Is npower still an energy supplier?
Not for homes. E.ON bought npower in 2019 and moved every GB household customer to E.ON Next during 2020–2021. If you were with npower at home, your energy is supplied by E.ON Next today — the npower home brand no longer exists, and there is nothing you need to do unless you want a better rate.
The npower name does live on in one place: npower Business Solutions, which supplies larger organisations (broadly 10+ employees, over 100,000kWh electricity or 293,000kWh gas a year, or turnover above £2m). Smaller firms are pointed to E.ON Next. So “npower” today means business energy, not household energy.

About Npower in the UK
Npower was a well-known domestic energy supplier in Great Britain for many years. Following industry changes and the acquisition of innogy (Npower’s owner) by E.ON, Npower closed to new domestic customers and its household customers were moved to E.ON Next. This migration was largely completed by 2021, and Npower is now part of E.ON Next. Today, E.ON Next provides service, billing, and tariffs for former Npower household customers, while the Npower brand continues in the UK for business energy as Npower Business Solutions (part of E.ON).
Key points at a glance
- Npower no longer supplies domestic energy; customers were migrated to E.ON Next.
- Former Npower smart meters and billing accounts were moved to E.ON Next systems.

Smart meters and Npower/E.ON Next
Many former Npower homes had SMETS1 or SMETS2 smart meters. As part of the migration to E.ON Next, most meters continue to work normally and may be enrolled into the national smart network (DSMF/DCC) where applicable. If your in-home display or automatic readings stopped after migration, contact E.ON Next to re-pair or update your device.
- Automatic readings mean accurate bills with no manual meter submissions
- Smart prepayment options for top-ups without visiting a shop
- Compatibility varies—your supplier can confirm the status of your meter
Moving home from Npower to E.ON Next
If you were an Npower domestic customer and moved home, your account is now handled by E.ON Next. To avoid estimated bills:
- Take final meter readings on the day you move out
- Provide your forwarding address to settle your final bill
- At your new home, note the opening readings and the current supplier shown on the meter/bill
Then use EnergyPlus to compare and choose a new tariff for your new property.
Prepayment customers
Prepay customers formerly with Npower should now manage their top-ups and support via E.ON Next. Most key/card meters can be topped up at PayPoint or Payzone outlets; smart prepay users can top up online or via app depending on the supplier.
- Emergency credit and friendly hours may be available on smart prepay
- Keep your key/card safe and report faults promptly
- Switching from prepay to credit meter may be possible subject to checks
Exit fees, price cap and billing (July 2026 update)
Where the price cap stands now: the Ofgem cap for April–June 2026 is £1,641/yr for a typical dual-fuel Direct Debit home (electricity 24.67p/kWh + 57.21p/day standing charge; gas 5.74p/kWh + 29.09p/day). The current Ofgem cap is £1,663/yr (electricity ≈26.11p/kWh + 57.19p/day; gas ≈7.33p/kWh + 29.04p/day). Fixing now can shield you from the increase.
- Exit fees: If you’re on a fixed deal, leaving early may incur an exit fee. Variable tariffs typically have no exit fee.
- Ofgem price cap: The cap limits rates on standard variable tariffs in Great Britain and is reset quarterly. It does not cap your total bill—your usage still matters.
- Billing and payments: Direct Debit often offers the lowest rates; alternatives include pay-on-receipt or prepayment.
