My current BTL mortgage fixes in 6 months. I want to release equity to refurbish another property. Should I product switch with my current lender or remortgage elsewhere? What are the pros and cons for speed and fees?
Quick Answer
Choosing between a BTL mortgage product switch or a remortgage involves weighing speed and fees against better rates and equity release. A product switch is faster, but a remortgage offers access to the wider market, potentially better rates (currently 5.0-6.5%), and capital raise options.
## What are the Main Differences Between a Product Transfer and a Remortgage?
When your current buy-to-let (BTL) mortgage product expires, you have two primary options: a product transfer with your existing lender or a remortgage to a new lender. A product transfer, sometimes called a product switch, means staying with your current lender but moving onto a new interest rate and terms, often without further affordability checks or valuations. In contrast, a remortgage involves taking out an entirely new mortgage with a different lender, which typically necessitates a full application process, including comprehensive affordability assessments, property valuations, and legal conveyancing.
From August 2026, the Bank of England base rate is 3.75%, which will influence the new rates available whether you transfer or remortgage. Product transfers are generally quicker, often processed in a few weeks, sometimes even online, with minimal paperwork. Remortgaging, on the other hand, usually takes longer, typically 2-3 months, due to the detailed underwriting and legal work involved.
## What are the Pros and Cons for Speed and Fees?
Product transfers offer significant advantages in terms of speed and lower upfront costs. Because you remain with your existing lender, the process avoids a new valuation and legal fees, which are standard for a remortgage. Lenders often offer product transfers to existing clients with reduced administration. However, the interest rates available might not be the most competitive in the market, as they are not compelled to win your business against other lenders.
Remortgaging, while slower and more costly upfront, can often secure a more favourable interest rate, especially with the current Bank of England base rate at 3.75%. It also provides an opportunity to release equity for other investments, such as refurbishing another property, as lenders conduct a new valuation. This involves solicitors' fees, valuation fees (which can be £300-£700 depending on property value), and potentially new arrangement fees from the new lender. For example, a remortgage on a £250,000 property might incur £500 in legal fees and a £350 valuation fee, plus a product arrangement fee that could be £999 or 1% of the loan amount.
## How Does Equity Release Factor into This Decision?
Releasing equity is a key consideration, particularly if you plan to fund refurbishment of another property. A product transfer typically does not allow for additional borrowing or equity release beyond the original mortgage amount, as it's primarily a rate switch. If your goal is to access funds from your current property's accumulated equity, a remortgage is usually the more appropriate route. When remortgaging, the new lender will assess your affordability based on current rental income, using interest cover ratio (ICR) stress tests, which can be 125% or even 140% rental coverage at a notional 5.5% pay rate. This will determine how much you can borrow.
For instance, if your property is valued at £300,000 with an outstanding mortgage of £150,000, and you want to release £50,000, a remortgage allows you to apply for a new mortgage of £200,000 (assuming an 80% LTV, common for BTL). A product transfer would not facilitate this release of funds. The funds released can be used for various investment purposes, such as covering the costs of a significant renovation on another property, potentially increasing its rental yield or capital value.
## Does This Affect All Buy-to-Let Properties?
These considerations apply to all privately-owned buy-to-let properties, whether held in your personal name or within a limited company. For limited company BTL mortgages, the process and criteria for both product transfers and remortgages are similar, though lenders offering limited company finance may have different product ranges and fees. The key factor is the purpose: if you are simply looking for a new rate, a product transfer is quicker. If you need to raise capital, a remortgage is necessary. Remember that since April 2020, individual landlords cannot deduct mortgage interest from rental income; instead, they receive a 20% tax credit on finance costs, which impacts affordability assessments for new borrowing.
## Investor Rule of Thumb
Prioritise speed and minimal fees with a product transfer if you only need a new rate; choose a remortgage for equity release or to secure a potentially better rate, understanding the associated time and cost implications.
## What This Means For You
Most landlords want to make sound financial decisions that support their portfolio growth. Understanding the nuances between a product transfer and a remortgage is essential for optimising your capital and securing the best terms for your investment properties. If you're looking to strategically release equity to fund your next refurbishment project, knowing the right pathway can save you time and money.

Steven's Take
With your BTL mortgage coming up for renewal, it's a critical junction for your portfolio. If the goal is purely to secure a new rate with minimal fuss, a product transfer is often the sensible, quick option. However, if you're actively looking to grow your portfolio by funding a refurbishment through equity release, the remortgage route, despite the added time and cost, is usually the only way to achieve that. Don't let the convenience of a product transfer stop you from exploring better market rates or vital capital for your next project. Always compare the overall cost, including fees, against the interest rate to get the true picture. The Bank of England base rate at 3.75% means there can be significant differences in offerings, so shop around.
What You Can Do Next
Contact your current lender: Inquire about their product transfer rates and any associated fees for your specific BTL mortgage. Understand their full product switch offer.
Engage a specialist BTL mortgage broker: They can compare the market for remortgage products, rates, and fees, including options for equity release. They will assess your eligibility based on current lender ICR stress tests (e.g., 125% at 5.5% notional rate).
Request a decision in principle (DIP) for remortgage: This will give you an indication of how much equity you can release and at what rate without impacting your credit score significantly.
Calculate total costs for both options: Include arrangement fees, valuation fees (typically £300-£700 for a remortgage), legal fees (e.g., £500 for a remortgage), and potential early repayment charges (ERCs) if applicable, for both scenarios.
Review your refurbishment budget: Ensure the equity you plan to release from a remortgage adequately covers the costs of the planned refurbishment on your other property. Do not rely on estimates; obtain firm quotes for the work.
