During the first six months of the year, the value of the loans completed by the specialist lender was 17% higher than the same period in 2014, and 79% higher than H1 2013.
Dragonfly also saw a 10.5% uplift in the volume of loans in the first half of 2014 and 78% on H1 2013.
Numbers increased across both its residential and commercial divisions.
Mark Posniak, head of sales and marketing at Dragonfly Property Finance, said: “Last year we said that we were targeting £2bn of completions by the end of 2015, and having just delivered our strongest first half yet, we have a good chance of getting there.
“The impact of our commercial division is becoming stronger by the day and this is providing added momentum.”
