The Coca-Cola owned coffee shop business says it will reopen an additional 31 drive-through locations, as well as 15 takeaway sites.
As well as takeaway, delivery will be available at all locations via UberEats.
Costa began a phased reopening of sites late last month, having closed its entire portfolio back in March due to the Coronavirus pandemic.
This process has allowed the business to trial social distancing in its stores, implement enhanced hygiene procedures, and adapt operations to keep both staff and customers safe.
Teams have been provided with PPE, and all sites will for the time being only accept contactless payment.
"We have received some great feedback from our store team members and customers have responded well to our new ways of working,” says Costa CEO Jill McDonald.
“This has given us the confidence to re-open some more stores.”
Earlier this week, high street rival Starbucks announced the reopening of approximately 150 takeaway and drive-thru stores across the UK.
Meanwhile, Caffè Nero says it would have reopened a further 33 sites in its estate by the end of next week, as it continues to move forward with a takeaway-only trial of its operations.
