Cashback mortgages are a popular choice for borrowers looking to inject some extra liquidity into their bank accounts at the exact moment they need it most. By providing a lump sum of cash upon completion, these deals can significantly ease the financial burden of moving home or setting up a new property.
In this guide, you will learn how cashback mortgages work, why the "free" money comes at a cost, and how to calculate if the incentive is actually worth it in the long run.
What is a cashback mortgage?
A cashback mortgage is a type of home loan where the lender provides a cash incentive as a reward for taking out the mortgage. This payment is typically made shortly after the mortgage completes and you have moved into your new home.
The amount you receive is usually either a fixed sum (e.g., £500 or £1,000) or a percentage of the total loan amount (e.g., 1% of the mortgage). Because this money is technically a rebate or incentive from the lender, it is currently considered tax-free for UK borrowers.
How do they work?
The process for a cashback mortgage follows the same path as a standard application, with the incentive triggered by the final drawdown of funds.
-
Fixed Cashback: This is the most common type, where the lender offers a set amount - often £250 to £500 - to help with legal fees or moving costs.
-
Percentage-based: More common with larger loans, some lenders offer a percentage (usually 0.5% to 1%). On a £300,000 mortgage, a 1% cashback would put £3,000 back in your pocket.
-
Payment Method: Lenders usually send the funds to your solicitor on completion day. Your solicitor will then either use it to pay their own fees and send you the remainder or transfer the full amount directly to your bank account.
While the "upfront" cash is attractive, these mortgages are almost always paired with Fixed or Tracker rates that are slightly higher than those on "no-incentive" products. Essentially, you are borrowing the cashback and paying it back with interest over the life of the deal.

Advantages and disadvantages
Cashback deals can be a lifeline for those who have exhausted their savings on a deposit, but they require a careful look at the "total cost" of borrowing.
|
Advantages |
Disadvantages |
|
Immediate Liquidity: Extra cash to buy furniture, appliances, or cover moving van costs. |
Higher Interest Rates: Lenders often "charge" for the cashback through a slightly higher interest rate. |
|
Legal Fee Help: Can effectively make your legal work "free" if the cashback covers the solicitor's bill. |
Clawback Clauses: If you remortgage or pay off the loan early, you may have to pay the cashback back. |
|
Simple Budgeting: Eases the "cash poor" period immediately following a property purchase. |
Limited Flexibility: Higher Early Repayment Charges (ERCs) are common on these products. |
Who are they for?
A cashback mortgage is typically a strong option for:
-
First-Time Buyers: Those who have used every penny for their 5% or 10% deposit and need cash for essentials like a fridge or bed.
-
Budget Remortgagors: People who want to switch lenders without any "out of pocket" expenses for valuation or legal work.
-
Borrowers with Immediate Expenses: If you know you need to perform minor repairs or decorating immediately after moving in.

How to find a cashback lender
The best way to evaluate a cashback deal is to look at the "Total Cost over the Term." A broker will compare the monthly payments of a cashback deal against a cheaper, non-cashback deal to see if the interest you save over 2 years is more or less than the cash you get upfront.
Note: Some lenders offer "Free Legals" OR "Cashback." If you have a trusted solicitor you want to use, taking the cashback is usually the better option. If you don't mind who does the paperwork, "Free Legals" can sometimes be worth more than the cash incentive.

FAQs
In most cases, the money is released on the day of completion. However, some lenders wait until you have made your first monthly mortgage payment before transferring the funds.
Yes! Many lenders offer cashback specifically to remortgage customers as an incentive to switch. This is often used to help cover the legal costs of changing lenders, making the switch "cost-neutral."
No. Once the money hits your account, it is yours to do with as you wish. You can use it for home improvements, buy a new sofa, or even put it back into your savings account.
Most cashback deals have a "lock-in" period. If you pay off the mortgage or switch lenders within the first few years (typically 2–5 years), the lender may demand that you repay the original cashback in full, on top of any Early Repayment Charges.
For individual residential borrowers, mortgage cashback is generally not considered taxable income by HMRC, as it is viewed as a discount on a commercial transaction.
