“Nevertheless, brokers are our business, and we know they are soon going to be hit with a greater administrative burden, so we want to do all we can to make the transition as smooth as possible.

“In just a couple of months, the buy-to-let market will take yet another step towards greater specialisation, and I hope this tech-driven solution will quickly become the gold standard for brokers coming to terms with the new rules.”

Mark Blackwell, lending and surveying services director of eTech, added: “We are delighted to be working with OSB to deliver the industry standard buy-to-let hub.

“We have worked collaboratively to provide a solution that supports brokers and landlords and helps make OSB easy to deal with in a market becoming ever more specialist.”
