Keystone has increased broker procuration fees from 0.5% to 0.6%.
The buy-to-let lender has also reduced its 5-year fixed rate mortgages by up to 0.40%, with rates starting from 4.39% to 75% loan-to-value.
David Whittaker (pictured), managing director of Keystone, said: “Despite the Brexit result, its business as usual at Keystone and as you can see we have been very busy.
“The reduction in rates means that we are now able to better compete on pricing, particularly with 5-year fixes.
“Brokers will be particularly pleased that we have been able to up the procuration fee to 0.6% of the loan.”
Keystone has launched a new online broker portal, known as KASS (Keystone Application Submission System), which it said will speed up case processing and allow brokers to track the stages of every deal.
