How Much Does It Cost to Build a Campervan?
A Practical Budget Guide
Find The Right Van To Convert
Our first campervan was a budget-built Renault Trafic. We wanted a comfortable place to sleep, a simple kitchen and enough storage to get going. Later, we built a larger van with a better bed, and eventually another with a proper kitchen and somewhere to sit down for dinner. Each build gave us more comfort, but it also helped us understand which things were worth spending money on.
That is where we would start with your budget too: what do you need the van to do, and what can wait until you have travelled in it?
For an initial UK budget, we would allow around £2,000–£5,000 for materials and equipment in a simple DIY campervan conversion, £5,000–£12,000 for a more complete holiday build, and £12,000 – £25,000 or more for an extensive conversion. These estimates exclude the van, vehicle repairs, paid labour and money set aside for unexpected costs. A basic camping setup can cost less, especially if you already have suitable equipment.
These are broad planning estimates, not an industry average or the bills from our own builds. We are Jacob and Amanda, the Swedish couple behind CamperPals, and this guide brings together what we have learnt from three conversions and travelling in Europe. The worked example uses pounds and a UK buying context. If you are building elsewhere, use the same method with local prices; changing the currency alone will not account for differences in vehicles, labour and taxes.
By the end, you should be able to put together a first budget, see which choices will change it most and decide how much you can spend on the van itself. till och hur du sätter en budget som lämnar utrymme för att också använda bilen.

Start with the cost of the whole project
When you read that someone built a campervan for £4,000, check what that amount includes. It might cover the interior of a van they already owned, with tools borrowed from a friend. Another builder may include the vehicle, repairs and professional help. The figures can both be honest while describing very different projects.
For your own budget, keep five things separate: buying the van, getting it mechanically ready, buying the conversion materials and equipment, paying for help, and keeping some money for unexpected costs. Insurance, vehicle tax, parking and your first trip also need a place in the overall plan, even though they are not part of building the interior.
Work out what the conversion needs before deciding how much you can spend on the base vehicle. If all the money goes into buying the van, even a modest interior can become difficult to finish. A slightly less expensive vehicle may leave room for the bed, electrical system and repairs that make it useful, provided its condition is suitable.
That last part matters. A cheap van with serious rust or overdue repairs can absorb the money you had set aside for the conversion. Check its condition and service history, and consider an independent inspection before buying. On commercial vehicle adverts, also check whether VAT is included in the advertised price.
We would choose the size from the layout you actually need, then compare suitable vehicles within the money left. Our guide to choosing a van for a campervan conversion looks more closely at that decision.
What different campervan budgets can cover
There is no fixed price for a “proper” campervan. A simple build can work very well for summer weekends, while a van used for longer trips may need a more comfortable indoor space, reliable refrigeration and more storage. The useful comparison is between the journeys each build supports.
| DIY conversion level | Illustrative UK materials and equipment budget | What you might plan for | Main compromise |
|---|---|---|---|
| Simple weekend build | £2,000 – £5,000 | Bed, basic storage, modest interior finish, simple water and cooking arrangements, limited electrics | More reliance on campsite facilities, outdoor living or short trips |
| More complete holiday build | £5,000 – £12,000 | Better furniture and mattress, compressor fridge or coolbox, roof ventilation, more capable electrics and a usable kitchen | Choosing carefully between extras such as heating, additional windows and hot water |
| Extensive conversion | £12,000 – £25,000+ | More built-in equipment, larger electrical system, improved indoor comfort and potentially a shower or more elaborate furniture | Higher cost, more installation work, greater weight and more systems to maintain |
These bands cover materials and equipment for work you largely do yourself. The vehicle, repairs, paid work and reserves are additional. They are starting points for planning, not promises that every feature will fit inside each range. The detailed example later shows how to turn a broad figure into a more useful shopping and work list.
Our own builds followed changing needs. The first, a 2015 Renault Trafic converted in 2017, was a simple stealth camper to help us get started with vanlife. Our second was a 2018 Nissan NV400, with more space and a better, more comfortable bed. The third, a 2021 Citroën Jumper, was built for our longest trip, with a proper kitchen, dining space, better storage and large windows.
