What’s the difference between a Decision in Principle and a formal offer?
Quick answer — the short, practical distinction
A Decision in Principle (DIP) is a preliminary indication from a lender that your business is likely to be acceptable for finance based on basic information.
A formal offer is a legally binding document which confirms the lender’s exact terms, conditions and the amount they will lend after full underwriting and checks.
What exactly is a Decision in Principle (DIP)?
A Decision in Principle is sometimes called an eligibility check, indication of interest, or pre-approval.
It uses high-level information — such as turnover, time in business, loan purpose and a brief credit check — to estimate whether a lender would consider your business.
A DIP is usually quick to obtain and can be generated by a lender, a broker or a matching service like Best Business Loans.
It is useful for testing appetite without submitting a full application or providing detailed documents.
However, a DIP is conditional and non-binding; it does not guarantee a final offer will follow.
Different lenders treat DIPs differently, so the wording and validity period (often 30–90 days) will vary.
What does a formal offer mean in business finance?
A formal offer is the outcome of full underwriting and is usually issued after the lender has reviewed detailed accounts, bank statements and supporting documents.
It sets out the final loan amount, interest rate, fees, repayment schedule and any security or covenant requirements.
Once you accept a formal offer it becomes a legally binding contract subject to any pre-completion conditions being met.
Formal offers often include practical next steps such as legal charges, valuations or director guarantees if applicable.
Lenders will typically also include expiry dates and conditions that must be satisfied before funds are released.
If conditions are not met the lender may withdraw or amend the offer, so careful review and timely action are important.
Key differences: certainty, checks, timing and legal status
Legal status: a DIP is indicative and non-binding, while a formal offer is usually binding once accepted and conditions are satisfied.
Depth of checks: a DIP uses summary data and soft checks, whereas a formal offer follows full credit, affordability and due diligence checks.
Timing: DIPs are fast and helpful early in a decision, while formal offers follow weeks of underwriting in many cases.
Flexibility: a DIP can help you compare appetite across multiple lenders, but only a formal offer confirms the exact terms.
Use in negotiations: a DIP gives you negotiating leverage and confidence to proceed, but lenders and brokers will rely on a formal offer when planning drawdown.
Costs: obtaining DIPs is usually free, but formal offers may be accompanied by fees for valuations, legal work or arrangement fees.
Practical implications for business borrowers and brokers
When shopping for finance, use a DIP to quickly rule in or out lenders that are likely to be interested in your sector and lending need.
A DIP helps you decide whether to progress to a full application and to prepare the required documents for underwriting.
Brokers and platforms like Best Business Loans use DIPs to match your profile to lenders and reduce wasted effort.
For asset-heavy purchases you may want an early DIP before seeking specialised products such as asset finance.
For example, if you are considering equipment or vehicle funding, our matching process can connect you with suitable lenders who offer asset finance.

Steps to move from DIP to a formal offer and next actions
Step 1: Obtain a DIP to confirm lender appetite and gather realistic expectations on loan size and likely pricing.
Step 2: Compile full documents — accounts, management accounts, cashflow forecasts, and bank statements — required for underwriting.
Step 3: Submit a full application and expect a more detailed credit assessment, due diligence and possibly site visits or valuations.
Step 4: Receive, review and, if acceptable, formally accept the lender’s offer; ensure you understand all conditions and costs.
Step 5: Complete any pre-drawdown conditions such as signing legal documents, arranging insurance or providing additional security.
Following these steps reduces surprises and shortens the time between formal offer and drawdown.

Common questions (short answers)
Is a Decision in Principle legally binding? No — a DIP is provisional and does not commit the lender to lend.
Can a formal offer be withdrawn? Yes — if conditions in the offer are not satisfied or new information affects the lender’s risk decision.
How long does a DIP last? Typically 30–90 days, but check the lender’s specific validity period.
Will a DIP show on a credit file? Often lenders use soft searches for DIPs, but confirm with the lender; full applications use hard searches which can affect credit records.
Key takeaways
A Decision in Principle gives a quick, non-binding indication of lender appetite based on summary information.
A formal offer follows full underwriting and is the legally binding set of terms you accept to access funds.
Use a DIP early to save time, then prepare documents carefully to turn that DIP into a formal offer.
Best Business Loans can help you run quick eligibility checks, match you to appropriate lenders, and guide you toward a formal offer.
