A new study has unveiled the best companies in the UK to work for
The research, conducted by employee development platform Zensai, analysed company review data from Glassdoor.com for all companies with more than 100 reviews in the UK. Eight factors were collected to compile the index for each of the 206 companies studied. Each factor was weighted and used to create an index score out of 100 for each company, upon which the final ranking was based.
Octopus Energy comes out on top as the best company in the UK to work for, with an index score of 87.16 out of 100. The energy company, with CEO Greg Jackson at the helm, was founded in 2015, and the 722 reviews in the UK rate it highly across the board.
The company scored an average culture and values rating of 4.56 and an average diversity and inclusion rating of 4.55. The average senior management rating scored well, at 4.27, and the average career opportunities rating scored 4.22. Employees on Gassdoor.com demonstrated how happy they are to work for the company, with 86% saying they would recommend it to a friend.
In second place is Bain & Company, with an index score of 85.92 out of 100. The management consulting firm is clearly well-liked by its employees. 92% would recommend the company to a friend. However, the average work-life balance rating only scored 3.40, the lowest on this top ten listing.
Ranking third is Mastercard, with an index score of 82.00 out of 100. The companyโs best ratings were for diversity and inclusion, which scored an average of 4.40 and work-life balance, with an average rating of 4.31. The lowest rating for the company was for senior management, with an average rating of 3.96.

Commenting on the findings, Rasmus Holst, Chief Executive Officer of Zensai said:
โIt’s inspiring to see organisations like Octopus Energy and Bain & Company leading the way in fostering positive work environments. It is also interesting to see so many tech and software companies show up in this top ten listing of the best places to work in the UK.ย ย
โWhile salary is important, employees clearly also prioritise their well-being, as well as company culture and values when choosing where to work. Recognising and supporting what matters most to employees not only benefits the workforce but also contributes to the overall success of the company. We hope study helps inspires more organisations to prioritise their employees and continue making the UK a great place to work.โย
