My current property has an existing mortgage with an Early Repayment Charge until next year. Is it worth paying the ERC now to remortgage and release equity for a new project, or should I wait? How do I calculate if it's financially viable?
Quick Answer
Assess the Early Repayment Charge (ERC) against the project's potential returns and immediate costs like higher interest rates or missed opportunities to determine if paying it now is financially viable.
## Deciding Whether to Pay an Early Repayment Charge to Remortgage
This is a classic dilemma for property investors looking to grow their portfolios. You've got capital tied up in equity, a new project on the horizon, but an Early Repayment Charge (ERC) standing in your way. Deciding whether to pay that ERC or wait it out requires a thorough financial calculation, not just a gut feeling.
### Understanding the Early Repayment Charge (ERC)
An ERC is a fee charged by your current lender if you pay off or remortgage your loan before a specified period, usually the end of a fixed or discounted rate term. The charge is typically a percentage of the outstanding mortgage balance, sometimes tiered, for example, 3% in year one, 2% in year two, etc. You need to get the exact figure from your current lender.
### Why You Might Consider Paying the ERC Now
1. **Opportunity Cost:** The biggest driver here is the new project. If it's a solid deal, offering strong returns, waiting a year could mean missing out entirely. Property deals, especially good ones, don't hang around.
2. **Market Conditions:** Are property prices rising quickly in your target area? Waiting could mean the new project becomes more expensive, potentially eroding your profit. Similarly, if rental demand is high, delaying means missing out on a year of rental income.
3. **Mortgage Rate Projections:** While current rates are around 5.0-6.5% for buy-to-let mortgages, if you anticipate rates climbing significantly by next year, locking in a slightly higher rate now, even with an ERC, might be better than facing much higher rates later. The Bank of England base rate is 4.75% as of December 2025, and future movements are always a consideration.
4. **Equity Release Potential:** If the equity release means you can buy two properties instead of one, or a larger, more profitable property, the ERC might be a justifiable cost.
### The Calculation: ERC vs. Opportunity
This is where the numbers come in. You need to weigh the *cost* of paying the ERC against the *benefit* of proceeding with your new project sooner.
#### Step 1: Calculate the Exact ERC
Contact your current mortgage lender and get the precise ERC figure. They will tell you exactly how much it will cost to exit your mortgage today.
#### Step 2: Estimate the Costs of Delaying
If you wait, what are you losing? This is the 'opportunity cost' and is harder to quantify but crucial.
* **Lost Profit on New Project:** If your new project is, for example, a flip with a projected profit of £30,000, waiting a year means you've potentially lost that £30,000, or at least deferred it.
* **Lost Rental Income:** For a buy-to-let, estimate the annual rental income less expenses for the property you'd acquire. For example, if a new property generates £1,000 per month gross, that's £12,000 lost in potential rent over a year.
* **Potential Price Increases:** How much might the new property increase in price by next year? If it typically appreciates by 5% annually and the property costs £200,000, you could be looking at an additional £10,000 to pay.
* **Impact of Section 24:** Remember, for individual landlords, mortgage interest relief is not deductible. If the new property is owned personally, the tax implications of the income and finance costs will affect your net profit calculation.
#### Step 3: Compare and Decide
Once you have the ERC figure and your estimated 'cost of waiting', you can make a more informed decision.
**Example:**
Let's say your outstanding mortgage is £150,000 with a 2% ERC, equating to £3,000.
* Your new project, a buy-to-let, is expected to generate £800 net profit per month after all costs (including the current 5.0-6.5% BTL mortgage rates and accounting for Section 24). Over a year, that's £9,600 in profit you'd miss.
* The property you're eyeing is well-priced. Local agents suggest similar properties are rising by 3% annually, so the property could cost an additional £6,000 next year.
In this scenario, waiting could cost you £9,600 (lost profit) + £6,000 (price increase) = £15,600. The ERC of £3,000 suddenly looks like a much smaller sum when viewed against a £15,600 potential loss.
### Other Considerations
* **Lender Fees:** Don't forget new mortgage arrangement fees, valuation fees, and legal costs associated with remortgaging. These add to the immediate outflow.
* **SDLT:** When buying the new property, remember the additional dwelling surcharge means you'll pay 5% on top of the standard rates. If your new property is £300,000, for example, you'd pay 0% on the first £125k, 2% on £125k-£250k, and 5% on £250k-£300k, plus the 5% surcharge on the entire amount. This significantly impacts your upfront costs.
* **Stress Testing:** When seeking a new BTL mortgage, lenders will still stress test your income coverage. At a 125% rental coverage at a 5.5% notional rate (ICR), you'll need to ensure the rental income from the new property comfortably covers your mortgage payments.
* **EPC Requirements:** Note that the minimum EPC rating for rentals is currently E, but proposed changes suggest C by 2030. Ensure your new potential purchase meets current and likely future standards, or factor in upgrade costs.
Ultimately, this decision is about comparing tangible costs (ERC, new mortgage fees) with the less tangible but highly impactful costs of missed opportunities and market movements. Do your homework, get concrete figures, and run the calculations.
Steven's Take
Look, I've seen countless investors get tripped up by this. The ERC might look like a hefty chunk of change upfront, but you've got to think like a business owner. What's the cost of *not* acting? Missing out on a cracking deal that could generate £10k, £20k profit, or solid rental income for a year, is often far more expensive than paying a £3k or £4k ERC. Don't let a fixed cost blind you to variable opportunities.
Get the exact ERC figure from your lender, then project the profit and income from your potential new project over the next year. Factor in any known property price increases in the area you're looking at. Seriously, write it down, see the figures side-by-side. If the 'cost of waiting' outweighs the ERC and associated remortgage fees, then it's a no-brainer. Sometimes, you've got to spend money to make money, and releasing that equity quicker can be the smartest move for your portfolio's growth.
What You Can Do Next
Contact your current mortgage lender to get the precise Early Repayment Charge (ERC) figure and confirm its expiry date.
Quantify the potential profits or rental income you stand to gain from your new property project over the next year if you proceed immediately.
Estimate the 'cost of waiting' by considering potential property price increases, lost rental income, and any other market factors if you delay by a year.
Obtain quotes for new mortgage products, factoring in arrangement fees, valuation costs, and legal fees associated with remortgaging and the new purchase.
Compare the total immediate costs (ERC + new mortgage fees) against the total estimated financial loss or missed opportunity of waiting. Proceed if the immediate costs are comfortably outweighed by the benefits of acting now.
