Remortgaging means switching your existing mortgage to a new deal, either with your current lender or with a different one. It is one of the most common financial decisions homeowners make and can potentially save a significant amount of money, particularly when your current fixed-rate or discounted deal is coming to an end and you are about to roll onto the lender's standard variable rate.

This guide explains when remortgaging makes sense, how the process works, the costs involved, and when it may not be the right move.

Why People Remortgage

To get a better interest rate

The most common reason is to move from a standard variable rate, which is often significantly higher than the deals available to new or remortgaging borrowers, onto a new fixed or tracker rate deal. If your initial fixed rate has ended and you have not yet arranged a new deal, you are almost certainly paying more than necessary. Comparing the market for a competitive new deal can reduce monthly payments meaningfully.

To release equity

If your property has increased in value since you bought it, or since your last mortgage, you have built up equity. Remortgaging to borrow more than your current outstanding balance allows you to release some of that equity as cash. This is commonly used to fund home improvements, consolidate other debts, or for other major expenditure. The additional borrowing increases your monthly payments and the total interest you pay, so it needs to be considered carefully.

To consolidate debts

Some homeowners remortgage to consolidate higher-interest unsecured debts such as credit cards or personal loans into their mortgage. The mortgage interest rate is lower than typical credit card rates, so the monthly cost can reduce. However, spreading short-term debt over a 20 or 25-year mortgage term means you pay considerably more interest in total even at a lower rate. Debt consolidation through remortgaging requires careful calculation rather than simply comparing the interest rates.

To change the mortgage term or type

Remortgaging can also be used to change from a repayment mortgage to an interest-only mortgage or vice versa, to extend or shorten the mortgage term, or to add or remove a borrower from the mortgage.

When You Can Remortgage

You can apply to remortgage at any time, but the best time from a cost perspective depends on your current deal.

When a fixed rate or deal period is ending

The best time to start looking is three to six months before your current deal ends. Most mortgage offers are valid for three to six months, so starting the process early means you can secure a new rate before your current deal expires without any gap. If you wait until after your deal has ended, you will typically be paying the lender's standard variable rate while the remortgage is processed.

When you are on the standard variable rate

If you are already on the standard variable rate, remortgaging to a new deal should be a priority, as the SVR is almost always higher than the best available fixed or tracker rates.

Before a fixed rate ends

If you want to remortgage during a fixed rate period, you will typically face an early repayment charge for breaking the deal early. These charges are usually a percentage of the outstanding balance and can be substantial, often between one and five percent. The saving from remortgaging early needs to outweigh the early repayment charge for it to be financially worthwhile.

The Remortgaging Process

The process of remortgaging is broadly similar to applying for your original mortgage, though it is usually faster and involves less legal work since the property is already owned.

1. Research available deals. Compare deals from your existing lender (a product transfer) and from other lenders. A mortgage broker can search the market and advise on the best options for your circumstances.
2. Apply for the new mortgage. Complete the application with the new lender, providing income evidence, bank statements, and details of your outgoings for affordability assessment.
3. Valuation. The new lender will conduct a valuation of the property to confirm the current value, which determines your loan-to-value ratio and the rates available to you.
4. Legal work. A solicitor or conveyancer will handle the legal transfer of the mortgage from the old lender to the new one. Many remortgage products come with free legal work included. The process is simpler than an original purchase as there is no chain and no title transfer of ownership.
5. Completion. The new mortgage funds are used to repay the existing lender. Your mortgage moves to the new deal and new lender.

Costs to Consider

• Early repayment charge. If breaking a current fixed deal, this can be the most significant cost. Check the amount carefully before proceeding.
• Arrangement or product fee. Many competitive mortgage deals carry an arrangement fee, often between 500 and 2,000 pounds. This can be added to the mortgage, though doing so means you pay interest on it for the term.
• Valuation fee. Some lenders charge for the valuation; others offer free valuations as part of the deal.
• Legal fees. Many remortgages include free legal work. Where they do not, conveyancing fees for a remortgage are typically lower than for a purchase.

When Remortgaging May Not Make Sense

Remortgaging is not always beneficial. If your current deal has a large early repayment charge that exceeds any potential saving, staying put until the deal ends is better. If your property value has fallen and your loan-to-value ratio has increased significantly, you may find yourself in a less favourable rate band than you expected. And if your income or credit position has changed since your original mortgage, the new affordability assessment may produce a lower offer than you currently have.

Summary

Yes, you can remortgage your house and doing so at the right time can save a meaningful amount of money. The most common trigger is a fixed-rate deal ending, at which point comparing the market and switching to a new competitive deal is straightforward and often financially worthwhile. The process typically takes four to eight weeks and is simpler than the original purchase. Comparing costs carefully, including any early repayment charges, arrangement fees, and the total cost of the new deal over its term, gives you the information to make the right decision.
