Energy Markets Remain Reactive as Sentiment Shifts Day by Day
April 17, 2026
From April 2026, UK businesses will see a major increase in electricity network costs. TNUoS (Transmission Network Use of System) residual charges — the fixed part of your bill — are set to almost double in a single year.
What does this mean?
- These charges are fixed daily costs per site, not linked to usage
- So even if you reduce consumption, you’ll still pay more
- Many contracts treat TNUoS as a pass-through cost, meaning increases can hit mid-contract
Why is this happening?
The UK grid is undergoing a huge upgrade to support net zero — including connecting renewable energy and strengthening infrastructure. This requires billions in investment, which is now being recovered through these charges.
The impact…
- Standing charges will become a bigger part of your energy bill
- Some businesses could see significant cost increases regardless of usage
- Regional differences and capacity bands will affect how much you pay
What should you do now?
✔ Review your energy contracts (especially pass-through terms)
✔ Check your capacity and banding
✔ Update budgets ahead of April 2026
This isn’t a small adjustment — it’s a structural shift in how energy costs are applied.
