Stimulus check - taxable in the UK?

I am hoping to receive my stimulus check soon after having filed for US taxes in 2018 and 2019 (I hope!).  Would the UK consider this to be taxable income?  The US does not, but I wonder how this would be viewed in the UK?  I will be calling HMRC at some point (the wait is probably crazy at them moment, so I will hold off), but I have found the call centre advice to not always be reliable/consistent about foreign income.  I am a full-time resident of the UK now.

Good question and I don’t know the answer. Sorry.

I don’t qualify myself, but my son does.

I have wondered the same thing, but my gut reaction is, that it won't be taxable.

I am basing that OPINION on the stimulus technically being an advance "tax refund" for 2020, despite the fact that you don't pay it back nor does it in any way ultimately affect your 2020 refund (if any) or result in a tax liability.
