Bike related tax question

[TheLemming]

Bit of an unusual one - my usual sources on tax related bits haven't run into it before and I'm looking for an idea of where to go with this.

I'll be in a position next year to be riding for a living, leading group riding holidays for much of the year and back to my day job in the meantime. I love riding, pure and simple and I'll get to do more.

Given that I should be able to claim a new road bike against tax as a work expense - along with kit, in the same manner that tools or ppe are claimable for any other occupation?

Its the proposed 4 grand price tag that seems to make my umbrella company nervous....

I don't suppose anyone is able to help me point them in the right direction?

I've started to type a long reply explaining what why and where and instead of hitting post it's occurred to me that a long explanation of my specific financial arrangements and tax situation isn't perhaps the best thing in the world to drop on the internet.

As a result I should say "thanks guys" and live through the long and life draining process of querying it directly with HMRC.
