ista Energy Solutions are not your energy supplier, we simply provide billing services on behalf of your supplier. As a company, ista provides billing for approximately 13 million customers using 48 million meters.
As part of our commitment to high quality customer service, we promise to ensure:
- Accurate and clear billing
- Efficient resolution of queries
- Flexible payment options
- Positive communication
We collect consumption data from your energy meters and generate accurate bills for all our customers. Our billing system has been developed and tested regularly over the past 15 years.
Although we bill some customers quarterly, our invoices will usually be generated monthly and will be delivered electronically or by post, depending on your preferences.
Bills are calculated by applying the current tariff to the amount of energy used, including any standing charges. Bills will include, but are not limited to:
- Customer name and address
- Bill number and bill date
- Current and previous meter reading
- Energy use since previous bill
- Comparison of energy use for property type against historical usage
- Current tariff and charges
- Amount due including a VAT statement
- How to pay and contact for payment difficulties
- Customer services information
- Emergency contact details
