There is no single price for a campervan conversion. The total depends on the condition of the starting van, the equipment you choose, the amount of work you do yourself and which jobs need a specialist.
The ranges below are useful starting points for a VW Transporter-sized van in 2026. They are not fixed packages. Two conversions at the same price can contain very different equipment, so compare the complete specification rather than the headline figure.
Budget DIY conversion: £3,000 to £8,000
This is the self-build route. You provide the time, tools and most of the labour, bringing in qualified help where the work is beyond your skills. The range is wide because a simple weekend van and a four-berth camper with a pop-top are very different projects. Before buying parts, decide what the van genuinely needs to do and leave room in the budget for mistakes or changes.
Mid-range conversion: £10,000 to £20,000
At this level, the owner may complete some straightforward work while a converter handles larger or safety-critical jobs. Another option is a simpler professional conversion with a shorter equipment list. The budget might cover insulation and lining, furniture, a tested travelling seat or bed, basic electrics, heating and selected exterior work, but the exact combination will vary.
Be clear about who is responsible for each stage. If several specialists are involved, make sure their work fits together and that you receive the relevant diagrams, manuals, invoices and test records.
Full professional conversion: £20,000 to £40,000
A full professional conversion is the handover-the-keys route. The converter manages the build and supplies a finished campervan to an agreed specification. You are paying for skilled labour, workshop facilities, project management, installation records, snagging support and warranty cover as well as the physical components.
Most converters begin with a standard package and offer a list of options. These may be published on their website or worked through during a design appointment. Use the same list of must-haves with several companies, then compare the itemised totals. Check what is included as standard, whether labour and VAT are included, and which choices are still provisional.
Location can influence the quote because workshop overheads and local demand vary. Prices in parts of northern England and Wales may be lower than comparable work in the South East or popular campervan areas such as Cornwall, although this is not a universal rule. A distant converter may look cheaper until you include travel and the practicalities of returning for snagging or warranty work.
Buying a recently converted van
A professionally converted van that is two or three years old can offer good value. You avoid the build wait and can inspect the finished layout before buying. The important word is provenance.
Ask who completed the conversion and request the original invoice, specification, installation records, manuals and warranty documents. Check the base vehicle's service history and look for evidence of later alterations. Age alone does not prove that every early fault has been found, so judge the van and conversion on their present condition.
Compare VAT-inclusive totals
Confirm whether VAT is included in every figure you are given. A quote that looks cheaper before VAT can become more expensive than an inclusive alternative once the totals are compared. Ask how long the written quote remains valid and how any later specification changes will be approved and charged.
Weight and payload
Volkswagen's T28, T30 and T32 labels refer to gross vehicle weight classes of roughly 2.8, 3.0 and 3.2 tonnes. The codes have been used across UK-market T5, T6 and T6.1 Transporters and continue on the current Transporter, although the precise limits vary slightly. Current models, for example, are listed at 2,800kg, 3,025kg and 3,225kg.
Those figures are not the payload. Payload is what remains after subtracting the van's actual unladen weight, so the conversion, passengers, fuel, water, luggage and accessories all reduce it. Higher-rated versions have greater permitted axle loads and running gear intended for more weight. Some may feel firmer when lightly loaded, but the ride also depends on the generation, specification and any suspension changes.
Ask the converter for the completed van's weight and individual axle weights, ideally supported by a weighbridge ticket. They should also provide a clear calculation showing how much usable payload remains.
Choose the route around your use
A simple van for occasional summer weekends does not need the same specification as one used for longer trips away from electric hook-up. Start with how many people will travel and sleep in it, when you expect to use it and which facilities matter every day. That will tell you more than choosing a budget tier first and trying to fill it.
Prices and lead times change, so obtain a current written quote before making a decision. A good quote should make the base specification, optional items, VAT, payment stages and expected completion date easy to understand.
