Claiming a generic builders invoice as a taxable expense

[jtufty]

Hi,

I have a rental property. I had builders do work on my personal property, but they also did work on the rental (fixing some render and a chimney leak). They invoiced me a generic £6k invoice for 'Property Maintenance' and addressed it to my rental property.

Of course, Im not going to claim the whole amount as a business expense, because... well... it wasnt. But I estimate about £2k of it was.

However, I have since fallen out with the builders and cant go back to them to itemise the invoice.

So, should I claim the £2k and make a note of my reasoning why its £2k? (approx time builders spent working on the rental property, plus I did take a few photos), or should I not bother trying to claim any of it and risk an investigation/enquiry?

Yes go ahead if you know what work was done on both properties

Thanks. What notes/evidence do you think HMRC will find acceptable (if they enquire)? I could give an approximate amount of days they worked on the rental property, a list of hte few jobs they did, and the invoice they gave me addressed to the rental address (albeit it £4k more than what Im claiming expenses for). I have a few photos which I took, but not with the intention that they would provide evidence for HMRC, so not sure how helpful theyd be.

I dont even have anything written down between me and the builder.

Is there anything else that may help evidence, should HMRC enquire?
