Citroen Relay Campervan Conversion Kits

Converting a Citroen Relay gives you one of the most spacious and versatile large panel van platforms on the road. A well-planned Citroen Relay campervan conversion kits setup allows you to convert your vehicle into a fully functional campervan without second-guessing compatibility or installation requirements. This guide is current as of the publication date, helping you make informed decisions throughout your conversion journey.

Our Citroen Relay campervan conversion kits are designed specifically for the Citroen Relay, as well as equivalent vehicles, which share a similar base vehicle platform. These kits help DIY builders and professionals alike to simplify the conversion, ensuring every kit component works together. Whether you're building a weekend camper van or preparing for off grid travel, these kits provide a complete solution.

Making the right decisions in your conversion often involves balancing space, layout, and comfort. The Citroen Relay campervan conversion is a popular choice thanks to its wide body, allowing transverse bed setups and a more spacious interior than many other vehicles like the transit. This extra width is a key point for maximising storage and living space.

Your Citroën Relay Planning Checklist

1. Define Your Use Case

How many people will be travelling, whether it’s part-time or full-time, if pets or remote work are involved, and the type of trips you plan with your Citroën Relay.

2. Set Budget & Time

Total cost (vehicle + build) and how long you can realistically commit to completing your Citroën Relay campervan conversion.

3. Choose the Right Relay

Decide on the right Citroën Relay or equivalent platform such as Fiat Ducato or Peugeot Boxer, including wheelbase, roof height, payload, and condition.

4. Plan for Weight

Ensure your Relay, water systems, batteries, storage, and passengers remain within legal vehicle weight limits.

5. Decide Your Layout

Bed orientation (widthways or lengthways), fixed vs convertible bed, kitchen size, and storage configuration to maximise interior space.

6. Bathroom Strategy

No bathroom, compact shower/toilet setup, or full installation — this will significantly impact layout, cost, and complexity.

7. Electrical System Level

Basic lighting and fridge setup or a full off-grid electrical system depending on your needs.

8. Water System Size

Tank capacity, hot water setup, and how long you plan to stay off-grid between refills.

9. Heating & Gas

Diesel heater, LPG system, or electric heating depending on your travel style and climate.

10. Insulation & Ventilation

Insulation type, vapour barrier, and roof ventilation to control temperature and condensation.

11. Interior Finish Standard

Choose between a practical finish or a more premium build depending on budget and desired comfort.

12. Legal & Insurance

Vehicle classification, insurance requirements, payload compliance, and certification for gas and electrical systems.