The point is not that everyone should work towards a larger build. We made different choices because we wanted different things from the vans. For a first conversion, being able to describe an ordinary day on your trip is more useful than collecting a long list of equipment. Think about sleeping, cooking, getting dressed and where you will sit if it rains all evening.
Where the conversion money goes
The large purchases are easy to remember. A fridge, a mattress or a battery has a visible price. What is less obvious is everything needed to fit it properly and make it work with the rest of the van. Looking at each part as a complete job will give you a more realistic budget.
Insulation, flooring and furniture
With insulation, start by estimating the surfaces you want to cover and the material suitable for them. Then include tape, adhesive and the details around doors, ribs and awkward corners. The floor, wall lining and ceiling are separate purchases, so a price for insulation alone will not tell you what it costs to finish the inside of the van.
Furniture follows the same pattern. Plywood is only part of a bed or kitchen unit: you may also need supports, hinges, drawer runners, catches, edging and a finish. A more complicated layout creates more joints, doors and fittings, as well as more opportunities to cut something twice.
For a modest build, we would give a comfortable mattress and practical storage priority over an expensive finish. You use them every day. Reusing suitable materials can save money, but check their condition, weight and how you will secure them in a moving vehicle. A household cupboard that happens to fit is not automatically a good van cupboard.
If you are still deciding what belongs behind the walls, our campervan insulation guide explains the options. Make those choices before costing the finished panels, because each layer takes up some of the space you are trying to use.
The electrical system
Start with what you want to power. Lights and phone charging make different demands from a fridge, laptops and electric cooking. Write down the appliances, roughly how long you will use them and how you expect to recharge when travelling or parked.
A leisure battery stores energy for the living area. It is one part of a system that may also need charging equipment, fuses, cable, switches, distribution and secure mounting. An inverter adds household-style AC power from the battery, but it also needs to be sized and installed for the appliances it will supply. Buying one before deciding what you actually need can make the system more expensive than necessary.
This is a good place to compare complete proposals. A battery that looks affordable on its own may need a different charger or other changes to work in your setup. Likewise, a kit may leave out vehicle-specific fittings or cable lengths. Ask what is included and what still needs to be bought, and allow for specialist design or installation help where needed.
We would settle the fridge and cooking choices before buying the electrical equipment. If you later switch to electric cooking, you may be changing much more than the hob. Our campervan electrical system guide is the next step when you are ready to put the appliances, battery and charging together.
Ventilation and heating
A roof fan has a purchase price, but fitting it may also involve a suitable adapter, sealant, wiring and an interior frame. Paid installation adds another cost. Plan the roof as a whole so that the fan, any solar panels and other openings have room without forcing an expensive change later.
It is important to compare different products and brands; the MaxxFan Deluxe (40×40 cm) costs around 359 £. It is a popular and well-known roof fan found on many campervans today. Another popular model is F36AR, it’s a cheaper option costing approximately 144 £. So, before making a purchase, check out the available alternatives and their reviews.
With heating, ask for the cost of a complete installation in your particular van. The heater itself is only one part of the job. Mounting, fuel supply, combustion air, exhaust routing and commissioning need to follow the manufacturer’s requirements and the rules that apply where the van is registered.
Whether heating belongs in the first build depends on your trips. For summer weekends, you may choose to leave it out initially. For regular cold-weather travel, it deserves a place in the budget from the start. Insulation and ventilation still need their own consideration; adding a heater does not settle those decisions.
If you plan to cook and spend plenty of time inside, we would compare roof fans with that daily use in mind. Check the roof opening, available height, power requirements and fitting parts before choosing a model. A simpler roof vent may be enough for a more basic setup, depending on the ventilation the van needs.
Kitchen, fridge, water and toilet
A simple kitchen with a worktop, storage and water containers can cover a surprising amount of everyday life. Fixed tanks, pressurised water, hot water and a shower add convenience, but they also need more space and more parts. It helps to decide how you want to cook and wash before choosing the individual products.
A kitchen you can actually use
When planning the kitchen budget, include somewhere to prepare food and put down a hot pan, as well as the cooking appliance itself. A larger hob is not much help if it takes away all the worktop. Think through where the plates, food and washing-up will go while someone is cooking.
