CAMPERVAN CONVERSION GUIDES
Planning a campervan conversion before you buy the parts
It is tempting to start a campervan conversion with the enjoyable purchases: a bed you can picture using, a neat kitchen unit, perhaps the roof you have wanted since your first trip away. The less photogenic decisions come first. How will you use the van? What can the vehicle carry? Where will the water, wiring and cooking equipment go? Which work needs specialist input? The answers shape the build long before the first cabinet is fitted.
This guide is a way to put those decisions in order. It will not choose a van or layout for you. A good conversion is a collection of choices that fit a particular vehicle and the people using it. The aim is to leave you with a brief you can take to a seller, a supplier, an installer or a campervan conversion course and get useful answers.
Start with the trips, not the furniture
Imagine three ordinary trips you expect to make. A quick weekend in the Peak District can ask something different of a van than a fortnight away, a family holiday or regular overnight stops while working. Write down how many people will travel and sleep in it, how you will cook, whether you expect to work inside, and how much outdoor kit comes along. Be honest about the weather. A layout that looks generous with the doors open on a sunny day can feel cramped when everybody is inside with wet coats.
Then ask what you want to do without moving anything. Can one person make a drink while another is in bed? Can you reach the clothes without unpacking the kitchen? Is there a safe place for muddy boots? Does the table work when all the travelling seats are occupied? These small questions expose the difference between a layout that photographs well and one you will enjoy using.
Make two lists: the things the van must do and the things you would merely like. The second list is useful, but it should not silently take the space or budget needed for the first. If you are converting your everyday vehicle, include how it needs to work between trips. If you expect to use sites with electric hook-up, record that. If you hope to spend time away from hook-up, describe what you would actually power and for how long. Those choices feed into the services plan later.
Choose a base van that suits the brief
There is no universally best vehicle to convert. A compact van may be easier to park and use day to day but demands stricter choices about sleeping and storage. A larger van offers room, while bringing its own questions about parking, height, weight, driving licence and running costs. Before falling for a particular example, check that the basic vehicle format can accommodate the people and equipment in your brief.
Inspect the condition of the vehicle independently of the proposed conversion. Corrosion, water ingress, previous repairs and mechanical faults do not disappear behind a new lining. A conversion often hides parts of the body, so a careful inspection at the outset is especially valuable. Set aside money for the vehicle itself and for the repairs or maintenance it may need. A cheap van that needs extensive bodywork can become an expensive starting point.
Check the vehicle’s documents, its permitted weights and the driving licence required for the finished vehicle. Plan for the weight of people, water, luggage and the conversion itself. Do not treat the empty van’s payload as a permanent allowance after the roof, furniture, batteries and tanks are in. Weighing the vehicle at sensible stages of the project can tell you more than a spreadsheet alone.
If you are considering a pop-top roof, additional seats or major body alterations, discuss the specific van with a competent specialist before purchase. Some decisions depend on the vehicle structure and on the equipment fitted. Ask your insurer what they will need to know during the build and after it is completed. Keep a record of the changes you make.
Draw the layout at real size
A sketch is a starting point; dimensions settle arguments. Measure the usable interior of the actual van, including wheel arches, door openings and the places where the body narrows. Draw the bed both as seating and as a bed. Mark where people will stand, where doors swing and how cabinets open. A simple floor mock-up with cardboard or masking tape can reveal a collision that a tidy drawing misses.
Think vertically as well. Where can a person sit without hitting a cupboard? What headroom is available with the roof down and up? Can you reach a shelf from outside the van? Can you get to a service connection without emptying every cupboard? Plan for movement around the van, not just for the footprint of each component.
Test your layout against the trip brief. If two people will cook together, is there room for that? If children will sleep in the van, how will bedtime work while adults are still awake? If you will carry bikes or climbing kit, where does it go while travelling and where will it be when the bed is made? Every answer uses space; the important thing is to spend it deliberately.
Plan the systems before closing the walls
The electrical, water and gas plans belong alongside the furniture plan. Even when a specialist will do the installation, you need to decide what you want each system to do and where equipment can be accessed later. A socket is only useful if it is reachable when the bed is in use. A tap and sink need a sensible route for water supply and waste. A gas appliance brings questions about the appliance, its location, ventilation, cylinder storage and professional work.
Start with a list of uses rather than a shopping list. For electricity, note the lights, charging, fridge and any other appliances you expect to use, when you will use them and whether you will rely on hook-up. For water, decide whether you need only a sink or a more involved arrangement, where clean and waste water will live, and how you will fill and empty them. If you want gas, explain what you need it for and whether there is a simpler arrangement for your style of travel.
Our guide to campervan electrics, water and gas planning takes those questions further. It is deliberately about planning, access and competent work rather than a wiring or gas-fitting recipe. That separation matters: understanding the decisions is valuable even when someone else designs, installs or checks a system.
