Does a business loan affect your personal credit?

A business loan taken out by your limited company is recorded on the company's credit file, not yours. It can reach your personal credit in two ways: a credit search on you when the company applies, and a personal guarantee, which matters if the company can't repay and you then can't pay what the guarantee covers.

Signing a personal guarantee doesn't affect your credit score. The risk to your personal file starts if the company defaults and you then miss the payments you owe under the guarantee (British Business Bank).

A company's business loan sits on the company's credit file

A limited company is a separate legal entity, so a business loan it takes out in its own name is recorded on the company's credit file, not your personal one. Being a director of a company that falls behind doesn't, by itself, change that.

R3, the trade body for insolvency and restructuring professionals, says that even a company defaulting on a loan or entering insolvency 'will not have an impact on their personal credit record' for its directors, unless a personal guarantee changes that (R3).

Business lenders check the company's file, while a mortgage lender or a personal lender looks at yours. This is what usually ends up on each:

Borrowing in your own name works differently. If you take out a personal loan for the business or put company costs on a personal credit card, the debt is yours and can show on your personal file if you miss payments. The same goes for sole traders, who have no legal separation from their business.

Lenders often check your personal credit when the company applies

Many lenders check the directors as well as the company, so an application can leave a search on your personal credit file. Whether that matters depends on the type of search: a soft search has no effect on your score, and a hard search is visible to other lenders.

Experian, one of the UK's credit reference agencies, sets out the difference like this:

A personal guarantee is the main way a business loan reaches your credit file

A personal guarantee is your legal commitment to repay the company's debt yourself if the company can't. It's the main way a company loan can end up on your own credit file, but only once the guarantee is called and you can't pay what it covers.

While the company repays in full and on time, R3 says the guarantee 'will simply sit in the background and not come into effect'. If the company can't repay, it usually plays out in this order:

1. The company falls behind on repayments. That's recorded on the company's credit file.
2. The lender asks you, as guarantor, to pay. R3 notes that lenders typically ask for the amount owed on demand, and that you may be able to negotiate the repayment terms.
3. You pay what the guarantee covers. In that case, the guarantee doesn't usually leave a mark on your personal file.
4. You can't pay. A default can then be registered on your personal credit report, and the lender can take you to court. A county court judgment (CCJ) stays on record for six years unless you pay it in full within one month (GOV.UK).

Because a guarantee is a personal commitment, GOV.UK notes that your personal assets, such as your home, car, savings, and investments, could be used to settle the company's debt. If more than one director signs, the guarantee is often joint and several. That means each of you can be asked for the full amount, not just a share (GOV.UK).

How iwoca's personal guarantee and credit reporting work

If your company borrows from iwoca, the personal guarantee is what links the loan to you. Every new iwoca Flexi-Loan, needs one from at least one director.

Check these points before the company borrows

The questions that matter most for your personal credit are which search the lender runs, whether it needs a personal guarantee, and what that guarantee covers. Ask them before you apply.

Each answer tells you how far the loan could reach your own file:

• Which credit search it runs, on whose file, and at which stage
• Whether it needs a personal guarantee, and from which directors
• How much the guarantee covers, and whether it's limited or unlimited
• Whether the guarantee is joint and several if more than one director signs
• What happens if the company misses a repayment

Lenders lean harder on directors when the company has little credit history of its own, so a stronger company file helps. It's worth taking the time to build your company's credit score. iwoca Credit Compass, our business credit tool, lets you check your company's Equifax business credit score for free, plus four more scores, what's affecting them, and areas to improve.

Frequently asked questions

Does repaying a business loan on time help my personal credit?

Repaying a limited company's business loan on time builds the company's credit history rather than your personal score.

‍

Can I get a business loan without a personal guarantee?

Some lenders offer business loans without a personal guarantee, often for established companies with strong credit or for loans secured on business assets.

Does equipment finance affect my personal credit?

Equipment finance follows the same rule as a business loan. Hire purchase or leasing taken out by the company is recorded against the company, often with a director's guarantee, so it can reach your personal credit in the same way.
