Building society approvals rose 20% in the second quarter, according to new figures from trade body the Building Societies Association.
Its members approved 118,600 mortgages in the second quarter, up from 98,300 in the same period of 2015, and up 8% from the 109,800 mortgages approved in the first quarter.
The BSA said: “The figures show that societies maintained their strong mortgage market share, following the surge in transactions in the previous quarter to beat the change in Stamp Duty at the start of April.
“During the second quarter, activity may also have been affected by the EU referendum at the end of June.”
BSA chief economist Andrew Gall added: “It remains too early to tell how confidence in the housing market will be affected by the decision to leave the EU, but it remains business as usual for building societies.”
