“Lucy and the team are simply amazing. From the get-go they were friendly, attentive and easy to get hold of. In this modern-paced world, I needed an accountant with tools to contact them about queries and the ability to arrange the meeting myself. Their focused and concise interactions have enabled me to get my bookkeeping right first time and more importantly get on with what I am an expert in and grow my business.“

Your Questions, Answered
We know you might have some questions, and we’re here to make everything as clear and straightforward as possible. If you need more information, don’t hesitate to reach out—we’re always happy to help!
Yes, you can get an online accountant, and for many small businesses it is the simplest option. Everything is managed securely in the cloud, from bookkeeping to tax returns and payroll. You still get personal support and regular communication, just without face-to-face meetings. As a UK-based virtual accountant, we support directors and founders nationwide, making professional help accessible wherever you are based.
Yes, Xero is approved by HMRC for Making Tax Digital. This means you can use it to keep digital records and submit VAT returns in line with current rules. It is one of the most popular cloud accounting systems in the UK because it is reliable and easy to use. We support clients with setup, training and ongoing management to keep everything compliant and running smoothly.
The best online accounting software depends on your business, but Xero is one of the leading options for UK small businesses and limited companies. It is cloud-based, HMRC compliant and designed to simplify everyday financial tasks. The right setup makes a big difference. We support clients with choosing, setting up and managing their software so they stay organised and in control.
There are AI tools that can answer general accounting questions, but they cannot replace tailored support from a qualified accountant. Every business has different responsibilities and tax requirements, especially in the UK. While technology can be useful, it still needs human oversight to avoid mistakes. We combine modern tools with hands-on support, helping you stay compliant and confident in your numbers.
The 4 year rule usually refers to HMRC’s time limit for correcting tax matters. In many situations, HMRC can go back up to four years if there is an error in a tax return. The time frame can be longer if they believe there has been careless or deliberate behaviour. Staying organised and filing correctly reduces risk. We support clients in keeping their records accurate and compliant.
The cost of a personal accountant in the UK depends on the level of support you need. A straightforward self-assessment tax return may start from a few hundred pounds, while more complex situations can cost more. Clear pricing is important so there are no surprises. We offer fixed, transparent fees, giving you reliable support and peace of mind throughout the year.
