Accounting Review from Dmitrii Legetskii
This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

I don’t usually write reviews but every now and then i come across an extremely good service that deserves a mention. Professional, proactive and knowledgeable. Mohit and team went the extra mile and provided more than just the run of the mill services that a lot of accountants provide. I did my due diligence on 2 other accountants at the time and i’m pleased to say that Cloud not only impressed during the initial stages but also on delivery. The other accountants were just an “admin” service. Without sounding arrogant i have enough skills with a calculator and experience of completing online forms to do without them. Mohit and team provide a proper “value added” service with advice to boot.

Marius-Cristian Frunza's Review Sourced from Google
We would like to extend our sincere appreciation to Clear House Accountants for the outstanding support provided to our company throughout the past year. As a growing startup in the UK, it was essential for us to have a reliable accounting partner capable of guiding us through every stage of our financial operations, and CHACC has exceeded our expectations.
From day-to-day bookkeeping to the preparation and submission of statutory financial statements, your team has consistently demonstrated professionalism, accuracy, and attention to detail. The guidance provided on corporate tax matters ensured our compliance with HMRC requirements while optimising our overall position.
We are especially grateful for the expertise you brought to navigating R&D tax credit claims, which can often be complex for early-stage companies like ours. The clear explanations, thorough documentation, and efficient handling of submissions allowed us to focus on innovation while knowing this critical process was in safe hands.
What we value most is the end-to-end approach you offer. Rather than treating each service in isolation, you provided us with an integrated solution that supported our business at every step. This has given us confidence in the accuracy of our financial information and allowed us to make better-informed decisions as we scale.

Holly has been a great help recently both in terms of my business and personal affairs. I am in the process of making some business structure changes in my private dental practice and she has assisted me with all the lengthy paperwork, ensuring that everything is in order. In addition, she has assisted me in researching properties and locations. I would not hesitate in recommending her services as her support has been invaluable to me at this extremely busy time and has allowed me to focus on my patients.

Terri has been an incredible SmartPA assistant for our family over the past 18 months. Her support has been invaluable in managing our busy work and home administrative tasks. Throughout our travels across Europe, the US, and Canada, as well as during our recent move to a new house and country, Terri has been there for us every step of the way. In particular, I have appreciated that Terri has used great judgment in assessing options on all fronts and hasn't just gone for the easy road of blindly following orders. I have trusted her as a "second me" and that has been so helpful. We couldn't have done any of this without her!
