The deal includes two identity checks and two telegraphic transfer fees as standard, and is available through its EConveyancer platform.
ULS said the service will start at £350 but could not yet disclose which networks it is available through.
ULS Technology CEO Steve Goodall (pictured) said the firm had been hearing how important it was to offer an inclusive, fixed fee remortgage proposition.
“Over the last 12 months we have been working tirelessly to develop products that add extra value for our brokers,” he said.
“Today, we’re happy to reveal our next product which we believe sets a new benchmark for transparent quoting.”
PLS Solicitors managing director Daniel Hickey said: “Our clients expect transparency from the start of the process, so ULS technology’s new Fixed Fee Remortgage is something we strongly support.”
