Mr Woodhead said the average annual fee at Cognita schools was now £8,500 a year, when many London day schools charge well over £10,000. He promised that parents at the three newest schools - Cumnor House in Croydon joined the group in March - would not face massive fee hikes. "Fees increase slightly below the average for the independent sector," he added. Mr Woodhead, whose company is backed by private equity firm Englefield, said he believed the group could weather the financial storm. "We refinanced earlier this year before the current credit problems so we've got very substantial funds for acquisition and are keen to expand our portfolio in London and the South-East." He said Clifton Lodge would continue to enter pupils for GCSEs up to seven years early - where former owner David Blumlein, who will stay on as headmaster, thought appropriate.
