I have mine on the 15th of July. Close call 
If you’re a vehicle owner in England, Scotland or Wales, and the MOT for your car, motorcycle or van expires on or after 1 August 2020, you will be affected. Your certificate will not be extended and you’ll need to book an MOT test as you would have done before lockdown.
If your MOT was or is due between 30 March and 31 July 2020, you will still be granted the full six-month extension. So if, for example, your MOT is due on 30 July 2020, you won’t need an MOT check until 30 January 2021. This applies to both MOT renewals and vehicles due their first MOT test in this period.
