The annual canvass has been brought forward by the Government to ensure that the registers used for the November 15 elections are as up to date as possible.
Cheshire West and Chester Council is responsible for conducting the annual canvass and maintaining the register of electors.
From next week, around 147,000 forms will be dropping through letterboxes across the Borough to make sure that everyone who is entitled to vote is registered.
Each of the 41 police force areas in England and Wales will directly elect a Commissioner, who will work with the public, the police and local partners to ensure effective policing.
Council Chief Executive Steve Robinson said: “The annual canvass usually begins in September, but this year it has been brought forward to ensure it is completed ahead of the PCC elections.
“Registering is a simple process. However, some people may not realise that they must register every year, even if their details have not changed.
“Do not assume that you are registered to vote because you pay Council Tax.”
The annual canvass gathers the details of all eligible residents aged over 18, or who will be 18 in the next 12 months.
Each form is printed with the names of people listed as living at that address. If no changes are required, the details simply need to be confirmed by text, freephone or email.
If any information needs updating then residents should return their form by post in the enclosed pre-paid envelope.
Guidance on how to complete the form is printed on the reverse side. A helpline is available for anyone requiring further assistance.
