Calum and the team at Onwards did a fantastic job converting our VW Transporter LWB. It far exceeded our expectations which were already high having seen a friends van Calum also converted. The bespoke designs, quality of materials used and attention to detail on the build are second to none. Calum was a pleasure to work with - attentive, always contactable, and he even went out the way to get a part of the van I damaged repaired. I would highly recommended working with Onwards if you're wanting a high quality conversion. Thank you Calum and team!
We really never considered anywhere else to convert our van into our own home-on-wheels. The excellent standard of craftsmanship, design, creativity and quality of materials Calum and the team deliver is far beyond anywhere else we have heard of, or researched, ourselves. We are thinking of upgrading and expanding one day and will be going back for mark II ! Highly recommend.
Calum and the wider team at Onwards are outstanding and I use that adjective advisedly. It’s unusual, in my opinion, to find exceptional design, the highest standards of craftsmanship, and incredible customer service in a single package. Onwards have achieved this. We wanted a family van, privileging storage and robustness for 3 kids and a dog, while retaining style, comfort, and functionality. Calum nailed it. Efficient, considered, and a pleasure to work with, Onwards are deserving of the most enthusiastic recommendation. We could not be happier. 5 stars.

We chanced on our unique Mercedes Sprinter 4x4 at Onwards in Helston early in 2021 and fell in love with it before it was even finished. The ingenuity in the design, from solar tech to the ergonomics and timber workmanship are second to none and the van has a fantastic feel to it that makes it a real home on the road. The Onwards team are totally dedicated to creating beautiful vans and the after sales care is wonderful.
The team at Onwards were amazing to work with, our van far exceeded our expectations with every spare inch of space maximised for functionality. We provided them with some ideas for a van to meet our growing family that had outgrown our T5. They did eveything from sourcing a new van, working on various design options and absolutely smashed the build. 10/10 can't wait to use the van after the pandemic :)
