Fusion Consulting Group Reviews 

Charmaine was excellent throughout the process! Highly reccomend!

I’ve been a client of Fusion Tax for a long time - 8 years - but the last year and a half I have experienced a downward spiral of service standards.

There has likely been a high volume of turnover because every other associate seemed to be leaving, have left or typing an email on their last day. Nevertheless, there was alot of chasing on the part of the client to meet tax return deadlines, missing filing deadlines, unresponsiveness, unclear and inadequate advice to specific questions. There seemed to be various instances of “I was on holiday” after bouts of silence. I even had another client’s return sent to me to review. I don’t know how this is even acceptable.

My written feedback met with lukewarm response and apologies “if the communication throughout the process was not what you were expecting”. Extremely disappointed and have appointed another firm without delay. The vast difference in standards is a huge breath of fresh air.

Charmaine has been very helpful throughout the interview process, with quick replies and providing feedback. I felt supported and even with a misunderstanding from the company she quickly called to rectify it.

Charmaine is very helpful and friendly person. She looks after her clients very well and prepares candidates well for interviews.

Charmaine is an amazing and professional recruiter who gave me great advice, explained the company's needs clearly, and helped me feel confident during my job search.

Charmaine Mundy, a senior consultant at Fusion Consulting Group managed to get my an interview as a Finance Assistant.
She was very warm and helpful in helping me to prepare for the interview. Really nice person, which helped me be calm and prepared.
Charmaine is a very good representative of Fusion Consulting Group. Very good asset for any company to have.

Note: A previous version of this review was removed because it contained personal information. I have rewritten this review to ensure it is in line with the Trustpilot policy

I worked with Fusion Consulting Group Ltd through an umbrella company in May 2025. What should have been a straightforward payment process became a lengthy and stressful dispute that was not resolved until November 2025.

During this period, I repeatedly chased payment for work that had already been completed. I received multiple updates and expected payment dates, but the issue remained unresolved for several months. This resulted in significant time, effort and unnecessary stress.

I maintained detailed records throughout the process, including emails, text messages and voicemails relating to the payment dispute. Due to concerns about how the matter was being handled, I submitted a report to the Employment Agency Standards Inspectorate and ultimately had to pursue a Small Claims Court action in order to recover the money owed to me.

I was particularly disappointed that, from my perspective, more attention appeared to be given to challenging reviews than resolving the underlying issue promptly. My Google review and a previous Trustpilot review were removed following concerns that they contained personal information.

Throughout the dispute, I felt that resolving the payment issue took far longer than it should have. The payment was eventually made in November 2025, but only after months of pursuing the matter through formal channels Small Claims Court.

I do not believe it should have required repeated chasing, the involvement of regulatory authorities and a Small Claims Court process to obtain payment for work already completed.

Based on my personal experience, anyone considering working with this company should keep thorough records of all communications and ensure they fully understand the payment arrangements in place.

Anyone who believes they may have experienced similar concerns should seek independent advice and contact the appropriate regulatory bodies where relevant.

Over the years, I have used various services provided by Fusion including preparation of accounts, tax filings/advice as well personal financial advice - particularly around pension consolidation/SIPP. I have found all parts of the group to be efficient, friendly, transparent and willing to go the extra mile. Based on my experience, I would have no hesitation in recommending them

They are very helpful and knowledgeable when dealing with personal finance.

I very happy being cared for by Fusion.
I have very little knowledge or understanding of the financial world so I put a lot of trust in them looking after me. They are helpful & prompt dealing with any queries I have which have been few.
I really can’t fault them - and I would say if there was a problem!!!

It was a great experience working with Mitch and the Fusion team. From the outset, they took the time to understand my needs and provided clear, strategic advice on how best to achieve my goals.

Very poor. More concerned with money and the bill with actual people very impersonal.

I engaged this firm under a formal consultancy agreement that clearly required prior notification and client approval before estimated hours were exceeded or additional work was undertaken.

Invoices were subsequently issued for additional work without prior written notification or approval, contrary to those contractual provisions. When formally challenged, I repeatedly requested documentary evidence demonstrating compliance with the approval requirements set out in the agreement. No written approvals or contemporaneous notifications were produced.

The matter continued for more than six months through the firm’s internal complaints process. While responses were issued, they restated the firm’s position without providing documentary substantiation of contractual compliance. The process ultimately concluded without evidence being produced to support the disputed charges.

There were also prolonged issues relating to VAT exemption support, with insufficient clarity regarding submissions, timing, and status despite repeated requests for updates.

This experience has been prolonged, stressful, and costly in time. My concern is not a simple disagreement over fees; it is the absence of transparent, evidenced billing aligned with the safeguards set out in the engagement terms.

Based on my experience, I would not engage this firm again and cannot recommend them to others.
Any current or prospective client should independently verify:
How additional work is authorised before being undertaken.

How invoices are calculated and supported.

Whether written approval is obtained before scope extensions.

Whether there is a clear documentary audit trail for all additional charges.

Professional services require transparency, accountability, and strict adherence to contractual safeguards. In my case, those standards were not demonstrated.

The reply is disingenuous and misleading. You have not provided any evidence and your rating proves your credibility and professionalism.

I spoke with a female staff member from your company today, and the interaction left me quite upset. The number of questions asked, the tone in which they were delivered, and the apparent lack of knowledge and training were all very concerning. The experience was surprising and disappointing, and I feel it is important to bring this to your attention.

My experience with Fusion Consulting has been nothing short of disappointing. Anyone who is looking to set up a group structure, please stay far away.

They have taken 2 years to set it up. You get passed around from different lawyers and no one takes accountability. After 2 years, I still don’t have a group structure.

Please, anyone looking to do work with fusion. Do not do so!

Fusion have been doing mine and my wife's tax returns for a number of years. Quite complicated returns but Fusion have always been efficient and most importantly accurate! They also have a dedicated client services team which is very useful for general enquiries about other services Fusion offer. Highly recommend.

My company uses multiple branches of Fusion for 360 business support and each department provides an excellent service to our business. A very strategic & personalised experience delivered by great people.

I completed an assignment with this company in May 2025 and was not paid for my work. Despite repeated chasing, wages remain outstanding.

The matter is now subject to formal proceedings, and a complaint has also been made to the Employment Agency Standards Inspectorate.

After leaving a review on Trustpilot, I was contacted by the company and told payment would only be made if the review was removed. Because of this, I was left with no choice but to report the matter to the authorities.

Future contractors should be cautious.

I have used Fusion for many years for my tax affairs. They offer an excellent, personal service, are extremely attentive and most importantly, do a very good in keeping my tax matters in good order. They are clearly a very dynamic organisation that is always looking to innovate to ensure they continue to offer excellent levels of service to their clients.

I engaged Mitch and Fusion a few years ago for specific tax advisory work for me and my family. I found Mitch and his team to be responsive, professional and technically highly skilled with their advice, and I continue to turn to him for any tax, finance and accounting advice that I need. I had no hesitation in recommending his services to other family members and friends with sometimes fairly complex corporate tax and accounting requirements, and they in turn have also been very satisfied with the quality of services provided.
