About us

MAH, Chartered Accountants leverage their city firm expertise and experience to provide high quality advice but with an emphasis on personal service.

Our approach

We love the boring accounting and tax stuff (so much that we spend our free time researching and writing white papers!) and aren’t hindered by budgets or charge out rates. The benefit to you is that we make 100% sure that the accounts and tax are as good as they can be.

We are lean and hungry and we’ll do whatever it takes to do a good job. Why? Because we know that when we’ve made our clients happy, they’ve recommended us and effectively did our selling for us. 

Although we are a city firm of London accountants and have a fantastic location opposite Liverpool Street station, we are very efficient and have relatively low overheads and a flat management structure and this allows us to pass the savings to our clients.

Our expertise

We specialise in tech, financial services and contractors and have experience of working with startups, AIM listed plcs and large multinational businesses.

With this experience we can apply the most effective tax-saving techniques and put your business in its strongest financial position.

By dealing with the accounts of many prestigious clients, MAH has developed exceptionally accurate accounting services with rigorous attention to detail at all times – whether we are preparing statutory accounts, planning tax strategies or calculating forecasts.

MAH also has in-depth knowledge of the latest legislation and regulations within many different sectors, so you can always be sure that your finances are within the latest rules and best practices.

We also use our years of experience to give you business advice, to monitor your performance and to help you reach your goals.

                Fahed Rahman

                Social Media Executive

                Fahed is social media expert and he  brings a human touch to MAH as he has a bright and dynamic personality and enjoys meeting new people, as opposed to getting excited about accounts and tax legislation like the rest of us here.

                  What sets us apart from other London accountants or city firms?

                  First of all, our low overheads and efficiency savings mean that we can carry out complex work such as audit and corporation tax on a very cost effective basis.

                  Secondly, we provide a very personal service in a digital world. There are many firms who claim to be based in the city but are actually based far away and its difficult to get a meeting with them. Or you could be a client at a large or medium firm in the city but are one of their smaller clients and don’t get much attention. All of our clients are important to us and we’re always available for meetings or phone calls. We do use Skype and cloud technology but sometimes a face to face meeting is just easier when it comes to solving complex problems.

                  Thirdly, MAH is different to many London accountants thanks to the approach which we call ‘the MAH method’. We delve deep into your business to understand what your business is how it works. We also understand your goals and your pressures to really tailor our advice, judgement and practices to your business. The result of this approach is evident in every service we provide. Everything becomes more efficient, more accurate and ultimately provides better results.

                  After all, it’s the only real way to provide an accountancy service which is truly tailored to your business, and many clients who have switched to us can instantly tell the difference.

                  MAH method - this is what makes us a top firm of London accountants
