NatWest and parent brand Royal Bank of Scotland had previously restricted Help to Buy products to direct channels when its first Help to Buy mortgages were launched last October.
The lender said in December it would launch Help to Buy mortgages through brokers in January and has now confirmed the launch will take place next Tuesday.
The products offered through brokers will be the same as those available through direct channels.
Graham Felstead, head of NatWest Intermediary Solutions, said: “It’s great to start the New Year with some positive news like this.
“We have supported intermediaries with mortgages for the government’s first Help to Buy scheme, NewBuy scheme and previous shared equity schemes, so I am delighted that we are now able to provide brokers with the opportunity to help more clients who don’t have a large deposit.”
Lloyds Bank is the latest lender to enter the Help to Buy mortgage guarantee scheme and will be followed by Santander when it unveils its product range this Thursday.
