Mazuma Accountants Reviews 

This is probably one of the worst companies we have ever dealt with, the customer services is shocking.
They do not answer the phones, or emails.
They have a neat trick with the phones, tell you they are busy and then cut you off, no option to ask for a ring back or leave a message.
We would advise anyone to give this company a miss.

I rarely leave negative reviews, but my experience with Mazuma has been extremely poor and is consistent with many other 1-star reviews I have since read.

Over a period of approximately 6 months, I had to repeatedly chase for basic information and corrections. My accounts and tax returns were submitted around 9 months late and initially contained incorrect figures. As a result, I received penalties including a Self Assessment fine (approx. £1,300) and a Companies House fine. Mazuma declined to assist with appeals, which I had to resolve myself.

After prolonged back-and-forth, Mazuma eventually acknowledged issues, corrected the returns, and refunded approximately £1,200.

Communication was a major concern throughout. Emails were often unanswered, calls were not returned, and I had to provide the same information multiple times. Notably, when I began formally challenging the situation, communication shifted from email to phone calls from different numbers, which I chose not to engage with in order to maintain a written record.

Despite paying for bookkeeping services, I was later advised (29/01/2026) that the bookkeeping for the 2024–2025 period had not been completed and was asked to provide this myself.

Following my departure, I am still attempting to obtain a clear breakdown of payments and confirmation of what services have been applied to the 2025–2026 period.

In my case, issues were only resolved after persistent escalation. Based on my experience, I would not recommend this service.

All of the above is supported by extensive email correspondence.

edit - the response below is contrary to my last review during the incident, when they denied all knowledge until i wore them down with 6 months of daily emails, furthermore, they have charged me for an additional year they didn't provide a service for, and they are pulling the same tricks as before.

Perfect start and brilliant service from Molly - thank you again. So friendly and helpful! Thank you for answering all of my questions.

Very happy with the service I was given from Molly. She took the time to take me through everything and made me feel even more confident in Mazuma.

The App seems really easy to use and I can actually create invoices and link my bank too. Thanks Molly for the demo

Excellent service from Molly Avery this week. Will 100% recommend to others

I appreciated all your advice Molly, professional, helpful, knowledgeable and personable… Thank you

Impossible to get hold of anyone. Send an email marked urgent. You dont get a reply. I've tried multiple times to sort out very important stuff regarding my accounts and when booked an appointment for a phone call I never received one. This company is a scam. They will take your money but not do the work. Avoid at all costs.

Emma was unbelievable with handling our case and is a huge reason as to why we’d continue

Emma was a huge help and great customer service. Definitely recommend Emma if you need any help or support!

Great service. Always professional. Little hiccup was sorted quickly. Special thank you to Emma Wastell

Simon Pitarresi in the Payroll department provides excellent service. No query is too much trouble for him to sort out.

Hannah Chave-Jones was very supportive by giving me advice, sending me links and signposting.

Hannah Chave-Jones was professional in her interaction with me and showed a willingness to listen and being attentive.

Every month I require certain detailed information about my business accounts. Sian delivers this without fail with total professionalism and dedication.

I had a great meeting with Leighton Watkins. In no time at all he had shown me how to use the the Mazuma desktop app. Everything was explained very clearly and the shared screen made it even easier to follow.
I now feel confident to get my books in order. Thanks Leighton!!

I used Mazuma fore my business for many years and they were always helpful. I had a nice catch-up with Hannah yesterday.

I have not had my books done for months and am passed from one person to another with zero answers as to what is going on, just each one saying I shall look into it. It's shocking and April 5th is less than a month away. I need to make decisions in my business. - UPDATE Your reply says everything will be done by end of week, it is now the following Monday and still nothing.

Leighton onboarded us to Mazuma's MazApp platform and the process couldn't have been simpler. He answered all our questions with expert knowledge, showed us around the platform with confidence and followed up on our queries really quickly. I'm really looking forward to using their super simple platform and not having to do bookkeeping and VAT returns anymore!

They don’t listen and there is no number to speak to anyone, you have to raise a support ticket on there website,

I don’t use them because they don’t listen, I own tree companies and they have tried to get me to switch from my current accountant which is something that isn’t going to happen as they are outstanding.

I get 3 contracts sent to me every day and I have consistently told them to remove my data and they don’t, keep sending me contracts with a price which is really cheap but it isn’t about cheap it’s about outstanding service,

I am now reporting them to the ICO and there governing body as they don’t listen to removing my date and sending me three contracts every day, it’s like they are bullying me to use them stay well away

E-mails still coming through this morning with contracts to sign
