It is essential that you allow adequate travelling time to arrive punctually. Arriving late may mean that your assessment over-runs the following appointment and it is not fair to keep others waiting due to your fault. If you are likely to be late then you should telephone us to discuss whether your assessment can still proceed.


Payment methods

Payment is due at the medical assessment.
Payment may be made by cash, cheque, or
Bank transfer
