How to Insure a DIY Campervan Conversion in the UK
Insuring a self-converted campervan is one of the trickiest parts of van life. Most mainstream insurers won't touch a DIY build. But there are specialists who will — if you know where to look.
The Problem
When you convert a panel van into a campervan, you've changed its classification. It's no longer a commercial vehicle — it's a motorhome. But the DVLA and insurance companies don't automatically recognise your conversion. You need to prove it meets their criteria.
What You Need Before Insuring
DVLA Classification
You need to change the vehicle's classification from "panel van" to "motorhome" with the DVLA. This requires:
- Form V627/1: Application to change vehicle classification
- Photographs: Interior showing fixed bed, kitchen, seating
- Evidence of conversion: Receipts, invoices, photographs of work
- MOT certificate: If the vehicle is over 3 years old Without DVLA classification, most insurers will refuse cover or charge you commercial van rates.
Insurance Group
DIY conversions often fall into higher insurance groups because insurers can't assess the conversion quality. This can push premiums up by 20-50%.

How to Get the Best Deal
Declare Everything
Don't hide the fact it's a DIY conversion. Insurers will find out when you claim, and they'll void your policy.
Get Specialist Quotes First
Mainstream insurers often charge more for conversions. Start with specialist campervan insurers.
Use a Broker
Campervan insurance brokers like Adrian Flux and CIA Insurance have relationships with多家 insurers. They can find deals you won't find online.
Consider Telematics
Some insurers offer black box policies that track your driving. This can reduce premiums by 10-20% for careful drivers.
Increase Excess
A higher excess reduces your premium. Set it at a level you can afford if you need to claim.
Typical Costs
| Insurer Type | Annual Premium | Notes |
|---|---|---|
| Specialist campervan | £250-400 | Best for DIY builds |
| Mainstream with conversion | £350-550 | Higher premiums |
| Commercial van rate | £500-800 | Avoid this |
Common Mistakes
- Not declaring the conversion: Invalidates your policy
- Using commercial van insurance: Doesn't cover personal use
- Forgetting to update the V5C: Insurers check the registration
- Not taking photographs: Insurers want proof of the conversion
Conclusion
Insuring a DIY campervan is possible but requires preparation. Change the DVLA classification first, gather your documentation, and go to specialist insurers. Don't try to hide the conversion — it will only cause problems when you claim.
