A £200,000 bridging loan can give you different amounts of cash upfront, depending on how you pay interest.
With retained interest, the lender takes interest up front. With serviced interest, you pay it each month instead.
Here is how the two interest options affect the cash you receive and the payments you need to budget for.
What is retained interest?
With retained interest, the lender calculates the interest for the agreed period and deducts it from your loan at the start. You do not have to make monthly interest payments during this time.
This approach can help if you are buying a property that needs a lot of work before tenants can move in. While the property is empty, you will not have rent to cover bills.
With interest already paid, you have one less monthly cost to meet as the work gets underway.
What is serviced interest?
With serviced interest, you pay interest each month from your own funds. The lender does not take interest from the loan upfront, so you have more cash to complete your purchase. Fees may still reduce the amount you receive.
This can suit several types of property purchase, as long as you can cover the monthly payments:
- Tenanted buy-to-lets: Rent may help pay the interest. You still need funds to cover any gaps in rental income.
- Auction purchases: More cash upfront may help you meet a firm completion deadline. Check that the loan and your own funds cover the full purchase costs.
- Light refurbishments: You may have more cash left for repairs and updates. But you also need funds for interest while the work takes place.
What is the difference between retained and serviced interest?
The biggest difference is the timing of your interest payments.
With retained interest, the lender takes the interest out of your loan at the start to cover several months. You do not have to make monthly interest payments during this period, but you will receive less money for your purchase.
With serviced interest, you pay the interest every month. The lender does not take out interest at the start, but fees can still lower the amount you get. You'll need to have money ready for each payment, and you still owe the full loan amount.
Here is how the two options compare:
How do retained and serviced interest affect the amount you receive?
Let us compare both retained and serviced interest using a £200,000 loan at 1% per month over six months, before fees.
This rate matches GoGoProp’s published rate, but the example is not a quote. It assumes interest is charged on the original loan amount. At 1% per month, the interest is £2,000 a month, or £12,000 over six months.
The difference depends on when you pay:
- With serviced interest, you receive £200,000 before fees and pay £2,000 each month. At the end, you repay the £200,000 loan.
- With retained interest, the lender holds back £12,000 upfront to cover all six months. You receive £188,000 before fees and make no monthly interest payments during that period. You still repay the £200,000 loan at the end.
The £200,000 is your gross loan. This is the amount before deductions. Your net advance is the cash released after retained interest and any fees taken upfront.
Bear in mind, the lender may take an arrangement fee from the loan, add it to the balance, or pay it separately. Ask for a written breakdown showing what reaches your solicitor and what you owe at the end.
Which interest structure might you qualify for?
The options available depend on the lender’s checks and your circumstances.
Retained interest may suit a deal where funds for monthly payments are limited. But the upfront deduction leaves less cash for the purchase and any refurbishment works. Check that your own funds can cover the gap.
For serviced interest, you need to show how you will cover the monthly payments. Rent can help if the property is already let. If it is empty or needs work before tenants move in, you will need other funds.
The lender may look at:
- Monthly funds: Do you have enough cash to pay interest throughout the loan?
- Rental income: Is the property let, or will it be empty for part of the term?
- Planned works: How soon will the property be ready to earn rent?
- Repayment plan: How and when will you repay the loan?
Each lender has its own requirements. Not all ask for the same evidence or offer both interest options.
No matter which option you choose, your budget should allow for it:
- Monthly payments if you pick serviced interest, or
- Less cash at completion if you go with retained interest
How to choose between retained and serviced interest?
To choose between the two interest options, first figure out how much cash you need to buy the property. Then think about the loan costs and how you will pay it back.
With retained interest, you get less cash at the start, but you do not have to make monthly interest payments during that period. With serviced interest, you get more cash upfront before fees, but you will need to make a monthly payment.
Check each option against three stages of your property investment:
- Completion: Will the cash released (plus your own funds) cover the purchase, fees, and planned works?
- During the loan: Can you pay the monthly interest along with your other costs?
- Exit strategy: Will your planned mortgage, sale, or other source cover the final debt?
Once you have a clear budget, ask for a written breakdown of each quote. Then, compare:
- Cash released: How much will reach your solicitor after deductions?
- Monthly payments: How much is due, and when?
- Retained period: How many months of interest are covered upfront?
- Exit amount: What will you owe on your planned repayment date?
- Delays: What extra interest or fees could apply if you need more time?
The best interest option fits your purchase budget, monthly costs, and repayment plan.
What happens if you repay early or need more time?
Your sale or mortgage may complete sooner than planned. If it does, you could repay the bridge early. But do not assume you will get all unused retained interest back. Check the loan terms for any refund, minimum interest charge or early repayment fee.
If your sale or mortgage takes longer, you may need more time to repay. Ask whether the lender will allow an extension and what extra interest or fees could apply. An extension is not guaranteed.
Before you agree to the loan, check both possibilities:
- Repaying early: Will you get back any unused retained interest, and are there any minimum charges or fees?
- Needing more time: Can you extend the loan, and how would that change the amount you owe?
Build some room for delays into your repayment plan. Your planned sale or mortgage needs to cover the final debt, not just the amount you first borrowed.

Frequently asked questions
1. Do you get retained interest back if you repay a bridging loan early?
It depends on the loan terms. Check whether unused interest is returned and whether a minimum interest period applies.
2. Can you change from retained to serviced interest during the loan?
Only if the lender agrees to change the terms; ask before the loan starts.
3. Do you repay the whole bridging loan at the start if interest is retained?
No. Interest may be deducted upfront, while the capital remains due at the end under the loan terms.
4. How many months of interest can a lender retain?
It depends on the lender and loan terms. Ask how many months are covered and what happens if your loan runs longer.
5. Do you need rental income to pay serviced interest?
Not always, but the lender may assess how you will make monthly payments if the property has no rental income.
