This is the official UK Government statement on the crisis grants available to self-employed drivers.
Note that despite the title mentioning 'claim a grant', you don't have to do anything at this stage. As stated further down, HMRC will contact you automatically in due course, and you will then have to complete an online form to claim the grant. (Or at least HMRC will contact you if you're registered as self-employed with them

)

This scheme will allow you to claim a taxable grant worth 80% of your trading profits up to a maximum of £2,500 per month for the next 3 months. This may be extended if needed.
Who can applyYou can apply if you’re a self-employed individual or a member of a partnership and you:
• have submitted your Income Tax Self Assessment tax return for the tax year 2018-19
• traded in the tax year 2019-20
• are trading when you apply, or would be except for COVID-19
• intend to continue to trade in the tax year 2020-21
• have lost trading/partnership trading profits due to COVID-19
Your self-employed trading profits must also be less than £50,000 and more than half of your income come from self-employment. This is determined by at least one of the following conditions being true:
• having trading profits/partnership trading profits in 2018-19 of less than £50,000 and these profits constitute more than half of your total taxable income
• having average trading profits in 2016-17, 2017-18, and 2018-19 of less than £50,000 and these profits constitute more than half of your average taxable income in the same period
If you started trading between 2016-19, HMRC will only use those years for which you filed a Self-Assessment tax return.
If you have not submitted your Income Tax Self-Assessment tax return for the tax year 2018-19, you must do this by 23 April 2020.HMRC will use data on 2018-19 returns already submitted to identify those eligible and will risk assess any late returns filed before the 23 April 2020 deadline in the usual way.
How much you’ll getYou’ll get a taxable grant which will be 80% of the average profits from the tax years (where applicable):
• 2016 to 2017
• 2017 to 2018
• 2018 to 2019
To work out the average HMRC will add together the total trading profit for the 3 tax years (where applicable) then divide by 3 (where applicable), and use this to calculate a monthly amount.
It will be up to a maximum of £2,500 per month for 3 months.
We’ll pay the grant directly into your bank account, in one instalment.
How to applyYou cannot apply for this scheme yet.
HMRC will contact you if you are eligible for the scheme and invite you to apply online.
Individuals do not need to contact HMRC now and doing so will only delay the urgent work being undertaken to introduce the scheme.
You will access this scheme only through GOV.UK. If someone texts, calls or emails claiming to be from HMRC, saying that you can claim financial help or are owed a tax refund, and asks you to click on a link or to give information such as your name, credit card or bank details, it is a scam.After you’ve appliedOnce HMRC has received your claim and you are eligible for the grant, we will contact you to tell you how much you will get and the payment details.
If you claim tax credits you’ll need to include the grant in your claim as income.
Other help you can getThe government is also providing the following additional help for the self-employed:
If you’re a director of your own company and paid through PAYE you may be able to get support using the
Job Retention Scheme.
