Hello, welcome!
I am currently embarking on this journey so I'm not the expert. However there are NICE guidelines:
https://www.nice.org.uk/guidance/ta151/resources/insulin-pump-therapy-for-diabetes-pdf-374892589
And if you don't fit the NICE guidelines, there are other guidelines such as dawn phenomena, pregnancy, anxiety of dangerous hypoglycemia/ pathological fear or complications from diabetes - I know there was a female who was blind because of high BG who was able to get a pump because she couldn't see and she was able to get the libre sensors as well, etc.
You must have done a carb counting course, such as DAFNE and ask your consultant about it.
EDIT: I found it:

ASSOCIATION OF BRITISH CLINICAL DIABETOLOGISTS RECOMMENDATIONS
If you don’t meet the NICE criteria but you do fall under recommendations from the Association of British Clinical Diabetologists (ABCD), your clinic will need to make a strong case for you to be granted funding.
ABCD recommends that insulin pump therapy is also considered in the following situations:
• Pregnancy
• Acute painful neuropathy or symptomatic autonomic neuropathy if conventional treatment fails to enable adequate blood glucose control
• Hypoglycaemia unawareness
• Extreme insulin sensitivity
• Needle phobia
• Severe insulin resistance with poor blood glucose control (especially if the person has type 2 diabetes)
• Specific quality of life issues:
- Pathological fear of hypoglycaemia
- Marked glycaemic excursions/dawn phenomenon
- Excessive number of injections for optimised control
- Impaired exercise capacity, abnormal eating behaviour or an unacceptable number of sick days
- Shift work or frequent travel across time zones
- In children: sub-optimal school performance, exclusion from aspects of a full school life; behavioural problems (for example, mealtimes); adverse impact on family dynamics
