Since you cannot get more credit (other than a consolidation loan) while under debt review you may be looking for other ways to address your transport needs.
Family members may be able to loan you a vehicle or you may look at renting a vehicle during this time. Both of which can help you address your need but come with their own considerations.
Car rentals can be pricey since they factor in car services and maintenance etc.
Lending a vehicle from family can involve being beholden to them and making sure you are covered on insurance.
Another option is to look at public transport and service like Uber. If you do the math and really consider all the costs of petrol, car services, insurance and maintenance you may actually find that using such services is similarly priced to buying, but with lower risk.
Whatever you do, beware of scammers offering to get you out of debt review with false promises that you will be able to go and get finance for a car. They could trick you into losing all your progress in paying off your debt. Rather look for other solutions.
