Changes to Companies House filings: say goodbye to abridged accounts!

Anna Stubbs • September 9, 2025

The Economic Crime and Corporate Transparency Act became law in 2023. But as the goals of the Act progress, it’s bringing about a number of different changes to accounts filing.



The aim of the Act was to strengthen the role of Companies House and the UK business environment, support national security and disrupt economic crime. At the same time, the Act helps to deliver a more reliable companies register to underpin UK business activity.


These are all excellent aims. But one outcome of these changes to Companies House procedure is a major change to the way small and micro businesses file their accounts.

Let’s look in more detail at what this could mean for your accounts.

Filing of abridged accounts to be phased out


From 1 April 2027, Companies House will change the way that small and micro-entity companies file their accounts.


Currently, small, micro and dormant companies can file what are known as ‘abridged accounts’ with Companies House. These abridged accounts contain a simplified balance sheet and any notes needed to give context to the figures in the balance sheet.


From 2027, these abridged accounts will be replaced with more detailed accounts:

  1. Micro-entities will be required to file a copy of their balance sheet and profit and loss account.
  2. Small companies will be required to file a copy of the balance sheet, directors’ report, auditor’s report (unless exempt) and profit and loss account.

Companies will no longer be able to prepare and file ‘abridged’ accounts.

This means your micro, small or dormant company will need to prepare far more detailed accounts, including the inclusion of a profit and loss (P&L) report for the first time.


All filing of accounts to be made with commercial software

Another measure brought about by the Economic Crime and Corporate Transparency Act is the desire to modernise and digitise the UK’s filing routes.

From 1 April 2027, all accounts must be filed directly with Companies House using commercial software. All web and paper routes will be closed for accounts filings – but will remain open for other statutory filings.



Get ready for detailed accounts and commercial software filing

If you’re using cloud accounting software like Xero, QuickBooks or Sage, this change isn’t a significant hurdle. But if your company has been relying on Excel spreadsheets or paper ledgers, there’s now a real imperative to move to commercial accounting software.

Having adequate access to adequate funding is fundamental for any startup. In the early stages of getting your enterprise off the ground, you need working capital to reach the all-important minimum viable product (MVP) stage, rent premises and hire staff. But where does this initial funding come from? Let’s look at the UK Government's Start Up Loan scheme and the funding options it offers.

Cost-saving measures and how they drive profits

By Anna Stubbs • January 29, 2026
Question: “Can cost-saving measures in the business truly be a key driver of profits?” Running a profitable business is one of your key goals as an owner. Without profits, there’s no capital to reinvest in the business, no funds to grow the company and no money for your own dividend payment at the end of the financial year. So, is cost-saving the answer in these challenging economic times? Answer: “Careful management of costs is a fundamental way to improve your profit margins and profitability as an enterprise” Cost-saving measures will have a direct and measurable impact on your profits. This is usually achieved via two main mechanisms. Firstly, reducing your variable costs (like raw materials or direct labour) increases your gross profit margin. This retains more revenue from each sale you make as a business. Secondly, lowering fixed overheads (such as rent or software licenses) directly reduces the total expenses on your profit and loss statement, leading to a higher net profit. This immediate bottom-line improvement makes you a more financially healthy prospect to investors and lenders – which, in turn, can often make it easier to access funding and grow the business.
