Mortgage types explained

The product type decides how your monthly payment behaves for the next few years. Here is what each one means in practice.

Fixed rate The interest rate stays the same for a set period, typically two, three, five or ten years.

Your payment does not change for the fixed period however the Bank of England base rate moves. At the end you move on to the lender's standard variable rate unless you remortgage.

Fixing for longer buys certainty at the cost of flexibility: early repayment charges usually apply if you leave during the fixed period.

Good for
Anyone who wants to know exactly what they will pay each month.
Watch out for
Early repayment charges, and the jump to the variable rate if you do nothing at the end.
Tracker The rate follows the Bank of England base rate plus a set margin, so it moves up and down with it.

If the base rate falls your payment falls, and if it rises so does your payment. Some trackers have a floor below which the rate will not drop.

Trackers often have lower or no early repayment charges, which suits people who may sell or overpay.

Good for
People comfortable with some variation who want flexibility.
Watch out for
Payments can rise quickly if base rate rises. Budget for the higher figure.
Standard variable rate The lender's default rate, which you move on to when a fixed, tracker or discount period ends.

Each lender sets its own standard variable rate and can change it at any time. It is usually well above the deals on offer, which is why most people remortgage before their deal ends.

Good for
Short periods only, for example while a sale completes.
Watch out for
Paying it for months or years without noticing is the most common expensive mistake we see.
Discount variable A set discount off the lender's standard variable rate for an introductory period.

Because it is tied to the lender's own rate rather than to base rate, the lender can change it independently. The discount is fixed; the rate underneath it is not.

Good for
Borrowers who want a lower starting rate and accept the uncertainty.
Watch out for
The rate can rise even when base rate does not.
Offset Your savings are set against the mortgage balance so you pay interest only on the difference.

With £30,000 in a linked savings account and a £250,000 mortgage, you pay interest on £220,000. The savings stay accessible and earn no interest of their own.

Offset mortgages suit people with meaningful savings or irregular income who still want the money within reach.

Good for
Savers, the self-employed and higher-rate taxpayers.
Watch out for
Rates are often a little higher than the equivalent standard deal, so the savings need to be large enough to make it worthwhile.
Interest only You pay only the interest each month and repay the full loan at the end of the term.

Monthly payments are lower, but the capital is untouched, so you need a credible plan to repay it: selling the property, investments, a pension lump sum or savings. Lenders will ask to see that plan.

Interest only is common on buy-to-let mortgages and less so on residential ones, where lenders apply stricter criteria.

Good for
Landlords, and residential borrowers with a clear repayment strategy.
Watch out for
At the end of the term the whole loan is due. Your home may be repossessed if it cannot be repaid.

Questions about mortgage types

Which type of mortgage is best?

There is no best type, only the one that fits how you want your payments to behave. Someone who needs certainty leans towards a fixed rate; someone who may sell or overpay soon may prefer a tracker with low early repayment charges. We talk it through before recommending anything.

What happens when my fixed rate ends?

You move on to the lender's standard variable rate unless you remortgage or switch to a new product with the same lender. We contact clients about six months before a deal ends so that never happens by accident.

Can I overpay on a fixed rate mortgage?

Most lenders allow overpayments of up to ten per cent of the balance each year during a fixed period without an early repayment charge. Above that a charge usually applies. Trackers are often more flexible.
