Hi,
I have a few items like laptop cellphone and satnavi that I used being selfemployed and claimed FYE 50% of value in self assessment. Now I run a company and want to include them and calculate depreciation of these items. How should I do it? please help

Bring the Value of the Assets as it is standing now into your NEW set of books.
At the end of the financial year calculate the
depreciation that is allowable on these assets.
