What Is Remortgaging?
Remortgaging is the process of switching your existing mortgage to a new deal - either with your current lender or a different one - without moving home. A remortgage replaces the existing mortgage with a new one, typically to access a better interest rate, release equity, or change the mortgage term or type.
The most common reason to remortgage is to avoid reverting to a lender's standard variable rate (SVR) when a fixed-rate or tracker deal expires. SVRs are typically 2 to 4 percent higher than the best available fixed rates, making an SVR reversion one of the most expensive financial events in a homeowner's calendar.
Remortgaging is also used to release equity from the property - borrowing more than the current outstanding balance to fund home improvements, consolidate debts, or provide a deposit for a second property. Understanding the full range of remortgage options enables homeowners to make decisions that significantly reduce their mortgage costs over time.
When Should You Remortgage?
The optimal time to remortgage is before your current deal expires - typically six months before the end date. Most lenders allow you to lock in a new rate up to six months in advance, so starting the remortgage process early protects against rate rises while avoiding any early repayment charge on the existing deal.
Borrowers currently sitting on their lender's SVR should remortgage immediately, as SVRs are almost always significantly higher than available fixed rates. The financial cost of staying on SVR for even six months can exceed 1,000 to 3,000 pounds on a typical mortgage.
Other situations where remortgaging makes sense include: the property has increased significantly in value, improving the LTV ratio and unlocking better rates; income has increased, enabling a shorter term or more competitive product; or a major life event such as separation requires removing a name from the mortgage. Each of these situations benefits from a remortgage review even outside the standard deal-end cycle.
How the Remortgage Process Works
The remortgage process begins with a comparison of available products across the market. A whole-of-market mortgage broker compares all lenders simultaneously, including exclusive products unavailable directly to consumers. The remortgage process typically takes four to eight weeks from application to completion.
For a remortgage to a new lender, a full mortgage application is required including income verification, credit assessment, and a property valuation. The new lender's solicitor or a panel firm handles the legal transfer of the mortgage charge. Many lenders offer free valuation and free legal work as part of their remortgage package.
For a product transfer with the existing lender - switching to a new rate without changing lender - the process is simpler. Under the FCA Mortgage Charter, lenders must allow product transfers at the end of a fixed period without a new affordability assessment. Product transfers can often be completed online in minutes, though the rate available may not be as competitive as the wider market.
Remortgage Costs: What to Budget For
The costs of a remortgage depend on whether you are switching lenders or doing a product transfer with your existing lender. A product transfer with the existing lender typically has no fees - no arrangement fee, no legal fee, no valuation fee. A remortgage to a new lender carries more costs but typically offers better rates.
Arrangement fees on remortgage products range from zero to 2,000 pounds. A fee-free product has a higher interest rate; a product with a 999 pound fee has a lower rate. The break-even calculation - how long until the lower rate saves more than the fee - determines which is cheaper over the product term. On a 200,000 pound mortgage, a 0.2 percent rate reduction saves approximately 400 pounds per year, meaning a 999 pound fee breaks even in about 2.5 years.
Legal fees for a remortgage to a new lender are typically 300 to 700 pounds, though many lenders offer free legal work through a panel solicitor. Valuation fees are similarly often waived on remortgage deals. Exit fees from the existing lender - not to be confused with early repayment charges - are typically 50 to 200 pounds and are disclosed in the original mortgage documentation.
Remortgage to Release Equity
Remortgaging to release equity involves borrowing more than the current outstanding balance when switching lenders. The additional funds are paid to the borrower as cash. This is distinct from equity release products designed for older borrowers; a remortgage to release equity is a standard mortgage available to borrowers of all ages who meet normal lending criteria.
The maximum equity that can be released depends on the lender's maximum LTV (typically 80 to 85 percent) and the affordability of the higher mortgage payment. On a 400,000 pound property with an existing 200,000 pound mortgage and a maximum LTV of 80 percent, up to 120,000 pounds can be released.
Common uses for equity released through a remortgage include: home improvements (kitchen, extension, loft conversion), deposit for a buy-to-let or second property, university fees, debt consolidation, and gifting a deposit to children. The released equity is borrowed at mortgage rates, which are typically lower than personal loan or credit card rates, but the debt is secured against the home.
