The lender will be making the deals for first-time buyers and next-time movers available through intermediaries initially.
It is offering five-year fixed-rates at 75% loan to value (LTV) with a free standard mortgage valuation.
Mortgage Solutions has asked if the lender will be serving remortgagors but has not received a reply.
The lender has already extended offer periods on new build properties to six months plus a potential further six months offers and last year increased its LTV to 90% on new build houses and flats.
Wider range of borrowers
Principality Building Society chief customer officer Julie-Ann Haines said: “We hope that these products will help to support a wide range of borrowers including first-time and next-time buyers to own their home.”
She added: “We’ve responded to broker feedback by introducing Help to Buy England products to our range of intermediary mortgages.
“We are focused on growing our business and continually review the products that we are offering to ensure we are relevant in the market place and providing the products that clients are looking for.”
Legal & General Mortgage Club new build manager Craig Hall added: “Help to Buy has now assisted almost 160,000 completions to date in England.
“It is great to see Principality extending its participation in the scheme and further support its commitment to the new build sector.”
