The government has saved £41m in website costs since July 2011, with the total number of sites down by 61 to 383, according to official figures.
The news comes as the government moves to accelerate the closure of its website estate and prepares to switch off its main information site Directgov and Business Link sites, which will be replaced by Gov.uk from October 17.
The total cost of running government sites was just under £108m for 2011/2012, according to the annual Reporting on progress: Central Government Websites findings from the Cabinet Office.
The Department for Health had the most expensive website running costs of the 20 central government departments listed, spending £21m on websites and a further £1.4m on staff-related costs.
So far, 1,700 government sites have been axed as part of Martha Lane Fox’s review of public sector digital services in October 2010, which recommended government should have a single domain for its digital interactions.
“Gov.uk will support the closure of many more central government websites by making information available in one place,” said the document.
The next phase will be transition of 24 departments and a handful of agencies across to Gov.uk by the end of 2013, according to a Cabinet Office spokesman.
“Phase three is the transition of remaining departments and agencies, and will take place between March 2013 and March 2014. This will bring everything published by central government under the single domain, with the exception of a few specifically exempted websites,” he added.
