Santander has announced a series of rate increases for new business and product transfers, occurring on both residential and buy-to-let (BTL) products.

The most significant changes take place within the BTL two-year fixed range, where the rate for the 60% LTV product with zero charge has been increased by 10 basis points to 1.79%.

The 75% LTV product with zero charge has also gone up by 10 basis points, to 1.94%.

Other rates in this category have been pushed up by 5 basis points.

Within the BTL five-year fixes, selected rates have increased by 5 basis points, leaving the 60% LTV product with zero charge at 1.94% and the 75% LTV with zero charge at 2.09%.

And the lender has raised some rates in its residential range of two-year fixes by 5 basis points as well.

For product transfers, Santander says that increases of up to 10 basis points take place at up to 85% LTV for fixed residential products and, for BTL and consent to let products, increases of either 5 basis points or 10 basis points take place.

Santander previously raised its tracker and standard variable rates by 25 basis points last Friday.