Decide the build sequence
One task often blocks another. You cannot sensibly finish lining a wall before deciding what needs to pass behind it. Furniture dimensions depend on the actual interior after lining and flooring. Roof work affects the structure and the finish around it. The exact order varies with the van, but your plan should show dependencies before purchases start arriving.
Write a rough sequence for inspection and repairs, layout decisions, any roof or window work, the systems plan, insulation and lining, flooring, furniture, final connections, finishing and checks. Treat it as a working document. The value is in seeing what you need to settle before the next stage becomes difficult to undo.
Put a hold point before irreversible work. Cutting the body, fitting a roof or permanently closing a service run deserves a fresh check of measurements, component instructions and the specialist advice relevant to that vehicle. Take photographs of hidden runs and keep receipts, manuals and test records together. Future you, or a future owner, will appreciate knowing what went where.
Give the budget room to breathe
A single figure for “conversion cost” hides too much. Break your budget into the base vehicle, inspection and repairs, body and roof work, insulation and lining, furniture, electrical system, water system, cooking and heating, seating, professional services, tools and finishing. Make a separate allowance for things you do not yet know. The figure should also include travel, accommodation or time away from work if those are part of your plan.
Decide where you want to spend on durability and where a simpler choice will suit the way you travel. A component is not a bargain if it forces expensive changes elsewhere. Before ordering, check its real dimensions, mounting requirements, weight, access needs and compatibility with the rest of the build. A photograph and a product name rarely tell the whole story.
Keep the budget live. When one choice changes, update the weight, space, time and cost beside it. This stops a series of individually reasonable purchases from producing a van that is too heavy, too cramped or too far over budget.
Know which jobs need another pair of hands
Learning to build does not mean doing every task alone. Body structure, extra travelling seats, mains electrical work and LPG gas work deserve particular care. The right person depends on the job and on the vehicle. Ask about relevant competence and experience, what the work includes, how it will be tested and what paperwork you will receive. For gas work within the scope of gas safety law, check the engineer’s Gas Safe registration and the appropriate LPG competence.
It is possible to make better decisions about specialist work without carrying it out yourself. A good briefing tells an installer where you hope to put an appliance, how you will use it and which other parts of the layout may conflict. Ask for advice before cabinetry makes access difficult. Leave room to inspect, maintain and repair equipment later.
Be wary of a plan that depends on a future installer solving every conflict after the interior is finished. Their answer might require taking your new work apart. Bring them into the project at the planning stage, then confirm the final arrangement against the actual vehicle and equipment.
Treat ventilation and condensation as design questions
People breathe, cook, dry clothes and bring moisture in from the weather. A van also changes temperature quickly. Plan how air will move through the finished space and how you will use the van in cold or wet conditions. Insulation is part of the answer, but it is not a substitute for suitable ventilation. Appliances and systems can have their own ventilation requirements, which must be checked against their instructions and the finished layout.
Think about what is easy to wipe, dry and inspect. A beautiful surface may hide a problem if you cannot see or reach behind it. Consider how you will dry bedding, where wet shoes will sit and whether storage areas can breathe. These are mundane decisions that affect how pleasant the van feels after the novelty of the first trip wears off.
Check the paperwork before assuming the label will change
People often ask whether a converted van will be reclassified as a motor caravan. The DVLA guidance on converting a vehicle into a motor caravan distinguishes the ability to use a vehicle as a camper from the body type recorded on its V5C. Its decision on a body type change depends on the vehicle’s existing record and the permanent internal and external features of the completed conversion. A pop-top alone, for example, should not be treated as a guarantee of a V5C change.
Read the current DVLA guidance for your vehicle rather than designing from a forum checklist. Tell your insurer about the modifications and check how cover works while the van is being converted. Keep the documents that show what was fitted and checked. Registration, insurance, roadworthiness and safe construction are connected concerns, but they are not the same decision.
Build a brief you can show somebody else
Before ordering major parts, put your plan on a few pages. Include the base vehicle and its dimensions, your typical trips, the people travelling and sleeping, a measured layout, the appliances you expect to use, a rough systems plan, your budget and the work you will seek professional help with. Add your open questions. A brief does not need to look impressive; it needs to make your assumptions visible.
If someone else can read it and describe back the van you are trying to make, you are in a much stronger position. A supplier can tell you whether a component will fit. An installer can spot a conflict early. Steve can help you connect the individual decisions to the whole conversion rather than answer a string of isolated questions.
Learn the process before committing to your own van
The five-day course at Peak Campervan Training follows a van from preparation through roof and interior work to a fitted living space. Steve provides the training van, and the group is usually around four or five people. You can work through the sequence in a workshop before making the same choices on your own vehicle. Students also do hands-on work with electrics, plumbing and gas under Steve’s guidance. A local gas engineer will inspect and sign off the gas installation on the training van. If one of those subjects matters especially to you, ask which tasks are planned for your chosen week.
You can read the full course outline and check current dates. Bring your brief, your vehicle questions and the decisions you are struggling to make. Those are the starting points for a useful conversation.
