Online referrals will be rolling out to other TAS locations and treatments in the future.

Referrals for other TAS treatments and locations

For all other treatments and units follow the instructions below to make a referral.

The steps you need to follow to make a referral depend on whether or not your Trust has a Service Level Agreement (SLA).

I don't know if my Trust has an SLA

Telephone 0300 020 0496 (24/7, 365 days a year) to check if your Trust has an SLA.
