Short answer: A government-backed loan letting you buy with 5% deposit. Income and price caps apply.
It is a special home loan for people who have a 5% deposit but not the usual 20%. The government underwrites the loan so banks will lend to you. You still borrow from a normal bank. You must earn under the income caps and the house must be under the price cap for your region.
