If an employee who has been diagnosed with diabetes requests to work from home, does the employer have to agree to the request?

Where an employee has been diagnosed with a condition such as diabetes, it is good practice for the employer to assume that the condition is covered by the disability provisions of the Equality Act 2010, rather than requiring evidence that the definition of disability is met. Before coming to a conclusion about whether or not it would be reasonable to make an adjustment such as allowing homeworking, the employer should consider the request carefully and weigh up all relevant factors, including: the impact on the business of making the adjustment; the cost and practicality of the adjustment; the efficacy of the adjustment in preventing the disadvantage; the amount of help and support the employee has already been given; and whether or not there are other adjustments that could be made that would assist the employee.
