Know when your fixed rate ends.

When a fixed deal ends, most mortgages move to the lender's standard variable rate, which can be noticeably higher. We'll remind you in good time to look at your options.

Common questions

Is Mortgage Owl free to use?

Yes. All guides, calculators and the fixed-rate reminder are free.

Is this financial advice?

No. Mortgage Owl provides general educational information only. For a recommendation based on your circumstances, speak to an FCA-authorised mortgage adviser.

How does the fixed-rate reminder work?

You tell us when your deal ends and we email you 6 months, 3 months and 1 month beforehand, so you have time to compare options.

How much can I borrow for a mortgage?

It depends on the lender and your circumstances. Many lenders lend up to around 4 to 4.5 times your income, and some may go higher in certain cases. Lenders look at your income, outgoings, credit history and deposit to check what you can afford. More on MoneyHelper.

How much deposit do I need to buy a house?

You usually need at least 5% of the property price. A bigger deposit, such as 10%, 15% or more, normally gives you access to lower interest rates and more lenders.

When should I start looking for a new mortgage deal?

Around six months before your current deal ends is a sensible time to start. Many lenders let you secure a new rate up to six months in advance, which can help you avoid moving onto your lender's standard variable rate.
