Whilst the NHS is free at the point of delivery, the care expenses are not offered for all treatments and circumstances. There are several factors that go into deciding whether the treatment you are looking to receive will be available to you and your individual circumstances.
For example, some procedures and treatments are only available to specific groups, or only for those who it is considered a medical necessity and who have been referred by their GP. It is important, therefore, to consult with your GP beforehand to see if your particular treatment is covered by the NHS.
