Diabetes UK said it is "delighted Public Health England is taking the NHS health check programme seriously".
The charity's chief executive Barbara Young said they were "disappointed in the past" that too few people had the opportunity to be risk-assessed by NHS health care professionals.
"We are particularly pleased to see it is committing to a target of 75% uptake of the programme per year", she added.
The National Diabetes Inpatient Audit, which examined data from 13,400 patients, found that a fifth of patients suffered from hypoglycaemia while in hospital.
Bridget Turner, director of policy and care improvement at Diabetes UK, said that "even a single" case of ketoacidosis developing in hospital is "unacceptable" as it suggests insulin "has been withheld from that person for some time".
There are thought to be 850,000 people who don not know they have type 2 diabetes.
A record breaking three million people have now been diagnosed with the disease, and experts are warning unless more is done to prevent the condition, the NHS could become burdened with unsustainable costs.
Diabetes sufferer Lynda Marks said dealing with the condition is much easier once you start talking about it.
She said: "It's difficult... to begin with."
Funds raised will help to pay for research into a vaccine for Type 1 diabetes as well as aiming to identify the 850,000 people in the UK who could be at risk from the condition.
Urgent action is required to stop the problem of diabetes, a health organisation has warned.
Barbara Young, Chief Executive of Diabetes UK, said:
Three million Britons have been diagnosed with diabetes, research has shown.
It is the equivalent to 4.6 per cent of the population, and experts say the figure is growing, warning it was a "grim staging post towards a public health emergency".
Research by Diabetes UK and Tesco has found that more than 130,000 people were diagnosed with the disease over the last year, with an estimated 850,000 people thought to have undiagnosed Type 2 diabetes.
Health experts say that the NHS could be burdened with unsustainable costs, unless more is done to prevent it.
All adults aged 40 and above should have a risk assessment for type 2 diabetes, according to the healthcare watchdog.
The National Institute for Health and Clinical Excellence (Nice) has also recommended that people aged 25 and above of South Asian, Chinese, African-Caribbean or Black African descent, who are at a higher risk, should also perform a test.
People can be assessed at their GP surgery or community pharmacy but they can also perform self assessments online.
Diabetes costs the NHS almost £12 billion a year and it's getting worse, new research has found. Read ITV's Science and Medical Editor, Lawrence McGinty's blog, here.
