The voluntary living wage is to rise to £10.55 in London and £9 across the rest of the UK.
The rate will rise by 35p an hour to £10.55 in London and by 25p to £9 outside the capital.
The Living Wage Foundation said the increases have been largely driven by higher transport costs, private rents and council tax.
The new rates are £2.72 higher than the statutory living wage for London workers and £1.17 higher in other parts of the UK.
The statutory rate will increase to £8.21 an hour next April for workers aged 25 and over and will impact 180,000 workers.
More than 4,700 employers have signed up to pay the voluntary living wage to their staff, ranging from football clubs and banks to universities and retail firms.
Living Wage Foundation director, Tess Lanning, said: "Responsible businesses know that the Government minimum is not enough to live on, and today's new living wage rates will provide a boost for thousands of workers throughout the UK.
"Employers that pay the real living wage enable their workers to live a life of dignity, supporting them to pay off debts and meet the pressures of rising bills.
"We want to see local councils, universities, football clubs, bus companies and the other major public and private sector employers in every city commit to become real living wage employers.
"When they do, thousands of people get a pay rise, but other local employers also follow their lead."
Heathrow's chief financial officer Javier Echave, said: "Our colleagues are our most valued asset and deserve nothing less than the living wage.
"Today we celebrate the anniversary of our living wage accreditation and call on more businesses to recognise that successful companies are built on getting these foundations right and investing in their colleagues."
