Alex Coggin | US & UK Taxation 5 stars for this review
Bambridge Accountants were increidble. In the time that we lived London, he and his team took exquisite care of our accounting and tax as we coordinated across the US and UK. They send you timely reminders and are incredibly responsive and helpful. A great service and I can't recommend them enough! December 2024
Gretchen Cline | US & UK Taxation 5 stars for this review
Alistair has helped me with my UK and US taxes for over a year now. He's always prompt to respond to all emails, and he's thorough and efficient with filing my taxes. He answers all of my questions clearly, and has helped me navigate a tricky tax situation and been reassuring, clear, and helpful throughout the process. October 2024
Jenny Hollander | US & UK Taxation 5 stars for this review
I have both US and UK income streams, and when I posted to Instagram about needing an accountant who could help me take care of both, three different friends recommended Bambridge. I've been delighted with their team—they make a complicated tax situation (and I am not someone who is good at taxes, to put it mildly) feel seamless. I'm grateful to have found them. January 2025
Kate Plaza | US Taxation 5 stars for this review
I have relied upon Bambridge Accountants for my US taxes for years. Alastair has been such a resource, they are now doing my UK taxes as well! Responsive and excellent care. Cannot recommend enough. May 2024
DeAnna Frank | US & UK Taxation 5 stars for this review
As an expat American living in London, tax season is a stressful time. My wife and I have been using Bambridge Accountants for all our UK and US tax needs, and it's been great. Great communication, fair prices, and super friendly... highly recommended! June 2024
Victoria Schofield | US & UK Taxation 5 stars for this review
If you find you are an 'accidential American' - born in the US because your parents were posted there - and realise that it is obligatory for you to file US tax returns, I can highly recommend Bambridge Accountants for their personal service, efficiency and courtesy March 2025
