Its Help to Buy and Shared Equity offering is now available in Scotland and Wales and the bank has also launched its support of the Help to Buy London scheme.
New products include a homemover two-year fixed rate starting from 2.19% up to 75% LTV and a five-year fix from 2.94%.
Remortgage two-year fixes now start from 1.99% up to 60% LTV.
TSB is also reducing rates across its two, three and five year Homemover fixed rate mortgages and its two year Homemover tracker.
Beverley Bradford, Head of Intermediary Performance, said:
“It is great that TSB is now able to expand its Affordable Housing range to Scotland and Wales after the success of the schemes in England. TSB was born to help local communities thrive, this now offers an alternative option for home seekers across Britain who are finding it difficult to achieve their dream of owning their own home.”
