Universal credit and mileage

Sunnyuk5

I am a sub contractor where my client assigns me to support some of their clients (schools).

I mainly work from home and do visit schools regularly. But they are not the same place. Different locations and not fixed.

Had my universal credit self employment review appointment and they said I should stop putting in mileage expense as I'm not using my vehicle for business purposes. I had been putting this expense on my uc income and expenditure for 8 months. They said not to worry about recording it before.

I explained I was using my car for business purposes and have a mileage log. They still said I shouldn't put in mileage expense and hmrc ruling may differ from uc regarding this, as I said I always put in mileage expense as a tax deductible expense when doing my payroll.

They are saying something like an uber driver or delivery driver can put in uc mileage expense. But not me in this scenario. He was one of the self employment experts for uc at the job centre.

Any advise?