Simple cooking equipment can keep the initial cost down, particularly when you are happy to cook outdoors. Use appliances only in the locations and conditions approved by their manufacturer. A built-in gas installation needs its own fitting and safety budget; electric cooking needs an electrical system capable of supplying it. Compare the complete arrangements before deciding which is cheaper for your van.
Our Jumper had a proper kitchen and two roof fans, but cooking smells still found their way into the walls and bedding. Jacob is still not allowed to cook bacon inside. It is a small detail, but a useful one when imagining daily life in the van: even a more complete kitchen comes with compromises, and you may still want an outdoor cooking option.
Why the fridge deserves a closer look
A fridge affects the budget twice: when you buy it and when you plan the electrical system that will keep it running. That is why we would look beyond the price on the box.
To give the purchase difference some context, UK listings checked in September 2026 included a 30 litre Euhomy compressor coolbox at about £210 and a 35-litre Dometic CFF5 at about £505. A simpler 28 litre AEG thermoelectric coolbox was about £110. These are individual price examples, not a complete market range or products we are claiming to have tested.
The cooling technology matters as much as the size. Compressor models can offer a selectable fridge temperature, while thermoelectric models commonly describe cooling in relation to the surrounding temperature.
If your budget allows it, you enjoy cooking and you expect to spend several days away from campsite electricity, we would prioritise a suitable compressor fridge or coolbox. The higher purchase price can be worthwhile for dependable temperature control and an electrical setup planned around its daily energy use. For occasional trips with access to power, a cheaper coolbox may meet your needs, provided its cooling performance suits the conditions.
We would not assume that every compressor coolbox uses a fixed fraction of the electricity of every thermoelectric model. Compare daily consumption under similar conditions where the manufacturer provides it. The wattage printed on an appliance tells you about power use at a particular operating point; it does not, on its own, tell you what the appliance will use over a whole day. Temperature, settings and how it runs all matter.
Before buying, also check that the lid or door will open in your layout, that the unit can be secured, and that it has the ventilation the manufacturer requires. Noise is worth checking for the particular model too, especially if it will sit beside your bed.
Water: containers, a foot pump or a fixed system?
Water containers and a simple pump can be a sensible place to begin. They let you carry fresh water and collect waste water without immediately committing to fixed tanks, a pressurised system or hot water. In our Nissan NV400, we used a foot pump for the kitchen tap. It was part of a simple kitchen in a larger, more comfortable van; extra space did not mean every system had to become more complicated.
A fixed tank can be convenient, particularly on longer trips, but include the filler, plumbing, fittings, supports and access for cleaning or maintenance. A shower adds more than a shower head. You also need somewhere to stand, a way to contain and drain the water, and enough fresh-water and waste-water capacity for how you will use it. Hot water adds another decision about equipment and its energy supply.
If you mainly use campsite showers and need water for cooking and washing up, we would price a simple arrangement first. If you expect to wash inside regularly, cost the whole system and the space it takes before finalising the layout.
A toilet does not have to mean a bathroom
A portable toilet can give you an indoor option without building a separate room. You still need a secure place to carry it, enough space to use it and a practical way to empty and clean it. Consider privacy too, particularly when more than one person is travelling.
A separate bathroom brings additional walls, doors and fittings, and a combined shower room needs waterproofing and drainage. That can change the whole layout. Other toilet types also have different purchase costs, installation needs and waste-handling routines, so compare the daily use as well as the product price.
For a first build, decide whether you need a toilet for occasional use or want a bathroom you will use every day. It is an easier way to choose a budget than starting with the most complete system and trying to find room for it afterwards. If you would like to try a portable toilet, we would recommend Porta Potty
Maybe you feel like you would need something simplier, budget friendly and compact. Then this foldable potty is to recommend.
A worked DIY campervan budget
Here is an example for two people who want a comfortable bed, usable kitchen, compressor coolbox, roof fan and heating. Most work is DIY, with some money included for paid help and checks. There is no indoor shower, hot water, pop-top roof, additional travel seating or large electrical system for electric cooking.
