That’s a really good question

Being Type 2 diabetic and treated with metformin tablets does not automatically stop you becoming a bus driver. In fact, many drivers successfully work in the industry while managing Type 2 diabetes.

For PCV (bus) licensing in the UK, what matters is that your condition is:

Well controlled
Not causing episodes of severe hypoglycaemia (low blood sugar)
Properly declared during your medical

As part of the licensing process, you’ll complete a medical form.  They may request additional information from your GP, but being treated with metformin alone is generally not a disqualifier.

The key factors are:

Stable blood sugar control
No recent severe hypos
Ongoing medical monitoring

If you’re considering applying for a trainee role, I’d recommend being open about your condition during the medical stage, it’s about safety and making sure you’re supported properly, not ruling people out unnecessarily.
