The very next sentence says:
People who are not often exposed to the sun should take a daily vitamin D supplement throughout the year.
I would say that "should" is stronger than "consider".
The NHS obviously credits people with enough intelligence to know whether they belong to a higher risk group. the majority of us (especially those with less than perfect bodies and/or concerned about skin cancer) don't expose enough skin outdoors for Vitamin D to be made.
People with the following conditions have problems with fat absorption, which affects the absorption of Vitamin D: liver disease, cystic fibrosis, celiac disease, Crohn's disease, and ulcerative colitis. PPIs can cause loss of bone density, so adequate Vit D and calcium is especially important. On the other hand, people taking certain drugs should check that extra Vitamin D is safe.
PS. I have my Vitamin D checked every year as part of a full blood test. It's not standard to include it, but I had a severe deficiency a few years ago.
