The deadline to register is 11.59pm on Monday 20 April. Anyone not registered by then will be unable to take part in the vote.
The elections will determine who controls Swindon Borough Council for the next 4 years, which is responsible for decisions that directly affect people living in the town.
Those decisions include council tax levels, housing and planning applications, regeneration of the town centre, road maintenance and infrastructure, and social care services.
The Electoral Commission is warning that younger people, renters and those who move home frequently are less likely to be registered.
In a town such as Swindon, where the population is growing and many residents move regularly, this can have a significant impact on who is represented at a local level.
Turnout in local elections is typically lower than at general elections. As a result, relatively small numbers of voters can determine who takes control of the council.
Anyone aged 16 or over can register to vote, although you must be 18 to cast a vote.
Residents who have recently moved house must register again at their new address. Failing to update details is a common reason people are unable to vote.
Voters will also need to show photo identification when voting in person.
Those without an accepted form of ID can apply for free voter identification. The deadline to apply is 5pm on 28 April.
The deadline to apply for a postal vote is 21 April, while applications for a proxy vote must be submitted by 28 April.
Residents can register to vote online.
With key decisions about Swindon’s future set to be made, officials are encouraging anyone who wants a say to ensure they are registered before the deadline.
