Feb 28, 2020 Report
Great team, excellent service. Sloane & Co are genuinely all the things you could wish for in an accountant without all the things you expect. They take care of things efficiently and very effectively, give really helpful advice, have an excellent manner, and most importantly understand our business. We don't see Sloane & Co as accountants, we see them as critical business advisors (who are also brilliant accountants).

We were so happy with Mark, Victoria and the team there that I recommended them to my partner, and they are now her accountants (who is equally as delighted as we are). I cannot recommend Sloane & Co enough. If they made lager, Carlsberg would almost certainly lose a strapline.

Mark Allen and his team at Sloane & Co have been our finance and taxation advisers from the beginning. They have helped us grow and have supported us through every twist and turn that we have encountered as a SME. We have recommended them to others and will continue to do so. Tax doesn't;t need to be taxing but you do need the best advice. They consistently deliver.
