Applications for personal guarantee backed business finance rose 63% year on year in the second quarter of 2026. Average loan value stayed above £300,000 for the second quarter running.
Two thirds more directors, in a single year, agreeing to stand personally behind their company's debt. This guide is what that number actually means, and what you are signing if you join them.

Section 01

The Purbeck data, explained

The figures come from Purbeck Insurance Services, reported through Credit Connect. Three qualifiers matter before the number does any work:

  1. It counts applications, not completed lending

    A rise in applications is a demand signal. It does not tell you money reached anyone's account.

  2. It counts personal guarantee backed finance specifically

    Not all small business borrowing. You will see it reported as the latter. It is not the same claim.

  3. Purbeck sells personal guarantee insurance

    The data comes from applications it sees, which makes it a real window on this corner of the market rather than a measure of UK SME lending as a whole.

Stated accurately it is still striking. What the money is for, on Q2 2026 applications:
36.2%working capital, the single largest category
20%investment in growth
1 in 4asset purchase, development or acquisition
£345,000average loan value for start-up businesses seeking personal guarantee insurance
Working capital leading is the line worth sitting with. Growth borrowing is a choice. Working capital borrowing is usually a response to something: a slow payer, a stock cycle, a cost that moved. When more than a third of personally guaranteed borrowing funds day to day trading, that is a cash flow signal rather than a confidence one.

Section 02

Why personal guarantees are back in fashion

A personal guarantee is one way a lender can reduce its risk when lending to a limited company, particularly where the business has a short trading history, limited assets or other characteristics that make the lending harder to underwrite.
Short trading history. Thin asset cover. A sector the lender finds difficult. A customer book concentrated in two or three names. Where the numbers do not quite carry the risk on their own, the guarantee is what closes it, and in a market where lenders have tightened, more applications land in that gap.
Which points at something useful: if a guarantee is being requested, that is information about how your application is being read. It is not a formality and it is not universal.

Section 03

What you are actually signing

A limited company normally separates the company's debts from the director's personal liabilities. A personal guarantee creates a separate contractual obligation that can make the director personally responsible if the company fails to repay. In broad terms, a director promises that if the company does not repay, they will.
What it covers, whether it is capped, whether it is joint and several with other directors, and whether it is secured against a personal asset are all matters of how the individual document is drafted. Two guarantees that look alike can behave very differently when called.
Four consequences that catch people out:

  1. It can outlive your involvement

    Resigning as a director does not automatically release a guarantee you have already given.

  2. It can be called before the company has finished failing

    Depending on wording, a lender may not have to exhaust its remedies against the company first.

  3. Uncapped is a real category

    Not every guarantee is limited to the original advance, and interest, costs and fees can sit inside the covered amount.

  4. If it is secured on property, that can include where you live

    Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

None of that makes a guarantee a bad idea. Giving one is frequently the reason a business gets funded at all, and directors sign them every day with their eyes open. It means it is a document to read properly and take advice on, not the last page of the pack.

Section 04

PG-backed finance versus Start Up Loans

These get confused, and they are not competing products so much as different scales.
Start Up Loans are government backed personal loans for business purposes. Up to £25,000 per founder, and up to £100,000 per business where there are multiple co-founders. Fixed rate. One to five years. No arrangement fee and no early repayment penalty. Available to UK businesses that are pre-launch or have been trading for up to 60 months, where the founder has not had one before.
Because they are advanced to the individual, the personal liability is built into the product rather than added by a separate guarantee.
PG-backed commercial finance is a different scale entirely, which the £300,000 average makes obvious. Commercial rates, commercial terms, and the guarantee is a separate document negotiated on the deal.
The rough decision line: if the amount you need is inside the Start Up Loans range and you qualify on trading months, start there, because the terms are more favourable than you will get commercially and the eligibility is published rather than discretionary. Above that range you are in commercial territory, and the guarantee question becomes live.
Myth 01

“Start-up means pre-launch”

One thing owners get wrong constantly: the 60 month trading window. People rule themselves out at year two believing “start-up” means pre-launch, when they have three years of eligibility left.

Section 05

Six questions before you sign

  1. Is the guarantee capped, and at what figure, including interest and costs?

  2. Is it joint and several with other directors, and what happens if one of them cannot pay?

  3. What specifically triggers a call on it?

  4. Is anything secured against it, and if so what?

  5. What would release it, and is there a route to review it once the business has more trading history?

  6. Is there a version of this deal that does not need one, and at what cost?

That last question is the one most people never ask, and it is the one most likely to change the outcome.

Section 06

Where we come in

We do not make credit decisions, we do not issue the money, and nothing here is a recommendation to give a personal guarantee. That is a decision for a director to take with proper advice.
What we can do is make sure the question is being asked in the right room. Lenders do not all want the same comfort, and a guarantee demanded in one place is not always demanded everywhere. Whether that is true in your case is knowable before anyone signs anything.

Whether a guarantee is required depends on which lender you ask. bizbritain puts the same case to 100+ lenders. You can compare what each one wants before you sign. Start the conversation on our funding for growth page.
