Visiting service (domicillary) is actually the past. All dentists provided it pre 2006 new contract. After this it became the responsibility of contracting services . In my area no domicillary service was set up . Many others have some home visits but massive waiting lists (2 to 5 years). The treatment provided is somewhat limited and for those community services that provide home visits it tends to be a one off to deal with a problem, not an on going check up etc service.
Unfortunately the hoops you now have to jump through to,provide the service means that few private dentists provided it the service and those that do have to charge accordingly , and the treatment that can be provided is somewhat limited by the equipment needed.
