What is a Mortgage Agreement?

A Mortgage Agreement is a binding legal contract between a lender and a borrower that secures a loan against real estate in England and Wales. It sets out how much you're borrowing, the interest rate, the monthly payments, the term, and what happens if you fall behind. It gives the lender a legal charge over the home until the loan is repaid in full.

Don't confuse the full agreement with a mortgage in principle (also called an agreement in principle or decision in principle). That earlier step is an indicative offer based on a credit check and shows roughly how much a lender might advance. It's popular with first-time buyers because it signals to an estate agent that your offer is credible, and a soft-search version can be run online without harming your credit score (a full application involves a hard credit check that can affect it). The agreement in principle isn't the binding contract. The Mortgage Agreement is the document you actually sign, and it must follow the FCA's MCOB lending rules, cover buildings insurance, maintenance responsibilities and early repayment options, and be registered as a charge with HM Land Registry to take full effect.

Worked example. A borrower takes a 250,000 loan against a house valued at 320,000 over a 25-year term at a fixed rate of 5.2%, repaying around 1,490 a month. The agreement records the 250,000 principal, the rate and term, the repayment schedule, the lender's charge over the property, buildings insurance obligations, and the fee (typically 1% to 5% of the balance) for repaying early. Miss the payments and the default clause sets out the repossession process.

The agreement stays in force for the whole life of the loan, so keep your signed copy and any policy documents to hand. If your circumstances change, for example a move to interest-only, a rate switch or a change of names on the title, those changes are recorded by varying the agreement or signing a new one rather than by a verbal arrangement.

Frequently Asked Questions

When should you use a Mortgage Agreement?

You need a Mortgage Agreement when buying a house or commercial premises with borrowed money in England and Wales. Most commonly this happens when purchasing through a bank or building society, but it's also essential for buy-to-let investments, private lending between individuals, or remortgaging an existing loan.

The agreement becomes central before you complete any purchase funded by a mortgage. It usually follows the mortgage in principle, once your full application and credit check are approved and the lender is ready to release funds. Before that stage, many buyers start by using an affordability calculator or a lender's app to estimate what they can borrow, then search for a lender and request an agreement in principle to guide their property viewings. Give yourself time here: an agreement in principle is usually valid for a set number of days, so view properties and make offers while it still stands. Get this right and you can register your ownership at the Land Registry and draw down the loan. Get it wrong and completion stalls. For related documents, browse our template types.
