Loans are available between £25,000 and £570,000 and new-build properties are excluded.
A Barclays spokesperson said: “We are looking forward to supporting customers in their next steps as homeowners with the launch of two new 95 per cent LTV products.
“These products are available under the government’s mortgage guarantee scheme and are open for applications from Monday.”
The lender is also extending the maximum loan size on applications higher than 85 per cent LTV.
For houses with a loan to value of more than 85 per cent, the maximum loan has increased to £570,000, and for flats it has risen to £275,000.
This is available on all purchase applications including first-time buyers.
