Berkett agreed to take a comparative 18% year-on-year cut to his 2009 pay packet, down from $6.9m (£4.5m) in 2008, but up from $3.1m (£2.03m) in 2007, reports The Guardian.
His total pay last year constituted a base salary of £564,347 - down 10% on his 2008 pay of £627,577 - along with stock and incentive plan awards of £3m and £159,518 in "other compensation". His actual take-home pay after deductions stood at £2.5m.
On April 25, Virgin Media's compensation committee - chaired by former ITV boss Charles Allen - awarded Berkett a £100,000 increase in his basic salary to £650,000, backdated to April 1, 2010.
The salary bump was to "reflect the increase in responsibilities Berkett has taken over, as per the planned transition with the executive chairman, as well as his performance".
Last year, Berkett assumed a number of duties from executive chairman Jon Mooney towards taking on all responsibilities as of January 1, 2011, when Virgin Media's chairman role becomes non-executive.
Mooney received a total pay package of £5.1m last year, including a base salary of £737,861, while Allen took home total pay of £264,582.
In comparison to Berkett's remuneration, Sky chief executive Jeremy Darroch received a pay packet of £2.3 million for the 12 months to the end of June, including a base salary of £825,000. He also received 600,000 shares worth over £3m.
