Start up costs - tax deductible?

I left me job in October having earned £70,000 so far in 23/24 (including the taxable part of a redundancy payment ). I am now setting up a business. Can I offset start-up costs of £10,000 against my overall income for the year? Would that be at £40,000?

Hi Ash Gordon,
Pre-trading expenses incurred 'wholly and exclusively' in relation to a new sole trader business can be treated as expenses incurred on your first day of trading.                                                  Expenses if you're self-employed
Thank you.
