⚡ Npower to Exit Electricity Supply Market on 1 August 2025: What Customers Need to Know

Npower is voluntarily exiting the electricity market on 1 August 2025 — here’s what it means for your contract, supply, and next steps.

📢 What’s Happening with Npower?

The energy regulator Ofgem has confirmed that Npower Limited will no longer hold an electricity supply licence from 1 August 2025.

This wasn’t a forced revocation — Npower voluntarily asked for its licence to be revoked back in March 2025, and Ofgem has agreed.



So from 1 August 2025, Npower will no longer be legally allowed to supply electricity to customers.

❓Why Did Npower Give Up Its Licence?

This move is part of Npower’s long-running exit from the UK domestic and SME supply market. Most of its customer base has already been transferred to E.ON Next, following Npower’s earlier restructuring. This latest licence revocation is effectively the final step in that process.

❓What Does This Mean for Npower Customers?

Most Npower customers were previously transferred to E.ON Next as part of a market exit restructure. But if you’re still seeing Npower on your bills or unsure who your current supplier is, now is a good time to check.



If any customers remain directly supplied by Npower at the time of revocation, Ofgem may step in and trigger a "Supplier of Last Resort" (SoLR) process to protect them. This ensures continued supply and typically protects credit balances — but only in specific circumstances.

⚠️ Can You Switch Supplier?

Only if your existing supplier cannot meet the rates and terms agreed in your current contract — for example, if:

• Your fixed rates can no longer be honoured
• The supplier cannot maintain service under your T&Cs
• You are moved under SoLR arrangements with new terms



So you can’t automatically leave just because Npower’s licence ends — it depends on whether your supply is transferred, honoured, or disrupted.

🧾 What Should You Do Now?

If you think you may still be linked to a legacy Npower contract, we recommend:

• 📩 Checking your latest bill or email correspondence to confirm who your active supplier is.

• 🧾 Noting your MPAN number (from your bill or meter) — we can use it to help identify your current supplier.

• 📞 Avoiding any rush to switch until more is confirmed — especially if a SoLR process is triggered.

🕵️‍♂️ More Details to Follow

Ofgem hasn’t yet confirmed if any SoLR appointments will be needed, and further guidance is expected before 1 August 2025.

Final Thoughts

Npower’s licence revocation is a technical formality — but it could affect you if you’re still linked to an old Npower contract.


Whether a SoLR process is triggered or not, understanding your current energy position is the best first step.
