Omnia Outsourcing Avis 

I have only ever had Positive experiences with Omnia.

I cannot fault the service that I have received from Omnia Outsourcing. They are knowledgeable and efficient. I have also had the benefit of when I have missed something they have supported me to get staff paid, when the late submission was my own fault.

Since the first time Coral contacted me she has been most helpful and very professional. She has dealt with any question or query I had and always replied to me very quickly. She clearly has the resources, motivation and passion to help people. I couldn't recommend her highly enough.

My payroll service was transferred from Churchill Knight Umbrella to Omnia at very short notice, with no information provided about any potential impact. The only communication I received was a single email stating that this transfer would be “business as usual” for me and that there would be no impact which of coruse was a complete lie.

However, when they ran my first payroll, it was a complete disaster. They failed to contribute to my salary sacrifice pension, which resulted in me paying over £2,000 in additional taxes. They also did not reimburse my valid expense claim.

I have repeatedly called, left voicemails, and sent emails, but I have received no response whatsoever.

This has been a complete disaster, and I am extremely concerned about the way this company is operating. I intend to send a formal legal notice seeking compensation for my losses.

I would strongly advise others to proceed with caution if they wish to protect their time, money, and peace of mind.

Transferred from Churchill with 1 week notice.
Customer support is non-existent. They never answer the phone. Payments are consistently late. They are deducting salary sacrifice from payslips without your consent.
Completely unacceptable. Avoid them.

Umbrella contractor transferred over to Omnia from Umbrella Company UK with little warning.

Omnia have proved impossible to contact, no one answers the phone, emails are ignored.

My end client can't pay latest invoice as Omnia cannot verify the new bank details post transfer.

Still have not been paid and no response from Omnia to repeated attempts to resolve the problem.

Rubbish support, they have no courtesy to respond to emails, they do not even acknowledge emails or respond to them. Payments are delayed and they breach contracts because they dont honour contracts that Churchill Knight had with its clients before they offloaded.

I was transferred (without my consent and very little information) from Churchill Knight to Omnia. Another diabolical company. No responses to emails, no answers on the phone, no transparency over their services.

I am now looking into a company that actually has some customer service and some guarantees in place.

The whole thing is a joke.

No pay. No communication. No response to emails. Not answering phones. It's been a week. No reassurances or apologies received as this is clearly affecting many people. A decent company would have at least communicated a global email of sorts.
Total disrespect

Avoid using this company, transferred from Churchill Knight like many others didnt get paid for over a week, had no contact to explain or apologise, no accountability taken, a pathetic first impression and a last as won't be using again.

Similar to other recent reviews I was forced to transfer over from Churchill Knight. I have had no issues in the two years I was with Churchill Knight, queries were answered instantly and issues resolved very quickly. With Omnia I have had to chase my pay 3 weeks running. I have very little faith in the organisation, they never answer any calls or emails. On the one occasion I spoke to someone they advised me it was ‘teething problems’ due to me being paid weekly on a Tuesday and this issue would be resolved for the following week and yet here I am 3 weeks later wasting more time chasing them for my pay. I would avoid this organisation at all costs.

Omnia Outsourcing acquired Churchill Knight in early August 2025.
5 months later I am one of the many contractors transferred to Omnia who have not been paid for weeks.
Impossible to contact account managers or payroll staff.
The few emails I have received have asked me to coordinate invoicing with my supplier.
Utter incompetence, finding a better umbrella company won't be hard.

Similar experience to many others. Transferred from Churchill Knight. 1 week of pay has gone missing and no older pay documents transferred to their portal. Do not answer the phones, do not return calls, do not reply to emails.

I was on a confirmed monthly pay cycle with payment due on 6 February 2026. Following the transfer from Churchill Knight Umbrella to Omnia Outsourcing at the end of January, payment was not made on the agreed date and no proactive communication was issued.
I contacted support by email and phone on 8 February. I left a voicemail and was advised I would receive a response within an hour. It ultimately took three days and required escalation via my agency before the matter was resolved.
Payment was subsequently processed and a payslip issued, which I appreciate. However, for contractors, agreed pay dates are critical. Missing a confirmed payment date and failing to respond within promised timeframes understandably creates concern.
Large-scale transfers (2,000+ workers were referenced in communications) may create administrative pressure, but payroll reliability and communication are core services for an umbrella provider.
The issue was resolved, but improvements in responsiveness and proactive communication during transitions would significantly increase confidence.

No email reply, no telephone call answers and payment overdue for 3 weeks!

Terrible is an understatement. I have not been paid, my agency has been chasing them to get contract over since Churchill transfer. They don't take calls, they don't respond to mails, they don't pay.

Forced transfer to Omnia via TUPE but they are in breach of TUPE terms as they do not offer salary sacrifice for pension payments.
If taken to court they would be in serious trouble and would be liable to significant payments.
Very poor communication. Impossible to contact.
Avoid at all costs.

Another transfer from Churchill Knight. No instructions / guide provided for process - no response via phone.
Finally received a new activation email with no instruction, no guidance in terms of how to submit timesheets - still not been paid..

False promises of paying you, i haven’t been paid still I can’t get to work because they haven’t paid me and I’ve rang them over 20 times emailed of 6 times, useless company avoid at all cost! Even still now I am chasing my pay I don’t know how recruiting agency use this company gives them a bad name now I have to report them for scamming and stealing DONT USE THIS COMPANY ITS A SCAM !!

Failed to pay me and no communication regarding the delay despite emails and messages left on their unmanned phones. Will be reporting them to the appropriate authorities. Not recommended. One star.

Another transfer from Churchill Knight. Staff do not seem to know what they are doing and the communication is abysmal.

I emailed them 3 weeks ago to clarify what the reimbursement process was, followed up with another email and 2 calls. Once i finally got through to someone I was told to look at the portal. When showing there was no expenses option on the portal I was told to email them my expenses. When asked if this was the normal process they proceeded to say 'sure'. Excellent, really sounds like they know what they are doing.

They also did not pay me, voicemails & emails are not responded to. After calling 7 times I got through to a person who has had me on hold to payroll for 40 minutes as the only other option was for payroll to call me back which from experience will not happen. After waiting for 40 minutes I was told no one was avaliable due to a meeting.

I got a call back from Finn who, to his credit, has been the only person to follow through with actually calling me back. It was confirmed by Finn I will be on the next payroll however no explanation as to why my hours were not processed in a timely manner last week.

I eventually got paid before the end of the working day however overall this company has been inaccessible and it should not take a client constantly calling and chasing them to ensure they do their job.
Absolutely shocking 'service' I have started the process of moving umbrella companies and from the conversations I have had with various umbrella companies it seems they are all well aware of the mess this company are causing.

The fact I have had to pay for this 'service' is ridiculous when they can not even get the basics right.
