Dave Thomas
Owner - Professional Construction Recruitment
"As we move into another period of uncertainty I would like to thank you and your team for your support and service for many years but particularly since March 2020 when everything changed. I have known Jay for over a decade and when he set up Omnia with Iain and Dale, we knew it would be a success. ECS have partnered with Omnia, from day one, to engage our umbrella contractors and, more recently, also use their bureau service to payroll our internal staff. Omnia’s services are modern, hassle free and each one of our employees receives an app to retain payslip information, manage holidays and can benefit from a rewards scheme. We have a great relationship with Omnia, both personally and professionally, and would have no hesitation in recommending them. I look forward to continuing to work with you."
Chris Evans
