Mazuma Accountants レビュー 

Absolutely rubbish service. A complete waste of money. Do not use these cowboys. No Management Accounts received & no means of contact; they never return calls.

great sales pitch even caught me off guard with extra cost at the end. Still i agreed to the call that was book a couple of days later ...no call ... i was supposed to be at a meeting with a account who was to busy to call me even though he was supposed to be in the meeting with me? i am still waiting on a promised refund 1 month later

I have been with Mazuma Accountants for several years now and love the ease in which they handle my accounts and tax returns. Recently I had fallen behind on my book keeping due to having a baby and all the chaos that comes with that, but they were still able to make sure that my tax return was submitted in time despite all this! Josie has been particularly helpful. Thank you so much!

Sian has been responsive and very helpful.

Terrible experience, they kept messing the self assessment for months, multiple times, I spent too much time to sort their mess, not recommended. Managed to sort it in last minute. Going to change accountants. Caused me too much stress, anxiety and financial loss as I had to spend my time to sort it.

phoned up and spoke with Lily at a moment's notice. She had all my info at her fingertips within seconds and facilitated my request immediately which put me at ease. Really impressed - thanks Lily Cope

-10/10 - I get a reminder to hand in all my documents by a certain date, I hand them in, then they need more time, apply for an extra 3 months, then force you to the last day of those extra 3 months, then your late get a £375 Fine from HMRC, Mazuma do this EVERY YEAR! and you can’t phone them unless you upgrade. They force you into the wall every year - they probably have very few staff and a bad set up - I only had 140 receipts for them for my entire tax year - what a shambolic set up this company has, I complained 3 times - I’m going higher again I will not be gaslighted with this utterly shoddy and incompetent organisation – they should be ashamed -10/10 I want a full years refund!

I have been using Mazuma for over 10 years and have always received excellent service
Everyone I have communicated with has been friendly and professional
A particular mention for Sian who helped me this year on a tight deadline and provided detailed additional information on a complicated topic.
Thanks to all

The Mazuma team have been the most incompetent and unhelpful professional services team I have ever come across.
They made errors in my initial accountancy set up and I have been paying for this 18months later. Every month they are out on my business accounts, requiring multiple tedious emails, waiting on telephone lines and apology emails where nothing actually gets sorted. I paid for VAT registration and services and Self Assessment both of which have not been completed in time, and I had to do them myself. I have complained on multiple occasions but still have not received an answer. I’ve had to report them to HMRC for fear of fines. This is truly a delinquent professional service. AVOID at all costs.

UPDATE: Unsurprisingly Mazuma seem to not be able to locate my information, which is pretty much par for the course whenever I call and complain. Is seems that the other 1 star ratings also have the same issue.

TO MAZUMA: If you look up your complaints system against my name, you should find 3 outstanding complaints there, as I have tried to get a resolution on multiple occasions without response before resorting to writing a review.

I feel a lot better having read the other reviews as I realise I wasn't going mad! I've been around in so many circles, raised concerns, had feedback from an "investigation" into those concerns which didn't take into account facts and hard evidence, and finally gave up. As a very small business (just me working part time) it really shouldn't have been this hard. I'll stop short of sharing the issues I experienced as I can see that the default response is the same as the investigation responses! All the customer’s fault!

28 Jan - thanks for your reply. It's correct in that I have now advised that I don't want to progress the issues any further, but it doesn't reflect that I said this in an email just 48 hours ago in an email where I said "I've run out of energy [...] trying to get answers to my queries", specifically in relation to VAT returns, SAT returns, errors and omissions in monthly reports from the date of subscribing (May 2025) to the date of cancelling (October 2026).

162 reviews out of 879 rate the service as 1 or 2 star. That's almost 1 in 5 people.

Currently less than a week away from the tax return deadline, and haven't received so much as a draft to look over yet.
When I did try and phone up to check on the tax return status 1.5 weeks ago, I was met with a sigh, and told that I have 'plenty of time'.
When I ask when I can expect my tax return, all I get told is that 'it will be with me by Friday', in other words one day before the actual deadline.
Considering HMRC warns you that payments can take a few days to process, this is cutting things much closer than I am comfortable with, and gives me no time to fix things if not done correctly.
Overall feeling pretty stressed and anxious by this entire situation. If I had known that my tax return was going to be left this late I likely would not have opted for this service.

