What’s the difference?
Conveyancers are not solicitors, therefore they are not governed by the Law Society, they are governed by the CLC, the Council of Licensed Conveyancers.
Some lenders won’t allow you to use a licensed conveyancing company and they may even have restrictions on which solicitor you can use if they don’t belong to a particular approved panel.
A solicitor will be likely to cover or specialise in other areas of law aside from conveyancing whereas a licensed conveyancer would likely have passed exams to only do conveyancing work.
It’s difficult to state which is best aside from stating that the likely scenario within most law practices would be to employ a small team of licensed conveyancers being supervised and overseen by a specialist conveyancing solicitor.
