The lender is making the changes to some of its first charge buy-to-let fixed rates, so brokers have until close of business today to secure its current deals.

Separately, another lender, Keystone, has told brokers it is withdrawing all its five-year fixes at the end of today in order to reprice.

But Keystone has yet to reveal the scale of the pricing changes.

In West One’s email to brokers, it says its Limited Edition range will see rates rise by up to 22 basis points.

Its standard and specialist core products will see the biggest hikes of up to 30 basis points.

Its complex, W2 and W3 ranges will see rates climb by up to 20bps As of tomorrow, two-year fixes will start at 3.09% and five-year fixed rates from 4.25%.

The broker email says all West One’s existing products will be withdrawn at the end of today.
