16 Campervan Converters in Hertfordshire

Expect a UK-wide range of £15,000 to £60,000 for a full professional build, excluding the van. A simple weekender layout with basic electrics sits at the lower end of that scale. In practice, a high-spec build with off-grid power, custom cabinetry, and [a pop-top roof](/services/pop-top-roofs) can easily push past £50,000. Always get a detailed, itemised quote before you commit.

Most full conversions take between 8 and 16 weeks from when the van enters the workshop. This can change. A simple build might be quicker, while complex electrical systems or bespoke furniture can add several weeks to the timeline. For most builders, the main factor is their current schedule and the availability of key parts, so it's wise to book your slot well in advance.

You'll find most workshops are very familiar with popular medium and large panel vans. This means Ford Transits, VW Transporters, and Mercedes Sprinters are common sights. Many also handle Citroen Relays, Peugeot Boxers, and Fiat Ducatos, which share the same chassis. If you have a less common base vehicle, call ahead to confirm the converter has experience with your specific model.

It almost always starts with a consultation to discuss your ideas and budget. From there, the converter creates a detailed design and quote for your approval. Once you agree, the build phase begins, which can take several months. Most builders provide regular updates with photos. The final step is the handover, where they walk you through all the new systems before you drive away.

Yes, and you absolutely should. Most professional converters welcome workshop visits, but you must book an appointment first as they are active work sites. A visit lets you see the quality of their craftsmanship up close and meet the team who will be building your van. This is the best way to gauge if they are the right fit for your project and your vision.

Look beyond just the price tag. A strong portfolio showing previous builds similar to what you want is crucial. Check their online reviews and ask for testimonials from past clients. Good, clear communication during the initial enquiry is a great sign. Finally, ask specifically about their warranty on both parts and labour, as this shows they stand behind their work.

The industry standard is a 12-month warranty covering the conversion work itself. This protects you against issues with the craftsmanship and installation of all fitted components. Individual appliances like fridges or [diesel heaters](/buying-guides/diesel-heaters) will be covered by their own manufacturer's warranties, which are often longer. Always get the warranty details in writing as part of your build contract.
