Had a flood that the insurance wouldn't cover. As a result had to LG for the damage using money I had saved for Christmas. Was assured by workmen prior to and during work they would give me an invoice or receipt. I need this in order to prove to my stbxh the work was done and claim half the money back. Workmen know this. They are know completely ignoring me and refusing any paperwork/email/text message to say job done and paid. Would I be unreasonable to contact Hmrc to say it's highly unlikely they've not paid tax on this job? Really don't want to but also don't want to be £2.5k out of pocket at Christmas either!
