• Clean Heat Market Mechanism revisions – upcoming changes for commercial heating contracts.
• Green Gas Support Scheme budget – funding outlook for biomethane projects.

Headlines and what they mean

Road fuel prices: 19 October 2026

The Department for Energy Security and Net Zero published the latest official road fuel price statistics, showing a modest rise in petrol and diesel rates over the past week. Higher pump prices directly increase operating costs for vehicle‑heavy businesses and may prompt a review of fuel‑efficiency measures or a shift to alternative fuels. source

Clean Heat Market Mechanism: revisions ahead of the 2027/28 scheme year

DESNZ has opened a consultation on the next iteration of the Clean Heat Market Mechanism, which subsidises low‑carbon heating solutions for commercial and public‑sector sites. The proposed changes could tighten eligibility criteria and adjust subsidy levels, meaning businesses planning new heat‑pump or biomass projects should monitor the outcome closely to secure funding before the 2027/28 rollout. source

Green Gas Support Scheme: budget management

A recent notice details the current budget position of the Green Gas Support Scheme (GGSS). With the scheme’s allocation nearing its limit, applicants for biomethane projects may face tighter funding windows. Companies should accelerate project timelines and ensure all eligibility documentation is in order to capture remaining support. source

Stronger protections for heating oil customers

DESNZ announced new consumer‑protection measures for heating oil users, including clearer pricing disclosures and a cap on sudden price hikes. While primarily aimed at residential customers, the rules also affect commercial landlords and facilities that rely on oil‑fired boilers, offering greater price certainty and a framework for dispute resolution. source

Guidance: Contracts for Difference, renewables obligation and small‑scale feed‑in tariffs – exemptions and compensation

The latest guidance lists companies that have been awarded exemptions or compensation under the CfD, RO and FIT schemes. This signals the regulator’s ongoing effort to address cost overruns in renewable projects, which may influence future pricing of renewable electricity contracts that commercial buyers negotiate. source

Geopolitics and global markets

Brent crude breached the $110 per barrel mark after a series of tanker attacks in the Persian Gulf raised concerns over supply disruptions, pushing oil‑linked fuel prices higher across Europe. The same volatility feeds into the UK’s wholesale power market, where higher oil prices can lift generation costs for gas‑fired plants. Separately, a report highlighted that the UK is paying record sums to balance the grid as transmission constraints lag behind generation growth, underscoring the importance of flexible demand‑side solutions and interconnection upgrades. source source

The view from the trade desk

The grid carbon intensity forecast sits at 99 gCO2/kWh, reflecting a moderate mix with wind now providing 44% of generation, gas 21.9%, nuclear 16% and biomass 10.1%. The strong wind contribution keeps emissions low, but the reliance on gas and imports (7.9%) means price signals remain sensitive to wholesale gas markets and any supply shocks. Buyers should watch for any sudden shifts in wind output that could tighten the market.

What to do this week

• Review fleet fuel budgets against the latest road fuel price data and consider short‑term hedging or a transition to low‑carbon fuels.
• Assess the impact of the Clean Heat Market Mechanism consultation on any planned heat‑pump or biomass projects and prepare comments where appropriate.
• Verify eligibility for the Green Gas Support Scheme and submit any pending applications before the budget is exhausted.
• Update heating oil contracts to reflect the new consumer‑protection rules and explore alternative heating options where feasible.
• Incorporate the current carbon intensity forecast into your internal emissions reporting and consider flexible demand‑side measures to mitigate potential price spikes.

Bottom line

UK commercial energy buyers face a mixed landscape: rising road fuel costs and tighter heating‑fuel regulations increase near‑term expense pressures, while a strong wind‑driven generation mix keeps carbon intensity low. Global oil market turbulence adds further uncertainty, making proactive risk management and early engagement with upcoming policy consultations essential for cost control and sustainability targets.
