The NHS Covid-19 app is set to be updated from August 16 to allow double jabbed people to add their vaccination status to skip isolation.
The NHS Covid-19 app currently sends isolation notices to close contacts of people five days prior a positive test, but this will be reduced to two days.
The government has announced the sectors where workers may qualify for an exemption to self-isolation rules if they are pinged by the NHS Covid-19 app.
Transport secretary Grant Shapps has said the NHS Covid-19 app may need to be updated in line with coronavirus restrictions easing on July 19.
The newly published procurement contract for the NHS Covid-19 app is valued at £10.26m and covers a period of six months from March to September.
Announcing the countries that will be on the UK’s ‘green’ travel list the transport secretary said the app would be used as a Covid-19 passport from 17 May.
Grant Shapps confirmed the app will be used a Covid-19 passport to prove vaccination status, or negative test, before going on holiday.
The update to the NHS Covid-19 app is due to be rolled out before venues including non-essential shops, gyms and outdoor hospitality open on 12 April.
A developer of the NHS Covid-19 app has said it is a “highly effective” tool to help control the spread of the virus as the UK exits lockdown.
Data on the NHS Covid-19 app is to be published weekly alongside NHS Test and Trace data from next week, the Department of Health and Social Care has said.
