Fernside Accounting is a new practice — we don't have a wall of testimonials and we won't pretend otherwise. What we do have is an MIAB-qualified founder, technical oversight from a Chartered Certified Accountant (FCCA) and Chartered Tax Adviser (CTA), and a deliberate decision to keep prices fair and process tight. Here's what we commit to.
Every set of accounts and every tax return is reviewed by a Chartered Certified Accountant and Chartered Tax Adviser before it goes out. Most online accountants at our price point don't offer that level of oversight.
Five fixed monthly packages — from £30/mo for sole traders to £325/mo for established businesses — published on this site. Not buried behind a "request a quote" form.
If your situation needs deeper tax expertise — R&D claims, restructuring, EIS/SEIS, HMRC investigations — we don't bluff it. We refer to our sister firm The Tax Lead and you get the right specialist at the right price.
Monthly fees, monthly notice. If you ever want to leave, we don't make it hard. We're confident enough in the service to bet on retention through quality, not lock-in.
No glossy testimonials. No paid endorsements. Just an honest invitation: book a free 20-minute call, and judge us on the conversation. If it's a fit, you'll know. If it isn't, you'll have spent 20 minutes getting a clearer view of your own tax position either way.
