Ben Summerskill, Stonewall’s chief excecutive, said that the results were significant because it was only 10 years since gay people won legal protection in the workplace.
“Britain’s 1.7 million gay staff and 150,000 gay university students can now confidently use the Index to select a welcoming employer, or look further, safe in the knowledge that they are protected from discrimination,” he added.
The Index is based on a range of factors, which include a confidential survey of nearly 9,000 lesbian, gay and bi-sexual employees.
Noteworthy performances were also demonstrated by MI5, which came in at number 26 this year, having made its debut onto the list at 62 last year. The London Ambulance NHS Trust likewise leapt more than 70 positions to take the 22nd slot.
