What Does Filing Full Accounts Mean?
Companies that file full accounts at Companies House are required to include a complete profit and loss account, balance sheet, notes to the accounts, and often a directors' report and auditors' report. This level of disclosure is mandatory for large companies (turnover over £36m), and for most companies that undergo a statutory audit. Some smaller companies also voluntarily file full accounts for reasons of credibility, investor requirements, or banking covenants.
Full accounts filers are the most transparent segment of the UK register - their financial performance, profitability, debt levels, and asset base are all publicly available in their annual filing. This makes them the most data-rich target for financial analysis and commercial prospecting.
Why the 'Full Accounts' Category Contains Medium AND Large Companies
In practice, the formal 'medium accounts' filing type is rarely used in the UK. Most companies above the small threshold file full accounts because: their lenders or investors require full accounts as a covenant condition; their statutory audit obligation means full accounts are prepared anyway; or they choose full accounts for credibility purposes. As a result, the 'full accounts' category encompasses most genuinely medium-sized businesses (turnover £10m-£36m) alongside the truly large enterprises.
Who Targets Full Accounts Filers?
- Enterprise software vendors - companies at this scale typically use ERP systems, CRM platforms, and enterprise tools rather than SME software
- Management consultants and advisory firms - established businesses with real complexity need strategic advice and professional services beyond basic accountancy
- Commercial property agents - companies at this scale typically occupy significant premises and have real property decisions to make
- Recruitment and executive search firms - companies of this size hire regularly and at senior levels, making them high-value recruitment clients
- Commercial lenders and asset financiers - medium and large businesses have substantial financing needs beyond SME lending products
- HR and payroll platforms - companies with 50-500+ employees need enterprise HR, payroll, and workforce management tools
What Financial Data Is Available for Full Accounts Filers?
Unlike micro-entities and most small companies (which can file without a profit and loss account), full accounts filers disclose: turnover, gross profit, operating profit, net profit, total assets, net assets, cash and cash equivalents, creditors, debtors, and employee numbers. This makes them uniquely data-rich for credit assessment, financial benchmarking, and commercial due diligence.
Frequently Asked Questions
How many UK companies file full accounts?
Over 500,000 active UK companies file full or group accounts at Companies House. This includes the genuine large company population (turnover over £36m), most medium-sized businesses, group holding companies, and smaller companies that voluntarily file full accounts.
Why does the 'medium' accounts type show so few companies?
The formal 'medium' accounts label is rarely used in the UK, even by companies that legally qualify as medium-sized. Most medium-sized businesses file full accounts instead, because their audit requirements, banking covenants, or investor expectations mean they prepare full accounts regardless. This is why 'full accounts' is the dominant category for companies above the small threshold.
Can I see the actual turnover of full accounts filers?
Yes, for most full accounts filers. The profit and loss account is a required part of full accounts, which means turnover is publicly disclosed in the Companies House filing. This is a significant advantage over small and micro company data, where turnover is typically not available.
Are full accounts filers typically audited?
Most but not all. Mandatory audit is required for companies above two of three large company thresholds: turnover over £10.2m, balance sheet over £5.1m, more than 50 employees. Companies above these thresholds are usually audited, and the audit report forms part of their public accounts. Some smaller companies are also audited voluntarily or by investor requirement.
How does size affect the B2B sales cycle when targeting these companies?
Larger companies have longer, more complex sales cycles. There are typically more stakeholders, formal procurement processes, and evaluation committees. The deal values are higher, as are the customer lifetime values, but the time from first contact to closed deal is significantly longer than with small or micro-entity businesses. Targeting full accounts filers makes most sense for enterprise B2B products with high contract values.
Can I filter full accounts filers by sector and financial health?
Yes. The Companies prospecting search at /companies lets you filter by size band alongside sector, location, trajectory (growing or shrinking), and financial position (positive or negative net assets). You can find, for example, full accounts filers in the technology sector with positive net assets that have been growing - a high-quality enterprise prospecting list.
