How Much Does a Campervan Conversion Cost in 2026?
If you're thinking about converting a van into a campervan, one of the first questions you'll have is: how much is it actually going to cost? The honest answer is that it depends on the van, the spec, and how far you want to take it — but we'll break it all down here so you know what to expect.
At Street Vanz Campers in Chesterfield, we've been doing conversions for years across a range of vans including the VW Transporter, Ford Transit Custom, Mercedes Vito, and Vauxhall Vivaro. Here's a realistic look at what you'll spend in 2026.
The Base Van: Your Biggest Single Cost
Before any conversion work begins, you need a van. A decent used VW Transporter T5 or T6 will set you back anywhere from £8,000 to £20,000 depending on age, mileage, and condition. Ford Transit Customs tend to be a bit cheaper, starting around £6,000 for older models. If you already own a van, you're already ahead of the game.
What Does the Conversion Itself Cost?
This is where the range gets wide. A basic day-van conversion with insulation, ply lining, a simple bed, and some 12V electrics might start from around £3,000 to £5,000. A mid-range conversion — with a proper kitchen unit, leisure battery system, LED lighting, and custom upholstery — typically lands between £8,000 and £15,000. A full high-spec build with lithium batteries, solar panels, diesel heater, hot water, and bespoke cabinetry can push past £20,000.
At Street Vanz, we work with you to match the build to your budget. Whether you want a weekend getaway van or a full-time home on wheels, we'll give you an honest quote before any work starts.
Electrics, Heating, and Plumbing
Electrics are one of the most underestimated costs. A basic leisure battery setup with a split charge relay might cost around £300 to £500 installed. Upgrading to a lithium battery system with a proper battery management system, inverter, and solar panel will cost closer to £1,500 to £3,000. Diesel heaters typically add £500 to £1,000, and a basic plumbing setup with a hand pump sink runs from £200 to £500.
The Bed System Makes a Bigger Difference Than You Think
Your bed is the single piece of furniture you'll use every night, so it's worth getting right. Many converters use a standard rock and roll bed, but at Street Vanz we've developed our own Trident Bed System. It offers three separate configurations in one unit — a flat double bed, two singles, or a sofa — without any of the awkward gaps or uncomfortable sleeping angles that plague cheaper alternatives. It's one of the things our customers rave about most.
So What's the Total?
For a realistic all-in budget including the base van and a solid mid-range conversion, you're looking at somewhere between £15,000 and £30,000 in 2026. That's a lot less than buying a brand-new factory campervan, which can easily cost £50,000 to £70,000 — and you'll end up with something that's built exactly the way you want it.
