What our Clients say...
-
"I have always been extremely happy with the service you provide both on a professional level and a personal level, so wanted to say a genuine thank you for reviewing all my contracts over the years and all the additional advice you have provided."
Jeremy Fletcher Black Diamond Consulting LtdRead more -
“I engaged Charlie to assess my contract prior to starting at a new client. Charlie was fantastic throughout the process. She demonstrated deep understanding of the relevant legislation and always responded promptly and professionally. As an independent expert her advice and opinion were well received by the end client, who provided an outside status determination. With Charlies input, the end client could demonstrate reasonable care had been taken – a win-win for both parties! I cannot recommend Charlie highly enough."

“I’ve used Bauer & Cottrell for several years and wholeheartedly recommend them to everyone that I work with. They’ve successfully negotiated a whole range of adverse and risky terms out of contracts on my behalf, far more effectively than I could’ve by dealing with the relevant agents myself, and taught me more about the practical side of successfully engaging with clients (outside) of IR35 than any other source of information. Their Contractor Guardian Plus service provides me with the complete peace of mind that I don’t believe is otherwise readily achievable within the means of an independent contractor.”
Adam Williamson Network Guy Consultancy LtdRead more -
“Thank you so much for your really prompt, efficient and calm approach in negotiating changes to the proposed contract with my client, to ensure it correctly reflected working practices. You made the whole process seem so straightforward and Bauer and Cottrell’s reputation provides well deserved reassurance that it’s been done properly.”
Stephen Penfold MTwenty International LtdRead more -
“The Bauer & Cottrell IR35 Review Package I receive through my accountant has been extremely good value and most importantly how/why the review is done; so it is done correctly, thoroughly and the determination is accurate, in line with current legislation. I have been continually recommending Bauer and Cottrell/this approach to my peers. Even now, where the client is responsible for making the determination, Bauer and Cottrell review all the paperwork and examine the actual working practices, to ensure this has been done correctly. Additionally, when checking the supporting paperwork, Bauer and Cottrell have ensured this accurately reflects the determination and actual working practices. With your help we have the right outcome done properly, which for a recent review, the client very much appreciates being able to retain me for a time sensitive/important project and we know that we are compliant. IR35 determination is complex and often misunderstood. Bauer & Cottrell’s expertise and experience ensure a correctly determined outcome.”

“As someone new to contracting and the complexities of the IR35 regulations, I engaged Bauer & Cottrell Ltd to advise me on an agency contract. Throughout the entire engagement their friendly and professional team were a joy to work with. Their specialist consultant (Charlie) was extremely knowledgeable, responding swiftly to all my questions, and quickly negotiated a compliant contract with the agency on my behalf. I’ve since engaged them again for a subsequent contract and experienced the same fantastic and timely service. I would not hesitate to recommend their services to others in a similar position.”
Ben Moss Kaizen Path Consulting LtdRead more -
“I had to consult with Bauer & Cottrell regarding the IR35 status of one of my contracts, and the service they provided was immaculate, with super fast responses, and full support, including assessment, contract templates, and many revisions until the contract was as watertight as it gets. To top it all, the service was pleasantly friendly. I would highly recommend them for anything IR35 related.”
Haitham Seelawi Eva-Ayla Seelawi ML LtdRead more -
You have all been a pleasure to deal with, and extremely helpful and I look forward to dealing with your company again in the future.” “I have nothing but good words to say about you and the team.