Remortgage with the Same Lender vs Switching
Staying with the same lender for a product transfer is simpler and faster than switching lenders. There is no new credit assessment, no valuation, and no legal work. Product transfers can often be arranged online within minutes. For straightforward cases where the existing lender's rate is competitive, a product transfer is the most efficient option.
Switching lenders on remortgage takes more time and involves more paperwork but typically accesses the full market rate range including exclusive broker products. A whole-of-market broker can compare the existing lender's product transfer rate against all available remortgage products simultaneously, making the best choice straightforward.
The rate difference between the best product transfer rate and the best remortgage rate from a new lender is often 0.1 to 0.3 percent. On a 250,000 pound mortgage, this is 250 to 750 pounds per year. Whether this saving justifies the additional work of switching lenders depends on the specific rate difference and the borrower's appetite for the process.
Remortgage with Bad Credit
Remortgaging with adverse credit history is more complex than a standard remortgage but remains possible through specialist lenders. The key factors are the type and recency of the adverse credit, the LTV ratio, and whether the existing mortgage payments have been maintained throughout.
Borrowers who have maintained their existing mortgage payments throughout a period of financial difficulty are in a stronger position for a remortgage than those who have fallen into arrears. A clean payment record on the mortgage itself demonstrates credit reliability in the most relevant area.
A specialist adverse credit mortgage broker with access to specialist remortgage lenders is essential for this situation. Applying to mainstream lenders without specialist knowledge risks declined applications and credit file damage from multiple hard searches. The specialist broker can identify the most appropriate lender, prepare the application effectively, and target a single application to maximise the probability of approval.
How to Find the Best Remortgage Deal
Finding the best remortgage deal requires comparing products across the whole market - not just the deals advertised by major banks. A whole-of-market mortgage broker has access to all lenders including challenger banks, building societies, and specialist lenders whose products are not available through comparison websites.
Key factors in comparing remortgage deals: the initial rate for the fixed or tracker period; the arrangement fee (and whether adding it to the loan is cost-effective); the ERC structure if you might need to exit early; the product term (two-year vs five-year fixed); and the SVR that applies after the initial period expires.
Starting the remortgage comparison six months before the current deal ends provides maximum flexibility. Rates can be locked in immediately to protect against rises, or monitoring can continue if rates appear to be falling. A whole-of-market mortgage broker manages this timeline, alerts the borrower to significant rate movements, and handles the full application process through to completion.

Frequently Asked Questions
When should I remortgage?
Start the remortgage process six months before your current deal expires. This allows time to compare the market and lock in a rate before your existing deal ends, avoiding any gap on the SVR. If you are already on the SVR, remortgage immediately - you are likely paying significantly more than necessary.
How long does a remortgage take?
A remortgage to a new lender typically takes four to eight weeks from application to completion. A product transfer with the existing lender can be completed in days or even minutes online. Starting the process six months before your deal ends provides ample time.
Does remortgaging affect your credit score?
A remortgage application involves a hard credit search which temporarily reduces the score by a small amount. Successfully completing a remortgage and making payments on time has a neutral to positive long-term effect on the credit profile.
Can I remortgage early?
Yes, but you may face an early repayment charge. The ERC must be weighed against the saving from the new rate. If rates have fallen significantly, paying an ERC to access a materially lower rate can still produce a net financial benefit. A mortgage broker can model the break-even calculation.
What documents do I need to remortgage?
Standard remortgage documents: last three months payslips or two to three years SA302 for self-employed, three months bank statements, latest P60, and proof of address. Product transfers with the existing lender typically require no documentation.
Is it worth remortgaging for a small rate difference?
It depends on the loan size. On a 300,000 pound mortgage, a 0.2 percent rate saving is 600 pounds per year - worth pursuing even accounting for arrangement fees. On a 100,000 pound mortgage, the same rate saving is 200 pounds per year, which may not justify switching fees.
Can I remortgage to release equity?
Yes. A remortgage to release equity borrows more than the current outstanding balance. The additional funds are released as cash. The maximum depends on the lender's LTV limit and your affordability at the higher loan amount.
