The retailer is pushing the boundaries of retail grocery deliveries by rolling out the service to reach almost all corners of Britain.
The grocery delivery expansion, which includes fresh fruit and vegetables, gets underway at the end of August and extends the same-day delivery service that started in 2014.
This was when the retailer first offered the service to postcodes in London and the South East.
Within a few weeks it will be extended to more than 300 stores nationwide, covering 99% of British households from the Shetland Islands in Scotland to the most southerly points of Cornwall, according to the supermarket.
“Customers tell us they like getting their shopping delivered quickly and conveniently, and with our same day delivery service they can now order by lunch to get their shopping delivered for their evening meal,” says Adrian Letts, managing director of Tesco Online.
“We’ve seen the service grow in popularity since we launched it in London and the South East so we’re really excited to be rolling it out to customers nationwide.”
Tesco says the service is the biggest reach of any retailer in the UK. Shoppers can order by 1pm to have an unlimited amount of groceries delivered from 7pm onwards.
The new service is priced between £3 and £8. It is available seven days a week in London and the South East and from Monday to Saturday across the rest of the UK.
Tesco has seen an 18% growth in demand for the same-day service throughout 2017 and earlier this year extended its same-day Click+Collect service to 300 locations across Britain.
