How to read your business energy bill

How to read your business gas and electricity bills

We know that time is precious when you’re running a business so we’ve designed your business gas and electricity bills to be easy to read and straight to the point.

When you receive a gas or electricity bill in the post from npower, you’ll see it’s made up of:

  • an energy statement at the front
  • an invoice overleaf

Understanding your energy statement open/close

The first page you’ll see is your energy statement which features a summary of how much you owe across various accounts. It shows the balance brought forward from your last statement - minus any payments we’ve received from you, - the charges incurred since your last invoice, any cancelled invoices and the total amount due for payment.

If you don’t already pay by Direct Debit you’ll also find a Giroslip at the bottom of your energy statement.

Your energy statement features some useful information you might like to keep handy:

  • The supply address – the address where you use the electricity or gas
  • Your account number – you’ll need to quote this when you contact us
  • Our phone number – for quick reference if you need to call with a query
  • Loss of supply number – this is the number to call in an emergency or if you have a problem with supply
  • Information regarding our Dispute/Complaints Process

Important numbers open/close

Your loss of supply number is a 21 digit number on our bill. It usually starts with an ‘S’ and it should be in a table or in a row. You’ll need it handy if you lose power or there’s a gas leak. It’s also known as your MPAN (Meter Point Administration Number) on your electricity bill, or your MPRN (Meter Point Reference Number) on your gas bill.

What the numbers mean open/close

Your invoice shows the opening and closing meter readings and the number of units for which you’ll be charged.. An ‘E’ next to the reading shows it’s an estimated reading, while a ‘C’ shows it’s a reading supplied by you, the customer.

Please note: this is the page to keep for your VAT records.

Understanding your electricity invoice open/close

On your electricity invoice you’ll find detailed information about your meters, meter readings and the amount of electricity used. If your business has more than one meter, each meter will be listed. And if you have more than one business site we’ll give you a separate invoice for each location.

Extra charges on your business’s bill open/close

You may also see VAT, Climate Change Levy (CCL), Renewables Obligation (RO) or Green Deal charges on your bill.

VAT open/close

Gas and electricity supplied to a business are subject to the standard rate of VAT (unless your business qualifies for a reduced rate). For more information on VAT and whether your business qualifies for a reduced VAT rate contact the HM Revenue and Customs VAT helpline on 0300 200 3700 or visit hmrc.gov.uk/business.

If your business does qualify for a reduced VAT rate, fill in our VAT declaration form and either email or post it to us. We’ll make sure the reduced rate is applied to your bill.

Climate Change Levy (CCL) open/close

CCL applies to all businesses paying the standard rate of VAT. Find out more about CCL and how it applies to your business.

Renewables Obligation (RO) open/close

RO is a government incentive that encourages the use of renewable power. For customers on newer tariffs it’s usually wrapped up in basic charges. But if you’re on older plan it might well be listed separately. Read more about RO.

Green Deal open/close

If you’ve moved into premises with a Green Deal or taken out a Green Deal plan yourself to improve energy efficiency, charges will be added to your bill. Our customer services team can help if you have any questions about these charges.
