Cashback Mortgages Explained | That's Family Finance

Quick Answer

A cashback mortgage pays you a lump sum from the lender when your mortgage completes. While cashback can help with upfront costs, it should always be weighed against the interest rate, fees, and total borrowing cost.

Cashback Mortgages: How They Work and Are They Worth It?

If you're looking for a new mortgage or considering a remortgage, you may come across deals that offer cashback. These mortgage products provide a cash payment from the lender when your mortgage completes, which can help cover some of the costs associated with moving home or switching mortgage providers.

While cashback can be a valuable incentive, it's important to understand how these deals work and whether they represent good value overall.


What Is a Cashback Mortgage?

A cashback mortgage includes a cash incentive from the lender, usually paid shortly after completion. It can range from a few hundred to several thousand pounds and is available across first-time buyer mortgages, home mover mortgages, remortgages, fixed-rate mortgages, and tracker mortgages.


Why Do Lenders Offer Cashback?

Lenders use cashback to attract new customers and encourage switching. It can help offset solicitor fees, valuation fees, removal costs, Stamp Duty, and moving costs. However, the cashback is typically priced into the product — it rarely comes for free.


Are Cashback Mortgages Worth It?

It depends on your circumstances. A mortgage offering £1,000 cashback may have a higher interest rate than a similar product without cashback — over a fixed-rate period, the extra interest could outweigh the cashback received.

Factor to Compare Why It Matters
Interest rate Small differences compound over a 2–5 year fix
Monthly payments Real affordability impact
Arrangement fees £999–£1,999+ can cancel out cashback
Cashback incentive One part of the picture, not the whole
Early repayment charges Important if circumstances may change
Total cost over deal period Most reliable comparison figure
