My GP practice is every 12 months for type 2's, though had one in Dec and one in Jan and one in Feb the 2nd was because there was a referal to retest from the hospital. The Feb one was because I restarted monitoring and BS went very high for me, the next one won't be for 4 months.
After this I suppose it will go back to 12 monthly, but this time continual to monitor myself more often.
