How Much Does a Campervan Conversion Cost?

19 December 2022 | Last updated 3 November 2025

In this article, we’ll walk you through all the costs of converting a van into a campervan – from the inital van purchase and must-have fittings to reliable insurance that will keep your home on wheels protected, so you can plan with confidence.

What is the cost of a campervan conversion? This is the question everyone asks when they think of taking off into the sunset in the campervan of their dreams. It’s a difficult question to answer, as cost is affected by so many factors, from vehicle dimensions, finish quality, and the size of your budget.

It’s possible to spend as little as a few hundred pounds on a basic campervan conversion if you use second-hand materials and do the work yourself. Alternatively, a full, luxury camper conversion performed by professional fitters involving brand new materials and top-of-the-range products can run into tens of thousands of pounds.

While a camper van conversion varies between relatively cheap to extravagantly expensive, we’ve broken down the estimated costs according to the work that’s typically carried out. So, before you hit the open road, here’s what you are likely to pay for a typical campervan conversion.

What is the Cost of Converting a Campervan?

Campervan Costs

Estimate: £1,000 – £15,000

Whether you are converting a regular van into a campervan or modernising an older Volkswagen camper for example, purchasing the vehicle is likely to be your biggest expense before any conversion work has even started.

A shiny, new campervan is a nice thought but is probably beyond most people’s budgets, so buying a used campervan is a popular choice. You’ll have more money left over to spend on the vehicle by undertaking conversion work yourself than you would if outsourcing to a specialist garage, which is something else to consider.

While we always encourage people to get stuck in and work on their own campers and vehicles, we also urge that if you don’t have the tools, experience or confidence to tackle a job yourself, you look for a professional who can do it for you.

The type of second-hand campervan you buy depends on your personal requirements and, most of all, the size of your budget. At the lower end of the price range are mini campervans such as the Volkswagen Caddy and Renault Kangoo. It’s a tight squeeze for two people with limited storage, but fitting in a small kitchen and toilet is possible.

Small campervans like the Volkswagen Caddy Maxi, Citroën Berlingo or Toyota Tarago are roomier, can comfortably sleep two and almost certainly include a toilet space and a kitchen area.

Used mid-sized campervans can sleep up to four people and should include a fixed bed, kitchen, bathroom area and storage units. Volkswagen T25 Transporters and Kombis, the Ford Transit, and short wheelbase Toyota HiAce are great options for a mid-sized campervan.

Large campervans like the long-wheelbase Volkswagen T6, Ford Econovan, Renault Traffic, Vauxhall Vivaro and long-wheelbase Toyota HiAce will almost certainly contain fixed bedding and seating, a toilet/bathroom space, kitchen and storage.

Full-size campervans sit at the top of a budget and can sleep up to six people. Fixed beds and seating, a kitchen, bathroom and ample storage come as standard. The Volkswagen Crafter, Mercedes-Benz Sprinter, Iveco Daily and Renault Master are typical examples of this category.

Insulation Costs

Estimate: £300

It’s absolutely essential to insulate the inside of your campervan to keep out the cold and avoid problems with damp. Materials such as a thermal insulation board, wool and aluminium tape are relatively cheap and will keep you warm and snug even in winter months. If fitted by a conversion company, there will be added labour costs to consider.

Our sister company, Just Kampers, stocks a range of insulation options for your camper conversion, and if you insure with Just Kampers Insurance you’ll get 10% off orders for the duration of your policy.

Window Costs

Estimate: £1,000

A conversion company will charge between £200-300 per window and a similar amount for a roof vent plus labour costs. If you do the work yourself, however, you can expect to pay between £500-600 for windows and a jigsaw to cut them out.

It’s not as difficult as it seems to install windows into your camper yourself, and we’ve got a how-to video on the process which you can watch here.

Just Kampers also stocks an exclusive range of JK Glass windows, with Just Kampers Insurance customers getting 10% off.

