Aldi, Lidl, Sainsbury's Lead 2026 Supermarket Expansion Across UK
Supermarkets Open New Stores in 2026: Full List

In a surprising turn for the UK's retail landscape, several major supermarkets are bucking the trend of high street closures with ambitious new store openings planned for 2026. While many shops have shuttered in recent years, these retailers are investing heavily to expand their presence, offering a glimmer of hope for local economies and consumers alike.

Supermarket Giants Defy the Odds

Despite widespread reports of shop closures and economic challenges, it's not all doom and gloom on the high street. A host of new supermarkets are set to open their doors in 2026, with Lidl, Aldi, and Sainsbury's leading the charge. This expansion signals a robust commitment to growth in the face of adversity, as these chains aim to capture market share and serve communities across the nation.

Lidl's Aggressive Expansion Plans

Leading the pack, Lidl has an impressive 19 new supermarkets on the cards for this year. The discount retailer is not only launching these outlets but also awaiting approval for a new branch in Croxteth, which it hopes to secure in the coming months. The full list of Lidl's new locations includes:

  • Basildon, Laindon
  • Birmingham, Kingstanding
  • Brough, Welton Road
  • Burntwood
  • Calne
  • Chester, Caldy Valley Rd
  • Dereham
  • Havant, Purbrook Way
  • Hereford, Belmont Road
  • Horley
  • Hucknall, Watnall Rd
  • London, Stamford Hill
  • London, Walworth Road
  • Reading, Tilehurst
  • Royal Wootton Bassett
  • Salisbury, Churchill Way West
  • Sandford
  • Sutton High Street
  • Tring

This widespread rollout underscores Lidl's strategy to strengthen its footprint in both urban and rural areas, providing affordable options to a broader customer base.

Aldi's Significant Investment in Growth

Aldi is setting its sights even higher, with plans to open 40 new branches in 2026. The supermarket chain has revealed a substantial investment of £370 million in new store openings across Britain this year. Key locations for Aldi's expansion include:

  • Amersham
  • Kennington
  • Hastings
  • Southam

This move highlights Aldi's aggressive growth strategy, as it continues to challenge traditional retailers with its low-price model and expanding product range.

Other Retailers Joining the Expansion

Sainsbury's is also part of this retail resurgence, with a new store planned in Witney. Additionally, other retailers are contributing to the high street's revival:

  • Co-op: Opening in Ashford
  • The Food Warehouse: Expanding in Ballymena
  • Holland & Barrett: Launching in Maidstone

These openings reflect a broader trend of supermarkets and specialty stores investing in new locations, potentially revitalising local high streets and creating jobs.

Implications for the UK Retail Sector

The planned store openings by Aldi, Lidl, Sainsbury's, and others in 2026 suggest a shift in the retail sector. While online shopping continues to grow, these physical expansions indicate that supermarkets see value in maintaining and expanding their brick-and-mortar presence. This could lead to increased competition, better prices for consumers, and a boost for communities facing economic challenges.

As reported by sources like the Express, this full list of supermarket openings offers a detailed look at what's in store for the upcoming year. With millions of pounds being invested and dozens of new jobs likely to be created, 2026 could mark a positive turning point for the UK's high streets, proving that not all retailers are retreating in the face of change.
