Electoral registration & electoral management system

Eros is a modern, Windows-based system which is widely seen as the solution best enabling customers to save cost by working creatively and efficiently. Eros is used by the by the five largest registration authorities in the UK - Northern Ireland, Birmingham, Lothian and Lanarkshire VJBs and Leeds.

We ensured IER changes to Eros were in close association with our customers and the Cabinet Office. We continue to work closely with our customers to ensure we are constantly refining and evolving our electoral management system with new IER design implemented in key areas to enable our customers with higher accuracy, reliability and efficiency.

We are continually refining Eros, to make sure the system is as efficient and usable as possible for our customers. For example, Eros can be configured so that all elector and house transitions and processes that can be automated are. This means if no human decision is required, the system will function automatically, freeing your expertise for where it really matters.

Eros doesn’t simply comply with legislative requirements; it has been developed to give you additional functionality that allows you to manage your register in the way that suits you best. This includes the following key benefits;

  • ‘Data-driven state engine’ ensures that all transactions align with legislation and Electoral Commission Guidance and won’t allow you to process a change that goes against the law whilst still giving you the flexibility you need
  • Workflow screens provide simple, at-a-glance, views of complex procedures that give you actionable insights into your data and enable you to make intelligent decisions
  • Powerful marshalling screens allow you to slice, filter, group and sort data during processing, ensuring accuracy to make better decisions more efficiently
  • Our in-built document scanning module caters for the new style registration forms and household enquiry forms. The system intuitively understands the forms you are scanning and deals with them as appropriate
  • Drag and drop functionality allows you to deal with electors individually or in bulk
  • The ability to export data as a custom report from any of the key marshalling screens within Eros which is ideal for performing pre-export checks or for retaining for audit purposes
  • Intuitive screens for matching downloads of electors who have applied at the IERDS – minimising the scope for any duplicate entries to be added to the electoral register
  • The ability to send emails to new potential electors to encourage them to register online – saving you time, printing and postage costs
  • Extensive suite of statistical information on a range of IER-related areas

In addition to the enhanced user experience and back-end resilience, Eros has been updated to automate as many of the IER processes as possible to save you even more time and money. These include:

  • Ability to import lists of houses that are empty on Council Tax data, compare the number of registered electors in Eros and automatically update the HEF response field in bulk
  • Absence of a potential elector on a no-change HEF batch will automatically add a piece of removal evidence against the elector
  • HEFs returned as undeliverable by your postal carrier will automatically result in a piece of removal evidence being added to each elector in the household upon scanning
  • Potential fraudulent activity is automatically identified for further investigation
  • Automated and configurable transitions for electors and houses that will automatically move both through each ITR/HEF status
  • Automatic generation of acknowledgment and confirmation letters once new electors are added
  • Automatic production of corresponding canvasser registers when HEFs and ITRs are produced which have been flagged as requiring a personal visit
