Company information in the public domain

Did you know you can monitor any UK company for free and get email alerts when key details change, which can help protect your own business from unexpected or unauthorised filings?

A significant amount of information about companies is available in the public domain from Companies House. Companies House is responsible for incorporating and dissolving limited companies, examining and maintaining statutory records, and making company information publicly accessible.

Much of this information is available free of charge, in line with the government’s commitment to open data. As a result, all publicly available digital information held on the UK register of companies can be accessed without cost.

The information available includes core company details such as the registered address and date of incorporation, details of current and resigned directors and officers, copies of documents filed with Companies House, mortgage and charge information, previous company names and insolvency records.

In addition, you can choose to monitor a company and receive email alerts whenever new documents are filed, such as changes to directors or registered office addresses. This can also be a useful safeguard for your own company, helping you to identify any unexpected or unauthorised filings at an early stage.

Aitch
I'm Aitch, the Founder and CEO of CIGMA Accounting Ltd. As a Chartered Management Accountant and as a CIMA member, I've spent more than 16 years helping businesses, entrepreneurs, landlords, and individuals with tax planning, accounting, and HMRC compliance. As a chartered accountant in London, I'm passionate about making complex tax matters easier to understand and helping clients make confident financial decisions. Over the years, I've advised start-ups, SMEs, established companies, and high-net-worth individuals across a wide range of tax and accounting matters. My expertise includes Corporation Tax, Self-Assessment, Capital Gains Tax, Inheritance Tax planning, R&D tax relief, capital allowances, international tax, and resolving complex HMRC compliance issues. Whether clients need a business accountant, tax accountant, or strategic tax advisor, my focus is always on delivering practical advice that creates long-term value. One of my specialist areas is Making Tax Digital (MTD). I've worked extensively with businesses preparing HMRC's digital reporting requirements, helping them move to cloud accounting, improve financial processes, and adopt technology that makes compliance more efficient. I regularly speak at Making Tax Digital roadshows, industry events, and educational sessions in collaboration with Zoho Books, sharing practical insights into digital accounting, tax legislation, and the future of the profession. Many business owners looking for the best accounting firm in London are not simply searching for an accountant they're looking for trusted advice, responsive support, and long-term value. That's the approach I've taken in building CIGMA Accounting. My team and I work closely with businesses across London and the UK, providing accounting services, tax advisory, bookkeeping, payroll, VAT, company accounts, and strategic tax planning tailored to each client's goals. Through this website, I share practical guidance on UK taxation, Making Tax Digital, HMRC updates, Corporation Tax, Self-Assessment, and business finance. My aim is to provide reliable, straightforward information that helps business owners understand changing regulations, reduce compliance risks, and make informed financial decisions with confidence.
