The Financial Conduct Authority has said that regulation around the mortgage market and the wider financial sector will remain unchanged following the EU Referendum.
Much of the UK's regulation is derived from EU legislation - including the Mortgage Credit Directive.
And the regulator warned that firms must maintain their commitments under those regulations moving forward.
It said: "Firms must continue to abide by their obligations under UK law, including those derived from EU law and continue with implementation plans for legislation that is still to come into effect.
"Consumers’ rights and protections, including any derived from EU legislation, are unaffected by the result of the referendum and will remain unchanged unless and until the Government changes the applicable legislation.
"The longer term impacts of the decision to leave the EU on the overall regulatory framework for the UK will depend, in part, on the relationship that the UK seeks with the EU in the future. We will work closely with the government as it confirms the arrangements for the UK’s future relationship with the EU."
The regulator added that it was in close contact with other parts of the establihment to monitor developments in the markets.
It said: "The FCA is in very close contact with the firms we supervise as well as the Treasury, the Bank of England and other UK authorities, and we are monitoring developments in the financial markets."
The earliest possible tme for the UK to exit the EU will be Summer 2018.
