The service, called Ultra Fast Fresh, would aim to bring rapid grocery delivery to some 40% of UK households by the end of the year and would see Amazon retrofit nine existing depots across the country to handle fresh produce and fulfil deliveries, according to The Grocer.

The first depot to be retrofitted will be located in London, with the next earmarked for Leeds.

Citing suppliers of the ecommerce giant in the UK, the service could involve making Amazon Fresh – its grocery delivery service – a free benefit of Prime membership in the country, rather than a monthly add-on.
