1. King Consultants Accountancy and Tax Solutions Ltd

Website: https://www.king-consultants-accountancy.co.uk/
Address: 142 Cromwell Road
Contact: 0800 669 6477
Hours: Monday-Sunday, 12:00 AM – 12:00 AM
Keeping your finances predictable is easy with King Consultants Accountancy and Tax Solutions Ltd. This is mainly thanks to their fixed-fee monthly subscription plans starting at £20 for self-assessment and £70 for limited companies.
Their team can help businesses navigate HMRC rules and identify allowable expenses that can reduce their tax bills. For landlords, they provide specialised property tax support, including help with mortgage interest relief and capital gains obligations.
On top of that, they handle personal and business tax returns and offer round-the-clock availability for clients who need quick answers outside regular hours.
However, their subscription plans require a firm 12-month contract, so you’ll need to commit for the full year.
He is super knowledgable, always on it and super responsive
Kyle straightened out my complicated company and personal tax affairs, cut my tax bill and got the whole thing on the right footing going forward. He is super knowledgable, always on it and super responsive and generous with his time. Great guy to work with. Strong recommend.

Prompt, clear, and informative
I recently had the pleasure of working with King Consultants Accountancy and Tax Solutions Ltd, and I must commend them, especially Cosmin, for their exceptional service. Cosmin’s expertise in accountancy and tax matters made a significant difference. His ability to simplify complex concepts and provide clear, actionable advice was incredibly helpful.
Cosmin was always prompt, clear, and informative in his responses, making what can often be a stressful process feel straightforward and manageable.
The personalised attention and tailored solutions provided by the firm significantly optimised our financial operations, positively impacting our overall efficiency and bottom line.

2. TaxSimba Group Limited

Website: https://taxsimba.co.uk/
Address: 4 Bloomsbury Square
Contact: +44 (0)20 3886 1234 | [email protected]
Hours: Monday-Friday, 8:00 AM – 6:00 PM
Filing your tax return can be stressful, but TaxSimba Group Limited makes the process easier with a guided digital platform. The team turns confusing tax jargon into simple questions, then a human specialist reviews everything for accuracy.
We spoke with a client who tested the setup, and they said the smooth, question-based interface made uploading their details fast and painless.
The platform also handles more complex tax profiles, including crypto traders, landlords, and expats with UK earnings. For added convenience, the team can set up your Unique Taxpayer Reference (UTR) number and help spot missed deductions.
Unfortunately, the service relies heavily on digital and in-app tools rather than in-person meetings. Additionally, ongoing year-round advisory is only available through the top-tier Elite plan.
Everything was handled with professionalism and care
I can’t recommend Tax Simba enough. From the initial consultation to filing my return, everything was handled with professionalism and care. The accountant took the time to understand my business, gave great advice, and ensured everything was filed correctly. Excellent service — thank you!

Highly recommended!

My consultant was Alisha, whom I can not prase enough
I was greatly relieved when after receiving 20k wrongly calculated tax bill for 2022-23 I passed my case over to UKPA. They saved me, in the end I didn’t have to pay anything at all. For a modest charge they recalculated my tax return anew and supported my case many months after, even long after I’d paid them i full. It only takes one online appintment for a 15 mins free consultation (it was with Yuki). The rest was a very smooth process based on email exchanges. My consultant was Alisha, whom I can not prase enough.

Hours: Monday-Friday, 9:00 AM – 6:00 PM
Expatriate Tax Services London Ltd provides a boutique service led by Managing Director Oliver Heslop. He brings over 25 years of experience from Deloitte, Ernst & Young (EY), and advising the US Embassy in London.
We spoke with a client who worked with him during a relocation from New York, and they said his deep understanding of dual-country tax treaties made the entire move feel seamless.
For expats, he provides guidance on the Foreign Income and Gains (FIG) rules and helps newcomers maximise their UK State Pension entitlements.
He also coordinates with trusted contacts across 80 countries, which can be useful if you have international tax needs.
But keep in mind that this is a solo boutique practice with no backup staff, so expect limited availability. Plus, his service isn’t designed for basic domestic-only UK accounting.
I would highly recommend Oliver
Oliver Heslop at Expatriate Tax Services London Ltd was tremendously helpful in advising me of my UK residence tax status over a number of years and also assisting me with my national insurance/ state pension backdated payments application. I would highly recommend Oliver for any similar support you may need.

Thanks to his deep knowledge of tax laws and regulations
I can’t recommend Oliver enough for the exceptional tax support he provided on our family’s tax matter. His expertise and keen attention to detail really stood out, turning a complex situation into something much easier to handle. He gave us clear and straightforward advice and was always there to answer our questions, no matter how small. Thanks to his deep knowledge of tax laws and regulations, we felt confident and well-supported throughout the entire process. Oliver’s dedication, professionalism, and willingness to go above and beyond truly made a difference for our family.

Address: 5th Floor International House, 2-4 Maddox Street
Contact: +44 207 491 9690 | [email protected]
Hours: Monday-Sunday, 8:00 AM – 10:00 PM
Facing an official audit or tax inquiry can be stressful, but WLH Tax specialises in serious tax dispute defence. Founder Warren Hyams brings over 25 years of experience from Klynveld Peat Marwick Goerdeler (KPMG) and Chiltern Plc.
He mainly helps clients handle Code of Practice 9 (COP9) fraud inquiries and voluntary disclosures. His team includes former HMRC tax inspectors and Big Four alumni who maintain direct communication with HMRC’s Fraud Investigation Service.
This experience also helps them guide clients through the Worldwide Disclosure Facility (WDF) for offshore assets and handle high-stakes Contractual Disclosure Facility (CDF) cases.
Just know that they work strictly as a tax investigation defence boutique, meaning they don’t prepare routine annual tax returns or handle basic bookkeeping.
His communication was exceptional
I highly recommend WLH Tax. My business faced significant challenges during a tax inspection, but after consulting with Trevor at WLH, he was able to drastically reduce our VAT bill. His communication was exceptional, explaining everything clearly and thoroughly, and he worked diligently to resolve the issue efficiently. A top-notch company that I would strongly recommend to anyone in need of expert tax support.

Thanks to their expertise and persistence
I worked with WLH Tax (WLH) on a very complex tax property dispute. After fighting it alone for four years, I was emotionally drained and defeated. Thankfully, I decided to seek professional advice, and WLH came highly recommended to me. From the beginning, Alan and Manoj were incredibly professional and knowledgeable, making me feel supported and in good hands. They were very empathetic to my situation and took the time to explain every step of the process. They were always available to answer my questions. Thanks to their expertise and persistence, we achieved an outcome that far exceeded my expectations.
