Agreement in Principle Explained
An Agreement in Principle, also called a Mortgage Agreement in Principle or Decision in Principle, is a document from a mortgage lender that shows how much they may be willing to lend you.
It is not a final mortgage offer. It is an early estimate based on basic information about your income, spending, deposit, and credit history.
Simple meaning: An Agreement in Principle tells you the amount a lender might let you borrow before you make a full mortgage application.
Why Is an Agreement in Principle Important?
An Agreement in Principle is useful when you are looking to buy a home. It helps you understand your budget and shows estate agents or sellers that you are a serious buyer.
- It gives you an idea of how much you may be able to borrow.
- It helps you search for homes within your price range.
- It can make sellers take your offer more seriously.
- It can speed up the mortgage process later.
For example, if a lender gives you an Agreement in Principle for £250,000 and you have a £30,000 deposit, you may look at homes around £280,000.
Agreement in Principle vs Mortgage Offer
Many people confuse an Agreement in Principle with a mortgage offer. They are not the same thing.
| Feature | Agreement in Principle | Mortgage Offer |
|---|---|---|
| Stage | Early stage | After full application |
| Is it guaranteed? | No | Usually yes, if conditions are met |
| Checks required | Basic income and credit checks | Full financial checks and property valuation |
| Purpose | Shows what you may be able to borrow | Confirms the lender agrees to lend |
How Does an Agreement in Principle Work?
The lender checks basic details about you and then gives an estimate of how much they may lend.
Usually, you need to provide:
- Your income
- Your monthly spending
- Your deposit amount
- Your employment details
- Your address history
- Basic credit information
The lender then uses this information to decide whether you may qualify for a mortgage.
Does an Agreement in Principle Affect Your Credit Score?
It depends on the type of credit check the lender uses.
| Credit Check Type | What It Means | Effect on Credit Score |
|---|---|---|
| Soft credit check | A basic check that only you can see | Usually no effect |
| Hard credit check | A full check visible to other lenders | May affect your score slightly |
Tip: Before applying, ask the lender whether they use a soft or hard credit check.
How Long Does an Agreement in Principle Last?
Most Agreements in Principle last between 30 and 90 days. The exact time depends on the lender.
If it expires before you find a property, you may need to apply again.
Can an Agreement in Principle Be Refused Later?
Yes. An Agreement in Principle is not a final approval. A lender can still refuse your full mortgage application.
Common reasons include:
- Your income details do not match your documents.
- Your credit score changes.
- You take out new loans or credit cards.
- The property valuation is lower than expected.
- The lender finds problems during full checks.
Important: Do not make big financial changes after getting an Agreement in Principle, such as taking a new car loan or using large credit card balances.

- Choose a lender or mortgage broker.
- Fill in your basic details.

In many cases, you can get a result the same day.
