Securing a barrister mortgage can actually be more challenging than you might expect.
The UK buy-to-let market has undergone significant changes in recent years, with increased regulations and evolving requirements that landlords must meet to remain compliant. One area of growing importance is property energy efficiency. The UK government is pushing for higher Energy Performance Certificate (EPC) standards to combat fuel poverty and improve rental living conditions. This development places pressure on landlords to make costly property upgrades.
For landlords looking to raise capital for these improvements without disrupting their existing mortgage arrangements, a second charge mortgage buy to let offers an appealing financing option.
Here, will explore what a second charge mortgage is, its benefits for buy-to-let landlords, and how it can be used to fund property upgrades, especially in light of anticipated EPC legislation changes.

What is a Second Charge Mortgage?
A second charge mortgage is a type of loan secured against a property that already has a primary or "first charge" mortgage. The term "second charge" reflects the loan's repayment priority; in the event of default and repossession, the primary mortgage lender is paid first. Any remaining equity in the property is then used to pay off the second charge mortgage.
Landlords may opt for a second charge mortgage instead of remortgaging their buy-to-let property to access additional funds for various reasons. It offers flexibility, especially if the landlord has a favourable interest rate on the primary mortgage, significant early repayment charges (ERCs), or poor credit history.

Why Consider a Second Charge Mortgage for Buy-to-Let Properties?
Buy-to-let property owners often need to access funds for various purposes, including home improvements, debt consolidation, and business investments. A second charge mortgage allows landlords to raise funds quickly and without affecting the terms of their existing mortgage.
The key advantages of second charge mortgages for buy-to-let landlords include:
Access to Higher Borrowing Limits: Second charge lenders typically allow borrowing up to 100% of the property's total loan-to-value (LTV), making it a viable option for those with significant equity.
Protecting Existing Mortgage Terms: If a landlord has a low-interest primary mortgage or would incur high ERCs for remortgaging, a second charge mortgage enables additional borrowing without altering the original mortgage terms.
Flexible Loan Purposes: Funds can be used for various needs, including property upgrades, debt consolidation, business funding, and even tax bill payments.
Quick and Flexible Financing: Second charge mortgages can often be arranged within 2-3 weeks, allowing landlords to access the funds swiftly.
Using Second Charge Mortgages for EPC Upgrades
The New Minimum Energy Efficiency Standards
The UK government has announced plans to increase the minimum EPC rating for rental properties to band C by 2030, a significant rise from the current requirement of band E for private rentals. This change is part of a broader initiative to tackle fuel poverty and reduce carbon emissions.
Upcoming EPC Legislation Changes
Proposed Timeline: Originally slated for implementation by 2028, the deadline has now been extended to 2030, giving landlords a bit more time to comply.
Consultation Process: The government is expected to consult on these changes by the end of 2024, which will provide further clarity on specific requirements, potential exemptions, and enforcement.
Impact on Fuel Poverty: The changes are expected to lift over 1 million households out of fuel poverty, as tenants in properties with EPC ratings of D to G often face higher energy costs.
While the objectives are laudable, the new standards will likely require significant property upgrades for many landlords, especially those owning older properties.

How Second Charge Mortgages Can Help Fund EPC Upgrades
Landlords facing substantial costs to meet the new EPC standards can use a second charge mortgage as a way to finance the required improvements. Here’s how it can benefit them:
Access to Funds Without Disrupting Primary Mortgage: Many landlords may not want to remortgage their properties, especially if it means losing a favourable rate or incurring ERCs. A second charge mortgage allows landlords to raise the necessary capital while leaving the primary mortgage intact.
Flexible Loan Amounts and Repayment Terms: Second charge mortgage loans can range from £10,000 to a significantly higher amount, with repayment terms of up to 30 years, providing a manageable way to spread the cost of upgrades.
Improving Property Value and Tenant Appeal: By upgrading the energy efficiency of a property, landlords can not only comply with legislation but also potentially increase the property’s value and attractiveness to tenants. Properties with higher EPC ratings are more appealing due to lower energy costs.
Potential Tax Benefits: Depending on the nature of the improvements, landlords may be able to offset some of the upgrade costs against rental income for tax purposes.
Considerations for Landlords: Challenges and Solutions
While a second charge mortgage offers a practical solution for funding EPC upgrades, there are several considerations landlords need to be aware of:
Cost of Upgrades: Energy efficiency improvements, especially in older properties, can be expensive. Depending on the property's current EPC rating, upgrades may involve insulation, boiler replacement, window improvements, or even installing renewable energy sources such as solar panels.
Clear Guidance Needed: The upcoming consultation may clarify spending caps, exemptions, and other financial support measures. Landlords should stay informed about these developments to plan their upgrades accordingly.
Availability of Skilled Tradespeople: With more landlords needing to carry out upgrades, the demand for skilled tradespeople may rise, potentially leading to delays. It’s advisable to plan and book any required work as early as possible.

How Does a Second Charge Mortgage Work?
A second charge mortgage is an additional loan secured against your property, separate from your existing mortgage. It allows you to borrow against your home's equity without affecting your primary mortgage. The loan amount and terms are based on factors like your income, credit score, and available equity.
You'll make two separate monthly payments: one for your original mortgage and another for the second charge. In case of repossession, the primary mortgage takes precedence in repayment from the sale proceeds.
Here’s a hypothetical example of how the process can work:
Imagine a landlord in London who owns a Victorian-era buy-to-let property, currently rated EPC band D. With upcoming government plans to require all rental properties to reach at least EPC band C by 2030, this landlord needs to make improvements to meet the new standards.
The necessary upgrades include better insulation, installing a more efficient boiler, and fitting double-glazed windows—all of which could cost around a fair amount of investment.
Instead of remortgaging and risking a higher interest rate on the entire mortgage balance, the landlord considers an alternative: a second charge mortgage.
By taking out a second charge loan, they can secure the funds needed for the improvements without altering the terms of their existing mortgage. Our team at Hilo Finance can help arrange the £50,000 second charge loan, which is secured against the property and finalised in just three weeks.
With the funds in place, the landlord is able to carry out the upgrades, raising the property’s EPC rating from D to C. As a result, the landlord not only complies with the anticipated legislation but also increases the property's market value.

Alternative Financing Options for Landlords
While second charge mortgages are a viable option for many landlords, it's worth considering alternatives:
Remortgaging: For those who are not locked into a favourable rate or faced with high ERCs, remortgaging can be an option. However, this involves paying higher interest on the entire mortgage amount.
Bridging Loans: Short-term financing for immediate needs, such as rapid property upgrades. Bridging loans typically come with higher interest rates.
Further Advances: Some lenders allow additional borrowing on an existing mortgage, but the loan purpose may be restricted, and borrowing limits may be lower than with a second charge mortgage.
Next Steps for Landlords
With the UK government’s plans to improve EPC standards for rental properties, landlords need to start planning for the upcoming changes. Here’s how landlords can prepare:
Assess the Property’s Current EPC Rating: Determine the upgrades needed to achieve an EPC band C rating. Conducting a professional assessment can provide clarity on the required improvements and costs.
Consult a Mortgage Adviser: Speak with a specialist mortgage adviser to explore second charge mortgage options and other financing solutions.
Plan the Upgrades Early: Given the potential increase in demand for skilled tradespeople, it’s advisable to schedule the work well in advance of the 2030 deadline.
