Rules about Bookkeeping for a Limited Company in the UK

Here is a list of rules about bookkeeping explained for a limited company in the UK.

1. Keep Yourself Separate from Your Company

The first and most important rule of bookkeeping for a limited company is to realise that you are not your company. A limited company is an entity under its own legal carriage. Even if you’re the owner or director, the company operates under its own name. This implies that all the funds and assets, as well as all of your transactions, are company property and not yours personally.

For instance, if you send an invoice to a client and they make payment into the company’s bank account, then the money belongs to the company. It does not automatically turn into your own money. It’s money that you have removed from the business account without good documentation, such as paying yourself a salary or recording it as a loan, and that can be looked at as a misappropriation of company funds. Simply put, it is stealing money from your own business if you use it for personal reasons without explaining why. Therefore, separating personal and business finances at all times is crucial.

2. Open a Separate Bank Account for Your Company

Your limited company should have its bank account according to the first rule. As you are a separate legal entity, your money should not be mixed with my money. It is never acceptable to deposit company income into your personal bank account.

Nevertheless, sometimes you may pay for something for the company double over your own budget. In that case, the firm can pay you back. But this will apply only if the purchase was purely for business use. There is no way to reimburse you for personal expenses.

At first, having another account may seem a nuisance. But in practice, it makes bookkeeping much easier. When personal and business transactions are combined, bookkeeping is confusing and time-consuming. With a dedicated business account, counting income and expenses is much faster and more accurate.

3. Use a Director’s Loan Account for Personal Transactions

You are sometimes in a position where you pay for the company’s spending from your pocket. This usually occurs at the inception of a business, where the firm lacks sufficient cash. Because your limited company is its own legal entity, all personal funds you spend on its behalf are deemed a loan to your company. Already, the company owes you that amount, and that is a liability on its books now.

On the other hand, you may also take money from your company. If you do, you owe it back. In either case, whether you lend to the company or borrow from them, these transactions shall be shown clearly. Bookkeeping monitors this by means of a separate account referred to as the director’s loan account. This makes everything open, and nothing is missed.

4. Record Transactions by Date Earned or Incurred

Unlike sole traders, limited companies are not allowed to use cash-based accounting. This is because you can’t only use a bank statement to record income and expenses depending on when cash is received or sent from your account.

Accrual accounting is what limited firms are required to practice instead. Under this method, income is recorded upon the earning of the same, even if payment is received later, and payment for expenses is recorded at the time the expenses were incurred, regardless of the receipt of the expenses payment.

While discussing bookkeeping rules for a limited company, it is very important to record transactions in the appropriate financial year. This will influence your company’s tax and financial reports. Never tie your records to the paying dates—always to periods.

5. Make Accrual and Prepayment Adjustments

As limited companies work with accrual-based accounting, you must record income and expenses in the period to which they relate, not at the time when the money moves. This is frequently a matter of making changes to your accounts.

For instance, before going to bed on 31/03/2025. Your accountant produces the company’s account and tax return and sends you an invoice after that date. Even though you may not have gotten the invoice yet, the cost belongs to the year ending 31/03/2025. You have to account for this expense in that year. This is called an accrual.

Sometimes, the opposite happens. Imagine that in April 2025 you have an electricity bill for the period March 2025 – May 2025. Only one-third of that cost covers the year ending 31/03/2025. The rest should be rolled to the next financial year. This type of shift is known as prepaying.

6. Choose Between Excel and Accounting Software

Bookkeeping for a limited company is more detailed than for a sole trader. You may use Excel if you have only some transactions. But you need to remember that each transaction imparts an effect on two accounts. This is referred to as double-entry bookkeeping.

For instance, suppose your company purchases office supplies. You receive an invoice dated 10/01/2025. Record this impact on two things when you record this.

• Your office expenses increase.
• You also increase your accounts payable (money owed to the supplier).

What using Excel means is you have to hand-update both of them. If you miss out on one side, your books will not balance. If you are not sure how to do this, it is always better to consult a professional bookkeeper. Errors in bookkeeping can cause wrong tax returns and wrong annual accounts.

7. Keep Your Business Records Safe and Organised

Ensure you always keep proper ledger records of all business transactions. These include invoices, receipts, and bank statements. The limited company has to keep the records for at least six years after the end of the financial year in question.

Conclusion

Consequently, understanding the rules about bookkeeping for a limited company is essential to compliance and keeping records accurately. By adhering to these rules, you can make tax filings easier, improve your business operations, and keep the company’s finances on top. Good bookkeeping not only prevents legal problems but also gives great insight, which will encourage business growth.
