The North Springfield Walk in centre will close in March 2015 in favour of a new Urgent Care Unit to be located at Broomfield hospital.
The future of the walk-in centre, based near the Sainsbury's superstore, was settled at an MECCG public committee meeting on November 27 at the Chelmsford Civic Centre in Duke Street, Chelmsford.
The committee voted to close the facility which will save the MECCG in the region of £1m a year in favour of a new pilot urgent care unit operating out of Broomfield hospital.
The GP surgery based at the site will remain in operation.
The closure comes as health chiefs are looking to save £41.6 million by 2019 despite more than 30,000 patients visited the clinic in the past year.
The MECCG, which manages the annual budget for doctors, dentists, pharmacists and opticians in the communities of Braintree, Chelmsford and Maldon, hopes to balance its books at the end of 2017/18 by saving £6m next year, £11.6m in 2015/16 and £8m in 2016/17.
