UK Energy Market Report — 22 October 2026

What we’re watching today

• UK ETS policy rollout and guidance – compliance and carbon‑cost implications.
• Hornsea 3 offshore transmission OFTO tender – potential new offshore wind capacity.
• Jackdaw gas field approval and broader North Sea gas developments.
• Boiler Upgrade Scheme grant levels – low‑carbon heating incentives.
• Consultation on Clean Heat Market Mechanism revisions for 2027/28.

Headlines and what they mean

DESNZ publishes policy overview of the UK Emissions Trading Scheme

The Department for Energy Security and Net Zero released a comprehensive policy paper outlining the UK ETS framework, including cap trajectories and allocation rules. For commercial buyers, the paper signals a more predictable carbon price path and highlights the need to integrate ETS exposure into budgeting and procurement strategies. source

DESNZ issues guidance on participating in UK ETS markets

A companion guidance note details how firms can register, trade allowances and access the market platform. It clarifies reporting obligations and the timing of allowance surrender, reducing administrative uncertainty. Energy‑intensive companies should review the guidance now to ensure they are set up before the next compliance window. source

Ofgem launches £3.5 bn Hornsea 3 offshore transmission OFTO tender

Ofgem announced the biggest ever offshore transmission tender, targeting the Hornsea 3 link that will connect a new 2.6 GW wind farm to the grid. Successful bidders will secure long‑term revenue streams from transmission services. The tender expands offshore wind capacity and could create PPAs for corporates seeking renewable contracts at scale. source

Jackdaw gas field receives development approval

The Jackdaw field in the southern North Sea has been granted development consent, adding roughly 0.5 bcm of gas per year to UK supply. While the field is modest, it reinforces domestic production at a time when European gas inventories are tightening, offering a modest hedge against import price spikes. source

Boiler Upgrade Scheme regulations set grant levels for low‑carbon heating

The latest Boiler Upgrade Scheme regulations publish approved standards, grant categories and funding thresholds for heat‑pump and biomass boiler replacements. Eligible businesses can claim up to £5,000 per unit, accelerating decarbonisation of site heating and reducing operating costs. Early application is advised as funding caps are approached. source

Consultation on Clean Heat Market Mechanism revisions ahead of 2027/28

DESNZ opened a consultation on proposed changes to the Clean Heat Market Mechanism, aiming to increase support for renewable heat technologies and tighten eligibility criteria. The revisions could affect the economics of large‑scale heat projects slated for 2028, so firms planning new heat infrastructure should monitor the outcome. source

Geopolitics and global markets

Saudi Arabia’s crude output has fallen to a record low while exports are at a five‑month high, tightening global supply and supporting higher oil prices source. Simultaneously, heightened tensions in the Hormuz Strait raise the risk of a broader energy‑related food crisis, adding a geopolitical premium to oil and gas markets source. In the UK, the recent approval of a major North Sea gas field underscores a domestic supply boost amid these external pressures source. Finally, BP’s exit from the North Sea and the subsequent acquisition of assets by independents could reshape the supply landscape, potentially affecting future gas pricing and contract availability source.

The view from the trade desk

The grid is forecast to run at a low carbon intensity of 67 gCO₂/kWh, driven by a wind share of 53.7% and nuclear at 18.8%. Gas and imports together account for just under 21% of generation, limiting exposure to volatile gas prices. This mix supports a favourable environment for renewable PPAs and reinforces the value of low‑carbon hedging strategies.

What to do this week

• Review your UK ETS exposure and consider forward‑contracting allowances or carbon‑offset purchases.
• Confirm eligibility for the Boiler Upgrade Scheme and begin the grant application process.
• Track the Hornsea 3 OFTO tender outcome; early engagement could secure renewable electricity contracts.
• Model the impact of the Jackdaw field on your gas price forecasts and adjust procurement plans accordingly.
• Begin scenario planning for the Clean Heat Market Mechanism revisions to protect upcoming heat‑project economics.

Bottom line

Regulatory momentum on carbon pricing, offshore wind transmission and low‑carbon heating is creating both compliance obligations and opportunity windows for UK businesses. Coupled with a low‑carbon grid mix and a backdrop of tight global oil markets, the next week is pivotal for firms to lock in price certainty, tap available grants and position themselves for the expanding offshore wind supply chain.
