The Living Wage in London is going up to £9.40 an hour, well above the rate being brought in by the Government next year.
The capital's Mayor, Boris Johnson, announced a 25p rise to the voluntary rate in London and urged employers to pay it.
The National Living Wage outside London is increasing by 40p an hour to £8.25.
Both figures are well above the national minimum wage of £6.70 an hour and the planned new National Living Wage of £7.20 for adults from next April.
