Try travelling south to Carlisle. My mothers GP is a panel doctor, and we have our medicals on 31st Jan. Estimated 2 hrs for 2 adults & 2 kids. Prices as follows;

?90 - Adult Medical
?70 - Kids medical
?110 - Adult Bloods
?40 - Adult x-ray.

He has been my mothers GP for 30 years...she's still alive as well, so he must be fairly clean though!

Feel sorry for you though Jento
