Royal Mail is modernising its iconic red post boxes with a smart, customer-friendly twist. In a move that’s set to benefit small businesses, online sellers, and everyday senders alike, 3,500 solar-powered post-boxes are being rolled out across the UK. These upgraded boxes are designed to accept parcels as large as a shoebox, making it easier than ever to post packages without needing a trip to the Post Office.

What’s Changing?

For nearly two centuries, Royal Mail’s post boxes have been a staple of British streets. But until now, their size has limited what could be posted. The new solar-powered versions feature wider parcel slots, allowing for parcels that previously wouldn’t fit. This is a game-changer for anyone sending medium-sized items, especially during busy periods like Christmas or peak e-commerce seasons.

Rollout Timeline and Locations

The rollout began in August 2025, following a successful pilot earlier in the year. Royal Mail plans to install 3,500 of these upgraded post boxes across the UK over the coming months. Cities where the new post boxes are already available include:

• Edinburgh
• Manchester
• Nottingham
• Sheffield
• Sunderland

More locations are expected to follow soon, making it easier for customers nationwide to post parcels conveniently and securely.
