Islamic Relief Worldwide saw its income rise to almost £100m in the year to December 2014, with a surge in voluntary giving more than cancelling out a large drop in institutional donations.

The charity reported overall income of £99.1m in its annual report and accounts, filed last week, an increase of 8 per cent on the previous year.

Income is still down on the charity’s record year in 2012, when it topped £100m for the first time.

The accounts show a rise in voluntary income to almost £79m, a 37 per cent increase, but a fall in institutional income to just under £16m – a 48 per cent drop.

The charity said it continued to provide significant funding to offer aid in the war-torn country of Syria.

“The continuing plight of the Syrian people and conflict in Gaza contributed to the increased generous donations from the UK individual donors, DEC, and the global Islamic Relief family partners from across the world,” the charity said in its accounts.

“As the Syria crisis raged, we reached a staggering four million vulnerable people inside the war-torn country and nearby,” the charity’s chair and chief executive wrote in their joint introduction to the accounts.

“As well as assisting Syrian refugees in Iraq, our multi-million dollar programme also reached families fleeing violence within the country. As conflict escalated in Gaza, from the first day of the crisis we helped those affected.

“We also responded to fighting in the Central African Republic and South Sudan and devastating natural disasters in numerous countries.

“Crucially, we also protected communities from future disasters. In Bangladesh alone, in excess of 472,000 people are benefitting from disaster risk resilience projects delivered this year.”
