Basildon Council's Urgent Decision and Staffing Sub-Committee approved the award of contract to Enviro Building Solutions Ltd on Wednesday 23 January.
Conditional planning permission was granted at Basildon Council's Planning Committee in November last year. The project includes relocating the centre from Market Road to Nevendon Recreation Ground in Nevendon Road.
It also includes the demolition of the One Step Ahead pre-school which will be relocated into the new community centre.
Councillor Tony Hedley, Basildon Council's Chairman of the Regeneration Committee, said: "This is another significant step forward for an exciting project that will bring great community benefit.
"The existing centre is no longer fit for purpose and we are committed to working in partnership with the community association to ensure we give them a facility that will enable a greater range of activities.
"I would like to take this opportunity to thank the Veolia Pitsea Marshes Maintenance Trust following our successful bid for additional funding which allows us to make provision within the new centre for the pre-school, improving the facilities for its users.
"This will also unlock much needed redevelopment on the site of the old centre and form part of the wider regeneration of Wickford."
Doug Benjafield, Chairman of the Veolia Pitsea Marshes Trust, added:
"Trustees were fully supportive of the proposal submitted by Basildon Borough Council in 2018 as it clearly demonstrated that the new facility would be a valuable and well used community asset not only for the residents of Wickford, but also for members of the wider community.
"It's a very good example of how Landfill Communities Fund monies can be used to maximise social, economic and recreational benefits to local communities."
