Santander and Barclays have committed to continue lending to clients advised by Financial Ltd.
A spokesman for Barclays says the bank will not follow suit.
He says: “We have reviewed the matter and we will continue to lend to clients advised by appointed representatives of Financial Ltd.”
Santander also says it will continue to support new business through Financial Ltd and has no plans to place restrictions on the firm.
Halifax says it has a ongoing broker monitoring in place and has no plans to restrict lending via Financial Ltd brokers.
Financial Ltd managing director Brian Galvin says the network has not been notified of any other suspensions.
He says: “We have been in contact with lenders and the majority are happy with the changes we have made. We are hoping to get the situation with NatWest resolved next week.”
