@MTS1980,
@Tipetoo is correct. In UK below 42 is non-diabetic, 42-47 is pre-diabetic, and 48 and above is diabetic.
So you have gone from pre-diabetic into the diabetic range. But don't panic! Your reading is not very high. Complications can be avoided if you can reduce your blood glucose.
Many of us have done that by adopting a Low Carbohydrate High Fat (lchf) approach to eating.
That means avoiding or reducing starchy carbohydrates like rice, breads, potatoes and pasta which turn to sugar quickly in our bodies so aren't good for Type 2 diabetics. We replace the energy wit healthy fats like butter/ghee, yoghurt, cream, milk, cheese, nuts, olive oil, avocados and oily fish.
Protein like meat and fish are good, and eggs.
Green leafy vegetables are good too.
