Is it possible to partially change an existing self employed business name? -

currently trading as a business consultant,want to become a retailer with the same self employed name.Can I change my business name from consultancy to traders?

if you are just a sole trader then yes, you simply change the name and inform hmrc of the change, if you are changing the nature of what you do as well then i d suggest starting a new set of accounts so when you do your tax return you can easily separate the two
