A Mortgage in Principle — also called an Agreement in Principle (AIP) or Decision in Principle — is a lender's indication of how much they may lend you, based on an initial affordability assessment and usually a soft credit check.
Why it matters
An AIP shows sellers and agents you are a serious, finance-credible buyer. In a competitive market it can be the difference between your offer being accepted and being passed over. For new build reservations, developers often expect to see evidence of your borrowing power before accepting a reservation.
How to get one
We arrange the AIP on your behalf, usually with a soft credit check that does not affect your credit score. It is not a binding offer, and it is not mandatory — but it is genuinely useful.
When you need it
Aim to have an AIP before you start viewing seriously or reserving a plot. The full mortgage application comes later, timed to the purchase — and for a new build, timed to the build programme and handover.
How long is it valid?
Most AIPs last 60–90 days. We refresh it if your search runs longer, and review rates closer to a full application so you get the most current deal.
