The redesign is intended to make it easier for residents to interact with the council and find out more about its after-hours services.
Terry Hall, the town council's public information officer, said, "The previous website had been informative and achieved a high standard of service.
"But a brand new look, more content and improved navigational structure will now make it even easier to find out about Hailsham Town Council and its services outside of office hours.
"The enhanced website provides a clearer structure, simplified navigation and added interactive functions.
"Residents and visitors will now be able to take part in polls, surveys and quizzes, share their own reviews and provide feedback on not only the website's usability, but also town council services in general.
"Additionally, the site will soon include interactive calendars for community and civic events."
Town mayor Ian Haffenden said he welcomed the move to modernise the website.
He said, "These days it is important we keep apace with the needs of our residents.
"The result of the redesign is a fresh and more user-friendly website that I'm sure will engage with both frequent and occasional users."
Hailsham Town Council says it would like feedback from residents on the new design. Any comments or suggestions should be e-mailed to terry.hall@hailsham-tc.gov.uk
