Over one million people registered to vote, 820,000 of them online, since the new online platform went live in June - equivalent to almost two percent of the voting population - according to the Cabinet Office.
Official statistics show that 94 percent of voter registration applications are now filled in online and there is a 93 percent satisfaction rate with the service.
The service is accessible from any device and roughly a third of people using it have accessed the site through a smartphone or tablet.
The online tool allows you to register in under five minutes by providing your name, address, date of birth and National Insurance number.
The voting registration service was developed by the Government Digital Service (GDS) and is one of 25 ‘exemplar’ services, four of which are now fully up and running.
Online electoral registration is part of wider plans to move to individual electoral registration (IER) instead of the existing ‘head of household system’ whereby one person provides the details of all the people living at the same address.
The government hopes that moving to IER will reduce fraud and errors and give people greater control and ownership over their registration.
The Cabinet Office’s constitution minister Sam Gymiah said: “We designed this new online service with the user in mind, and it’s great that such a large number of people across the UK are using the service and responding well to our improvements.
“We’ve made registering to vote easier than ever before and it’s really positive that nearly a quarter of those registering in the last month have been under the age of 35. But we know there’s more to do to maximise registration rates, so we will continue our efforts to ensure that everybody has their say in the how the country is run.”
