Aldi Launches National “Supermarket Sweep” Fundraiser
In an official corporate announcement issued on 7 July 2026, discount supermarket giant Aldi confirmed it is launching its legendary “Supermarket Sweep” initiative across England and Wales for the first time. The fundraiser, which has operated successfully across Scotland for a decade and raised over £60,000 for local causes, is being scaled up nationally in a corporate partnership with the Teenage Cancer Trust.
The competition structure allows ten selected winners across the regions to participate in a five-minute trolley dash at their local store. Participants keep the contents of their trolleys, and Aldi will donate the exact cash value of the gathered goods directly to the Teenage Cancer Trust.
Key Timelines for Applicants:
- Applications Opened: 00:01 on Monday 6 July 2026
- Applications Close: 23:59 on Monday 3 August 2026
- How to Enter: UK shoppers must email their personal details to
aldisupermarketsweep@aldi.co.ukwithin the open window.
This promotional surge coincides with independent data from consumer champion Which?, which named Aldi the UK’s cheapest supermarket for June 2026. The announcement completes a flawless first-half clean sweep for the retailer, which has secured the monthly affordability crown for six consecutive months in 2026.
M&A Update: CMA Approves ABF Acquisition of Hovis
In a significant corporate consolidation for UK supply chains, Associated British Foods (ABF) announced in its Q3 2026 trading update that the UK Competition and Markets Authority (CMA) has officially approved its acquisition of Hovis Group Limited.
The move permits ABF to merge the operations, production facilities, and distribution corridors of Allied Bakeries (producers of Kingsmill) with the Hovis brand. According to ABF’s executive brief, the combination is engineered to secure cost synergies that will insulate the business against volatile wheat commodities while funding long-term product innovation. Financially, ABF reported a steady 1% constant-currency revenue growth within its broader grocery division for the third quarter of 2026, driven by solid performance in its international brands like Twinings.
Market Share & Inflation: The True Cost of the Weekly Shop
The Great Britain grocery sector is currently valued at an estimated £235 billion annually. Long-term analysis of consumer panel tracking indicates that the aggressive market share displacement caused by the discounter boom between 2021 and 2023 has entered a period of relative equilibrium.
Tesco maintains a firm structural grip on the top spot, bolstered by its highly sticky ecosystem of 20 million active Clubcard households. Sainsbury’s continues to defend its second-place position through the deployment of Nectar Prices and steady investment in its premium Taste the Difference tier.
Great Britain Grocery Market Share Rankings (12-Week Tracking)
| Retailer | 2017 Market Share (%) | 2026 Market Share (%) | Structural Shift (Percentage Points) |
| Tesco | 28.0% | 27.3% | -0.7 |
| Sainsbury’s | 15.7% | 15.1% | -0.6 |
| Asda | 15.6% | 13.7% | -1.9 |
| Aldi | 6.6% | 10.2% | +3.6 |
| Morrisons | 10.4% | 9.2% | -1.2 |
| Lidl | 5.2% | 8.1% | +2.9 |
| Waitrose | 5.1% | 4.4% | -0.7 |
| M&S Food | 3.8% | 4.1% | +0.3 |
| Co-op | 4.9% | 3.9% | -1.0 |
| Ocado | 1.3% | 1.8% | +0.5 |
The Structural Macro-Trend: Between 2017 and 2026, the traditional “Big Four” (Tesco, Sainsbury’s, Asda, Morrisons) saw their collective market dominance decline from 73.3% to 65.3%. This combined drop of 8.0 percentage points corresponds exactly with the 8.0 percentage point gain achieved by Aldi and Lidl over the same nine-year frame, with their combined footprint climbing from 10.3% to 18.3%.
Inflation vs. The Reality on the Shelves
While the Office for National Statistics (ONS) confirmed that the individual annualized rate of food price inflation dropped to 2.2%, data compiled by consumer advocacy groups such as The Food Foundation reveals a deep disparity in cumulative costs.
The baseline price of a standard weekly food basket has risen significantly since the initial cost of living shock. A standard shopping basket now averages £53.51 for a single woman and £60.24 for a single man—representing a sharp multi-year price escalation of 30.6% and 38.4% respectively since April 2022. Overall, cumulative grocery shelf prices across the UK sit 30.5% higher than they did four years ago, demonstrating why public perception of grocery costs remains strained despite cooling headline inflation figures.

Expert Insight
“The widening gap between stagnant wholesale prices paid to farmers and the elevated prices consumers pay at checkout highlights a deep lag effect in retail economics. Historically, supermarket shelf prices require anywhere from six to twelve months to drop even marginally following a wholesale market stabilization. This delay is largely driven by long-term corporate hedging contracts and rising internal operational overheads, including statutory minimum wage increases and national insurance adjustments. While supermarkets are largely cleared of direct profiteering by regulatory investigations, the structural reality means consumers will bear the weight of this 30.5% cumulative price inflation plateaux for the foreseeable future.”
Frequently Asked Questions
Which supermarket is officially the cheapest in the UK for 2026?
According to independent monthly testing by consumer champion Which?, Aldi has been named the UK’s cheapest supermarket for June 2026. This achievement marks a consecutive six-month sweep for the first half of calendar year 2026.
How do I enter the Aldi Supermarket Sweep in England and Wales?
Shoppers can enter by emailing their full contact details to aldisupermarketsweep@aldi.co.uk. The competition officially opened on Monday 6 July 2026 and will accept entries until 23:59 on Monday 3 August 2026. Ten winners will be chosen to complete a 5-minute trolley dash.
What is the current rate of food inflation in the UK?
The annualized rate of food price inflation dropped to 2.2%. However, despite this slowdown in the speed of price increases, cumulative food prices have risen by 30.5% overall since April 2022.
Who owns Hovis bread now?
Following formal regulatory clearance by the UK Competition and Markets Authority (CMA) in July 2026, Hovis Group Limited has been acquired by Associated British Foods (ABF), merging its manufacturing footprint with Allied Bakeries.
Who has the highest market share in the UK grocery industry?
Tesco remains the dominant market leader with a 27.3% share of the Great Britain grocery market. Sainsbury’s sits in second place at 15.1%, followed by Asda at 13.7%, and Aldi at 10.2%.
Why are supermarket prices still high if inflation has dropped?
Inflation measures the rate at which prices rise, not a reduction in price. Because grocery costs experienced a cumulative jump of over 30% since 2022, a low inflation rate of 2.2% simply means prices are flattening out at this higher level rather than getting cheaper.
What are the top three supermarkets in Great Britain?
The top three retailers by grocery volume and value are Tesco (27.3%), Sainsbury’s (15.1%), and Asda (13.7%). Together with fourth-place Aldi, they control the vast majority of consumer food spend.
