What the April GDP figures actually show
The headline number is modest. A 0.1% month-on-month contraction, as reported by the ONS on 12 June, does not on its own signal recession. But the direction of travel matters more than the magnitude.
Q1 2026 delivered strong output growth across all three major sectors. March alone contributed a 3% monthly GDP rise, according to the ONS, the strongest single-month reading in recent memory. April's reversal is therefore a sharp change in momentum rather than a deep fall in absolute terms.
At sector level, the ONS data pointed to weakness concentrated in production and manufacturing, where energy-intensive processes are most exposed to input-cost swings. Services output was broadly flat, while construction showed a marginal decline. The pattern is consistent with an energy-price shock feeding through unevenly: sectors with high power and fuel intensity absorbed the hit first.
For operators reading the monthly GDP release as a barometer of demand conditions, the more important signal is that consumer-facing services held up. Household spending has not yet retreated. The risk is that it does so with a lag, once higher energy costs filter into retail prices and erode real incomes.
How the Strait of Hormuz closure is hitting UK energy costs
The proximate cause of April's contraction is well understood. Iran's closure of the Strait of Hormuz, through which roughly 20% of global oil supply transits, has pushed Brent crude and wholesale gas prices sharply higher since March, as first reported by the Guardian.
The transmission mechanism into UK business costs runs through several channels. Wholesale electricity prices, which track gas prices because gas-fired generation remains the marginal source of UK power, rose in tandem. Diesel and petrol costs climbed, feeding directly into logistics and distribution overheads. Industrial gas users, from food processors to glassmakers, faced contract repricing at short notice.
For businesses on fixed-price energy contracts agreed before the crisis, the immediate impact has been limited. But many SMEs operate on variable or short-term contracts, particularly those that locked in rates during the relatively benign pricing environment of late 2025. Those contracts are now rolling over into a materially different cost base.
The comparison with the 2022 energy crisis is instructive but imperfect. In 2022, the UK had direct pipeline exposure to disrupted European gas flows. This time, the shock is routed through global oil markets and liquefied natural gas spot pricing. The effect on UK wholesale costs is real but somewhat buffered by greater LNG import capacity at terminals such as Milford Haven and the Isle of Grain.
Sector exposure: where operators feel it most
The distribution of pain is uneven, and operators in certain sectors face compounding pressures.
Manufacturing
Energy typically accounts for between 5% and 15% of total production costs in UK manufacturing, depending on the sub-sector, according to Make UK industry surveys. For energy-intensive industries such as steel, ceramics, chemicals, and paper, the proportion is far higher. April's GDP data showed manufacturing output declining, consistent with margin compression forcing some producers to slow or pause lines rather than operate at a loss.
Logistics and haulage
Diesel remains the dominant fuel for UK road freight. The Road Haulage Association has previously estimated that fuel constitutes roughly 30% of operating costs for a typical haulier. With diesel prices climbing through April, operators faced a familiar dilemma: absorb the cost and accept thinner margins, or pass it through via fuel surcharges and risk losing volume to competitors willing to hold prices.
Hospitality and food service
This sector sits at the intersection of higher energy bills for cooking, heating, and refrigeration, and higher input costs for ingredients transported by road. Margins in hospitality are already thin. Operators with multi-site estates face the additional complexity of managing energy contracts across different renewal dates and tariff structures.
Professional and digital services
Exposure here is lower but not negligible. Data centre operators and cloud-reliant businesses face rising power costs. Office energy bills, while a smaller share of total overheads than in manufacturing, still matter for firms occupying older, less efficient premises.
The practical question for all affected operators is whether to treat current energy prices as a temporary spike or a new baseline. Contract strategy depends on that assessment. Locking in at today's elevated rates protects against further increases but sacrifices upside if prices normalise. Staying on variable terms preserves flexibility but leaves margins exposed.
What to watch next: BoE response and Q2 outlook
The Bank of England's Monetary Policy Committee meets later this month, and the April GDP figure adds a layer of complexity to an already difficult rate-setting environment.
Higher energy costs are inherently inflationary. If the MPC judges that the Hormuz-driven price shock will feed through into headline CPI and, critically, into wage-setting behaviour, it may hold rates or even signal a delay to further cuts. That would compound the squeeze on business borrowing costs at precisely the moment when some operators need to invest in energy efficiency or restructure supply chains.
Conversely, if the MPC treats the shock as a supply-side event that will suppress demand and therefore be self-correcting, it could maintain its existing trajectory. The distinction matters enormously for finance directors planning capital expenditure and refinancing schedules.
Beyond monetary policy, several indicators will determine whether April's contraction is a one-month adjustment or the start of a sustained slowdown.
May and June PMI readings will show whether the manufacturing weakness deepened or stabilised. Early survey data from S&P Global has been mixed, with new orders softening but employment holding.
Consumer confidence surveys will reveal whether households are beginning to pull back spending in response to higher fuel and utility bills. A demand-side contraction would amplify the supply-side shock.
Geopolitical developments around the Strait of Hormuz remain the single largest variable. Any diplomatic resolution or partial reopening of the shipping lane would ease oil prices rapidly. Escalation would do the opposite.
For UK business operators, the April GDP figure is less a verdict than a warning. The energy-price transmission mechanism is functioning exactly as it did in 2022, compressing margins in exposed sectors and forcing difficult cost pass-through decisions. The difference this time is that businesses have recent experience of managing through a price shock. The question is whether the playbook from 2022, hedging, surcharges, efficiency programmes, demand management, proves adequate for a crisis with a different origin and uncertain duration.
