• New Boiler Upgrade Scheme and Renewable Heat Incentive regulations supporting low‑carbon heat.
• Continued de‑commissioning of ageing fossil assets.

Headlines and what they mean

Great British Grid to speed up connections and cut bills

The government announced that the Great British Grid will fast‑track new connection applications, aiming to reduce waiting times by up to 30 % and lower network charges for large consumers. For commercial buyers this should translate into earlier access to renewable generation sites and modest reductions in transmission‑related costs, improving the economics of on‑site solar or wind projects. source

Boiler Upgrade Scheme Regulations: approved standards, grant categories and grant levels

The Boiler Upgrade Scheme (BUS) has published its final standards and grant tiers, covering high‑efficiency condensing boilers, heat pumps and hybrid systems. Eligible non‑domestic sites can claim up to £5,000 per installation, with higher subsidies for heat‑pump retrofits. This creates a clear pathway for finance directors to secure capital funding and meet sustainability targets while offsetting fuel‑price volatility. source

Guidance: Domestic and Non‑Domestic Renewable Heat Incentive Regulations: approved standards

The Renewable Heat Incentive (RHI) guidance now aligns with the latest efficiency criteria for biomass, solar thermal and ground‑source heat pumps. The revised tariff rates remain attractive for large‑scale installations, offering up to £0.12 per kWh of heat generated. Companies can lock in these rates for up to 20 years, providing long‑term cost certainty in a volatile energy market. source

UK’s de‑commissioning mission continues to expand

DESNZ highlighted an accelerated schedule for shutting down ageing coal and gas plants, adding 2 GW of capacity to the de‑commissioning pipeline this year. The move reduces future carbon liabilities for large users and signals a continued shift toward low‑carbon generation, reinforcing the importance of securing renewable PPAs now. source

Accredited official statistics: Energy prices: April to June 2027

The latest DESNZ price statistics show wholesale electricity prices averaging £85/MWh in the April‑June 2027 quarter, a 7 % rise on the previous period, driven by higher gas forward curves and tighter supply margins. The data underscores the need for hedging strategies and flexible demand‑side management to protect budgets. source

Geopolitics and global markets

Brent crude is trading above $120 a barrel, reflecting a tightening oil market after supply concerns in the Gulf and the Kremlin’s consolidation of power, which limits Russian export flexibility. The G7’s decision to release 100 million barrels of emergency stock aims to curb diesel shortages in Europe, but the move is modest relative to global demand. LNG shipments through the Strait of Hormuz have reached their highest level since the Iran‑Iraq war, indicating robust Asian demand and limited European alternatives. Meanwhile, U.S. oil drilling activity is inching up as prices fall, and U.S. natural gas production hit a record high in July 2026, adding modest upside to global gas supply. Europe’s soaring gas bills are pushing utilities back to coal, a trend that could increase wholesale price volatility for UK buyers. source, source, source, source, source, source

The view from the trade desk

The grid forecast shows a moderate carbon intensity of 100 gCO2/kWh, underpinned by a strong wind contribution of 44.2 % and a modest gas share of 22 %. With wind at near‑record levels, flexible demand‑side assets can capture low‑price periods, while the remaining gas and imports provide reliability. Traders are likely to price in a slight premium for firm capacity, but the overall mix supports competitive wholesale rates for customers who can shift load.

What to do this week

• Review upcoming connection applications and consider early engagement with the Great British Grid to lock in lower network charges.
• Assess eligibility for the Boiler Upgrade Scheme and Renewable Heat Incentive; model the impact of grant funding on CAPEX for heat‑pump projects.
• Re‑evaluate your hedging position in light of the latest wholesale price statistics (average £85/MWh) and consider adding short‑term contracts to cap exposure.
• Monitor global oil price movements, especially Brent above $120, and factor potential diesel cost spikes into logistics budgeting.
• Explore flexible demand‑side platforms that can respond to the forecast 100 gCO2/kWh intensity, leveraging wind‑rich periods for cost savings.

Bottom line

Regulatory actions are creating clearer pathways for low‑carbon investments, while the grid’s wind‑heavy mix and moderate carbon intensity offer a favourable backdrop for flexible procurement. However, tight global oil markets and rising European gas bills keep wholesale price risk elevated, making proactive hedging and demand‑side flexibility essential for UK commercial energy buyers this week.
