Tesco's Fuel Surge Masks a Softer Growth Story

What the fuel surge actually tells us

Fuel sales at Britain's largest supermarket jumped 19.5 per cent to £1.7bn in the three months to May, according to the company's Q1 trading statement filed with the London Stock Exchange. Total revenue, including VAT and fuel, rose four per cent to £14bn. Underlying like-for-like sales growth, however, slowed to just one per cent, with total sales excluding fuel reaching £16.8bn.

The divergence is stark. In the full year to February, fuel revenue had actually fallen six per cent to £5.9bn, a decline Tesco attributed to lower pump prices. The reversal this quarter is almost entirely a function of geopolitics rather than volume gains.

Petrol prices hit 159p per litre in late May, the highest since Russia's invasion of Ukraine in 2022, while diesel peaked at 191p per litre in mid-April, according to RAC data. Both spikes were driven by the effective closure of the Strait of Hormuz during the Iran conflict, which disrupted crude flows and sent wholesale energy costs sharply higher.

Tesco operates roughly 600 petrol stations across the UK. Higher pump prices mechanically inflate revenue without necessarily improving margins; fuel retailing is a low-margin, high-turnover business at the best of times. The RAC has said it expects prices to ease as the Strait reopens, which would remove the tailwind as quickly as it arrived.

For any business that relies on fuel, whether haulage, last-mile delivery, or simply commuting staff, the quarter is a reminder of how quickly geopolitical disruption feeds through to operating costs. For Tesco, it is a reminder of how volatile a contributor fuel can be to headline numbers.

Core grocery: growth or price-match pressure?

Beneath the fuel noise, Tesco's food business delivered 2.6 per cent sales growth in the quarter, with fresh food up 3.6 per cent, according to the trading statement. Those are respectable numbers, but they need context.

Tesco's grocery market share has risen to 28.2 per cent, a figure the company says exceeds the combined share of its two closest rivals, Sainsbury's and Asda. Market leadership of that scale carries its own gravitational pull: suppliers prioritise shelf space, customers default to familiarity, and promotional budgets flow towards the biggest audience. Sustaining share at this level, however, requires constant investment in price.

That investment is now intensifying. The company confirmed it has extended its Aldi price-match scheme to more than 2,000 of its convenience Express stores. The move is significant. Express stores carry higher operating costs per square foot than superstores, and price-matching a discounter across that estate compresses margins further.

"With the conflict in the Middle East creating ongoing uncertainty for many households, we remain focused on giving customers the very best combination of price, quality and service," chief executive Ken Murphy said in the trading statement.

The language is telling. Tesco is not framing the price-match expansion as an offensive play to win new customers; it is framing it as a defensive response to household budget pressure. Consumer confidence has fallen as inflation fears return, and the supermarket is betting that absorbing margin pain now will prevent share erosion later.

The company is simultaneously pushing its premium Finest range, adding more than 220 products in the quarter. Finest sales grew by nearly 12 per cent in the full year to February, and the range expansion suggests Tesco sees a bifurcating consumer: one cohort trading down on staples, another willing to pay more for quality. Managing both ends of that spectrum without cannibalising either is a perennial challenge for full-line grocers.

Booker's quiet decline and what it signals for wholesale

The weaker number in the trading statement received less attention but arguably matters more for the broader food economy. Revenue at Booker, Tesco's wholesale arm, fell three per cent to £2.2bn in the quarter.

Booker supplies independent retailers, pubs, restaurants, and food-service operators. A revenue decline there is not simply a Tesco problem; it is a barometer of demand across hospitality and convenience retail, two sectors that employ hundreds of thousands of people and sit at the sharp end of any consumer spending squeeze.

The trading statement did not break out the drivers of the decline in detail. Several plausible explanations exist: independent retailers cutting stock levels in anticipation of weaker footfall; food-service operators trimming orders as energy and wage costs rise; or a shift in purchasing patterns towards Booker's competitors. None of those explanations is reassuring.

Booker was acquired by Tesco in 2018 for £3.7bn and has been a reliable contributor to group earnings in most years since. A sustained softening would raise questions about the division's strategic fit and whether its margins can hold if the independent retail and hospitality sectors face a prolonged downturn.

For suppliers negotiating with Booker, the decline may also shift bargaining dynamics. A wholesaler under volume pressure has less room to absorb cost increases, which means those increases are more likely to be passed through to end customers or, alternatively, to result in tighter product ranges and fewer promotional slots.

Outlook: when the pump-price tailwind fades

Tesco restated its forward guidance for FY2026-27, forecasting retail operating profit of between £3bn and £3.3bn, unchanged from prior expectations despite the geopolitical backdrop. In the full year to February, pre-tax profit rose nine per cent to £2.4bn on revenue of £74bn, according to the company's preliminary results.

The decision to hold guidance steady is itself a statement. Management is signalling that it does not expect the fuel-driven revenue boost to translate into materially higher profits, nor does it expect the Booker weakness or price-match investment to drag earnings below the guided range. The implication is that these forces roughly offset each other.

That may prove correct in the near term. But the composition of growth matters. Revenue inflated by fuel prices that analysts expect to normalise is not the same as revenue driven by volume gains in core grocery. The RAC has indicated it expects pump prices to soften as the Strait of Hormuz reopens, and if that happens in the second quarter, the year-on-year fuel comparison will flatten rapidly.

At that point, the underlying one per cent like-for-like growth rate becomes the headline number. Whether Tesco can accelerate that figure while simultaneously investing in price-match programmes and absorbing input cost inflation will determine the shape of the full-year result.

Ken Murphy, who received total pay of £10.8m last year after a pay rise of more than £1m according to the company's annual report, will face that question at the half-year results. For now, the Q1 statement is a case study in how geopolitical shocks can flatter a top line while quietly tightening the conditions that drive sustainable growth.

The grocery sector, its suppliers, and the hospitality businesses that depend on Booker will be watching closely.
