Work from home allowance

Hi HMRC, I am a BNO Visa holder, my employment is in contract basis and work from home basis (no office provided from my employer) from day one (since Jun 2021). Can I claim the £6 per week working from home allowance since Jun 2021 that I have to work at home? - If yes, how can I claim the allowance for the tax year (2022-2023)? Is it under the Self Assessment form? Or somewhere in the website? - Also how can I claim the allowance for the tax year (2021-2022) Many Thanks

Hi Danny,
You cannot claim tax relief if you choose to work from home.
This includes if:
your employment contract lets you work from home some or all of the time
you work from home because of coronavirus (COVID-19)
your employer has an office, but you cannot go there sometimes because it’s full.
Thank you.
