Chartered Certified Accountants based in Hammersmith | Personal and business accounting services that make a difference. Accountancy is not just about figures, a good accountant can interpret them so they reveal something important about your life or the life your business. We are fluent in the language of personal, company and corporate accounts.

To us, these figures are more than mathematics, they tell us a story, a narrative that we can interpret in simple, clear terms what they say and what options they suggest for your future. As Chartered Certified Accountants, we go way beyond the bread and butter of filing tax returns on time. And that includes VAT.
Services
Personal taxation affects almost all of us in one way or another. It varies from person to person depending on the way the money is earned or gifted, the way it is spent, saved or invested or what is planned for it. Whilst Mr Taxman feels obliged to take as much of your money as he legally can, you will want to keep as much as you are allowed; the taxman is an expert and you are probably not.
As one tax loophole is closed another one opens. Since the introduction of corporation tax fifty years ago, its complexity has proliferated into a gigantic patchwork of rules and regulations that is time-consuming and an impediment to the smooth flow of business. We do not know it all, no one does.
The value of good accounting procedures are not always appreciated. Yes, they fulfil the compliance needs and they are essential in managing the company's finances. We see them as much more than that. A year-end review of your accounts reveal the health of the company and, through analysis, suggest ways to mitigate tax and strengthen the company's ability to plan for the future.
A good accountant does much more than process historical data; we can help your past performance become the blueprint to your company's future success through tax planning, management support, and business consultancy. However, our best advice can only come from knowing you on a personal level.

We want to know and your intentions and your expectations for your company: how you want to grow it (organically, by diversifying, merging or acquisition), how you want to plan your exit, how you won't take your rewards and so on.All these strategies demand good financial and tax advice. To encourage your trust and confidence in us, your primary contact will be with the founder, Harry Theocharous.
It is through close collaboration that your company can plan decisively for the future. You know your own business better than we do and we know about fiscal and tax matters. By pooling our resources we can analyse, budget, forecast and develop a plan for future growth. This depends very much on the relationship we have with each other.

I've worked with Harry and his team at Fortis for many years, using their accountancy services for both my business and self-assessment. I could not give them higher praise. Always approachable, knowledgeable, patient and, above all, competent! They are a great team and I would not hesitate to recommend them to anyone requiring accountancy services.

We have been clients of Harry and his team for six years. We approached them on a recommendation and have been delighted with their quality, responsiveness and professionalism at every point. I have no hesitation in recommending them to anyone. Harry is one of the very few business partners that I trust completely.

We have been working with Harry and the team at Fortis for four years and we consider them all very much part of our team. We receive a high quality, personal and friendly service and they have been great to help us create good quality management reporting within days of month end.
The team invested time with us to fully understand our business and they have helped us streamline our processes and worked with us to ensure all reporting meets our operational requirements.
We often recommend them to contacts looking for reliable, knowledgeable and friendly accountants.

Fortis saved my business from accountancy hell when our previous accountants had made a diabolical mess over a year and a half! I didn’t know enough to pick up on it sooner, but knew enough to make a switch. Fortis saved the day, meticulously tidying up for us, and making sure everything was done properly. They are a wonderful, client focused firm who genuinely care about doing the job to the highest standard. They’re willing to go above and beyond to offer helpful advice and to take on different projects. Recommend.

I can't praise Harry and his team highly enough. Professional, quick to act and very clear in their explanations and responses. They're completely on top of any changes to rules and regulations and have saved me a lot of time, effort and worry over the past few years. I would not hesitate to recommend them to anyone looking for an accountant

We've been using Fortis Accountants for two years and can highly recommend them. It's daunting starting a new business, but Harry and his team have provided personal support and thorough guidance. No question is too daft or too obscure for them to answer. It's nice in this world of generic online companies to be able to use a local firm who really do deliver a professional and responsive service.