The figures below are our illustrative UK planning amounts, including VAT where applicable. They are not a priced kit, a professional quote or our own spending record. Replace each line with the products, quantities and quotes for your build before committing to the total.
| Item | Example budget |
|---|---|
| Insulation, tape and adhesive | £450 |
| Floor, wall and ceiling materials | £650 |
| Bed, mattress, storage and furniture fittings | £1,200 |
| Battery, charging, cable, fuses and lighting | £1,600 |
| Roof fan and fitting materials | £500 |
| Compressor coolbox | £450 |
| Basic kitchen and cooking equipment, excluding furniture above | £300 |
| Water containers, sink and simple pump | £200 |
| Basic portable toilet | £100 |
| Heater and fitting materials | £900 |
| Tools, consumables, small purchases and delivery | £400 |
| Paid help and checks | £750 |
| Planned conversion spending | £7,500 |
| Money for unexpected conversion costs: 15% in this example | £1,125 |
| Conversion budget including that reserve | £8,625 |
The £7,500 consists of £6,750 for equipment, materials and tools, plus £750 for paid work. The 15% is a planning choice for this example, not a guarantee that it will cover every surprise. An uncertain design or a build needing more professional work may need a larger amount.
Now add the vehicle. If you set aside £12,000 to buy a van, £1,500 for initial servicing and repairs, and a separate £1,500 vehicle repair reserve, the total becomes £23,625, including the £8,625 conversion budget. The vehicle figure is a hypothetical allowance, not a claim about what a particular model currently costs. You would still need to account for insurance, vehicle tax, parking, any workshop rent and the first trip. Keeping the vehicle reserve separate helps you see whether the interior is affordable without spending the money you may need to keep the van on the road.
Use this table as the beginning of your own list. Add a column for what you have already bought and another for what remains. For large purchases, write down what the price includes. That makes it much easier to spot missing installation parts and avoid counting the same furniture or equipment twice.
Does a campervan for four or five people cost much more?
The cost does not rise evenly with each extra person. Two people may share one kitchen, fridge and electrical system, and a family can share those too. The bigger changes often come from the layout, suitable travel seating, sleeping arrangements and the weight the vehicle can carry.
Before buying a van for four or five people, establish how everyone will travel safely and what seating arrangements are permitted for that vehicle in your country. A bed or dining bench is not automatically a suitable travel seat. Adding seats and belt anchorages can be a substantial specialist job, so obtain advice and quotes before assuming it will fit the budget.
More people also means more luggage and usually more water, food and sleeping space. All of that uses payload, which is the weight the vehicle can carry within its permitted limits. A layout that looks spacious while empty may leave too little capacity once everyone and their belongings are aboard.
For two people, the main choice is often between a smaller van that is easy to use day to day and a larger one with more indoor comfort. For a family, suitable seats and beds need to work together from the start. Compare the layouts before applying a two-person budget to a bigger group.
The costs that are easy to miss
Tools, delivery and small fittings rarely feel like major purchases individually. Together, they can change the budget noticeably. Include blades, drill bits, sanding materials, sealant, fasteners and anything you need to borrow, hire or buy to finish the work. Ordering several missing parts separately can also add delivery charges that were absent from the original list.
Allow for mistakes and changes as well. A wrongly cut panel costs money, but changing the layout after fitting the electrics or water can cost considerably more. Trying the bed size and walking space before building the furniture is a simple way to find problems while changes are still cheap.
DVLA, paperwork and insurance
DIY does not mean you must do every job yourself. Ask early about work you may need help with, particularly electrical, gas, heating, structural or seating changes. Explain the intended setup and ask what design input, installation and checks the quote includes. The requirements depend on the work and where the van is registered.
Speak to your insurer about the conversion before beginning. Ask about cover during the build, the completed layout and any documents they will need. This belongs in the planning stage, while you can still change a decision without removing finished furniture.
For a UK example, DVLA’s body-type description is about the vehicle’s appearance and identification; it is not a blanket approval of the conversion’s safety. Its guidance also explains the circumstances in which a vehicle can be used as a motor caravan without changing that description. Read the official DVLA conversion guidance alongside the requirements that apply to your actual modifications. Elsewhere in Europe, check with the relevant authority and insurer in the country of registration.