Prompt service, recommendation of exactly what is going to be right for me without trying to oversell.

Hannah was prompt and efficient in addressing my requests. Very helpful support and happy with the service received.

I recently filed my self assessment using Mazuma and was helped through the process by Lucy Bryant. Lucy answered all of my questions promptly and clearly via email. What was usually a stressful experience became straight-forward - thank you. I wouldn't hesitate to recommend Mazuma for your accountancy needs.

Natasha is incredible. Great at personalising to your own needs. Cannot recommend enough.

Started well, they seemed like they knew how to support our business and the initial set up was ok, although we never recieved anything which detailed what our subscription consisted of.
I thought the system for emailing invoices and receipts would be a game changer but most wouldnt upload (no explanation given) and the ones that do upload go into the wrong month and there's no way to change months so every reciept needs to be uploaded seperately.
Such minimal contact.
Got an email telling me they were doing my VAT return when id already done it manually as I didnt know it was included. Waste of everyones time.
Canceled my subscription (with one months notice) beginning of December and have just had a second month payment taken. Laughable.

***Updating my review AGAIN because despite Mazuma's repeated responses that they have completed all work to their timescales, I still have outstanding bookkeeping from February 2026 and my tickets regarding this have gone unanswered. Posting here seems to be the only way to get a response.

---

I'm hoping that a Trustpilot review will get Mazuma's attention as I've been unable to get any support from them as a customer - or to get them to actually do the work I'm paying them for.

I joined Mazuma earlier this year when my accountant's firm was acquired by them. For a while nothing changed and I was happy enough. Then, in November, my accountant left Mazuma.

Since then there has been radio silence from them, despite repeated attempts from me to find out who was taking over and how things might change.

There was no handover, no communication, and over two months later not a single piece of bookkeeping has been done - in my busiest season of the year.

While Mazuma would claim to have responded to all my emails within their agreed timeframe, these responses all consist of "someone will pick this up today" and then they never do.

It's like shouting into the void and I now have almost 2000 unreconciled transactions and an enormous headache to deal with.

Wouldn't wish them on my worst enemy.

EDIT: Mazuma's response to this ticket (we need more information and we'll get back to you when we've looked into it) is how they have responded to every other enquiry. And then nothing ever happens. It just goes round and round and round

SECOND EDIT: Mazuma now appear to have edited their response to this ticket with many inaccuracies about how this was handled. They did bring the bookkeeping up to date, but this was most certainly not done to their agreed service level, which they advised me was a 5 working day turnaround. This took over two months to get resolved. Also, the point of contact assigned to me left the firm one week after completing this work. I have no idea who my contact person is now.

Sophie, your accountant administrator offered the personal touch with a phone call. Then, a follow up email to confirm information.

I engaged Mazuma Accountants in a hurry to correct the accounts of a small company with fewer than 30 transactions for the year. I had already prepared the accounts myself and was looking for a straightforward professional review and filing. I was charged almost £600 and was told the work could be completed within about a week.

Nearly two months later, the accounts I received were fundamentally wrong. Mazuma used the 2024 trial balance instead of 2025, which immediately demonstrated that the transactions had not been properly reviewed. There was no reconciliation of the trial balance, no sense-checking of figures, and no verification that the prior-year accounts they rolled forward even matched what had been filed with Companies House.

These are basic professional checks that should be standard for any competent accountant, particularly on a company with such a small volume of transactions. The errors were not minor or subjective judgment calls; they indicate that the work was not properly reviewed at all.

In my view, this constitutes professional negligence rather than a simple delay or administrative issue. I would strongly advise others to be extremely cautious before engaging this firm, especially if accuracy, attention to detail, and adherence to statutory filings matter to you.

Highly recommend Mazuma for your payroll needs. Our main point of contact Alison Edwards is friendly, professional and always incredibly helpful and highly efficient.
