UK Energy Market Report — 15 October 2026

What we’re watching today

• Low‑carbon generation mix keeps grid carbon intensity at 67 gCO2/kWh.
• DESNZ’s new heating‑oil consumer protections and Clean Heat Market Mechanism revisions.
• Ofgem’s draft cost assessments for Dogger Bank A and Moray West offshore wind transmission assets.

Headlines and what they mean

Building an energy system that delivers for all

DESNZ outlined a long‑term vision for a resilient, low‑carbon system, emphasising expanded offshore wind, CCUS and flexible demand. The speech signals continued policy support for projects that can provide firm capacity, which may unlock further investment opportunities for large energy users seeking reliability and decarbonisation pathways. source

Stronger protections for heating oil customers

A new statutory framework will tighten price‑cap enforcement and improve transparency for heating‑oil suppliers. Business sites that still rely on oil‑fired boilers can expect greater price stability and clearer redress mechanisms, reducing budgeting uncertainty. source

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

DESNZ published consultation papers proposing higher subsidy rates for high‑efficiency heat pumps and biomass boilers, alongside stricter eligibility criteria. Early engagement will be crucial for firms planning to transition heating systems, as the revised mechanism could affect capital budgeting and eligibility for support. source

Energy Consumer Satisfaction Survey: July‑August 2026 summary

Ofgem’s latest consumer‑satisfaction data shows modest improvements in billing clarity but persistent concerns over price volatility. The findings suggest that suppliers are still struggling to communicate cost drivers, reinforcing the need for commercial buyers to negotiate transparent contracts and consider flexible pricing arrangements. source

Consumer impacts of market conditions survey: February‑March 2026

The survey highlights that 42 % of respondents felt their energy bills were unaffordable, with small‑ and medium‑size enterprises most affected. This underscores the importance of demand‑side management and hedging strategies to mitigate exposure to market spikes. source

Offshore transmission: draft cost assessment for the Dogger Bank A (DBA) Offshore Windfarm Transmission Assets

Ofgem released a draft cost assessment for the transmission infrastructure of the Dogger Bank A project, estimating £X billion in capital expenditure. The assessment will shape the final revenue model for the offshore wind farm, influencing power purchase agreement pricing for downstream users. source

Offshore transmission: draft cost assessment for the Moray West Offshore Wind Farm

Similarly, a draft cost assessment for Moray West’s transmission assets was published, signalling potential cost recovery through the transmission tariff. Early awareness allows large energy consumers to anticipate the impact on wholesale power prices as the projects move toward commissioning. source

Geopolitics and global markets

Oil prices slipped after US President Trump signalled a possible easing of sanctions on shadow‑fleet tankers, easing short‑term pressure on diesel and jet fuel costs but leaving uncertainty over longer‑term supply dynamics. At the same time, tanker attacks in the Gulf of Oman and a sharp drawdown in US crude inventories have tightened the global oil market, supporting a rebound in crude prices. A newly announced $80 billion Taiwan LNG deal adds demand pressure on global LNG supplies, which could translate into higher spot gas prices for Europe. Finally, the pending decision on a £47 billion North Sea oil development highlights the UK’s continued reliance on domestic hydrocarbons, a factor that may influence future gas‑on‑power pricing. source source source source

The view from the trade desk

The grid forecast shows a low carbon intensity of 67 gCO2/kWh, driven by a wind share of 58.7 % and nuclear at 14.6 %. Gas generation remains at 14.5 %, providing firm capacity while the market watches offshore wind transmission cost outcomes. With wind dominance, price volatility is likely to be linked to weather patterns and any unexpected curtailment, making demand‑side flexibility a valuable hedge.

What to do this week

• Review heating‑oil contracts in light of the new consumer‑protection framework and consider switching to lower‑carbon alternatives where feasible.
• Engage early with DESNZ on the Clean Heat Market Mechanism consultation to shape future subsidy eligibility for heat‑pump projects.
• Analyse the draft offshore transmission cost assessments for Dogger Bank A and Moray West to anticipate potential impacts on power purchase agreement pricing.
• Strengthen demand‑side management programmes to mitigate exposure to any short‑term oil price rebounds from global market tightening.
• Monitor the Taiwan LNG deal and North Sea oil decision for signals on future gas price trajectories.

Bottom line

UK commercial energy buyers face a mixed landscape: a low‑carbon, wind‑rich grid keeps carbon intensity at historic lows, but regulatory shifts in heating oil and offshore wind transmission costs, combined with volatile global oil and LNG markets, introduce pricing uncertainty. Proactive engagement with policy consultations, contract reviews and flexibility measures will be key to managing risk and capitalising on the low‑carbon supply mix.
