Canterbury City Council has sent voter registration forms to every household in the district.
People need to be registered in order to vote, with the next scheduled election being the one to Canterbury City Council in May next year.
The authority is urging people to read the forms carefully before filling them in.
For all those people who do not reply, the council is required by law to send two reminder letters followed by a visit to the property in order to collect the necessary information.
Last year this cost local taxpayers £20,000.
Electoral registration officer Colin Carmichael, the chief executive of Canterbury City, said: “It is important to make sure you are registered to vote.
“If you are not, you will not be able to vote at forthcoming elections and it could put your credit rating at risk, which means you may find it difficult to get a loan or mortgage.
“Please help us to keep our costs down by replying to the form as quickly as possible. This will remove the need to send reminders or organise a visit.”
Next year’s council election is expected to be one of the most hotly contested in recent times – especially in light of the parliamentary election victory of Labour’s Rosie Duffield in June last year, ending Conservative domination of the Canterbury and Whitstable constituency.
There are 39 council seats available. Currently, the Conservatives hold 29, Labour four, the Lib Dems three and there are three independents.
The quickest and easiest way to complete the form is via the specific page on the council’s website.
Other options are available for people who are not online and information about this is on the form.
