Accenture topped the list and were presented with an award on the night. Chief Executive of Stonewall Ben Summerskill gave an encouraging speech outlining how far diversity in the workplace has come.
During the night Stonewall also celebrated several other awards.
Goldman Sachs were highlighted as having the best LGB Employee Network, Nationwide were named the most improved employer on the list and Chief Constable Alex Marshall was named the Individual Champion of the Year.
The Stonewall Workplace Equality Index is an annual assessment of employers that takes into account both policy and staff satisfaction through anonymous surveys.
The evening was also a great opportunity for LGB employees from across the UK to network with each other and start learning best practice from more successful organisations.
