Halifax has adjusted products in its remortgage range with some rates increasing by up to 0.14 per cent and others cut by up to 0.17 per cent.
The remortgage deals affected include affordable housing shared equity products and shared ownership scheme.
The lender did not give any examples of specific product changes.
Meanwhile, BM Solutions has also overhauled its buy-to-let mortgage rates.
Remortgage and let-to-buy products saw a range of reductions across two-year fixes at 60 per cent and 75 per cent loan to value (LTV) and five-year fixes at 75 per cent LTV.
The cuts were applied to products with £0, £995 and £1,995 fees.
Product transfer deals at 60 per cent LTV with £995 fee also had rate reductions, while the 75 per cent LTV versions were increased.
And the lender aligned its further advance rates with its two-year 75 per cent £0 fee product transfer deals.
