UK: B&M Paradox - Growing Sales, Shrinking Profits
Discount Variety Retail Chain B&M, Britain’s largest variety discounter with 799 UK stores, has long been a masterclass in discount retailing. Built from a small northern chain into a national powerhouse by Simon Arora and his brothers, the retailer delivered consistent profitability, until recently.
In the year to March 2026, B&M’s sales climbed from £5.57bn to £5.78bn, yet pre-tax profit halved, dropping from £431m to £227m. The same £204m gap, moving in opposite directions. New Dutch CEO Tjeerd Jegen arrived in June 2025 to find a business that looked healthy on the surface: sales were up, nearly every store was profitable, and price checks showed its grocery basket was ~15% cheaper than major supermarkets.
So how does a retailer this effective at being cheap keep growing, stay cheaper than Tesco, and still lose a quarter of its trading profit?
The answer lies in three critical blind spots—lessons every discount retailer must heed.
Lesson 1: New Stores Can Mask Stagnation in Existing Ones
The Trap
Total sales are the headline metric in any retail board report. And for good reason: every new store generates revenue from day one. For B&M, 41 new UK openings (net +22 after closures) drove £132m in incremental sales—while like-for-like sales across existing stores fell 0.1%. The year before? Down 3.1%.
Yet over 99% of B&M’s stores were individually profitable, and each new location passed its internal ROI test. The result? A growing top line that obscured a deeper issue: existing stores were not growing.
DRC’s Insight
When expansion is the primary growth driver, disaggregated performance metrics become essential.
Track:
Like-for-like sales growth (not just total sales)
Profit per square metre across store cohorts (new vs. mature)
Cannibalisation rates between new and existing locations
Takeaway: If your existing estate isn’t growing, new stores may be hiding a demand problem—not solving it.
Lesson 2: Average Prices Don’t Reflect Competitive Reality
The Blind Spot
B&M’s internal price tracking compared a basket of ~3,000 grocery and household lines against supermarkets, confirming a ~15% price advantage—even after loyalty card discounts. But here’s the catch: customers don’t shop by average basket price.
For most shoppers, B&M is a supplementary trip—a detour to save on a few high-usage items. If washing-up liquid is cheaper on a Tesco Clubcard, the core reason for that trip weakens. Multiply this across a few key products, and the entire store feels expensive.
The Revelation
In August 2025, Jegen’s team audited 450 high-velocity SKUs—representing ~20% of grocery sales—and found 35% needed price cuts to remain competitive. B&M’s broad price index had masked critical gaps in its most shopped products.
DRC’s Insight
Discount retailers must:
Weight price tracking by sales volume, not just SKU count
Monitor "trip driver" products separately (the items that pull customers in)
Stress-test against loyalty schemes (e.g., Tesco Clubcard, Sainsbury’s Nectar)
⚠️ Takeaway: Average prices lie. What matters is the price of the products your customers buy most often.
Lesson 3: Full Shelves ≠ Happy Customers
The Illusion of Availability
B&M’s store audits prioritised visual merchandising: shelves had to look full and tidy. But a full shelf of the wrong product is still an empty shelf for the customer.
In H1 2026, only 86% of B&M’s bestselling grocery lines were in stock in monitored stores—12 points below the 98% industry standard. For a discounter, where the value proposition is built on reliable savings, missing one in seven popular items is a critical failure.
The Root Cause
Over-assortment: Too many SKUs competing for limited shelf space and staff time
Misaligned incentives: Store teams optimised for appearance, not availability
Replenishment gaps: Inefficient routines led to stockouts on high-demand lines
The Fix
B&M tested new replenishment processes on 240 popular grocery SKUs across 11 stores. Availability jumped to ~94%. After wider rollout, bestselling brand availability reached 93% in H2. The retailer also plans to cut ~20% of grocery SKUs, freeing up space for what customers actually buy.
DRC’s Insight
For discount retailers, availability is the ultimate loyalty driver. Prioritise:
ABC analysis: Focus on A-grade (high-velocity) SKUs
Store-level planograms tailored to local demand
KPIs tied to in-stock rates for bestsellers, not just visual standards
Takeaway: Measure what matters to customers—product availability—not just what looks good in audits.
The Strategic Playbook for Discount Retailers
B&M’s challenges are not unique. They reflect three universal risks in discount retail:
Risk | Symptom | Solution |
Expansion masking stagnation | Rising total sales, flat LFL growth | Track mature store performance separately |
False availability metrics | Full selves, frequent stockouts on bestsellers | Measure in-stock rates for top SKUs; simply assortment |
Misleading price competitiveness | Strong average basket price, weak SKU-level pricing | Weight price checks by volume; monitor trip drivers |
