Campervan Converter in Lewes Rd, West Sussex
JMS Vehicle Conversions is a Sussex-based specialist in bespoke campervan conversions, offering high-quality craftsmanship and tailored solutions for various vehicle types.
JMS Vehicle Conversions embarked on its journey in 2014, stemming from the founders' personal challenge to acquire a quality campervan without exceeding their budget. This initial experience led to the creation of their first conversion, a Vauxhall Movano/Renault Master, which garnered significant positive attention during a two-week, ten-country trip. This success marked the beginning of their venture into professional vehicle conversions, driven by a passion for bespoke design and functional travel solutions.
The company distinguishes itself by offering a highly flexible and bespoke design service, allowing clients complete control over layout, equipment, and features to align with their specific needs and budget. Unlike many manufacturers who offer pre-made templates, JMS Vehicle Conversions prides itself on custom-built solutions, catering to a diverse clientele. Their expertise spans from undertaking minor repairs on older models, such as a 20-year-old VW T4, to crafting luxurious, five-star race transporter lorries, demonstrating a broad capability in vehicle customization and enhancement.
Based in Sussex, JMS Vehicle Conversions provides a comprehensive range of services, from simple day van modifications to full, intricate camper conversions. Their portfolio includes popular models like VW Transporters, Transit Custom, Mercedes Vito, and VW Crafters. With over 30 years of racing experience, the team also possesses unique expertise in creating specialized race vehicles and display builds, alongside their core campervan offerings. The company emphasizes high-quality craftsmanship, smart storage solutions, and stylish finishes, ensuring each conversion transforms a vehicle into a perfect, personalized campervan.

JMS did the professional parts (gas, water, electrics, shower, etc) of our campervan conversion 5 years ago. It’s always a joy to visit for a spot of van maintenance, a cup of tea, and some humour! Whether advice by email or short-notice practical help we need, I’ve no doubt we will be life-long customers!
If my campervan could talk, it’d be singing JMS Conversions' praises from the rooftops—or at least from its freshly upgraded pop-top! These legends not only gave the pop-top a glow-up but also refitted the interior head liner and the rubber trim. The result? Sleek, snug, and road-trip ready. The workmanship displayed by the JMS is sharper than a hedgehog in a tuxedo, and the service? Friendlier than a Labrador with a tennis ball. From my first point of contact with JMS, I knew my campervan was in safe hands! If you want your campervan to feel loved and leave looking sharp enough to make other vans jealous, JMS are the guys to speak to. Thanks 'little and big Mark". You are appreciated!
The lovely chaps from JMS helped me out with repairing my T5 electric roof with new sensors just before my trip around Scotland on the North500 . A genuine bunch who did an amazing job, and at a very honest price . I would not hesitate to recommend and use them again. We were very very grateful for their assistance, especially at such short notice . Lovely people, exceptional workmanship, and a pleasure to deal with . Thank you 🙏

We were looking for a company to modify our previously partially and unprofessionally converted van into a functional and beautiful camper van. From first contact to the completion of the work on the van, JMS Vehicle Conversions Ltd were flawless. They took exceptional care in understanding our needs, and their communications were clear and prompt at every step. They provided a comprehensive quote that included various options aligned with our budget. Furthermore, JMS meticulously assessed our van, rectifying previous substandard alterations to ensure safety and functionality. The team is friendly and very professional. Their level of service and workmanship has exceeded our expectations. We now have an upgraded camper van to the specifications we wanted, and we are very happy. If you are looking for a vehicle conversion, whether fully or partially, we would highly recommend them. Thank you so much to Mark and the rest of the team for the fantastic work you have done on our van.
JMS made some great amendments to my existing conversion. I had storage space, but it wasn’t easily accessible. After discussing options with Mark, we came up with ideas of how to make better use of the available space. The work was carried out to a high standard and on time. I am happy with the service and would definitely use them for converting my next van.
