Personal Guarantees in Business Car Finance — What Directors Need to Know in 2026
💡 Key Takeaway
Personal guarantees explained for UK directors. Learn how PGs work in business car finance, the risks, and how to negotiate them in Reading and beyond.
If you're a company director applying for business car finance in 2026, there's a phrase you'll see on almost every agreement — personal guarantee. 🖊️
It sounds intimidating, and it should be taken seriously. A personal guarantee turns a business loan into a personal responsibility if your company can't pay.
At We Finance Your Asset in Reading, we explain every PG clearly before our clients sign — because no director should ever sign one they don't fully understand.
What Is a Personal Guarantee?
A personal guarantee (PG) is a written promise from a director or shareholder to repay a business finance agreement if the company defaults.
It's separate from your limited liability protection. If your company fails, the lender can pursue you personally for the outstanding balance.
PGs are extremely common on:
- Business hire purchase agreements
- Lease purchase and finance lease deals
- Stocking finance facilities
- Asset finance for vans, plant or commercial vehicles
Why Lenders Ask for Personal Guarantees
Most UK lenders want a PG when:
- The business is under three years old
- Trading accounts are limited or showing losses
- The asset value is high relative to turnover
- The director is the main decision-maker and shareholder
It gives the lender confidence that someone is personally accountable. In return, you usually get faster approval and better rates than an unsupported application.
What Happens If the Company Can't Pay?
If your business defaults and the lender calls in the guarantee, you become personally liable for the shortfall after the asset is sold.
That can include:
- Outstanding finance balance
- Interest, fees and recovery costs
- Legal costs if the lender goes to court
In serious cases this can affect your personal credit file, your home, and your savings. It's not something to sign without thinking it through. ⚠️
Limited vs Unlimited Personal Guarantees
Not all PGs are the same. The two main types in UK motor and asset finance are:
- Limited PG — capped at a fixed amount (often the deposit or a percentage of the loan)
- Unlimited PG — covers the full outstanding balance plus costs
If you're a director in Reading or Berkshire looking at a high-value vehicle, always push for a limited guarantee where possible. The right broker can negotiate this for you.
How to Reduce the Risk of a PG
You can rarely avoid a personal guarantee on small-business car finance, but you can reduce the exposure:
- Put down a larger deposit to lower the loan-to-value ratio
- Choose a shorter term so the balance falls quickly
- Ask for a cap or expiry date on the PG
- Explore PG insurance, which can cover up to 80% of your liability
- Use a broker who knows which lenders ask for the lightest PGs
Should Multiple Directors Sign?
For a multi-director company, lenders may ask for joint and several PGs. That means each director is liable for the whole amount, not just their share.
Make sure all directors take legal advice before signing. A simple shareholder agreement on how guarantees are shared internally can prevent fallout later.
