The Onyx way
Journey of a custom adventure van build
01
Initial consulation
Be it an email or phone call, once you've gotten in touch we'll arrange a time to sit down and have an initial consultation with you where we can discuss your dream and learn about your requirements.
03
Designs and deposit
It's time to get busy designing! Once you've booked in your campervan build slot with a 10% deposit, we'll get to work with you to turn your build from a sheet specification to 3D renders and select your finishes. We'll nail down the spec and the layout, and agree all the details with you.
05
Testing
No build leaves our workshop until we're confident it will withstand the open road (or dirt track) with ease.
02
Specification and estimate
Builds develop over time, we understand that and will always be upfront with where your build is sitting within your budget. We'll work with you to create a specification that reflects your needs.
04
Let's get building
As an Onyx customer, you'll have us on hand throughout the build process. When you leave the van at the workshop, we get building! We'll keep you in the loop, and if there are any queries, additions, or changes at this point, we are always availabl to talk them through.
06
Keys in hand
Now it's time to start your adventures. We'll hand over your new adventure van, and send you to a local off-grid campsite for your first night away. This gives you a chance to test your new campervan out with us nearby, so when you forget how to turn on the hot water we can help! Then you're ready to take your van off on your adventures.
Knowledge base
Owning an adventure van is incredibly exciting, but also requires some understanding that off-grid vehicles take a certain level of skill and understanding to manage the systems on board. We're here to help you learn those systems and ensure you can go off the beaten track with confidence.
UK and beyond
We understand you're going to be taking your campervan further afield than British campsites, and we hope you'll stretch it to its limits. That's why we make sure all our builds are made from high quality components that are serviceable across Europe and beyond.
Support
At Onyx, we stand behind our work and are proud to offer a 6 month (or 10,000 km) warranty on all of our services. We understand that getting to know your new van can take time, which is why we're here to support every step of the way.
Advanced Tech
We use industry recognised components and systems in our builds. We work closely with BSPK solar to spec full Victron electrical systems ensuring you can use your van to its full potential. With ever improving LifePO4 technology, there is no need for LPG in campervans, and we take pride in installing off-grid, gas-free systems.
