WWF UK's total income for the year ending June 2014 rose to £62.2m, an increase of £3.8m, or 7 per cent, from the previous year.

The largest increase in revenue streams came from legacies which grew by £3m between 2013 and 2014. WWF UK also experienced a rise in corporate sponsorship, bringing total revenue from that resource stream to £6.7m.

Despite the WWF’s rising revenue, the amounts of money being paid to full-time staff has fallen by over £900,000. Full-time staff numbers fell by four in 2014. The charity spent £155,000 on redundancy packages for the year, compared to £366,000 in the previous year.

The Living Planet Centre, WWF’s Woking-based headquarters, also saw its incoming resources nearly halve; dropping from £1.3m in 2013 down to £752,000 at the end of the financial year for 2014. Woking Council, the site's single largest funder, reduced its grant from £683,000 to £108,000.

A total of 19 people earned between £60,000 and £150,000, two more than 2013.

The highest earner, believed to be chief executive David Nussbaum, received £140,000 and £150,000, the same figure as he earned in 2013.
