His comments, made during a speech to the Muslim News Awards for Excellence in London on Tuesday, mirror promises he made in Israel last month in regard to kosher meat.
He told the audience on Tuesday: "Really tackling Islamophobia means making absolutely sure that no Muslim is held back from living their life or reaching their goals, simply because of the faith they follow.
"Soon the food will arrive and you will all be able to eat. Let me make it absolutely clear, that while I am Prime Minister of this country, halal is safe in Britain."
Last month, Denmark banned the slaughter of animals for food that are not stunned, therefore implicating kosher and halal meat.
