Khalsa Aid rushed a team to flood-affected regions of Somerset and Burrowbridge to help distribute sand bags, warm clothing, antiseptic fluid, bottled water, food and other essentials.
"I think people are a bit amazed to see us with turbans and flowing beards, but at the end of the day what they see is a human being and we see our fellow countrymen suffering," said Khalsa Aid director Ravinder Singh.
The Slough-based charity, launched in southeast England in 1999, has coordinated relief efforts during disasters and emergencies in several parts of the world, including the Philippines, Haiti, Kosovo, Afghanistan, Syria and the Indian states of Gujarat, Orissa and Punjab.
Referring to calls for the British government to re-direct foreign aid to countries like India in order to tackle the ongoing floods, Singh said the issue makes one "wonder on moral grounds why dont they give half of that 250 million pounds to these people who need it".
More wet weather is affecting flood-stricken parts of the UK.
He added: "The people in the country who make that foreign aid possible are suffering."
More wet weather is affecting flood-stricken parts of the UK, with severe flood warnings in place along the Thames river and Somerset.
Fourteen severe flood warnings remain in place in Berkshire and Surrey, and two in Somerset. The warnings were issued after more homes were flooded and properties along the Thames evacuated today.
Authorities said that thousands more were at risk. Flooding is also disrupting train services in parts of the country.
The Met Office has severe weather warnings in place for rain across parts of south Wales and southwest England, cautioning that "with ongoing flooding in some places, any further rain will only add to the problems".
The Environment Agency has issued 350 less serious flood warnings and alerts, mostly in southern England and the Midlands.
