Last month, there were 114,780 residential property transactions in the UK, according to HM Revenue & Customs (HMRC).
This is higher than the seasonally adjusted figure of 104,590, which is often the quoted amount.
Using the non-seasonally adjusted data, the number for June is significantly higher than the 99,190 transactions in May. It also beats the high of 114,720 in August last year.
This is the first time this year that monthly figures have surpassed 100,000 for home sales.
HMRC reports that in 2014, there were over 1.2m transactions.
