Wokingham Borough residents should have received a letter asking them to check that the details of those registered to vote at their address are correct.
Residents must respond, even if there are no changes to be reported.
Andrew Moulton, Wokingham Borough Council’s electoral registration officer, said: “We encourage you to respond to the forms as soon as possible.
“By doing so we can limit the resources needed to chase up properties that don’t respond, which is a waste of public funds.
“It’s especially important that you check your details are correct if you have moved recently.”
