Headlines and what they mean

Boiler Upgrade Scheme: July 2026

The Department for Energy Security and Net Zero (DESNZ) has published the latest statistics for the Boiler Upgrade Scheme, confirming the allocation of £1.2 billion to support the replacement of inefficient gas boilers with low‑carbon alternatives. For commercial buyers, the scheme widens the pool of eligible technologies, including air‑source heat pumps and hybrid systems, and the deadline for applications is approaching. Engaging now can secure grant funding that reduces upfront capital costs and accelerates decarbonisation pathways. source

Heat Network Efficiency Scheme (HNES) – Round 13

DESNZ has opened Round 13 of the Heat Network Efficiency Scheme, inviting bids from operators to improve the efficiency of existing district heating networks. The scheme targets a 10 % reduction in heat loss and encourages the integration of renewable heat sources. Commercial energy users connected to qualifying networks can benefit from lower heat tariffs and improved system reliability, making it a timely opportunity for facilities with high heating demand. source

Gas system in transition: security of supply

A new consultation on the security of supply for the gas system in transition outlines DESNZ’s plan to diversify supply, expand storage, and accelerate the rollout of hydrogen blending. The paper flags potential short‑term volatility as legacy gas contracts unwind and stresses the importance of demand‑side response. Businesses should review their gas contracts and consider hedging or switching to flexible tariffs to mitigate exposure to any supply‑tightness that may arise. source

Capacity Market: Hydrogen to Power and interconnectors

DESNZ has launched a call for evidence on using hydrogen generation and new interconnector capacity within the Capacity Market. The evidence‑gathering exercise seeks commercial insight on the economics of hydrogen‑fired CCGT plants and the value of additional cross‑border capacity. For large energy users, the outcome could unlock new ancillary‑service markets and provide a revenue stream for on‑site hydrogen generation or demand‑response participation. source

Weekly road fuel prices

The latest weekly road‑fuel price statistics show diesel at £1.78 per litre and petrol at £1.71 per litre, reflecting a modest rise on the back of tighter global oil markets. Transport‑intensive businesses should monitor these figures closely, as fuel cost volatility can materially affect operating expenses and may justify revisiting fleet‑mix strategies or fuel‑hedging arrangements. source

Geopolitics and global markets

Global oil markets remain under strain. Chinese refiners are snapping up Iraqi crude as Gulf supply routes fracture, tightening the available supply for European refiners and nudging spot prices higher. Traders are bracing for an extended oil and LNG squeeze, with diesel cracks hitting £100 per tonne, signalling a tighter market than Brent prices alone suggest. Meanwhile, Russia’s internal fuel rationing adds another layer of uncertainty to European energy imports, and Saudi Aramco’s full September allocations to three European refiners underscore the limited flexibility in supply. These dynamics feed directly into UK wholesale power and gas pricing, especially as the domestic grid leans heavily on gas‑fired generation. source source source source source

The view from the trade desk

The grid forecast shows a carbon intensity of 190 gCO₂/kWh, classified as high, with gas supplying 45.2 % of generation, wind 27.6 %, nuclear 19.2 %, biomass 7.6 % and imports 0.4 %. The dominance of gas means that any supply‑side shock – whether from the DESNZ gas‑system consultation or from global oil market tightness – will be reflected quickly in wholesale power prices. Wind output remains robust, but the absence of coal and the modest contribution from imports limit the system’s flexibility. Commercial buyers should therefore keep a close eye on gas price signals and consider demand‑response or renewable PPAs to hedge against further intensity spikes.

What to do this week

• Review eligibility for the Boiler Upgrade Scheme and submit any pending applications before the end of the month.
• Assess whether your site is connected to a heat network that could qualify for HNES Round 13 and engage with the network operator.
• Analyse current gas contracts for exposure to price volatility; explore flexible or indexed tariffs where feasible.
• Prepare evidence for the Capacity Market hydrogen‑to‑power call if you have on‑site hydrogen generation or demand‑response capability.
• Monitor weekly road‑fuel price releases and evaluate short‑term fuel‑hedging options for fleet vehicles.

Bottom line

UK commercial energy buyers face a confluence of high carbon intensity, a gas‑heavy generation mix and tightening global oil markets. Policy levers – from boiler upgrades to hydrogen capacity – provide avenues to mitigate cost and emissions exposure, but timely engagement is essential. Aligning procurement strategies with the latest regulator signals and global market trends will be key to protecting margins and advancing sustainability goals.
