Getting an NHS admission to a private rehab clinics can also be possible.
UK residents are entitled to benefit from free addiction treatment programs through licensed community based NHS rehab or private residential recovery centres across the country with the right equipment. To qualify for NHS funding at a residential rehabilitation centre you'll possible have to provide evidence that you have tried to get in local community-based treatment options first. Getting into rehabilitation like this may be little longer, depending of whether your local addiction team is willing to pay for your treatment.
You can be referred to your nearest drug and alcohol action team by your GP.
Rehabilitation of NHS:
It may take months in organising admission into a private rehab clinic via the UK NHS or local addiction services and the result is far from certain. Funding through the EU cross border healthcare directive is however possible to gain a much faster access.
For UK based patients all information about that option can be found on the Alcohol Rehab Hampshire site.
