UK Energy Market Report — 1 November 2026

What we’re watching today

• Green light for a new undersea interconnector boosting import capacity.
• SSES tariff interoperability code changes enabling broader demand‑response participation.
• UK ETS allocation updates and opt‑out guidance for hospitals and small emitters.

Headlines and what they mean

Major undersea power cable given green light

The Department for Energy Security and Net Zero approved a major undersea cable, expanding cross‑border capacity and providing a new source of low‑carbon electricity for the UK grid. For commercial buyers, this could translate into greater supply resilience and potential price moderation as import options increase. source

Smart Secure Electricity Systems (SSES) tariff interoperability: code modifications for Phase 1a

DESNZ published code modifications that advance Phase 1a of the SSES tariff interoperability framework. The changes simplify the integration of flexible tariffs across multiple suppliers, unlocking more granular demand‑response opportunities for large energy users. Companies with smart‑metered assets can now negotiate more competitive, time‑of‑use contracts. source

UK ETS Allocation Table for operators of installations

The latest UK Emissions Trading Scheme allocation table outlines free allowances for industrial installations. Understanding the allocation is crucial for budgeting carbon costs, especially for facilities with significant gas‑fired generation. Firms should assess whether their current allowance levels align with projected emissions and consider flex‑management strategies to mitigate exposure. source

UK ETS: Hospital and Small Emitter status

Guidance confirming the opt‑out criteria for hospitals and small emitters clarifies eligibility for exemption from the ETS. While most commercial buyers are not directly affected, the policy signals a broader regulatory focus on sector‑specific carbon pricing, which may influence future compliance obligations for ancillary services and supply chains. source

Boiler Upgrade Scheme statistics: September 2026

Recent statistics show the uptake of the Boiler Upgrade Scheme, highlighting continued investment in high‑efficiency heating for commercial premises. The data underscores the market’s move toward decarbonising heat, offering opportunities for buyers to negotiate better rates on upgraded boiler contracts and to claim sustainability credits. source

Geopolitics and global markets

Oil prices are edging toward $120 a barrel, driven by tightening supplies and speculative positioning, which raises wholesale electricity costs linked to oil‑fired generation and fuels price expectations. source The United States’ LNG boom faces its biggest test as export volumes confront competitive pressures from Europe’s expanding import capacity, potentially influencing spot LNG prices that feed into UK gas contracts. source Meanwhile, Europe is seriously reconsidering its oil refinery phase‑down, a move that could tighten regional fuel markets and affect diesel and heating oil availability for UK importers. source

The view from the trade desk

The grid forecast shows a high carbon intensity of 170 gCO2/kWh, with gas supplying 39.2 % of generation. The continued reliance on gas, combined with a modest wind contribution (15.3 %), suggests that price signals will stay sensitive to gas market dynamics. The new undersea cable and SSES tariff changes provide avenues to dilute this exposure through imported low‑carbon power and flexible demand, aligning with TUS’s 150 + GWh flex‑management portfolio that delivers >20 % savings versus typical supplier projections.

What to do this week

• Review your tariff contracts for eligibility to participate in the SSES Phase 1a demand‑response scheme.
• Model the impact of the upcoming undersea interconnector on your import‑price assumptions.
• Align your carbon budgeting with the latest UK ETS allocation table and explore flex‑management to offset potential allowance shortfalls.
• Consider upgrading heating assets under the Boiler Upgrade Scheme to capture efficiency gains and sustainability credits.
• Monitor Brent crude movements and US LNG export trends for early signals on wholesale price volatility.

Bottom line

Regulatory progress on interconnectors and tariff interoperability, together with evolving ETS allocations, equips commercial buyers with tools to manage cost and carbon risk. However, global oil price pressures and a still‑gas‑heavy generation mix keep wholesale electricity prices vulnerable. Leveraging flexible demand, imported low‑carbon power and efficiency upgrades will be key to preserving margins in the coming weeks.
