Paul Adams (pictured), sales director at Pepper Money, said: “Service has clearly been a key issue across the mortgage market of late and our research shows that it’s impacting adviser recommendations.

“The most important element of service for landlord customers is consistent underwriting, followed by speed to offer and speed of decision.

“This shows that advisers and customers want certainty in this uncertain environment and so it is important to work with a lender that invests in underwriting expertise, commits to quick turnaround times and is transparent in publishing its service levels online.

“At Pepper Money we do all of these things, We understand what advisers need for their landlord customers and we work hard to deliver just that.”
