Find your local Sensory Loss Team, usually part of the County Council in the UK. Depending where you come from, the team names differ. They may have lumped together Deaf Services and the hard-of-hearing because of budget cuts. It is not ideal but it is the appointment that you want. You have to be a bit persistent as the person who answers the phone may never have heard of Quietum Plus. Once you get an appointment and the wait is from 6 days to 6 months, depending on clinical need, they will assess you. Some charities that specialise in deaf and hard-of-hearing issues have funding to do assessments and will often give you more time. They can be found easily from an internet search. Make a list of everything you want to ask. It is surprising how much you can forget when under pressure.
