Treatment after moving house

I may be moving to another part of the country-from Wiltshire to Cheshire. I am currently on Tecfidera- have been for nearly 4 years off and on. I collect this from my local hospital every 4 months after my neuro signs the prescription. If we do move I intend to make sure I have a supply to take with me to tide me over until I register with new GP.

Just wanted to know if anyone has moved area whilst on Tec or any other DMD and how easy was it to obtain new suppies of it.