Your time and somewhere to build
Even when you do not pay yourself for the work, the time still affects the project. A van that occupies a rented workspace for several extra months costs more, and a delayed build can change your travel plans. If you need the vehicle for work or everyday transport, consider how you will manage while it is unfinished.
We would leave some space in both the calendar and the budget. Buying every component before the layout is settled can tie up money in things you later change, while a very tight deadline can leave you paying for help simply to get the van ready.
Where we would save money on a first build
We would begin with a sound vehicle, a comfortable bed and a layout that makes everyday tasks easy. Then we would choose the electrical, water and cooking arrangements needed for the first trips. Decorative finishes and equipment for journeys you might take years from now can wait. There is a difference between postponing an upgrade and making it difficult to add later. If you expect to improve the van, think about access to wiring, plumbing and fixings while they are still visible. You do not need to buy every future appliance, but you can avoid sealing important parts behind furniture that must be destroyed to reach them.
Second-hand materials and equipment can help when their condition and suitability can be checked. We would be more cautious with components whose history or compatibility affects safety. Saving on a cupboard finish is a different decision from guessing whether an electrical component is suitable.
We would also avoid buying too much equipment just because it appears in other conversions. A smaller system that meets your needs leaves money for travelling. After a few trips, you will have a much clearer idea of which inconvenience you want to solve next. Our own vans have continued to change as we have used them; the first version does not have to answer every future need.
Is it cheaper to build, buy or rent a campervan?
Building can make financial sense when you have the time and skills, do much of the work yourself and want a fairly simple layout. It also lets you put the money into things that matter to you. But a DIY conversion is not automatically cheaper than a comparable finished van, especially if the base vehicle needs work or you end up replacing several early decisions.
When comparing a ready-built campervan, look at its condition, layout and installation quality as well as the asking price. For a professional conversion, ask for a written quote that makes the scope clear: vehicle included or supplied separately, equipment, materials, labour, taxes, checks, warranty and any unfinished work. A low starting price is difficult to compare with a complete build until you know what each contains.
Renting is worth considering when you only want a few trips or are unsure what kind of van suits you. We have also rented campervans for a week at a time on trips farther away, when driving our own van did not feel worthwhile. It has been a useful way to get inspiration for changes too.
A rental trip gives you a chance to try the bed, kitchen and indoor space before committing to your own layout. Include the rental cost in your decision, of course, and compare deposits, mileage, insurance excess and equipment rather than just the daily rate. If the experience helps you avoid building something you do not enjoy using, it can be money well spent.
A few more budget questions
You may be able to put together a very simple camping setup for £1,000 if you already own a suitable van and reuse a mattress, storage and camping equipment. It is a different scope from a fitted conversion with permanent electrics, heating and a finished interior. Write down what that amount must cover, including secure fitting, before deciding whether it is enough.
It can be enough for a modest conversion when the vehicle is already paid for, most work is DIY and the equipment choices stay simple. If £5,000 is your absolute limit, keep part of it for unexpected costs rather than planning £5,000 of purchases. Paid help, vehicle repairs or a more demanding electrical system can change what is possible considerably.
A professional build needs a quote for a defined layout and vehicle. Our DIY ranges do not include the labour needed for a full professional conversion, and adding a standard percentage would give a misleading answer. Send the same requirements to the converters you are considering so that their prices can be compared fairly.
Allow for insurance, tax, servicing, repairs, parking or storage, and any inspections required where it is registered. Travel then adds fuel, campsites, tolls, ferries and other trip costs. These depend too much on the vehicle and your journeys for one annual figure to be useful, but they should be affordable alongside the build. Do not assume that selling the van will recover every pound spent on it.
Make a budget that leaves room to travel
A useful first budget tells you what the van needs, what each complete job is likely to cost and how much money remains when something changes. It should also leave you with a campervan you can afford to use.
Start with the trips you want to take, put the essential parts into the example budget and ask for prices on the work you will not do yourself. Then revisit the vehicle allowance. If the total is too high, simplify the layout or postpone an extra before using up the money set aside for repairs.
Once the budget feels realistic, our step-by-step guide to building a campervan will help you put the jobs in order. You can keep improving the van as you travel. A comfortable first trip is already a very good reason to build one..
