Campervan Modifications and Conversions

There’s something deeply satisfying about personalising a campervan. Whether it’s a full self-build or a few clever tweaks to an existing layout, modifications let you tailor your vehicle to your lifestyle. But before you get carried away with wood panelling and fairy lights, let’s talk about the practical side - because modifications can have serious consequences, especially when it comes to legality, safety and insurance.

What Counts as a Modification?

That’s the thing, pretty much anything that changes your campervan from its original factory spec. Some changes are cosmetic, others are structural or mechanical. And yes, insurers care about all of them.

  • Engine remaps or suspension upgrades
  • Adding windows or roof vents
  • Fitting a rock-and-roll bed
  • Solar panels or leisure batteries
  • Gas hobs, water systems or heating installs

Even a pop-top roof or reversing camera can fall under the “modification” label. So it is worth checking if your insurer needs to know, and spoiler alert, they usually do.

Just Imagine...

A chap once converted a panel van into a camper, fitted a gorgeous kitchen, lovely upholstery, even a solar setup. But he forgot to tell the insurer. Three months later, a minor crash resulted in a write-off; and the insurer refused to pay out. Why? Because the van on paper no longer matched the van in reality. Painful mistake.

A family sat enjoying a peaceful morning outside their motorhome, confident they are covered for any surprises.
Wherever we park up, we know we’re protected.

DVLA and Campervan Conversions

If you’re doing a full conversion, you might want to get the DVLA to reclassify your van as a “motor caravan”. This can have implications for insurance, MOT, and speed limits. But getting reclassified isn’t as easy as sticking in a bed and painting the cupboards duck egg blue.

To be recognised as a motor caravan, you’ll need:

  • A fixed bed or seating that converts
  • Fixed table (can be removable, but must have a mount)
  • Permanent cooking facilities
  • Storage for food and clothes
  • Windows on at least one side

Plus, it needs to look like a camper from the outside. That means things like graphics, an awning rail, maybe even a side window sticker. DVLA are picky about this, it’s not just about what’s inside.

Safety First: Are Your Modifications Compliant?

Gas installations must be safe. Electricals must be fused and isolated correctly. If you’re not a qualified electrician or Gas Safe engineer, it is smart to get the work checked, or at least inspected; by someone who is.

Some insurance policies require proof that installations meet certain standards (especially gas). Without that? A claim might not go your way.

Does Every Change Affect Insurance?

Not always. Swapping curtains or installing new flooring probably won’t raise eyebrows. But here’s a rule of thumb: if it affects the value, structure, or safety of the van, or how it’s used; mention it.

Professional Vs DIY Conversions

Both have pros and cons. Professional jobs usually come with receipts, warranties and certificates. DIY conversions give you creative freedom, but can be trickier to insure if corners are cut or safety standards aren’t met.

Whichever route you take, document the process. Take photos. Keep receipts. Write a list of materials and parts used. If the van is ever written off or stolen, this all helps justify the valuation.

Insurance Tips for Modified Campervans

  • Always declare modifications when getting quotes; even if they seem minor
  • Keep your insurer updated as your build progresses
  • Ask if modifications affect cover for breakdown, recovery, or personal possessions
  • If you’re part-way through a conversion, make sure it’s insured as a van-in-progress

A Final Word

Campervan conversions are exciting, creative and personal; but they come with responsibilities. Safety, legality and transparency are key. If something goes wrong, having everything properly documented and disclosed could be the difference between a smooth claim and a financial headache.

Planning a conversion or thinking about upgrades? It might be a smart move to get quotes first; modified campers can vary a lot in insurance cost. Better to know what you’re in for, before you cut that first hole in the roof.
