Charge, Bill & Collect

Chart Going Up

No more batch processing

Event driven and utilising the power of cloud technology, the billing engine calculates charges based on the latest available information as and when it is received, meaning no more batch processing ahead of a major bill run – from single-site fixed billing through to bespoke flex & pass-through products


Make a statement

All our statements are Ofgem compliant across all energy products, from fixed NHH through to HH Flex & Pass-through. For complex group hierarchies, ENSEK’s billing engine supports 1 to M parent to child relationships, and the ability to consolidate multiple MPANs and sites up to a single invoice with a bespoke bill format. Exceptions at site level do not impact the production of the overall group bill. Defined billing windows trigger automated prompts to the customer for meter reads (where applicable), with in-built read validation and exception tasks to manage out of tolerance customer reads. On production of the statement, a secure message is sent to the customer notifying them of the bill being available on their self-serve portal.

Hand For Product

Get paid

There are multiple pre-existing integrated payment solutions available through our partners, covering Direct Debit and Variable Direct Debit, as well as the capability to record and manage other non-standard payments such as BACS, Cheque, PayPal, and card. Our Direct Debit adequacy solution facilitates regular assessment of the Customer’s monthly Direct Debit payment against the view of customer and industry meter readings. Recommended increases/reductions in monthly payment values are scheduled as tasks allowing automated communication of low increases through fulfilment channels and outbound customer service contact on higher increases.
