These are services, such as mortgage advice and conveyancing, that you need for your property transaction. Estate agents often use the term because they are ancillary (secondary) to their service.
Nearly every ancillary service provider gets most of their business by paying a referral fee to companies like Housecure. This doesn’t mean their referral fee influences our decision to recommend or display them on our site- the only thing that affects this is the quality of service they provide our users.
