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’s domestic customers were moved to E.ON Next. This migration was largely completed by 2021. 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).

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
- 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. 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.
For the latest cap level and guidance, see Ofgem: ofgem.gov.uk/energy-price-cap.
Help, support and schemes
- Warm Home Discount: Eligible households may receive a one-off annual rebate. Scheme rules and participating suppliers are set by government and Ofgem. Check current eligibility on GOV.UK.
- Priority Services Register: Free support for customers in vulnerable situations (health, disability, pensionable age, etc.). Contact your supplier to join.
- Energy efficiency: Reducing usage can lower bills—smart meters and advice can help identify savings.
