It's worth bearing in mind that the London ICSs have been involved in the creation of this guidance, so you should be able to take this to your GP and say, "This is London guidance. Please give me "X" from the FP10 list.".
Warning. The last page does discuss prioritisation of individuals where required and provides guidance as to how this might be done. Be aware that this included, as some areas may decide to implement it.

As I understand it, most areas will have something similar to guide provision of CGM according to NG17, as well as a similar approach for children and adolescents set up specifically for them.
If your area hasn't done anything yet, I suggest waving this under their noses.
A brief update on the #Simplera now that I'm three days into using it.
Whilst I haven't been closely tracking proximity to fingerpricks, I've done the occasional "soft calibration".
The Dexcom ONE that went on at the same time appears to be tracking more closely.
#ATTD2024
The Simplera is regularly between 0.5mmol and 1.5mmol lower than the Dexcom ONE. At the current readings, it's a bit over 18% lower.
This sensor has been consistently low, but this is n=1.
The sensor is susceptible to compression lows, just like the ONE.

Let's talk about the app. The black background with white CGM trace & numerals are likely to be easier to see if you have vision problems, but the constant vertical axis set to the full range of the sensor, with no ability to reduce it, will annoy some.
Firstly, it seems that CKMs are prone to the same compression problems as CGMs, which should be no real surprise. You can see this here overnight where readings are lost. /2
From a measurement perspective, values are noticeably different with ketones present. The blood tends to be considerably higher than the sensor reads. /3
After two weeks, the #BattleRoyale (an n=1 comparison) for CGM is done. And there's clear water between the three sensors being tested, which were the Dexcom G6 & G7, plus the #Libre3. What follows is a brief summary of the results. /1
First up, the consensus error grids for all three sensors. Firstly, the Dexcom G6:

Caveat 1: earlier grid had an error, giving readings incorrect dispersion.
Caveat 2: Libre2 data from an earlier experiment due to device failing early in this test and replacement taking 10 days.
Thread.

Calibration was done according to manufacturer directions:
Dexcom ONE & G6 - never;
Aidex - when I felt it was needed;
Glucomen Day - every 24 hours;
Medtrum Nano - Factory calibration was enabled, but calibration was done when it appeared to drift too much;
Libre2 - never.

Dexcom ONE and Dexcom G6 have almost identical dispersion, as you might expect given the sensor and calibration technology is identical:
