The challenger bank entered the market in 2010 but had only lent on properties in England and Wales until today, Monday 10 June.
Aldermore had been planning the launch into Scotland for some time and will offer a full product range. Last month the lender announced former Ulster Bank intermediary head Steve Carruthers would head up its distribution team in the country.
Charles Haresnape, managing director of residential mortgages for Aldermore, said ahead of the launch: “We’re delighted to be extending our service into Scotland at a time when the housing market north of the border is starting to show signs of renewed confidence.
“Our range of both residential and buy-to-let mortgages will give brokers additional product choice and our personal service, which is based on skilled underwriting rather than automated credit scoring, will undoubtedly be a welcome development.”
