Personal client manager

Although we are a small practice we take a great interest in all of our clients. Each client is allocated a client manager to assist with all your business queries, so we understand your business and its needs.

Software support

Why a chartered accountant, now

Software is quicker than ever. It still isn't accountable.

Apps and AI tools have made recording transactions easy — and we use them too. What they can't do is take responsibility for the result, or notice the thing you didn't think to ask about.

Someone signs it — and stands behind it

A chartered accountant's name goes on your accounts. As a firm we are members of, and regulated by, the Institute of Chartered Accountants. Software is not. If a figure is ever questioned, you have a person who answers for it.

HMRC holds you responsible, not your app

If a return is wrong, the penalty lands on you — not on the tool that produced it. We check the figures before they are filed, and if a question comes back from HMRC we deal with it on your behalf.

Judgement, not just calculation

Most tax questions have more than one defensible answer. Which one is right for you depends on your plans, your family, your timing and your appetite for risk — context that no tool has, because you have never typed it in.

We tell you what you didn't think to ask

AI answers the question you type. A client manager who knows your business raises the allowance you are missing, the structure that is costing you money, and the deadline that is closer than you think.

The rules keep moving

Making Tax Digital, shifting thresholds, new reporting duties. Keeping current with all of it is our job, not another item on your list — and not something last year's training data knows about.

A real person, at an office you can walk into

Every client gets a named client manager in Southampton, Portsmouth or Winchester. You speak to someone who already knows your accounts, rather than starting the explanation again each time.

We use the technology as well — we are a Xero Gold Partner and fully set up for Making Tax Digital. The difference is that you get a chartered accountant behind it.

“

Richard, Tawny, Ayesha and the team have looked after our company and personal accounts for around the last 20 years. Richard is very approachable and will always help, as does Tawny. Their pricing is reasonable and, although possibly not the cheapest, is well worth the cost for the services they provide. I wouldn't hesitate to recommend Mandair & Co.

Amri and the team have made my first 2 years of self-employment super easy and stress free! They are great at explaining things I'm not sure about, they are quick at responding to emails and always provide me with great advice on how to be more efficient with books etc. I would highly recommend to anyone, top quality service!

We have used Mandair & Co as our accountants for over 10 years. We did try another company who promised the earth for a short while, but soon found that we were paying twice the price for no extra value and returned to Richard and his team.

How much do chartered accountants charge per hour in the UK?

You will get a fair rate when you reach out to our thoroughly trained specialists.
How do I find a good chartered accountant?
When looking for a proven and reliable chartered accountant, there are several things that you must consider. For a start, you should check to see if the accountant is certified by any professional bodies, such as the ICAEW or ACCA. Next, it's important to take into account online reviews and referrals from friends, family or colleagues. At Mandair & Co, we employ several certified accountants, and we have also received many positive reviews over the years, making us one of the most reputable accounting firms around.
