Working from a Motorhome

[malvolio]

Can I jump on the thread? I have a similar situation , but it's a campervan, I'm an agency nurses I will use it when working away from home.
I own it privately, so I guess I could claim back some milage and the pitch..
What about maintenance and the modification costs to the campervan (I'm converting it from a van).
Is there any way to claim those costs as ltd?

Quick answer - No.

Longer answer - it will immediately fail the "wholly and exclusively for business" test. YourCo is not a magic money pit, it is separate from you in all aspects, which explains a lot about what you can and can't claim. That includes its assets: YourCo can obviously own the vehicle and convert it, but you personally will get taxed every time you use it. And, of course, you would have to sell it the van at a commercial valuation.

As an aside, you will also have to ensure it is re-classified as a motorhome with DVLA rather than as a van, for various reasons (not least speed limits...). That may not be as simple as you may think.
