The lender will offer a pair of deals including a two-year fixed rate product at 4.99% and a five-year fix at 5.49%. Both will be available up to 95% LTV and come with no product fee.
These two products are the same as those available through direct channels.
NatWest had previously caused controversy by limiting its Help to Buy mortgages to branches and telephone staff at launch but now joins Aldermore, Halifax, Santander and Virgin Money in offering Help to Buy products to mortgage advisers.
The lender is also reducing its two-year fix up to 60% LTV to 1.85%. It was previously on offer at 1.89 % and comes with a £995 product fee.
Mark Bullard, head of sales at NatWest Intermediary Solutions, said: “There has been a lot of anticipation about the introduction of mortgages to support the Help to Buy mortgage guarantee scheme, so I am delighted that we now have these deals available to intermediaries.
“It’s a great way to kick off 2014 which promises to continue the market improvements seen in 2013.”
Elsewhere, Mortgage Trust has launched a two-year buy-to-let tracker at 2.89%. The product is available for purchase and remortgage with free valuation and a 2.50% fee.
There is also a 2.99% two-year tracker with a 2.50% fee for remortgage only. Both products are available up to 75% LTV with a £150 administration fee.
John Heron, director of mortgages, said: “The two new trackers are very competitive; especially the 2.89% and we expect this to be very popular with intermediaries looking for a great value product for small-scale landlord customers.”
