Convenience Boost: Sainsbury's Partners with Royal Mail

Royal Mail is working with Sainsbury’s to install parcel lockers in supermarket car parks across the UK, giving shoppers new ways to send and collect parcels as part of their routine.

The supermarket is the first of its kind to partner with Royal Mail on its parcel locker network and the deal marks a major expansion in how delivery services are embedded into everyday life.

Lockers are already in place at stores in Clapham, Desborough, Kempshott, Low Hall, Kidderminster and Chislehurst. The rollout continues over the coming months, with the aim of making delivery services more convenient and accessible to more people. 

Royal Mail launched its locker service in December to support the growing number of people buying and selling goods through secondhand marketplaces - and to ease demand created by online shopping.

Jack Clarkson, Group Strategy and Transformation Director at Royal Mail, comments: “Partnering with a retailer with the scale and popularity of Sainsbury’s is great news for our customers and the UK public, who will now have even more ways to drop off and collect their parcels in convenient locations.”

 Bringing parcel services to the weekly shop

Unlike traditional postboxes, Royal Mail lockers at Sainsbury’s stores are standalone units placed in supermarket car parks. They are accessible seven days a week and are designed for both sending and collecting parcels.

The process starts online: customers pay for postage, then scan a QR code at the locker to print their label or use a pre-generated return code. This cuts out the need for a printer at home.

The service is aimed at anyone looking for a quick way to manage parcels while shopping and it offers low-cost options too, with prices starting at US$1.55 for a small parcel that fits through a letterbox. With secondhand sales on the rise, many are using these lockers to send clothes, books or home goods bought through platforms such as Vinted or eBay.

Patrick Dunne, Chief Property and Procurement Officer at Sainsbury’s, says: “The lockers will be available seven days a week, giving customers an easy, convenient way to drop off and collect parcels via Royal Mail as they shop.”

The expansion forms part of a wider Royal Mail strategy to increase its presence in public spaces. Customers can now access more than 1,500 parcel lockers and 7,000 Collect+ points, alongside Royal Mail’s 11,500 Post Office branches and 1,200 Customer Service Points.

The Sainsbury’s lockers are also helping Royal Mail reduce pressure on its delivery routes.

By encouraging more parcel drop-offs at local hubs, the company can consolidate collections and cut down on van journeys, supporting a more sustainable approach to logistics.

Smart postboxes mark an upgrade to street services

While Royal Mail lockers at Sainsbury’s are focused on expanding access through retail spaces, the company is also revamping its street-level infrastructure.

Postboxes are being adapted to accept small barcoded parcels, and in some areas, new solar-powered versions are being trialled to support changing parcel habits.

These redesigned postboxes feature an extra-large opening for parcels that wouldn’t fit through a standard slot.

The process is simple: customers scan the parcel’s barcode, a drawer opens and the parcel is dropped in. They can then request proof of postage using the Royal Mail app. These smart boxes are currently being piloted in Ware, Hertford and Fowlmere.

Emma Gilthorpe, CEO at Royal Mail, describes the changes: “We are giving our iconic postboxes a new lease of life on street corners across the nation. 

"You can now drop your parcel in any postbox where it fits – you just need a label with a barcode.”

This development supports sellers who regularly post small items, offering them a quick and reliable way to dispatch goods without visiting a Post Office. It also enables returns to be managed more easily, making the secondhand economy more practical.

The updated postboxes work alongside Royal Mail’s app, which uses 4G and location tracking to confirm proof of posting. Customers tap ‘services’, choose ‘proof of posting’ and follow the steps to register their drop-off. It’s a small change that simplifies the experience for people sending parcels without needing a physical receipt.

There are 115,000 postboxes in the UK and Royal Mail says that 98% of addresses are within half a mile of one. While current postboxes are limited to parcels that fit through a letterbox, thousands could be adapted to accept larger sizes in the future. The company’s aim is to make its network the most accessible in the country.

Both the new lockers and the updated postboxes reflect Royal Mail’s focus on meeting customers where they are - whether in the supermarket car park or on their local street - and doing so in a way that supports greener logistics, fewer journeys and faster access.
