When and Why to Remortgage in the UK: A Practical Guide for Homeowners

When and Why to Remortgage in the UK

Remortgaging is one of the most effective ways for homeowners in the UK to reduce costs, access equity, or adjust their financial plans.
Essentially, it means switching your current mortgage to a new deal — either with your existing lender (a product transfer) or a new one.
Many homeowners remortgage every few years to benefit from better rates or adapt to life changes such as income shifts, renovations, or debt consolidation.

In this guide, we’ll explain when remortgaging makes sense, what to consider before switching, and how to choose between staying with your lender or moving to a new one.

What Is a Remortgage

A remortgage is when you replace your existing mortgage with a new one, typically to secure a better interest rate, change your term, or release equity from your home.
You can remortgage to a new lender or do a product transfer — staying with your current lender but moving to a new deal when your fixed period ends.

The process usually involves a valuation, affordability check, and some legal work, though it’s simpler than buying a new property.

When to Consider a Remortgage

Here are the most common scenarios when remortgaging can benefit UK homeowners:

Your fixed rate is ending.
Most people remortgage when their initial fixed or discounted rate expires — usually after 2, 3, or 5 years — to avoid moving onto a higher Standard Variable Rate (SVR).
Interest rates have fallen.
If the Bank of England base rate or market rates drop, you might save hundreds (or even thousands) annually by remortgaging to a cheaper deal.
You want to borrow more.
Some homeowners remortgage to release equity — for home improvements, debt consolidation, or other major expenses.
Your property value has risen.
If your loan-to-value (LTV) has improved (for example, from 85% to 75%), you may qualify for better rates.
You’re changing financial circumstances.
Maybe your income has changed, you’ve become self-employed, or you need a more flexible deal — remortgaging can help realign your mortgage with your current life stage.

Product Transfers vs. Remortgaging to a New Lender

A product transfer is often the simplest option. Your existing lender offers you a new deal — no new application, valuation, or legal fees in most cases.
However, the downside is that you might miss out on better deals available elsewhere.

Switching to a new lender — a full remortgage — usually takes longer (2–6 weeks) but can yield significantly lower rates or more flexible terms.
A qualified mortgage adviser can compare both paths and calculate if the savings justify the switch.

Costs & Considerations

While remortgaging can save you money, it’s not always free. Common costs include:

Early repayment charges (ERCs): If you switch before your fixed term ends, lenders may charge between 1–5% of the balance.
Arrangement fees: Some low-rate deals include product fees up to £1,000+.
Valuation and legal fees: Some lenders offer “free legals” or cashback to cover these.
Exit fees: Small admin fees when closing your old mortgage.

Always ask your broker to calculate the true cost of switching — not just the advertised rate.

When Remortgaging Might Not Be the Right Move

Remortgaging isn’t always beneficial, for example:

If your outstanding balance is small (under £50,000), the fees might outweigh the benefits.
If you plan to move home soon — early exit fees could make remortgaging unwise.
If your credit score has worsened or your income is unstable, you might not qualify for better terms.

In these cases, a product transfer may be the smarter, simpler choice.

How to Prepare for a Successful Remortgage

✅ Check your credit score – clean up any old debts or missed payments.
✅ Review your property value – use lender tools or local agents.
✅ Gather documents early – income proofs, ID, bank statements.
✅ Start 3–6 months before your deal ends – avoid slipping onto the SVR.
✅ Speak to an independent adviser – they can compare deals across the market, not just one lender.
