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!
For a limited company, accountancy fees in the UK typically range from £150 to £300+ per month, depending on the complexity of your business and the level of support required. While some providers offer entry-level services, our tailored packages start from £100 per month, giving you a strong foundation with room to grow. You’ll benefit from clear pricing, along with proactive and reliable support as your business develops.
While it’s not a legal requirement, most limited companies benefit hugely from having an accountant. There are strict filing deadlines, tax rules, and reporting obligations to manage. An accountant helps you stay compliant, avoid penalties, and make tax-efficient decisions. We work closely with directors to keep things simple, save time, and ensure everything is handled correctly.
Yes, you can prepare and file your own accounts, but it can be time-consuming and complex if you’re unfamiliar with HMRC and Companies House requirements. Mistakes can lead to penalties or missed tax-saving opportunities. Many directors choose to work with us so they can focus on running their business, while also having clear visibility of their finances, making it easier to plan ahead and set aside money for tax.
Accountants support limited companies with annual accounts, Corporation Tax returns, bookkeeping, payroll, and VAT. Beyond compliance, we also provide advice on tax efficiency, dividends, and business growth. Our goal is to give you clarity and confidence in your finances, helping you make informed decisions while ensuring you meet all your legal obligations.
You don’t legally need an accountant, but having one can make a significant difference. Limited companies face more complex rules than sole traders, and getting things wrong can be costly. We help directors stay organised, meet deadlines, and reduce their tax bill where possible, giving you peace of mind and more time to focus on growing your business.
