Which? is yet to decide whether to keep its mortgage advice service when the pilot is finished in the next few months.
The consumer champion launched a fee-free service for its members in November last year.
Its advisers are salaried and receive no commission and the proc fees are used for Which? campaigning purposes.
Chris Gardner, commercial director at Which?, says the scheme has exceeded expectations and he has been encouraged by the response.
But he adds: “We’re not at the point of making a decision on rolling out the scheme. There are enough people to run a pilot but whether it is sustainable is an unknown.”
Gardner says he is unfazed by the regulatory environment. “We don’t see huge changes in mortgages.”
