Second Charge, the First Option

15 April 2026

A quiet shift is underway in the UK mortgage market, and it is being driven by borrowers, not lenders.

We are seeing more clients who are choosing to stay put, capital raise and improve and extend their homes, rather than move and pay more stamp duty and solicitor fees. While this may appear lifestyle-driven, it is increasingly a financially rational decision.

In this environment, second charge lending is increasingly becoming a first-choice consideration within the advice process, rather than an alternative explored after remortgage options.

Traditionally, remortgaging has been the default route when raising capital. However, in today’s market conditions, this approach is not always the most efficient or suitable option depending on individual circumstances, particularly where it results in unnecessary costs or, in some cases, moving clients into the specialist lending sector due to minor credit blips or lower credit scores, despite their existing mortgage remaining competitive. This approach is becoming increasingly difficult to justify in the current market.

Many borrowers remain tied into historically low fixed rates of 2%–3%, often with several years left. Breaking those deals can trigger significant ERCs before factoring in higher repayments.

More importantly, moving an entire mortgage onto a 6% or 7% rate to raise a relatively small amount of capital can dramatically increase overall costs.

The key question should be: why refinance the whole balance when only additional borrowing is required?

This is where second charge lending is becoming the more efficient starting point in many cases. Rather than disturbing a competitive first mortgage, a second charge allows additional borrowing to sit alongside it in a structured and targeted way.

While rates are typically higher, they apply only to a smaller portion of debt, often resulting in a lower blended cost – particularly once ERCs are considered.

It is not uncommon to see significant costs incurred when remortgaging purely to raise £15,000–£50,000 via remortgage. In many such cases, a second charge is significantly more cost-effective.

The second charge market has evolved significantly. Increased lender appetite, widespread use of AVMs, streamlined underwriting and greater lender competition. What once took 4–6 weeks can now, in some cases, complete in as little as a week, even rivalling bridging loans in terms of speed.

Product flexibility has also improved, with features such as tailored ERC structures and unlimited overpayments giving borrowers more control.

For example, borrowers can now secure five-year fixed rates with shorter ERC periods, allowing flexibility if circumstances change.

The current cost-of-living environment is also driving demand. Many households are carrying high-interest unsecured debt, from credit cards to personal loans. Second charges can provide a structured way to consolidate borrowing, reduce monthly outgoings and improve credit profiles over time.

They are often used as a medium-term solution – typically two to five years – aligning with the remaining term of a client’s existing mortgage.

Another key use case is adverse credit. Instead of moving the entire mortgage onto a higher-rate specialist product, brokers can retain the existing first charge and address the issue through a second charge. This avoids unnecessarily increasing costs across the full balance.

None of this is to suggest remortgaging does not have a role. In many scenarios, it remains the right solution. But suitability, not habit, should drive advice.

The growth of the second charge market reflects a broader shift. These products are no longer niche or last resort; they are a mainstream tool within the adviser toolkit.

The market has moved on. Borrowers are more informed, more cost-conscious, and focused on protecting existing low rates.

For brokers, the opportunity is not to replace remortgaging, but to reframe the conversation.

Because the key question is no longer “can we remortgage?” but “should we?”