Flooring and Lining Costs

Estimate: £750

The price of flooring and lining vary wildly depending on the materials used. A new and fitted plywood floor can cost £500 alone and lined walls around £250. Using recycled materials and fitting them yourself will bring down costs.

Interior Fitting Costs

Estimate: £600 – £5,000

You can be as basic or lavish as you want here. Using a simple design, recycled materials and doing the work yourself will save money. On the other hand, incorporating a kitchen, sink, fixed beds and seating fitted by conversion experts will be much more expensive.

While some of these appliances can seem pricey, if you’ve got vehicle insurance with us here at Just Kampers Insurance, you’ll save 10% on orders from Just Kampers, which can make a huge difference!

Electrical System Costs

Estimate: £1,000

This is best left to the professionals unless you’re a qualified electrician. You can expect to pay around £1,000 for a full 12v wiring system for battery, split charger and lighting.

If you do have the skills, training, and equipment needed to take on the work yourself, a basic 12v system (battery, connections and cables) ranges from approximately £200-£400.

An inverter that converts a 12v battery into a 240v mains is around £150-£270 and solar panels around £300.

Kitchen Costs

Estimate: £200 – £1,100

There are a wide range of costs involved with kitchen conversions, and you can pay as little or as much as your budget allows. An electric cool box is £30-£90, a 12v fridge starts at around £200, a compressor fridge-freezer can often be around £700, and a gas hob burner may be anything from £30 to £300. You will also need to budget for other kitchen items such as a kettle and crockery.

Water Tank Costs

Estimate: £200

A conversion company will charge around £200 for a 70L water tank, pump, pipes, connectors and plumbing, and more for a shower which will require a boiler or solar heating. It is possible to buy your own materials and do the work yourself but with minimal cost savings.

Toilet and Shower Costs

Estimate: £320

A cassette toilet is perfect for campervan conversions and costs as little as £60 to buy including chemicals. A conversion company will charge around £150 for a fully fitted toilet.

A tankless, LPG water heater shower costs around £170 before installation.

Gas and Heating Costs

Estimate: £1,000 – £1,500

The UK can be chilly at night even in summer months, so a reliable and efficient heating system is essential. A gas connection for cooking and hot water will cost between £500 – £800 when fitted by a qualified professional. A gas tank, heater and pipes should cost a similar amount.

Safety Costs

Estimate: £80 – £500

It is important to ensure your beautifully converted campervan is safe and fully secure.

We recommend budgeting for some of the following items: alarm (£300), wheel clamp (£50), steering wheel lock (£60), immobiliser (£30), smoke/carbon monoxide alarm (£30) and GPS tracker (£75) at minimum.

Insuring Your Converted Campervan

The price of insuring your campervan is determined by a number of factors such as the vehicle’s size, age, make and value, as well as its internal features. Insurance premiums will be higher if more than one person is named as a designated driver.

Driving history is another consideration, as premiums are likely to be more expensive if you have recently caused an accident.

Storage and security will also affect the cost of your policy. It’s cheaper to insure your campervan if it is kept in a locked garage at home as opposed to parking it on a driveway or in the street.

However, don’t be put off by the cost of insurance. Here at Just Kampers Insurance, we offer self-build campervan cover from as little as £225 a year!

We’ve been providing affordable insurance for campervans since 1998, and are trusted by thousands. Get a quick online quote now.

Hire Out Your Converted Campervan

Instead of your converted campervan sitting idle on your driveway when it isn’t being used, why not hire it out so that it becomes a source of income? It’s possible to charge between £70 and £95 for an average day’s rental of your vehicle and there are a number of companies who will help you do this, though you will have to pay extra for insurance.

Summary

So, converting a van into a campervan isn’t the cheapest project in the world, but it’s far more flexible than you might have first thought.

The overall cost of the conversion all depends on the choices you make, from the type of van to the materials and appliances you choose. By using budget-friendly materials, buying a second-hand van, and carrying out a lot of the work yourself, you can significantly cut costs without sacrificing results.

And with the right insurance policy, you can keep your home on wheels protected without breaking the bank (and save money on parts at the same time!)
