Helpful accounting guides for UK business owners

FAQs on accounting services UK

Do I legally need an accountant for my limited company in the UK?

There is no legal requirement to appoint an accountant. However, limited companies must file statutory accounts with Companies House and submit Corporation Tax returns to HMRC. Many directors use an accounting firm to reduce risk, ensure accuracy and meet deadlines correctly.

What is the difference between bookkeeping and accounting services?

Bookkeeping records daily financial transactions such as sales and expenses. Accounting services interpret that data to prepare statutory accounts, tax returns and compliance filings. Most small businesses require both to maintain accurate reporting and meet UK regulatory requirements.

Can I switch to a new accounting firm mid-year?

Yes. You can change accounting services at any time. Your new accountant will contact your previous firm, obtain professional clearance and request relevant records. HMRC authorisation is also updated to ensure continuity of compliance and reporting.

Are your accounting services suitable for VAT-registered businesses?

Yes. We support VAT-registered businesses under Making Tax Digital rules. This includes digital record keeping, VAT return preparation and electronic submission to HMRC in line with statutory requirements.

Do you provide accounting services across the whole of the UK?

Our online accounting services support businesses throughout England, Scotland, Wales and Northern Ireland. Communication, document exchange and reporting are handled securely through cloud-based systems.
