Headlines and what they mean

Capacity Market: changes for Prequalification 2027

The Department for Energy Security and Net Zero (DESNZ) has published a consultation on how capacity providers will be pre‑qualified for the 2027 auction. The changes tighten eligibility criteria, introduce a stronger focus on reliability metrics and raise the bar for financial resilience. For commercial buyers, this means that contracts secured now may need to be reassessed against the new rules, and early engagement with providers that can demonstrate compliance will be crucial to avoid supply gaps.

Capacity Market: new technologies 2026

A parallel DESNZ consultation expands the list of technologies that can compete in the Capacity Market, adding advanced battery storage, demand‑side response platforms and hydrogen‑based generation. This opens a pathway for businesses that have invested in flexible assets or are considering green‑hydrogen projects to access capacity payments, potentially offsetting capital costs and improving the economics of decarbonisation.

Energy Savings Opportunity Scheme (ESOS): find out if you qualify and how to comply

DESNZ has refreshed guidance on ESOS, clarifying the qualifying turnover threshold and the methodology for identifying energy‑saving measures. The deadline for submitting compliance evidence is approaching, and non‑compliance can trigger enforcement action and reputational risk. Companies should audit their energy data, prioritise low‑cost efficiency projects and consider using TUS’s flex‑management platform to demonstrate measurable savings.

Notice: Non‑domestic smart meters – energy supplier obligations

New obligations require energy suppliers to ensure that all non‑domestic customers are offered smart‑meter installations by the end of 2025. Suppliers must provide clear information on tariff options and data‑sharing arrangements. For large energy users, this creates an opportunity to negotiate more granular consumption data, but also a risk of tariff changes if suppliers pass on upgrade costs.

Non‑domestic smart meter rollout post‑2025

The rollout consultation outlines the phased approach for installing smart meters in commercial and public sector premises after 2025. It stresses interoperability standards and data security, which will affect how businesses integrate meter data into their energy management systems. Early participation in pilot schemes can give firms a head‑start on leveraging real‑time data for demand optimisation.

Notice: Green Gas Support Scheme (GGSS) – expenditure forecast statements and tariff change notices

DESNZ has released the latest GGSS tariff change notices, indicating a modest uplift in the support price for renewable gas certificates. This will raise the cost of green gas contracts marginally but also strengthens the market signal for renewable gas production. Buyers with long‑term green‑gas contracts should review the impact on their carbon‑intensity targets and consider hedging strategies.

Notice: UK ETS Allocation Table for operators of installations

The updated allocation table details the free allowance allocations for 2027, with a steeper phase‑down for high‑emitting sectors. Companies operating large installations must reassess their allowance needs and explore internal carbon pricing or offset purchases to stay within compliance.

Correspondence: Oil and gas – OPRED communications, 2026

DESNZ’s OPRED (Oil and Gas Production and Exploration Data) communications outline new reporting requirements for offshore production volumes and emissions. While primarily aimed at upstream operators, the data will feed into the UK ETS and could influence downstream gas pricing, affecting commercial buyers with significant gas exposure.

Geopolitics and global markets

Global oil markets remain volatile. An oil‑price shock has driven UK borrowing costs higher, tightening financing conditions for energy projects (source). At the same time, record‑high oil prices are accelerating China’s shift away from crude imports, reducing Asian demand and supporting European price stability (source). Russia’s oil revenue has fallen sharply as Urals prices slipped to $59, limiting Russian export capacity and easing pressure on European supply (source). The EU’s tougher measures against Russia after a drone attack in Leipzig add further geopolitical risk to the market (source). Meanwhile, US LNG exports have risen 23% in H1 2026, expanding global LNG availability and tempering European gas price spikes (source). These dynamics collectively push UK wholesale electricity and gas prices higher, reinforcing the need for hedging and flexible procurement.

The view from the trade desk

The grid forecast shows a carbon intensity of 76 gCO₂/kWh, classified as moderate. Wind now supplies 52.5% of generation, nuclear 19.3%, gas 14.8% and biomass 13.3%, with coal and imports at zero. The strong wind contribution keeps intensity low, but the gas share remains a lever for price volatility, especially given the global oil‑price shock. Buyers should monitor real‑time generation data to optimise demand when wind output peaks.

What to do this week

• Review your capacity contracts against the upcoming 2027 pre‑qualification rules and engage providers that meet the new reliability standards.
• Conduct an ESOS readiness check; prioritize quick‑win measures and capture data to demonstrate compliance.
• Assess the impact of the GGSS tariff uplift on your green‑gas procurement and consider short‑term hedges.
• Prepare for the non‑domestic smart‑meter rollout by mapping existing metering infrastructure and identifying integration points for energy‑management platforms.
• Evaluate exposure to UK ETS allowance price changes and explore internal carbon‑pricing mechanisms.

Bottom line

UK commercial energy buyers face a confluence of regulatory tightening and global market stress. The Capacity Market reforms and expanded technology eligibility reshape long‑term procurement, while immediate compliance obligations around ESOS, smart meters and green‑gas tariffs demand swift action. Coupled with higher oil‑price‑driven borrowing costs and a surge in US LNG exports, the environment calls for proactive risk management, data‑driven optimisation and strategic use of flex‑management tools to protect cost and sustainability targets.
