Personal Guarantees for Business Loans: What You’re Signing in 2026

What Is a Personal Guarantee on a Business Loan?

You sign a personal guarantee as a separate written promise: if your company can’t repay the loan, you pay it yourself. It’s the price most lenders charge for unsecured lending to a limited company.

Your limited liability won’t shield you here. The company structure normally keeps your cash flow clear of business debts, but the guarantee you sign hands the lender a direct route to you.

You’ll want to know the guarantee outlives the company. We’ve seen it survive liquidation, dissolution, and even your resignation as a director.

You’re only released when the lender confirms it in writing. Walking away from the shares doesn’t do it.

Which Lenders Require a Personal Guarantee?

You’ll be asked for a personal guarantee on almost every unsecured business loan to a limited company. Funding Circle, iwoca and Capify all require one as standard, and we’ve not seen an exception worth banking on.

Say you’re a director applying at month-end: the lender slides the guarantee into the loan pack with your application, not as an afterthought.

You’ll find the high-street banks decide case by case. Barclays, NatWest, HSBC and Lloyds take one at their discretion for a limited company, and a young business or a start-up will almost always be asked.

That’s the catch you sign up for.

Only a few routes skip it, and we cover those below.

Limited vs Unlimited: How Much You’re On the Hook For

You need to know whether the guarantee is limited or unlimited before you sign. An unlimited guarantee puts you on the hook for 100% of the debt, plus interest, default charges and the lender’s recovery costs.

You should watch for an “all monies” clause. It covers every facility the company holds with that lender, including your overdraft, the cards and the next loan, not just the balance you applied for today.

A limited guarantee caps your liability at a set figure, say £50,000 on a £100,000 facility. Lenders rarely offer a cap by default, so we’d negotiate for one every time.

You can cap it, but you can’t delete it.

Read your cap closely, too: many lenders write interest and legal costs as payable on top of the capped number.

What a Personal Guarantee Puts at Risk

You put your home, your savings and your income on the line. The guarantee reaches whatever the lender can recover against. Imagine the bank calling it while you’re chasing a late invoice to cover your payroll.

When you have several directors, the wording usually says “joint and several”. That lets the lender demand the full debt from any one of you, typically the one with the most home equity, then leave that person to claw back the rest.

Your spouse often has to sign too where you jointly own the family home. Lenders insist they get independent legal advice first, so no one can later argue they were pressured into signing without understanding the risk.

We’d treat that advice as protection for you, not a formality.

What Happens If the Company Can’t Repay

You’ll get a formal written demand first, usually giving you 7 to 14 days to pay. The company’s default or liquidation is the trigger that turns your guarantee into a personal bill.

Picture the demand landing on a Friday, the company already gone, and you reading that you owe the lot.

Ignore it and you’ll face a statutory demand, giving you 21 days to pay. An unpaid debt over £5,000 then lets them petition for your bankruptcy.

Don’t assume an unsecured guarantee keeps your home safe. The lender can win a judgment, secure a charging order against your property, and apply to force a sale.

A CCJ or bankruptcy stays on your credit file for six years, too.

Personal Guarantee Insurance: Is It Worth It?

You can insure part of the exposure with personal guarantee insurance, and for many directors it’s worth the premium. Purbeck is the established specialist, and we checked its 2026 cover directly.

On an unsecured loan the policy pays 60% of what the lender claims from you in year one, 70% in year two, and up to 80% from year three. A secured loan is covered at 80% from day one.

Premiums run from 1.6% to 5.2% of the guaranteed amount a year, set by your sector, credit and loan type. On a £100,000 guarantee that’s £1,600 to £5,200.

It won’t clear the debt for you.

Insurance reimburses you after you’ve settled with the lender. It shrinks the loss against your cash flow; it doesn’t cancel the guarantee.

How to Limit Your Personal Guarantee Exposure

You have more room to negotiate than the paperwork suggests, and the time to use it is before you sign. We’d never accept an unlimited guarantee as the opening position on your application.

You should push for five things. Cap the figure; apportion it to your shareholding so a 30% owner guarantees 30%; time-limit it so it falls away after clean repayments; insure the rest; and refuse cross-guarantees between sister companies.

Ask what actually triggers a call on you, and whether it’s truly “on demand” or only once the company formally goes under.

That’s the gap between a scare and a sale of your house.

Get every change you win in writing. A spoken promise from a bank manager isn’t worth the loan it sits beside.

Loans That Don’t Need a Personal Guarantee

You can avoid a guarantee entirely with the government Start Up Loans scheme. It takes no guarantee, no guarantor and no security, lends each founder up to £25,000 at a fixed 7.5%, and accepts businesses trading up to five years.

You’ll want the Growth Guarantee Scheme on your radar too. Lenders can still ask for a guarantee, but the scheme bars them from taking your family home as security. That’s a real protection for your cash flow planning.

Don’t misread its headline 70%, though. That guarantee backs the lender, not you; you stay 100% liable, and the lender calls your guarantee before the government covers any shortfall.

That’s the line that trips you up.

Are Personal Guarantees Regulated?

You get far less protection than you’d expect. Most lending to a limited company sits outside the FCA’s consumer-credit rules, so the breathing space and complaint routes that protect a personal credit card don’t reach your business loan.

Your protection is set by the £25,000 business-purpose line in the rules. A sole trader or small partnership borrowing £25,000 or less keeps FCA cover; almost everything to a limited company or LLP is unregulated, whatever the size.

So you’re leaning on contract law, not a regulator, if a guarantee goes wrong. That’s why we’d read the document, or have a solicitor read it, before it touches your credit file.
