Clients Testimonials

"For anyone considering outsourcing their payroll, I would highly recommend Omnia. We recently approached them to take over our staff payments, and the communication throughout the consultation period was brilliant. The first payments went through seamlessly last week and the staff particularly like the functionality of the online portal. A special thank you to Rachel for the quick turnaround and Jay. We look forward to many years of working side by side.
My only regret is we did not bring you on board sooner!"
Ali Hassan
Managing Director H&W Catering Ltd
"Omnia are a welcomed addition to our preferred supply list of umbrella intermediary companies. They are a professional, compliant, friendly business, and always on hand to assist our consultants and payroll teams."
Donnacha Holly
CFO - The MCG Group
"We enjoy a very strong relationship with Omnia, and feel they are the perfect compliance and payroll partner for our business. Their excellent service levels frees up our time to concentrate on our own business."
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
CEO - ECS Resource Group
