recycled from a handful of forum posts. Ours isn't. Every headline figure we publish traces back to one of three datasets we build and maintain in-house:

1. The converter directory (price ranges)

We maintain a directory of UK campervan conversion companies, capturing the build types they offer, the regions they serve, and — where a company publishes or shares it — their price ranges. Aggregated across the directory, this is where our conversion cost figures (by build type and region) come from. We report ranges and medians, and we state the sample size and collection window on any page that uses them, because a price range from a handful of converters means something different from one drawn across the whole country.

2. Quote-request demand (what people want)

When people use CamperBrain to request quotes, we see — in aggregate — what kind of conversions the UK is actually asking for: which regions, which build types, which budget bands. We publish this only as anonymised, aggregated trends. We never publish or share an individual enquiry, personal details, or anything that could identify a person or a specific converter's private pricing.

3. Gear price tracking (what kit costs over time)

We track the prices of campervan gear — leisure batteries, solar, fridges, heaters, and the rest — on a regular sweep, building a price history rather than a one-off snapshot. That's what lets us say when something is genuinely cheaper than usual, or how the cost of a component has moved across a year.

How we handle the numbers

We show our working. Any page built on these datasets states what it's measuring, the sample size, and the collection window.
We separate ours from others'. A figure that comes from our data is labelled as ours; a figure from an external source is linked to that source.
We update on a schedule. Our flagship cost figures are refreshed from the directory on a quarterly cadence, and gear prices are refreshed on each sweep, so the numbers reflect a live market rather than a frozen snapshot.
We aggregate to protect privacy. Demand data is only ever published as trends across many enquiries, never individually.

Citing CamperBrain data

Journalists, researchers and writers are welcome to cite our figures. Please attribute them to CamperBrain with a link to the page the figure appears on, and include the year (for example: "CamperBrain, 2026"). If you'd like context, a comment, or a specific cut of the data for a story, our founder Joe Tannorella is happy to help — reach us at hello@camperbrain.com.
