What mortgage products are available now for buy-to-let investors looking to remortgage early under the Mortgage Charter?
Quick Answer
The Mortgage Charter primarily addresses residential borrowers and does not extend to buy-to-let (BTL) mortgages. BTL investors looking to remortgage early must adhere to standard lender terms and conditions.
## Navigating BTL Remortgaging Outside the Mortgage Charter
It's important for buy-to-let (BTL) investors to understand that the government's Mortgage Charter, introduced to support borrowers facing rising interest rates, is primarily aimed at homeowners. While beneficial for owner-occupiers, it doesn't extend the same protections or early remortgaging options to BTL landlords. This means you won't find specific 'Mortgage Charter' products for early remortgaging as a BTL investor. However, this doesn't mean you're out of options. Landlords typically remortgage for new fixed terms, to release equity, or to adjust their portfolio strategy. The products available are standard BTL mortgage offerings from various lenders.
**Common BTL Remortgaging Products & Strategies:**
* **New Fixed-Rate Mortgages**: These are the most popular choice, offering payment stability. With the Bank of England base rate at 4.75% as of December 2025, typical BTL fixed rates range from 5.0-6.5% for two-year terms and 5.5-6.0% for five-year terms. Locking into a new fixed rate can provide certainty over your outgoings, essential for maintaining your cash flow. For example, a landlord with a £200,000 BTL mortgage currently on a variable rate might secure a new five-year fixed rate at 5.75%, helping them budget precisely.
* **Variable/Tracker Mortgages**: While less common in a rising rate environment, these products' rates fluctuate with the Bank of England base rate. They can be cheaper if rates fall but carry higher risk. Sometimes landlords opt for these as a short-term measure if they believe rates will soon decrease.
* **Interest-Only Mortgages**: The predominant product for BTL, allowing you to pay only the interest each month, keeping monthly payments lower. This frees up capital for other investments or property improvements. The capital is then repaid at the end of the mortgage term, often through the sale of the asset or refinancing.
* **Capital Repayment Mortgages**: Less common for BTL, but some investors choose these to reduce their overall debt. While monthly payments are higher, you're building equity more quickly.
* **Porting Your Mortgage**: If your existing lender has a good BTL product and you're buying another property, some lenders allow you to 'port' your existing mortgage product to a new property, or a portion of it. This can sometimes help avoid early repayment charges on the original deal, though it's not applicable for early remortgaging on an existing property.
* **Product Transfers**: Often the simplest option, where you switch to a new product with your current lender, usually at the end of your fixed term. This avoids legal and valuation fees and is a quick process.
## Pitfalls to Avoid When Remortgaging Your BTL
While remortgaging can be beneficial, several factors require careful attention. Neglecting these can lead to unexpected costs or difficulties securing a new deal.
* **Early Repayment Charges (ERCs)**: Crucially, remortgaging before your current fixed or discounted rate expires will almost certainly incur significant ERCs, often 2-5% of the outstanding loan. On a £200,000 mortgage, a 3% ERC would cost £6,000. For most BTL investors, the cost of an ERC outweighs any potential benefit from securing a slightly lower new rate, which is why lenders are hesitant to offer early remortgage options for BTL.
* **Stress Test Failures**: Lenders apply stringent stress tests. The standard BTL stress test requires your rental income to cover 125% of your mortgage payments at a notional rate of 5.5%. With current BTL mortgage rates between 5.0-6.5%, and the notional rate often reflecting this, many properties struggle to pass this test if rents haven't kept pace. A property generating £1,000 rent might only support a mortgage of around £181,818 at 5.5% (1000 / 1.25 / 0.055).
* **Ignoring Section 24 Implications**: Remember, since April 2020, individual landlords cannot deduct mortgage interest for income tax purposes. This means a higher tax bill on your rental income. When remortgaging, ensure your cash flow remains positive after accounting for this, especially if taking a new, higher rate mortgage.
* **EPC Requirements**: Lenders are increasingly scrutinising EPC ratings. While the current minimum is E, lenders are preparing for a proposed C rating by 2030 for new tenancies. If your property is below C, future remortgages or even continued letting might become difficult or require costly upgrades.
* **Impact of Corporation Tax**: If you're a limited company landlord, remember Corporation Tax is 25% for profits over £250k, or 19% for profits under £50k. While mortgage interest is deductible for companies, the overall tax burden should always be factored into your remortgage calculations.
## Investor Rule of Thumb
Only remortgage a buy-to-let property early if the savings from a new rate substantially outweigh any early repayment charges, or if significant equity release is essential for a strategic portfolio move.
## What This Means For You
The BTL landscape moves quickly, and understanding available products and potential pitfalls is crucial for your financial success. Most landlords don't lose money because they remortgage, they lose money because they do so without a clear understanding of the evolving market and their individual deal.

Steven's Take
It's a common misconception that the Mortgage Charter helps BTL investors in the same way it does homeowners. It simply doesn't. Your focus as a buy-to-let landlord needs to be on proactive portfolio management, ensuring your properties meet current and future stress tests, and having a clear long-term strategy for your mortgage products. Don't chase marginal rate differences if it means incurring hefty early repayment charges. Always run the numbers thoroughly, considering tax implications and future EPC requirements, and align your remortgaging with your overall investment goals, not just headline grabbing mortgage rates.
What You Can Do Next
Review your current mortgage product and note the end date of any fixed term to avoid early repayment charges.
Calculate the current Interest Coverage Ratio (ICR) for your property using the standard BTL stress test of 125% at a notional rate (e.g., 5.5%) to assess remortgage viability.
Obtain an updated EPC for your property and plan any necessary energy efficiency improvements to meet future standards.
Consult with a specialist buy-to-let mortgage broker to explore all available products and assess their fit for your portfolio and tax situation.
Thoroughly review all associated costs of remortgaging, including valuation fees, legal fees, and potential early repayment charges, before committing.
