Starting a property search often requires proving to estate agents that you have the financial backing to make an offer, making an agreement in principle a crucial first step. An agreement in principle—sometimes called a decision in principle—provides a written estimate of how much a lender might be willing to lend you based on a preliminary review of your income and outgoings.
Reviewing how the application process works helps you gather your financial figures before submitting your details to the bank. Understanding basic eligibility criteria and credit check impacts ensures you can approach house viewings with confidence without affecting your credit rating.

An HSBC mortgage agreement in principle is one of the steps in the bank loan application process that helps you figure out how much mortgage you can get, for how long, and what payments you will make.
Such an application will not affect your credit score, and it can be completed online in 5 minutes on the HSBC's website in the Borrowing – Mortgages section.
To be eligible you should:
- be a resident of Great Britain and have an age of 18 or over
- get a periodic revenue in GBP
- you are not a military
- buy-to-let mortgages and help-to-buy do not participate in the program
To get an HSBC mortgage decision in principle, you will need to fill in your personal and financial details.
As the bank has given you a positive decision on an HSBC agreement in principle, you can count on the stated conditions within 60-90 days from the date of its issuance.
Pro-Tip from Olesya Krasavtseva, Content Editor at Prostobank Consulting: Keep your income figures and expenditure estimates consistent across your agreement in principle and your eventual full mortgage application. Discrepancies between the estimated budget you provide during the preliminary AIP stage and the actual financial documents submitted later can cause underwriting delays or lead the bank to revise your maximum borrowing limit downward.
Frequently Asked Questions
Does getting an HSBC mortgage agreement in principle leave a negative mark on my credit report?
When you apply for a standard agreement in principle, the bank conducts a soft credit check to review your borrowing history and financial stability. Soft searches are only visible to you and do not affect your credit score or appear on searches carried out by other commercial lenders. However, once you transition from an AIP to a formal, binding mortgage application, the bank will perform a hard credit check, which leaves a permanent note on your report. Review your credit file independently before starting your property search to ensure your personal details and electoral roll registration are up to date.
How long is an agreement in principle valid for after it is issued?
Agreements in principle are temporary estimates valid for a limited period—typically between 30 and 90 days depending on the lender's policy—because personal financial circumstances and interest rates fluctuate over time. If your house hunt takes longer than expected and your certificate expires before you make an offer on a property, you will need to submit a fresh application with updated financial details. Contact customer support or log back into the portal to request a renewal if your certificate lapses during your property search.
